Tips & Tricks {#tips}
|

=============
|
||||
|
||||
Blank Variable Handling {#tips.blank.var.handling}
|
||||
=======================
|
||||
|
||||
There may be times when you want to print a default value for an empty
|
||||
variable instead of printing nothing, such as printing ` ` so that
|
||||
html table backgrounds work properly. Many would use an
|
||||
[`{if}`](#language.function.if) statement to handle this, but there is a
|
||||
shorthand way with Smarty, using the
|
||||
[`default`](#language.modifier.default) variable modifier.

||||

||||

Default Variable Handling {#tips.default.var.handling}
|
||||
=========================
|
||||
|
||||
If a variable is used frequently throughout your templates, applying the
|
||||
[`default`](#language.modifier.default) modifier every time it is
|
||||
mentioned can get a bit ugly. You can remedy this by assigning the
|
||||
variable its default value with the
|
||||
[`{assign}`](#language.function.assign) function.
|
||||
|
||||
|
||||
{* do this somewhere at the top of your template *}
|
||||
{assign var='title' value=$title|default:'no title'}
|
||||
|
||||
{* if $title was empty, it now contains the value "no title" when you use it *}
|
||||
{$title}
|
||||
|
||||
|
||||
|
||||
See also [`default`](#language.modifier.default) modifier and [blank
|
||||
variable handling](#tips.blank.var.handling).
|
||||
|
||||
Passing variable title to header template {#tips.passing.vars}
|
||||
=========================================
|
||||
|
||||
When the majority of your templates use the same headers and footers, it
|
||||
is common to split those out into their own templates and
|
||||
[`{include}`](#language.function.include) them. But what if the header
|
||||
needs to have a different title, depending on what page you are coming
|
||||
from? You can pass the title to the header as an
|
||||
[attribute](#language.syntax.attributes) when it is included.
|
||||
|
||||
`mainpage.tpl` - When the main page is drawn, the title of "Main Page"
|
||||
is passed to the `header.tpl`, and will subsequently be used as the
|
||||
title.
|
||||
|
||||
|
||||
{include file='header.tpl' title='Main Page'}
|
||||
{* template body goes here *}
|
||||
{include file='footer.tpl'}
|
||||
|
||||
|
||||
|
||||
`archives.tpl` - When the archives page is drawn, the title will be
|
||||
"Archives". Notice in the archive example, we are using a variable from
|
||||
the `archives_page.conf` file instead of a hard coded variable.
|
||||
|
||||
|
||||
{config_load file='archive_page.conf'}
|
||||
|
||||
{include file='header.tpl' title=#archivePageTitle#}
|
||||
{* template body goes here *}
|
||||
{include file='footer.tpl'}
|
||||
|
||||
|
||||
|
||||
`header.tpl` - Notice that "Smarty News" is printed if the `$title`
|
||||
variable is not set, using the [`default`](#language.modifier.default)
|
||||
variable modifier.
|
||||
|
||||
|
||||
<html>
|
||||
<head>
|
||||
<title>{$title|default:'Smarty News'}</title>
|
||||
</head>
|
||||
<body>
|
||||
|
||||
|
||||
|
||||
`footer.tpl`
|
||||
|
||||
|
||||
</body>
|
||||
</html>

Dates {#tips.dates}
|
||||
=====
|
||||
|
||||
As a rule of thumb, always pass dates to Smarty as
|
||||
[timestamps](&url.php-manual;time). This allows template designers to
|
||||
use the [`date_format`](#language.modifier.date.format) modifier for
|
||||
full control over date formatting, and also makes it easy to compare
|
||||
dates if necessary.
|
||||
|
||||
|
||||
{$startDate|date_format}
|
||||
|
||||
|
||||
|
||||
This will output:
|
||||
|
||||
|
||||
Jan 4, 2009
|
||||
|
||||
|
||||
|
||||
|
||||
{$startDate|date_format:"%Y/%m/%d"}
|
||||
|
||||
|
||||
|
||||
This will output:
|
||||
|
||||
|
||||
2009/01/04
|
||||
|
||||
|
||||
|
||||
Dates can be compared in the template by timestamps with:
|
||||
|
||||
|
||||
{if $order_date < $invoice_date}
|
||||
...do something..
|
||||
{/if}
|
||||
|
||||
|
||||
|
||||
When using [`{html_select_date}`](#language.function.html.select.date)
|
||||
in a template, the programmer will most likely want to convert the
|
||||
output from the form back into timestamp format. Here is a function to
|
||||
help you with that.
|
||||
|
||||
|
||||
<?php
|
||||
|
||||
// this assumes your form elements are named
|
||||
// startDate_Day, startDate_Month, startDate_Year
|
||||
|
||||
$startDate = makeTimeStamp($startDate_Year, $startDate_Month, $startDate_Day);
|
||||
|
||||
function makeTimeStamp($year='', $month='', $day='')
|
||||
{
|
||||
if(empty($year)) {
|
||||
$year = strftime('%Y');
|
||||
}
|
||||
if(empty($month)) {
|
||||
$month = strftime('%m');
|
||||
}
|
||||
if(empty($day)) {
|
||||
$day = strftime('%d');
|
||||
}
|
||||
|
||||
return mktime(0, 0, 0, $month, $day, $year);
|
||||
}
|
||||
?>

Componentized Templates {#tips.componentized.templates}
|
||||
=======================
|
||||
|
||||
Traditionally, programming templates into your applications goes as
|
||||
follows: First, you accumulate your variables within your PHP
|
||||
application, (maybe with database queries.) Then, you instantiate your
|
||||
Smarty object, [`assign()`](#api.assign) the variables and
|
||||
[`display()`](#api.display) the template. So lets say for example we
|
||||
have a stock ticker on our template. We would collect the stock data in
|
||||
our application, then assign these variables in the template and display
|
||||
it. Now wouldn't it be nice if you could add this stock ticker to any
|
||||
application by merely including the template, and not worry about
|
||||
fetching the data up front?
|
||||
|
||||
You can do this by writing a custom plugin for fetching the content and
|
||||
assigning it to a template variable.
|
||||
|
||||
`function.load_ticker.php` - drop file in
|
||||
[`$plugins directory`](#variable.plugins.dir)
|
||||
|
||||
|
||||
<?php
|
||||
|
||||
// setup our function for fetching stock data
|
||||
function fetch_ticker($symbol)
|
||||
{
|
||||
// put logic here that fetches $ticker_info
|
||||
// from some ticker resource
|
||||
return $ticker_info;
|
||||
}
|
||||
|
||||
function smarty_function_load_ticker($params, $smarty)
|
||||
{
|
||||
// call the function
|
||||
$ticker_info = fetch_ticker($params['symbol']);
|
||||
|
||||
// assign template variable
|
||||
$smarty->assign($params['assign'], $ticker_info);
|
||||
}
|
||||
?>
|
||||
|
||||
|
||||
|
||||
`index.tpl`
|
||||
|
||||
|
||||
{load_ticker symbol='SMARTY' assign='ticker'}
|
||||
|
||||
Stock Name: {$ticker.name} Stock Price: {$ticker.price}

||||

||||

Obfuscating E-mail Addresses {#tips.obfuscating.email}
|
||||
============================
|
||||
|
||||
Do you ever wonder how your email address gets on so many spam mailing
|
||||
lists? One way spammers collect email addresses is from web pages. To
|
||||
help combat this problem, you can make your email address show up in
|
||||
scrambled javascript in the HTML source, yet it it will look and work
|
||||
correctly in the browser. This is done with the
|
||||
[`{mailto}`](#language.function.mailto) plugin.
|
||||
|
||||
|
||||
<div id="contact">Send inquiries to
|
||||
{mailto address=$EmailAddress encode='javascript' subject='Hello'}
|
||||
</div>
|
||||
|
||||
|
||||

||||
> **Note**
|
||||

|
||||

|
||||

Troubleshooting
|
||||
===============
|
||||
|
||||
Smarty/PHP errors {#smarty.php.errors}
|
||||
=================
|
||||
|
||||
Smarty can catch many errors such as missing tag attributes or malformed
|
||||
variable names. If this happens, you will see an error similar to the
|
||||
following:
|
||||
|
||||
|
||||
Warning: Smarty: [in index.tpl line 4]: syntax error: unknown tag - '%blah'
|
||||
in /path/to/smarty/Smarty.class.php on line 1041
|
||||
|
||||
Fatal error: Smarty: [in index.tpl line 28]: syntax error: missing section name
|
||||
in /path/to/smarty/Smarty.class.php on line 1041
|
||||
|
||||
|
||||
|
||||
Smarty shows you the template name, the line number and the error. After
|
||||
that, the error consists of the actual line number in the Smarty class
|
||||
that the error occurred.
|
||||
|
||||
There are certain errors that Smarty cannot catch, such as missing close
|
||||
tags. These types of errors usually end up in PHP compile-time parsing
|
||||
errors.
|
||||
|
||||
|
||||
Parse error: parse error in /path/to/smarty/templates_c/index.tpl.php on line 75
|
||||
|
||||
|
||||
|
||||
When you encounter a PHP parsing error, the error line number will
|
||||
correspond to the compiled PHP script, NOT the template itself. Usually
|
||||
you can look at the template and spot the syntax error. Here are some
|
||||
common things to look for: missing close tags for
|
||||
[`{if}{/if}`](#language.function.if) or
|
||||
[`{section}{/section}`](#language.function.if), or syntax of logic
|
||||
within an `{if}` tag. If you can\'t find the error, you might have to
|
||||
open the compiled PHP file and go to the line number to figure out where
|
||||
the corresponding error is in the template.
|
||||
|
||||
|
||||
Warning: Smarty error: unable to read resource: "index.tpl" in...
|
||||
or

||||

|
||||
|
||||
- A [`{config_load}`](#language.function.config.load) function is
|
||||
within a template (or [`configLoad()`](#api.config.load) has been
|
||||
called) and either [`$config_dir`](#variable.config.dir) is
|
||||
incorrect, does not exist or `site.conf` is not in the directory.

Escaping Smarty Parsing {#language.escaping}
|
||||
=======================
|
||||
|
||||
It is sometimes desirable or even necessary to have Smarty ignore
|
||||
sections it would otherwise parse. A classic example is embedding
|
||||
Javascript or CSS code in a template. The problem arises as those
|
||||
languages use the { and } characters which are also the default
|
||||
[delimiters](#language.function.ldelim) for Smarty.
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> A good practice for avoiding escapement altogether is by separating
|
||||
> your Javascript/CSS into their own files and use standard HTML methods
|
||||
> to access them. This will also take advantage of browser script
|
||||
> caching. When you need to embed Smarty variables/functions into your
|
||||
> Javascript/CSS, then the following applies.
|
||||
|
||||
In Smarty templates, the { and } braces will be ignored so long as they
|
||||
are surrounded by white space. This behavior can be disabled by setting
|
||||
the Smarty class variable [`$auto_literal`](#variable.auto.literal) to
|
||||
false.
|
||||
|
||||
|
||||
<script>
|
||||
// the following braces are ignored by Smarty
|
||||
// since they are surrounded by whitespace
|
||||
function foobar {
|
||||
alert('foobar!');
|
||||
}
|
||||
// this one will need literal escapement
|
||||
{literal}
|
||||
function bazzy {alert('foobar!');}
|
||||
{/literal}
|
||||
</script>
|
||||
|
||||
|
||||
|
||||
[`{literal}..{/literal}`](#language.function.literal) blocks are used
|
||||
for escaping blocks of template logic. You can also escape the braces
|
||||
individually with
|
||||
[`{ldelim}`](#language.function.ldelim),[`{rdelim}`](#language.function.ldelim)
|
||||
tags or
|
||||
[`{$smarty.ldelim}`,`{$smarty.rdelim}`](#language.variables.smarty.ldelim)
|
||||
variables.
|
||||
|
||||
Smarty\'s default delimiters { and } cleanly represent presentational
|
||||
content. However if another set of delimiters suit your needs better,
|
||||
you can change them with Smarty\'s
|
||||
[`$left_delimiter`](#variable.left.delimiter) and
|
||||
[`$right_delimiter`](#variable.right.delimiter) values.
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> Changing delimiters affects ALL template syntax and escapement. Be
|
||||
> sure to clear out cache and compiled files if you decide to change
|
||||
> them.

Functions {#language.syntax.functions}
|

=========

invokes some sort of function. These are processed and displayed by

within delimiters like so: `{funcname attr1="val1" attr2="val2"}`.

[`{strip}`](#language.function.strip). There should be no need to

- Custom functions are **additional** functions implemented via

create new ones. [`{html_options}`](#language.function.html.options)

|

and under\_scores. See [naming](&url.php-manual;language.variables)
|

for more detail.
|
||||
|
||||
- With any other characters, for example a period(.) or
|
||||
`$object->reference`, then the variable must be surrounded by
|
||||
`` `backticks` ``.
|
||||
|
||||
- In addition Smarty3 does allow embedded Smarty tags in double quoted
|
||||
strings. This is useful if you want to include variables with
|
||||
modifiers, plugin or PHP function results.

Variables {#language.syntax.variables}
|
||||
=========
|
||||
|
||||
Template variables start with the \$dollar sign. They can contain
|
||||
numbers, letters and underscores, much like a [PHP
|
||||
variable](&url.php-manual;language.variables). You can reference arrays
|
||||
by index numerically or non-numerically. Also reference object
|
||||
properties and methods.
|
||||
|
||||
[Config file variables](#language.config.variables) are an exception to
|
||||
the \$dollar syntax and are instead referenced with surrounding
|
||||
\#hashmarks\#, or via the
|
||||
[`$smarty.config`](#language.variables.smarty.config) variable.
|
||||
|
||||
|
||||
{$foo} <-- displaying a simple variable (non array/object)
|
||||
{$foo[4]} <-- display the 5th element of a zero-indexed array
|
||||
{$foo.bar} <-- display the "bar" key value of an array, similar to PHP $foo['bar']
|
||||
{$foo.$bar} <-- display variable key value of an array, similar to PHP $foo[$bar]
|
||||
{$foo->bar} <-- display the object property "bar"
|
||||
{$foo->bar()} <-- display the return value of object method "bar"
|
||||
{#foo#} <-- display the config file variable "foo"
|
||||
{$smarty.config.foo} <-- synonym for {#foo#}
|
||||
{$foo[bar]} <-- syntax only valid in a section loop, see {section}
|
||||
{assign var=foo value='baa'}{$foo} <-- displays "baa", see {assign}
|
||||
|
||||
Many other combinations are allowed
|
||||
|
||||
{$foo.bar.baz}
|
||||
{$foo.$bar.$baz}
|
||||
{$foo[4].baz}
|
||||
{$foo[4].$baz}
|
||||
{$foo.bar.baz[4]}
|
||||
{$foo->bar($baz,2,$bar)} <-- passing parameters
|
||||
{"foo"} <-- static values are allowed
|
||||
|
||||
{* display the server variable "SERVER_NAME" ($_SERVER['SERVER_NAME'])*}
|
||||
{$smarty.server.SERVER_NAME}
|
||||
|
||||
Math and embedding tags:
|
||||
|
||||
{$x+$y} // will output the sum of x and y.
|
||||
{assign var=foo value=$x+$y} // in attributes
|
||||
{$foo[$x+3]} // as array index
|
||||
{$foo={counter}+3} // tags within tags
|
||||
{$foo="this is message {counter}"} // tags within double quoted strings
|
||||
|
||||
Defining Arrays:
|
||||
|
||||
{assign var=foo value=[1,2,3]}
|
||||
{assign var=foo value=['y'=>'yellow','b'=>'blue']}
|
||||
{assign var=foo value=[1,[9,8],3]} // can be nested
|
||||
|
||||
Short variable assignment:
|
||||
|
||||
{$foo=$bar+2}
|
||||
{$foo = strlen($bar)} // function in assignment
|
||||
{$foo = myfunct( ($x+$y)*3 )} // as function parameter
|
||||
{$foo.bar=1} // assign to specific array element
|
||||
{$foo.bar.baz=1}
|
||||
{$foo[]=1} // appending to an array
|
||||
|
||||
Smarty "dot" syntax (note: embedded {} are used to address ambiguities):
|
||||
|
||||
{$foo.a.b.c} => $foo['a']['b']['c']
|
||||
{$foo.a.$b.c} => $foo['a'][$b]['c'] // with variable index
|
||||
{$foo.a.{$b+4}.c} => $foo['a'][$b+4]['c'] // with expression as index
|
||||
{$foo.a.{$b.c}} => $foo['a'][$b['c']] // with nested index
|
||||
|
||||
PHP-like syntax, alternative to "dot" syntax:
|
||||
|
||||
{$foo[1]} // normal access
|
||||
{$foo['bar']}
|
||||
{$foo['bar'][1]}
|
||||
{$foo[$x+$x]} // index may contain any expression
|
||||
{$foo[$bar[1]]} // nested index
|
||||
{$foo[section_name]} // smarty {section} access, not array access!
|
||||
|
||||
Variable variables:
|
||||
|
||||
$foo // normal variable
|
||||
$foo_{$bar} // variable name containing other variable
|
||||
$foo_{$x+$y} // variable name containing expressions
|
||||
$foo_{$bar}_buh_{$blar} // variable name with multiple segments
|
||||
{$foo_{$x}} // will output the variable $foo_1 if $x has a value of 1.
|
||||
|
||||
Object chaining:
|
||||
|
||||
{$object->method1($x)->method2($y)}
|
||||
|
||||
Direct PHP function access:
|
||||
|
||||
{time()}

||||

||||

Smarty comes with several built-in functions. These built-in functions
|
||||
are the integral part of the smarty template engine. They are compiled
|
||||
into corresponding inline PHP code for maximum performance.
|
||||
|
||||
You cannot create your own [custom
|
||||
functions](./language-custom-functions.md) with the same name; and you
|
||||
should not need to modify the built-in functions.
|
||||
|
||||
A few of these functions have an `assign` attribute which collects the
|
||||
result the function to a named template variable instead of being
|
||||
output; much like the [`{assign}`](./language-builtin-functions/language-function-assign.md) function.

|
||||
{assign "foo" "bar" scope="global"} {* short-hand *}
|
||||
|
||||
|
||||
|
||||
To access `{assign}` variables from a php script use
|
||||
[`getTemplateVars()`](#api.get.template.vars). Here\'s the template that
|
||||
creates the variable `$foo`.
|
||||
|
||||
|
||||
{assign var="foo" value="Smarty"}
|
||||
|
||||
The template variables are only available after/during template
|
||||
execution as in the following script.
|
||||
|
||||
|
||||
<?php
|
||||
|
||||
// this will output nothing as the template has not been executed
|
||||
echo $smarty->getTemplateVars('foo');
|
||||
|
||||
// fetch the template to a variable
|
||||
$whole_page = $smarty->fetch('index.tpl');
|
||||
|
||||
// this will output 'smarty' as the template has been executed
|
||||
echo $smarty->getTemplateVars('foo');
|
||||
|
||||
$smarty->assign('foo','Even smarter');
|
||||
|
||||
// this will output 'Even smarter'
|
||||
echo $smarty->getTemplateVars('foo');
|

`{capture}` is used to collect the output of the template between the
|
||||
tags into a variable instead of displaying it. Any content between
|
||||
`{capture name='foo'}` and `{/capture}` is collected into the variable
|
||||
specified in the `name` attribute.
|
||||
|
||||
The captured content can be used in the template from the variable
|
||||
[`$smarty.capture.foo`](#language.variables.smarty.capture) where "foo"
|
||||
is the value passed in the `name` attribute. If you do not supply the
|
||||
`name` attribute, then "default" will be used as the name ie
|
||||
`$smarty.capture.default`.
|
||||
|

`{capture}'s` can be nested.

{extends} {#language.function.extends}
|

=========
|
||||
|

`{extends}` tags are used in child templates in template inheritance for
|
||||
extending parent templates. For details see section of [Template
|
||||
Inheritance](#advanced.features.template.inheritance).
|
||||
|
||||
- The `{extends}` tag must be on the first line of the template.
|
||||
|
||||
- If a child template extends a parent template with the `{extends}`
|
||||
tag it may contain only `{block}` tags. Any other template content
|
||||
is ignored.
|
||||
|
||||
- Use the syntax for [template resources](#resources) to extend files
|
||||
outside of the [`$template_dir`](#variable.template.dir) directory.
|
||||
|
||||
> **Note**
|

{foreach},{foreachelse} {#language.function.foreach}
|
||||
=======================
|
||||
|
||||
`{foreach}` is used for looping over arrays of data. `{foreach}` has a
|
||||
simpler and cleaner syntax than the
|
||||
[`{section}`](#language.function.section) loop, and can also loop over
|
||||
associative arrays.
|
||||
|
||||
`{foreach $arrayvar as $itemvar}`
|
||||
|
||||
`{foreach $arrayvar as $keyvar=>$itemvar}`
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> This foreach syntax does not accept any named attributes. This syntax
|
||||
> is new to Smarty 3, however the Smarty 2.x syntax
|
||||
> `{foreach from=$myarray key="mykey" item="myitem"}` is still
|
||||
> supported.
|
||||
|
||||
- `{foreach}` loops can be nested.
|
||||
|
||||
- The `array` variable, usually an array of values, determines the
|
||||
number of times `{foreach}` will loop. You can also pass an integer
|
||||
for arbitrary loops.
|
||||
|
||||
- `{foreachelse}` is executed when there are no values in the `array`
|
||||
variable.
|
||||
|
||||
- `{foreach}` properties are [`@index`](#foreach.property.index),
|
||||
[`@iteration`](#foreach.property.iteration),
|
||||
[`@first`](#foreach.property.first),
|
||||
[`@last`](#foreach.property.last),
|
||||
[`@show`](#foreach.property.show),
|
||||
[`@total`](#foreach.property.total).
|
||||
|
||||
- `{foreach}` constructs are [`{break}`](#foreach.construct.break),
|
||||
[`{continue}`](#foreach.construct.continue).
|
||||
|
||||
- Instead of specifying the `key` variable you can access the current
|
||||
key of the loop item by `{$item@key}` (see examples below).
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> The `$var@property` syntax is new to Smarty 3, however when using the
|
||||
> Smarty 2 `{foreach from=$myarray key="mykey" item="myitem"}` style
|
||||
> syntax, the `$smarty.foreach.name.property` syntax is still supported.
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> Although you can retrieve the array key with the syntax
|
||||
> `{foreach $myArray as $myKey => $myValue}`, the key is always

A database (PDO) example of looping over search results. This example is
|
||||
looping over a PHP iterator instead of an array().
|
||||
|
||||
|
||||
<?php
|
||||
include('Smarty.class.php');
|
||||
|
||||
$smarty = new Smarty;
|
||||
|
||||
$dsn = 'mysql:host=localhost;dbname=test';
|
||||
$login = 'test';
|
||||
$passwd = 'test';
|
||||
|
||||
// setting PDO to use buffered queries in mysql is
|
||||
// important if you plan on using multiple result cursors
|
||||
// in the template.
|
||||
|
||||
$db = new PDO($dsn, $login, $passwd, array(
|
||||
PDO::MYSQL_ATTR_USE_BUFFERED_QUERY => true));
|
||||
|
||||
$res = $db->prepare("select * from users");
|
||||
$res->execute();
|
||||
$res->setFetchMode(PDO::FETCH_LAZY);
|
||||
|
||||
// assign to smarty
|
||||
$smarty->assign('res',$res);
|
||||
|
||||
$smarty->display('index.tpl');?>
|
||||
?>
|
||||
|
||||
|
||||
|
||||
|
||||
{foreach $res as $r}
|
||||
{$r.id}
|
||||
{$r.name}
|
||||
{foreachelse}
|
||||
.. no results ..
|
||||
{/foreach}
|
||||
|
||||
|
||||
|
||||
The above is assuming the results contain the columns named `id` and
|
||||
`name`.
|
||||
|
||||
What is the advantage of an iterator vs. looping over a plain old array?
|
||||
With an array, all the results are accumulated into memory before being
|
||||
looped. With an iterator, each result is loaded/released within the
|
||||
loop. This saves processing time and memory, especially for very large
|
||||
result sets.
|
||||
|
||||
\@index {#foreach.property.index}
|
||||
-------
|
||||
|
||||
`index` contains the current array index, starting with zero.
|
||||
|
||||
|
||||
{* output empty row on the 4th iteration (when index is 3) *}
|
||||
<table>
|
||||
{foreach $items as $i}
|
||||
{if $i@index eq 3}
|
||||
{* put empty table row *}
|
||||
<tr><td>nbsp;</td></tr>
|
||||
{/if}
|
||||
<tr><td>{$i.label}</td></tr>
|
||||
{/foreach}
|
||||
</table>
|
||||
|
||||
|
||||
|
||||
\@iteration {#foreach.property.iteration}
|
||||
-----------
|
||||
|
||||
`iteration` contains the current loop iteration and always starts at
|
||||
one, unlike [`index`](#foreach.property.index). It is incremented by one
|
||||
on each iteration.
|
||||
|
||||
The *\"is div by\"* operator can be used to detect a specific iteration.
|
||||
Here we bold-face the name every 4th iteration.
|
||||
|
||||
|
||||
{foreach $myNames as $name}
|
||||
{if $name@iteration is div by 4}
|
||||
<b>{$name}</b>
|
||||
{/if}
|
||||
{$name}
|
||||
{/foreach}
|
||||
|
||||
The *\"is even by\"* and *\"is odd by\"* operators can be used to
|
||||
alternate something every so many iterations. Choosing between even or
|
||||
odd rotates which one starts. Here we switch the font color every 3rd
|
||||
iteration.
|
||||
|
||||
|
||||
{foreach $myNames as $name}
|
||||
{if $name@iteration is even by 3}
|
||||
<span style="color: #000">{$name}</span>
|
||||
{else}
|
||||
<span style="color: #eee">{$name}</span>
|
||||
{/if}
|
||||
{/foreach}
|
||||
|
||||
|
||||
|
||||
This will output something similar to this:
|
||||
|
||||
|
||||
<span style="color: #000">...</span>
|
||||
<span style="color: #000">...</span>
|

|
||||
<span style="color: #000">...</span>
|
||||
<span style="color: #000">...</span>
|
||||
<span style="color: #000">...</span>
|

<span style="color: #eee">...</span>
|

<span style="color: #eee">...</span>
|
||||
<span style="color: #eee">...</span>
|
||||
...
|
||||
|
||||
|
||||
|
||||
\@first {#foreach.property.first}
|
||||
-------
|
||||
|
||||
`first` is TRUE if the current `{foreach}` iteration is the initial one.
|
||||
Here we display a table header row on the first iteration.
|
||||
|
||||
|
||||
{* show table header at first iteration *}
|
||||
<table>
|
||||
{foreach $items as $i}
|
||||
{if $i@first}

|
||||
|
||||
|
||||
|
||||
\@last {#foreach.property.last}
|
||||
------
|
||||
|
||||
`last` is set to TRUE if the current `{foreach}` iteration is the final
|
||||
one. Here we display a horizontal rule on the last iteration.
|
||||
|
||||
|
||||
{* Add horizontal rule at end of list *}

|

|
||||
|
||||
|
||||
\@show {#foreach.property.show}
|
||||
------
|
||||
|
||||
The show `show` property can be used after the execution of a
|
||||
`{foreach}` loop to detect if data has been displayed or not. `show` is
|
||||
a boolean value.
|
||||
|
||||
|
||||
<ul>
|
||||
{foreach $myArray as $name}
|
||||
<li>{$name}</li>
|
||||
{/foreach}
|
||||
</ul>
|
||||
{if $name@show} do something here if the array contained data {/if}
|
||||
|
||||
\@total {#foreach.property.total}
|
||||
-------
|
||||
|
||||
`total` contains the number of iterations that this `{foreach}` will
|
||||
loop. This can be used inside or after the `{foreach}`.
|
||||
|
||||
|
||||
{* show number of rows at end *}
|
||||
{foreach $items as $item}
|

|
||||
====================
|
||||
|
||||
`{if}` statements in Smarty have much the same flexibility as PHP
|
||||
[if](&url.php-manual;if) statements, with a few added features for the
|
||||
template engine. Every `{if}` must be paired with a matching `{/if}`.
|
||||
`{else}` and `{elseif}` are also permitted. All PHP conditionals and
|
||||
functions are recognized, such as *\|\|*, *or*, *&&*, *and*,
|
||||
*is\_array()*, etc.
|
||||
|
||||
If securty is enabled, only PHP functions from `$php_functions` property
|
||||
of the securty policy are allowed. See the
|
||||
[Security](#advanced.features.security) section for details.
|
||||
|
||||
The following is a list of recognized qualifiers, which must be
|
||||
separated from surrounding elements by spaces. Note that items listed in
|
||||
\[brackets\] are optional. PHP equivalents are shown where applicable.

{include} {#language.function.include}
|
||||
=========
|
||||
|
||||
`{include}` tags are used for including other templates in the current
|
||||
template. Any variables available in the current template are also
|
||||
available within the included template.
|
||||
|
||||
- The `{include}` tag must have the `file` attribute which contains
|
||||
the template resource path.
|
||||
|
||||
- Setting the optional `assign` attribute specifies the template
|
||||
variable that the output of `{include}` is assigned to, instead of
|
||||
being displayed. Similar to [`{assign}`](#language.function.assign).
|
||||
|
||||
- Variables can be passed to included templates as
|
||||
[attributes](#language.syntax.attributes). Any variables explicitly
|
||||
passed to an included template are only available within the scope
|
||||
of the included file. Attribute variables override current template
|
||||
variables, in the case when they are named the same.
|
||||
|
||||
- You can use all variables from the including template inside the
|
||||
included template. But changes to variables or new created variables
|
||||
inside the included template have local scope and are not visible
|
||||
inside the including template after the `{include}` statement. This
|
||||
default behaviour can be changed for all variables assigned in the
|
||||
included template by using the scope attribute at the `{include}`
|
||||
statement or for individual variables by using the scope attribute
|
||||
at the [`{assign}`](#language.function.assign) statement. The later
|
||||
is useful to return values from the included template to the
|
||||
including template.
|
||||
|
||||
- Use the syntax for [template resources](#resources) to `{include}`
|
||||
files outside of the [`$template_dir`](#variable.template.dir)
|
||||
directory.

=========

`{literal}` tags allow a block of data to be taken literally. This is
|

typically used around Javascript or stylesheet blocks where {curly

braces} would interfere with the template
|

[delimiter](#variable.left.delimiter) syntax. Anything within
|

`{literal}{/literal}` tags is not interpreted, but displayed as-is. If

you need template tags embedded in a `{literal}` block, consider using

[`{ldelim}{rdelim}`](#language.function.ldelim) to escape the individual

delimiters instead.

nocache Disables caching of the `{section}` loop
|
||||
|
||||
- Required attributes are `name` and `loop`.
|
||||
|
||||
- The `name` of the `{section}` can be anything you like, made up of
|
||||
letters, numbers and underscores, like [PHP
|
||||
variables](&url.php-manual;language.variables).
|
||||
|
||||
- {section}\'s can be nested, and the nested `{section}` names must be
|
||||
unique from each other.
|
||||
|
||||
- The `loop` attribute, usually an array of values, determines the
|
||||
number of times the `{section}` will loop. You can also pass an
|
||||
integer as the loop value.
|
||||
|
||||
- When printing a variable within a `{section}`, the `{section}`
|
||||
`name` must be given next to variable name within \[brackets\].
|
||||
|
||||
- `{sectionelse}` is executed when there are no values in the loop
|
||||
variable.
|
||||
|
||||
- A `{section}` also has its own variables that handle `{section}`
|
||||
properties. These properties are accessible as:
|
||||
[`{$smarty.section.name.property}`](#language.variables.smarty.loops)
|
||||
where "name" is the attribute `name`.
|
||||
|
||||
- `{section}` properties are [`index`](#section.property.index),
|
||||
[`index_prev`](#section.property.index.prev),
|
||||
[`index_next`](#section.property.index.next),
|
||||
[`iteration`](#section.property.iteration),

The `name` of the `{section}` can be anything you like, see [PHP
|
||||
variables](&url.php-manual;language.variables). It is used to reference
|
||||
the data within the `{section}`.
|
||||
|
||||
|
||||
{section name=anything loop=$myArray}
|
||||
{$myArray[anything].foo}
|
||||
{$name[anything]}
|
||||
{$address[anything].bar}
|
||||
{/section}
|
||||
|
||||
|
||||
|
||||
This is an example of printing an associative array of data with a
|
||||
`{section}`. Following is the php script to assign the `$contacts` array
|
||||
to Smarty.
|
||||
|
||||
|
||||
<?php
|
||||
$data = array(
|
||||
array('name' => 'John Smith', 'home' => '555-555-5555',
|
||||
'cell' => '666-555-5555', 'email' => 'john@myexample.com'),
|
||||
array('name' => 'Jack Jones', 'home' => '777-555-5555',
|
||||
'cell' => '888-555-5555', 'email' => 'jack@myexample.com'),
|
||||
array('name' => 'Jane Munson', 'home' => '000-555-5555',
|
||||
'cell' => '123456', 'email' => 'jane@myexample.com')
|
||||
);
|
||||
$smarty->assign('contacts',$data);
|
||||
?>
|
||||
|
||||
|
||||
|
||||
The template to output `$contacts`
|
||||
|
||||
|
||||
{section name=customer loop=$contacts}
|
||||
<p>
|
||||
name: {$contacts[customer].name}<br />
|
||||
home: {$contacts[customer].home}<br />
|
||||
cell: {$contacts[customer].cell}<br />
|
||||
e-mail: {$contacts[customer].email}
|
||||
</p>
|
||||
{/section}
|
||||
|
||||
|
||||
|
||||
The above example will output:
|
||||
|
||||
|
||||
<p>
|
||||
name: John Smith<br />
|
||||
home: 555-555-5555<br />
|
||||
cell: 666-555-5555<br />
|
||||
e-mail: john@myexample.com
|
||||
</p>
|
||||
<p>
|
||||
name: Jack Jones<br />
|
||||
home phone: 777-555-5555<br />
|
||||
cell phone: 888-555-5555<br />
|
||||
e-mail: jack@myexample.com
|
||||
</p>
|
||||
<p>
|
||||
name: Jane Munson<br />
|
||||
home phone: 000-555-5555<br />
|
||||
cell phone: 123456<br />
|
||||
e-mail: jane@myexample.com
|
||||
</p>
|
||||
|
||||
|
||||
|
||||
This example assumes that `$custid`, `$name` and `$address` are all
|
||||
arrays containing the same number of values. First the php script that
|
||||
assign\'s the arrays to Smarty.
|
||||
|
||||
|
||||
<?php
|
||||
|
||||
$id = array(1001,1002,1003);
|
||||
$smarty->assign('custid',$id);
|
||||
|
||||
$fullnames = array('John Smith','Jack Jones','Jane Munson');
|
||||
$smarty->assign('name',$fullnames);
|
||||
|
||||
$addr = array('253 Abbey road', '417 Mulberry ln', '5605 apple st');
|
||||
$smarty->assign('address',$addr);
|
||||
|
||||
?>
|
||||
|
||||
The `loop` variable only determines the number of times to loop. You can
|
||||
access ANY variable from the template within the `{section}`. This is
|
||||
useful for looping multiple arrays. You can pass an array which will
|
||||
determine the loop count by the array size, or you can pass an integer
|
||||
to specify the number of loops.
|
||||
|
||||
|
||||
{section name=customer loop=$custid}
|
||||
<p>
|
||||
id: {$custid[customer]}<br />
|
||||
name: {$name[customer]}<br />
|
||||
address: {$address[customer]}
|
||||
</p>
|
||||
{/section}
|
||||
|
||||
|
||||
|
||||
The above example will output:
|
||||
|
||||
|
||||
<p>
|
||||
id: 1000<br />
|
||||
name: John Smith<br />
|
||||
address: 253 Abbey road
|
||||
</p>
|
||||
<p>
|
||||
id: 1001<br />
|
||||
name: Jack Jones<br />
|
||||
address: 417 Mulberry ln
|
||||
</p>
|
||||
<p>
|
||||
id: 1002<br />
|
||||
name: Jane Munson<br />
|
||||
address: 5605 apple st
|
||||
</p>
|
||||
|
||||
|
||||
|
||||
{section}\'s can be nested as deep as you like. With nested
|
||||
{section}\'s, you can access complex data structures, such as
|
||||
multi-dimensional arrays. This is an example `.php` script that
|
||||
assigns the arrays.
|
||||
|
||||
|
||||
<?php
|
||||
|
||||
$id = array(1001,1002,1003);
|
||||
$smarty->assign('custid',$id);
|
||||
|
||||
$fullnames = array('John Smith','Jack Jones','Jane Munson');
|
||||
$smarty->assign('name',$fullnames);
|
||||
|
||||
$addr = array('253 N 45th', '417 Mulberry ln', '5605 apple st');
|
||||
$smarty->assign('address',$addr);
|
||||
|
||||
$types = array(
|
||||
array( 'home phone', 'cell phone', 'e-mail'),
|
||||
array( 'home phone', 'web'),
|
||||
array( 'cell phone')
|
||||
);
|
||||
$smarty->assign('contact_type', $types);
|
||||
|
||||
$info = array(
|
||||
array('555-555-5555', '666-555-5555', 'john@myexample.com'),
|
||||
array( '123-456-4', 'www.example.com'),
|
||||
array( '0457878')
|
||||
);
|
||||
$smarty->assign('contact_info', $info);
|
||||
|
||||
?>
|
||||
|
||||
|
||||
In this template, *\$contact\_type\[customer\]* is an array of contact
|
||||
types for the current customer.
|
||||
|
||||
|
||||
{section name=customer loop=$custid}

</table>
|
||||
|

.index {#section.property.index}
|
||||
------
|
||||
|
||||
`index` contains the current array index, starting with zero or the
|
||||
`start` attribute if given. It increments by one or by the `step`
|
||||
attribute if given.
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> If the `step` and `start` properties are not modified, then this works
|

|
||||
|
||||
|
||||
.index\_prev {#section.property.index.prev}
|
||||
------------
|
||||
|
||||
`index_prev` is the previous loop index. On the first loop, this is set
|
||||
to -1.
|
||||
|
||||
.index\_next {#section.property.index.next}
|
||||
------------
|
||||
|
||||
`index_next` is the next loop index. On the last loop, this is still one
|
||||
more than the current index, respecting the setting of the `step`
|
||||
attribute, if given.

|
||||
|
||||
|
||||
|

.iteration {#section.property.iteration}
|
||||
----------
|
||||
|
||||
`iteration` contains the current loop iteration and starts at one.
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> This is not affected by the `{section}` properties `start`, `step` and

|
||||
> `iteration` also starts with one instead of zero unlike `index`.
|

> [`rownum`](#section.property.rownum) is an alias to `iteration`, they
|
||||
> are identical.
|
||||
|

<?php
|

|
||||
iteration=6 index=15 id=3015<br />
|
||||
|
||||
|
||||
|
||||
Another example that uses the `iteration` property to output a table
|
||||
header block every five rows.
|
||||
|
||||
|
||||
<table>
|
||||
{section name=co loop=$contacts}
|
||||
{if $smarty.section.co.iteration is div by 5}
|
||||
<tr><th> </th><th>Name></th><th>Home</th><th>Cell</th><th>Email</th></tr>
|
||||
{/if}
|
||||
<tr>
|
||||
<td><a href="view.php?id={$contacts[co].id}">view<a></td>
|
||||
<td>{$contacts[co].name}</td>
|
||||
<td>{$contacts[co].home}</td>
|
||||
<td>{$contacts[co].cell}</td>
|
||||
<td>{$contacts[co].email}</td>
|
||||
<tr>
|
||||
{/section}
|
||||
</table>
|
||||
|
||||
|
||||
|
||||
An that uses the `iteration` property to alternate a text color every
|
||||
third row.
|
||||
|
||||
|
||||
<table>
|
||||
{section name=co loop=$contacts}
|
||||
{if $smarty.section.co.iteration is even by 3}
|
||||
<span style="color: #ffffff">{$contacts[co].name}</span>
|
||||
{else}
|
||||
<span style="color: #dddddd">{$contacts[co].name}</span>
|
||||
{/if}
|
||||
{/section}
|
||||
</table>
|
||||
|
||||
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> The *\"is div by\"* syntax is a simpler alternative to the PHP mod
|
||||
> operator syntax. The mod operator is allowed:
|
||||
> `{if $smarty.section.co.iteration % 5 == 1}` will work just the same.
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> You can also use *\"is odd by\"* to reverse the alternating.
|
||||
|
||||
.first {#section.property.first}
|
||||
------
|
||||
|
||||
`first` is set to TRUE if the current `{section}` iteration is the
|
||||
initial one.
|
||||
|
||||
.last {#section.property.last}
|
||||
-----
|
||||
|
||||
`last` is set to TRUE if the current section iteration is the final one.
|
||||
|
||||
This example loops the `$customers` array, outputs a header block on the
|
||||
first iteration and on the last outputs the footer block. Also uses the
|
||||
[`total`](#section.property.total) property.
|
||||
|
||||
|
||||
{section name=customer loop=$customers}
|
||||
{if $smarty.section.customer.first}
|
||||
<table>
|
||||
<tr><th>id</th><th>customer</th></tr>
|
||||
{/if}
|
||||
|
||||
<tr>
|
||||
<td>{$customers[customer].id}}</td>
|
||||
<td>{$customers[customer].name}</td>
|
||||
</tr>
|
||||
|
||||
{if $smarty.section.customer.last}
|
||||
<tr><td></td><td>{$smarty.section.customer.total} customers</td></tr>
|
||||
</table>
|
||||
{/if}
|
||||
{/section}
|
||||
|
||||
|
||||
|
||||
.rownum {#section.property.rownum}
|
||||
-------
|
||||
|
||||
`rownum` contains the current loop iteration, starting with one. It is
|
||||
an alias to [`iteration`](#section.property.iteration), they work
|
||||
identically.
|
||||
|
||||
.loop {#section.property.loop}
|
||||
-----
|
||||
|
||||
`loop` contains the last index number that this {section} looped. This
|
||||
can be used inside or after the `{section}`.
|
||||
|
||||
|
||||
{section name=customer loop=$custid}
|
||||
{$smarty.section.customer.index} id: {$custid[customer]}<br />
|
||||
{/section}
|
||||
There are {$smarty.section.customer.loop} customers shown above.
|
||||
|
||||
|
||||
|
||||
The above example will output:
|
||||
|
||||
|
||||
0 id: 1000<br />
|
||||
1 id: 1001<br />
|
||||
2 id: 1002<br />
|
||||
There are 3 customers shown above.
|
||||
|
||||
|
||||
|
||||
.show {#section.property.show}
|
||||
-----
|
||||
|
||||
`show` is used as a parameter to section and is a boolean value. If
|
||||
FALSE, the section will not be displayed. If there is a `{sectionelse}`
|
||||
present, that will be alternately displayed.
|
||||
|
||||
Boolean `$show_customer_info` has been passed from the PHP application,
|
||||
to regulate whether or not this section shows.
|
||||
|

This is a short-hand version of the {assign} function. You can assign
|
||||
values directly to the template, or assign values to array elements too.
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> Assignment of variables in-template is essentially placing application
|

{while} {#language.function.while}
|

=======
|

|

`{while}` loops in Smarty have much the same flexibility as PHP
|
||||
[while](&url.php-manual;while) statements, with a few added features for
|
||||
the template engine. Every `{while}` must be paired with a matching
|
||||
`{/while}`. All PHP conditionals and functions are recognized, such as
|
||||
*\|\|*, *or*, *&&*, *and*, *is\_array()*, etc.
|
||||
|
||||
The following is a list of recognized qualifiers, which must be
|
||||
separated from surrounding elements by spaces. Note that items listed in
|
||||
\[brackets\] are optional. PHP equivalents are shown where applicable.

{counter} {#language.function.counter}
|

=========
|

|

`{counter}` is used to print out a count. `{counter}` will remember the
|
||||
count on each iteration. You can adjust the number, the interval and the
|
||||
direction of the count, as well as determine whether or not to print the
|
||||
value. You can run multiple counters concurrently by supplying a unique
|
||||
name for each one. If you do not supply a name, the name "default" will
|
||||
be used.
|
||||
|
||||
If you supply the `assign` attribute, the output of the `{counter}`
|

{cycle} {#language.function.cycle}
|
||||
=======
|
||||
|

`{cycle}` is used to alternate a set of values. This makes it easy to
|
||||
for example, alternate between two or more colors in a table, or cycle
|
||||
through an array of values.
|
||||
|
||||
Attribute Name Type Required Default Description

---------------- --------- ---------- ----------- -------------------------------------------------------------------------------------------------------------

|
||||

|

assign string No *n/a* The template variable the output will be assigned to
|
||||
reset boolean No *FALSE* The cycle will be set to the first value and not advanced
|
||||
|
||||
- You can `{cycle}` through more than one set of values in a template
|
||||
by supplying a `name` attribute. Give each `{cycle}` an unique
|
||||
`name`.
|
||||
|
||||
- You can force the current value not to print with the `print`
|
||||
attribute set to FALSE. This would be useful for silently skipping a
|
||||
value.
|
||||
|
||||
- The `advance` attribute is used to repeat a value. When set to
|
||||
FALSE, the next call to `{cycle}` will print the same value.
|
||||
|
||||
- If you supply the `assign` attribute, the output of the `{cycle}`
|
||||
function will be assigned to a template variable instead of being

=============
|
||||
|
||||
`{html_image}` is a [custom function](#language.custom.functions) that
|
||||
generates an HTML `<img>` tag. The `height` and `width` are
|
||||
automatically calculated from the image file if they are not supplied.
|
||||
|
||||
Attribute Name Type Required Default Description
|
||||
---------------- -------- ---------- ----------------------- ---------------------------------------
|
||||
file string Yes *n/a* name/path to image
|
||||
height string No *actual image height* Height to display image
|
||||
width string No *actual image width* Width to display image
|
||||
basedir string no *web server doc root* Directory to base relative paths from
|
||||
alt string no *""* Alternative description of the image
|
||||
href string no *n/a* href value to link the image to
|
||||
path\_prefix string no *n/a* Prefix for output path
|
||||
|
||||
- `basedir` is the base directory that relative image paths are based
|
||||
from. If not given, the web server\'s document root
|
||||
`$_ENV['DOCUMENT_ROOT']` is used as the base. If security is
|
||||
enabled, then the image must be located in the `$secure_dir` path of
|
||||
the security policy. See the [Security](#advanced.features.security)
|
||||
section for details.
|
||||
|
||||
- `href` is the href value to link the image to. If link is supplied,
|
||||
an `<a href="LINKVALUE"><a>` tag is placed around the image tag.
|
||||
|
||||
- `path_prefix` is an optional prefix string you can give the output
|
||||
path. This is useful if you want to supply a different server name
|
||||
for the image.
|
||||
|
||||
- All parameters that are not in the list above are printed as
|
||||
name/value-pairs inside the created `<img>` tag.
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> `{html_image}` requires a hit to the disk to read the image and
|
||||
> calculate the height and width. If you don\'t use template
|
||||

`{html_options}` is a [custom function](#language.custom.functions) that

strict boolean No *FALSE* Will make the \"extra\" attributes *disabled* and *readonly* only be set, if they were supplied with either boolean *TRUE* or string *\"disabled\"* and *\"readonly\"* respectively
|
||||
|
||||
- Required attributes are `values` and `output`, unless you use the
|
||||
combined `options` instead.
|
||||
|
||||
- If the optional `name` attribute is given, the `<select></select>`
|
||||
tags are created, otherwise ONLY the `<option>` list is generated.
|
||||
|
||||
- If a given value is an array, it will treat it as an html
|
||||
`<optgroup>`, and display the groups. Recursion is supported with
|
||||
`<optgroup>`.
|
||||
|
||||
- All parameters that are not in the list above are printed as
|
||||
name/value-pairs inside the `<select>` tag. They are ignored if the
|
||||
optional `name` is not given.

|
||||
cols mixed No *3* Number of columns in the table or a comma-separated list of column heading names or an array of column heading names.if the cols-attribute is empty, but rows are given, then the number of cols is computed by the number of rows and the number of elements to display to be just enough cols to display all elements. If both, rows and cols, are omitted cols defaults to 3. if given as a list or array, the number of columns is computed from the number of elements in the list or array.
|
||||

- The `table_attr`, `tr_attr` and `td_attr` values determine the
|
||||
attributes given to the `<table>`, `<tr>` and `<td>` tags.
|
||||
|
||||
- If `tr_attr` or `td_attr` are arrays, they will be cycled through.
|
||||
|
||||
- `trailpad` is the value put into the trailing cells on the last
|
||||
table row if there are any present.

{math} {#language.function.math}
|

======
|
||||
|

`{math}` allows the template designer to do math equations in the
|
||||
template.
|
||||
|
||||
- Any numeric template variables may be used in the equations, and the
|
||||
result is printed in place of the tag.
|
||||
|
||||
- The variables used in the equation are passed as parameters, which
|
||||
can be template variables or static values.
|
||||
|
||||
- +, -, /, \*, abs, ceil, cos, exp, floor, log, log10, max, min, pi,
|
||||
pow, rand, round, sin, sqrt, srans and tan are all valid operators.
|
||||
Check the PHP documentation for further information on these
|
||||
[math](&url.php-manual;eval) functions.
|
||||
|
||||
- If you supply the `assign` attribute, the output of the `{math}`
|
||||
function will be assigned to this template variable instead of being
|
||||
output to the template.
|
||||
|
||||

|

Variable modifiers can be applied to
|
||||
[variables](./language-variables.md), [custom
|
||||
functions](./language-custom-functions.md) or strings. To apply a modifier,
|
||||
specify the value followed by a `|` (pipe) and the modifier name. A
|
||||
modifier may accept additional parameters that affect its behavior.
|
||||
These parameters follow the modifier name and are separated by a `:`
|
||||
(colon). Also, *all php-functions can be used as modifiers implicitly*
|
||||
(more below) and modifiers can be
|
||||
[combined](./language-combining-modifiers.md).

||||

|

|
||||
|
||||
|
||||
- Modifiers can be applied to any type of variables, including arrays
|
||||
and objects.
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> The default behavior was changed with Smarty 3. In Smarty 2.x, you
|
||||
> had to use an \"`@`\" symbol to apply a modifier to an array, such
|
||||
> as `{$articleTitle|@count}`. With Smarty 3, the \"`@`\" is no
|
||||
> longer necessary, and is ignored.
|
||||
>
|
||||
> If you want a modifier to apply to each individual item of an
|
||||
> array, you will either need to loop the array in the template, or
|
||||
> provide for this functionality inside your modifier function.
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> Second, in Smarty 2.x, modifiers were applied to the result of
|
||||
> math expressions like `{8+2}`, meaning that
|
||||
> `{8+2|count_characters}` would give `2`, as 8+2=10 and 10 is two
|
||||
> characters long. With Smarty 3, modifiers are applied to the
|
||||
> variables or atomic expressions before executing the calculations,
|
||||
> so since 2 is one character long, `{8+2|count_characters}`
|
||||
> gives 9. To get the old result use parentheses like
|
||||
> `{(8+2)|count_characters}`.
|
||||
|
||||
- Modifiers are autoloaded from the
|
||||
[`$plugins_dir`](../programmers/api-variables/variable-plugins-dir.md) or can be registered
|
||||
explicitly with the [`registerPlugin()`](../programmers/api-functions/api-register-plugin.md)
|
||||
function. The later is useful for sharing a function between php
|
||||
scripts and smarty templates.
|
||||
|
||||
- All php-functions can be used as modifiers implicitly, as
|
||||
demonstrated in the example above. However, using php-functions as
|
||||
modifiers has two little pitfalls:
|
||||
|
||||
- First - sometimes the order of the function-parameters is not
|
||||
the desirable one. Formatting `$foo` with
|
||||
`{"%2.f"|sprintf:$foo}` actually works, but asks for the more
|
||||
intuitive, like `{$foo|string_format:"%2.f"}` that is provided
|
||||
by the Smarty distribution.
|
||||
|
||||
- Secondly - if security is enabled, all php-functions that are to
|
||||
be used as modifiers have to be declared trusted in the
|
||||
`$modifiers` property of the security policy. See the
|
||||
[Security](../programmers/advanced-features/advanced-features-security.md) section for details.

||||

||||

This formats a date and time into the given

Smarty as unix [timestamps](&url.php-manual;function.time), [DateTime

objects](&url.php-manual;class.DateTime), mysql timestamps or any string
|

made up of month day year, parsable by php\'s

[`strtotime()`](&url.php-manual;strtotime). Designers can then use
|
||||
`date_format` to have complete control of the formatting of the date. If

the date passed to `date_format` is empty and a second parameter is
|
||||
passed, that will be used as the date to format.

display at the end if the variable was truncated. The characters in the
|
||||
string are included with the original truncation length. By default,

`truncate` will attempt to cut off at a word boundary. If you want to

of TRUE.

|

Smarty has several different types of variables. The type of the
|
||||
variable depends on what symbol it is prefixed or enclosed within.
|
||||
|
||||
Variables in Smarty can be either displayed directly or used as
|
||||
arguments for [functions](./language-basic-syntax/language-syntax-functions.md),
|
||||
[attributes](./language-basic-syntax/language-syntax-attributes.md) and
|
||||
[modifiers](./language-modifiers.md), inside conditional expressions, etc.
|
||||
To print a variable, simply enclose it in the
|
||||
[delimiters](../programmers/api-variables/variable-left-delimiter.md) so that it is the only thing
|
||||
contained between them.

|
||||
|
||||
|
||||

Associative arrays {#language.variables.assoc.arrays}
|
||||
------------------
|
||||
|
||||
You can also reference associative array variables by specifying the key
|
||||
after a dot \".\" symbol.
|
||||

||||
|
||||

|
||||
|
||||
|
||||
Array indexes {#language.variables.array.indexes}
|
||||
-------------
|
||||
|
||||
You can reference arrays by their index, much like native PHP syntax.
|
||||
|
||||
|
||||
<?php
|
||||

|
||||
'555-222-9876',

|
||||

|
||||
`index.tpl` source:
|

|
||||
|
||||
{$Contacts[0]}<br />
|
||||
{$Contacts[1]}<br />
|
||||
{* you can print arrays of arrays as well *}
|
||||
{$Contacts[2][0]}<br />
|
||||
{$Contacts[2][1]}<br />
|
||||
|
||||
|
||||
|
||||
This will output:

Variables loaded from config files {#language.config.variables}
|
||||
==================================
|
||||
|
||||
Variables that are loaded from the [config files](#config.files) are
|
||||
referenced by enclosing them within `#hash_marks#`, or with the smarty
|
||||
variable [`$smarty.config`](#language.variables.smarty.config). The
|
||||
later syntax is useful for embedding into quoted attribute values, or
|
||||
accessing variable values such as \$smarty.config.\$foo.
|
||||
|
||||
Example config file - `foo.conf`:
|
||||
|
||||
|
||||
pageTitle = "This is mine"
|
||||
bodyBgColor = '#eeeeee'
|
||||
tableBorderSize = 3
|

tableBgColor = "#bbbbbb"
|
||||
rowBgColor = "#cccccc"

Variable scopes {#language.variable.scopes}
|
||||
===============
|
||||
|
||||
You have the choice to assign variables to the scope of the main Smarty
|
||||
object, data objects created with [`createData()`](#api.create.data),
|
||||
and template objects created with
|
||||
[`createTemplate()`](#api.create.template). These objects can be
|
||||
chained. A template sees all the variables of its own object and all
|
||||
variables assigned to the objects in its chain of parent objects.
|
||||
|
||||
By default templates which are rendered by
|
||||
[`$smarty->display(...)`](#api.display) or
|
||||
[`$smarty->fetch(...)`](#api.fetch) calls are automatically linked to
|
||||
the Smarty object variable scope.
|
||||
|
||||
By assigning variables to individual data or template objects you have
|
||||
full control which variables can be seen by a template.
|
||||
|
||||
|
||||
|
||||
// assign variable to Smarty object scope
|
||||
$smarty->assign('foo','smarty');
|
||||
|

$data->assign('bar','bar-data');

$data2 = $smarty->createData($data);
|
||||
$data2->assign('bar','bar-data2');

{\$smarty} reserved variable {#language.variables.smarty}
|
||||
============================
|
||||
|
||||
The PHP reserved `{$smarty}` variable can be used to access several
|
||||
environment and request variables. The full list of them follows.
|
||||
|
||||
Request variables {#language.variables.smarty.request}
|
||||
-----------------
|
||||
|
||||
The [request variables](&url.php-manual;reserved.variables) such as
|
||||
`$_GET`, `$_POST`, `$_COOKIE`, `$_SERVER`, `$_ENV` and `$_SESSION` can
|
||||
be accessed as demonstrated in the examples below:
|
||||
|
||||
|
||||
{* display value of page from URL ($_GET) http://www.example.com/index.php?page=foo *}
|
||||
{$smarty.get.page}
|
||||
|
||||
{* display the variable "page" from a form ($_POST['page']) *}
|
||||
{$smarty.post.page}
|
||||
|
||||
{* display the value of the cookie "username" ($_COOKIE['username']) *}
|
||||
{$smarty.cookies.username}
|
||||
|
||||
{* display the server variable "SERVER_NAME" ($_SERVER['SERVER_NAME'])*}
|
||||
{$smarty.server.SERVER_NAME}
|
||||
|
||||
{* display the system environment variable "PATH" *}
|
||||
{$smarty.env.PATH}
|
||||
|
||||
{* display the php session variable "id" ($_SESSION['id']) *}
|
||||
{$smarty.session.id}
|
||||
|
||||
{* display the variable "username" from merged get/post/cookies/server/env *}
|
||||
{$smarty.request.username}
|
||||
|
||||
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> For historical reasons `{$SCRIPT_NAME}` is short-hand for
|
||||
> `{$smarty.server.SCRIPT_NAME}`.
|
||||
>
|
||||
>
|
||||
> <a href="{$SCRIPT_NAME}?page=smarty">click me</a>
|
||||
> <a href="{$smarty.server.SCRIPT_NAME}?page=smarty">click me</a>
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> Although Smarty provides direct access to PHP super globals for
|
||||
> convenience, it should be used with caution. Directly accessing super
|
||||
> globals mixes underlying application code structure with templates. A
|
||||

|
||||
|
||||
{\$smarty.now} {#language.variables.smarty.now}
|
||||
--------------
|
||||
|
||||
The current [timestamp](&url.php-manual;function.time) can be accessed
|
||||
with `{$smarty.now}`. The value reflects the number of seconds passed
|
||||
since the so-called Epoch on January 1, 1970, and can be passed directly
|
||||
to the [`date_format`](#language.modifier.date.format) modifier for
|
||||
display. Note that [`time()`](&url.php-manual;function.time) is called
|
||||
on each invocation; eg a script that takes three seconds to execute with
|
||||
a call to `$smarty.now` at start and end will show the three second
|
||||
difference.
|
||||
|
||||
::: {.informalexample}
|
||||
|
||||
{* use the date_format modifier to show current date and time *}
|
||||
{$smarty.now|date_format:'%Y-%m-%d %H:%M:%S'}
|
||||
|
||||
|
||||
:::
|
||||
|
||||
{\$smarty.const} {#language.variables.smarty.const}
|
||||
----------------
|
||||
|
||||
You can access PHP constant values directly. See also [smarty
|
||||
constants](#smarty.constants).
|
||||
|
||||
::: {.informalexample}
|
||||
|
||||
<?php
|
||||
// the constant defined in php
|
||||
define('MY_CONST_VAL','CHERRIES');
|
||||
?>
|
||||
:::
|
||||
|
||||
Output the constant in a template with
|
||||
|
||||
::: {.informalexample}
|
||||
|
||||
{$smarty.const.MY_CONST_VAL}
|
||||
:::
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> Although Smarty provides direct access to PHP constants for
|
||||

|
||||

|
||||

|
||||
|
||||
{\$smarty.capture} {#language.variables.smarty.capture}
|
||||
------------------
|
||||
|
||||
Template output captured via the built-in
|
||||
[`{capture}..{/capture}`](#language.function.capture) function can be
|
||||
accessed using the `{$smarty.capture}` variable. See the
|
||||
[`{capture}`](#language.function.capture) page for more information.
|
||||
|
||||
{\$smarty.config} {#language.variables.smarty.config}
|
||||
-----------------
|
||||
|
||||
`{$smarty.config}` variable can be used to refer to loaded [config
|
||||
variables](#language.config.variables). `{$smarty.config.foo}` is a
|
||||
synonym for `{#foo#}`. See the
|
||||
[{config\_load}](#language.function.config.load) page for more info.
|
||||
|
||||
{\$smarty.section} {#language.variables.smarty.loops}
|
||||
------------------
|
||||
|
||||
The `{$smarty.section}` variables can be used to refer to
|
||||
[`{section}`](#language.function.section) loop properties. These have
|
||||
some very useful values such as `.first`, `.index`, etc.
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> The `{$smarty.foreach}` variable is no longer used with the new
|
||||
> [`{foreach}`](#language.function.foreach) syntax, but is still
|
||||
> supported with Smarty 2.x style foreach syntax.
|
||||
|
||||
{\$smarty.template} {#language.variables.smarty.template}
|
||||
-------------------
|
||||
|
||||
Returns the name of the current template being processed (without the
|
||||
directory).
|
||||
|
||||
{\$smarty.template\_object} {#language.variables.smarty.template_object}
|
||||
---------------------------
|
||||
|
||||
Returns the template object of the current template being processed.
|
||||
|
||||
{\$smarty.current\_dir} {#language.variables.smarty.current_dir}
|
||||
-----------------------
|
||||
|
||||
Returns the name of the directory for the current template being
|
||||
processed.
|
||||
|
||||
{\$smarty.version} {#language.variables.smarty.version}
|
||||
------------------
|
||||
|
||||
Returns the version of Smarty the template was compiled with.
|
||||
|
||||
|
||||
<div id="footer">Powered by Smarty {$smarty.version}</div>
|
||||
|
||||
{\$smarty.block.child} {#language.variables.smarty.block.child}
|
||||
----------------------
|
||||
|
||||
Returns block text from child template. See [Template
|
||||
inheritance](#advanced.features.template.inheritance).
|
||||
|
||||
{\$smarty.block.parent} {#language.variables.smarty.block.parent}
|
||||
-----------------------
|
||||
|
||||
Returns block text from parent template. See [Template
|
||||
inheritance](#advanced.features.template.inheritance)
|
||||
|
||||
{\$smarty.ldelim}, {\$smarty.rdelim} {#language.variables.smarty.ldelim}
|
||||
------------------------------------
|
||||
|
||||
These variables are used for printing the left-delimiter and
|
||||
right-delimiter value literally, the same as
|
||||
[`{ldelim},{rdelim}`](#language.function.ldelim).

# Tips & Tricks
|
||||
|
||||
## Blank Variable Handling
|
||||
|
||||
There may be times when you want to print a default value for an empty
|
||||
variable instead of printing nothing, such as printing ` ` so that
|
||||
html table backgrounds work properly. Many would use an
|
||||
[`{if}`](../designers/language-builtin-functions/language-function-if.md) statement to handle this, but there is a
|
||||
shorthand way with Smarty, using the
|
||||
[`default`](../designers/language-modifiers/language-modifier-default.md) variable modifier.
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> "Undefined variable" errors will show an E\_NOTICE if not disabled in
|
||||
> PHP's [`error_reporting()`](https://www.php.net/error_reporting) level or
|
||||
> Smarty's [`$error_reporting`](../programmers/api-variables/variable-error-reporting.md) property and
|
||||
> a variable had not been assigned to Smarty.
|
||||
|
||||
```smarty
|
||||
|
||||
{* the long way *}
|
||||
{if $title eq ''}
|
||||
|
||||
{else}
|
||||
{$title}
|
||||
{/if}
|
||||
|
||||
{* the short way *}
|
||||
{$title|default:' '}
|
||||
|
||||
```
|
||||
|
||||
See also [`default`](../designers/language-modifiers/language-modifier-default.md) modifier and [default
|
||||
variable handling](#default-variable-handling).
|
||||
|
||||
## Default Variable Handling
|
||||
|
||||
If a variable is used frequently throughout your templates, applying the
|
||||
[`default`](../designers/language-modifiers/language-modifier-default.md) modifier every time it is
|
||||
mentioned can get a bit ugly. You can remedy this by assigning the
|
||||
variable its default value with the
|
||||
[`{assign}`](../designers/language-builtin-functions/language-function-assign.md) function.
|
||||
|
||||
|
||||
{* do this somewhere at the top of your template *}
|
||||
{assign var='title' value=$title|default:'no title'}
|
||||
|
||||
{* if $title was empty, it now contains the value "no title" when you use it *}
|
||||
{$title}
|
||||
|
||||
|
||||
|
||||
See also [`default`](../designers/language-modifiers/language-modifier-default.md) modifier and [blank
|
||||
variable handling](#blank-variable-handling).
|
||||
|
||||
## Passing variable title to header template
|
||||
|
||||
When the majority of your templates use the same headers and footers, it
|
||||
is common to split those out into their own templates and
|
||||
[`{include}`](../designers/language-builtin-functions/language-function-include.md) them. But what if the header
|
||||
needs to have a different title, depending on what page you are coming
|
||||
from? You can pass the title to the header as an
|
||||
[attribute](../designers/language-basic-syntax/language-syntax-attributes.md) when it is included.
|
||||
|
||||
`mainpage.tpl` - When the main page is drawn, the title of "Main Page"
|
||||
is passed to the `header.tpl`, and will subsequently be used as the
|
||||
title.
|
||||
|
||||
```smarty
|
||||
|
||||
{include file='header.tpl' title='Main Page'}
|
||||
{* template body goes here *}
|
||||
{include file='footer.tpl'}
|
||||
|
||||
```
|
||||
|
||||
`archives.tpl` - When the archives page is drawn, the title will be
|
||||
"Archives". Notice in the archive example, we are using a variable from
|
||||
the `archives_page.conf` file instead of a hard coded variable.
|
||||
|
||||
```smarty
|
||||
|
||||
{config_load file='archive_page.conf'}
|
||||
|
||||
{include file='header.tpl' title=#archivePageTitle#}
|
||||
{* template body goes here *}
|
||||
{include file='footer.tpl'}
|
||||
|
||||
```
|
||||
|
||||
|
||||
`header.tpl` - Notice that "Smarty News" is printed if the `$title`
|
||||
variable is not set, using the [`default`](../designers/language-modifiers/language-modifier-default.md)
|
||||
variable modifier.
|
||||
|
||||
```smarty
|
||||
|
||||
<html>
|
||||
<head>
|
||||
<title>{$title|default:'Smarty News'}</title>
|
||||
</head>
|
||||
<body>
|
||||
|
||||
```
|
||||
|
||||
|
||||
`footer.tpl`
|
||||
|
||||
```smarty
|
||||
|
||||
</body>
|
||||
</html>
|
||||
|
||||
```
|
||||
|
||||
|
||||
## Dates
|
||||
|
||||
As a rule of thumb, always pass dates to Smarty as
|
||||
[timestamps](https://www.php.net/time). This allows template designers to
|
||||
use the [`date_format`](../designers/language-modifiers/language-modifier-date-format.md) modifier for
|
||||
full control over date formatting, and also makes it easy to compare
|
||||
dates if necessary.
|
||||
|
||||
```smarty
|
||||
{$startDate|date_format}
|
||||
```
|
||||
|
||||
|
||||
This will output:
|
||||
|
||||
```
|
||||
Jan 4, 2009
|
||||
```
|
||||
|
||||
```smarty
|
||||
|
||||
{$startDate|date_format:"%Y/%m/%d"}
|
||||
|
||||
```
|
||||
|
||||
|
||||
This will output:
|
||||
|
||||
```
|
||||
2009/01/04
|
||||
```
|
||||
|
||||
Dates can be compared in the template by timestamps with:
|
||||
|
||||
```smarty
|
||||
|
||||
{if $order_date < $invoice_date}
|
||||
...do something..
|
||||
{/if}
|
||||
|
||||
```
|
||||
|
||||
When using [`{html_select_date}`](../designers/language-custom-functions/language-function-html-select-date.md)
|
||||
in a template, the programmer will most likely want to convert the
|
||||
output from the form back into timestamp format. Here is a function to
|
||||
help you with that.
|
||||
|
||||
```php
|
||||
|
||||
<?php
|
||||
|
||||
// this assumes your form elements are named
|
||||
// startDate_Day, startDate_Month, startDate_Year
|
||||
|
||||
$startDate = makeTimeStamp($startDate_Year, $startDate_Month, $startDate_Day);
|
||||
|
||||
function makeTimeStamp($year='', $month='', $day='')
|
||||
{
|
||||
if(empty($year)) {
|
||||
$year = strftime('%Y');
|
||||
}
|
||||
if(empty($month)) {
|
||||
$month = strftime('%m');
|
||||
}
|
||||
if(empty($day)) {
|
||||
$day = strftime('%d');
|
||||
}
|
||||
|
||||
return mktime(0, 0, 0, $month, $day, $year);
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
|
||||
See also [`{html_select_date}`](../designers/language-custom-functions/language-function-html-select-date.md),
|
||||
[`{html_select_time}`](../designers/language-custom-functions/language-function-html-select-time.md),
|
||||
[`date_format`](../designers/language-modifiers/language-modifier-date-format.md) and
|
||||
[`$smarty.now`](../designers/language-variables/language-variables-smarty.md#smarty-now),
|
||||
|
||||
## Componentized Templates
|
||||
|
||||
Traditionally, programming templates into your applications goes as
|
||||
follows: First, you accumulate your variables within your PHP
|
||||
application, (maybe with database queries.) Then, you instantiate your
|
||||
Smarty object, [`assign()`](../programmers/api-functions/api-assign.md) the variables and
|
||||
[`display()`](../programmers/api-functions/api-display.md) the template. So lets say for example we
|
||||
have a stock ticker on our template. We would collect the stock data in
|
||||
our application, then assign these variables in the template and display
|
||||
it. Now wouldn't it be nice if you could add this stock ticker to any
|
||||
application by merely including the template, and not worry about
|
||||
fetching the data up front?
|
||||
|
||||
You can do this by writing a custom plugin for fetching the content and
|
||||
assigning it to a template variable.
|
||||
|
||||
`function.load_ticker.php` - drop file in
|
||||
[`$plugins directory`](../programmers/api-variables/variable-plugins-dir.md)
|
||||
|
||||
```php
|
||||
|
||||
<?php
|
||||
|
||||
// setup our function for fetching stock data
|
||||
function fetch_ticker($symbol)
|
||||
{
|
||||
// put logic here that fetches $ticker_info
|
||||
// from some ticker resource
|
||||
return $ticker_info;
|
||||
}
|
||||
|
||||
function smarty_function_load_ticker($params, $smarty)
|
||||
{
|
||||
// call the function
|
||||
$ticker_info = fetch_ticker($params['symbol']);
|
||||
|
||||
// assign template variable
|
||||
$smarty->assign($params['assign'], $ticker_info);
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
`index.tpl`
|
||||
|
||||
```smarty
|
||||
|
||||
{load_ticker symbol='SMARTY' assign='ticker'}
|
||||
|
||||
Stock Name: {$ticker.name} Stock Price: {$ticker.price}

## Obfuscating E-mail Addresses
|
||||
|
||||
Do you ever wonder how your email address gets on so many spam mailing
|
||||
lists? One way spammers collect email addresses is from web pages. To
|
||||
help combat this problem, you can make your email address show up in
|
||||
scrambled javascript in the HTML source, yet it it will look and work
|
||||
correctly in the browser. This is done with the
|
||||
[`{mailto}`](../designers/language-custom-functions/language-function-mailto.md) plugin.
|
||||
|
||||
```smarty
|
||||
|
||||
<div id="contact">Send inquiries to
|
||||
{mailto address=$EmailAddress encode='javascript' subject='Hello'}
|
||||
</div>
|
||||
|
||||
```
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> This method isn\'t 100% foolproof. A spammer could conceivably program
|
||||
> his e-mail collector to decode these values, but not likely\....
|
||||
> hopefully..yet \... wheres that quantum computer :-?.

# Troubleshooting
|
||||
|
||||
## Smarty/PHP errors
|
||||
|
||||
Smarty can catch many errors such as missing tag attributes or malformed
|
||||
variable names. If this happens, you will see an error similar to the
|
||||
following:
|
||||
|
||||
```
|
||||
Warning: Smarty: [in index.tpl line 4]: syntax error: unknown tag - '%blah'
|
||||
in /path/to/smarty/Smarty.class.php on line 1041
|
||||
|
||||
Fatal error: Smarty: [in index.tpl line 28]: syntax error: missing section name
|
||||
in /path/to/smarty/Smarty.class.php on line 1041
|
||||
```
|
||||
|
||||
|
||||
Smarty shows you the template name, the line number and the error. After
|
||||
that, the error consists of the actual line number in the Smarty class
|
||||
that the error occurred.
|
||||
|
||||
There are certain errors that Smarty cannot catch, such as missing close
|
||||
tags. These types of errors usually end up in PHP compile-time parsing
|
||||
errors.
|
||||
|
||||
`Parse error: parse error in /path/to/smarty/templates_c/index.tpl.php on line 75`
|
||||
|
||||
When you encounter a PHP parsing error, the error line number will
|
||||
correspond to the compiled PHP script, NOT the template itself. Usually
|
||||
you can look at the template and spot the syntax error. Here are some
|
||||
common things to look for: missing close tags for
|
||||
[`{if}{/if}`](../designers/language-builtin-functions/language-function-if.md) or
|
||||
[`{section}{/section}`](../designers/language-builtin-functions/language-function-section.md),
|
||||
or syntax of logic within an `{if}` tag. If you can\'t find the error, you might have to
|
||||
open the compiled PHP file and go to the line number to figure out where
|
||||
the corresponding error is in the template.
|
||||
|
||||

||||

# Escaping Smarty parsing
|
||||
|
||||
It is sometimes desirable or even necessary to have Smarty ignore
|
||||
sections it would otherwise parse. A classic example is embedding
|
||||
Javascript or CSS code in a template. The problem arises as those
|
||||
languages use the { and } characters which are also the default
|
||||
[delimiters](../language-builtin-functions/language-function-ldelim.md) for Smarty.
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> A good practice for avoiding escapement altogether is by separating
|
||||
> your Javascript/CSS into their own files and use standard HTML methods
|
||||
> to access them. This will also take advantage of browser script
|
||||
> caching. When you need to embed Smarty variables/functions into your
|
||||
> Javascript/CSS, then the following applies.
|
||||
|
||||
In Smarty templates, the { and } braces will be ignored so long as they
|
||||
are surrounded by white space. This behavior can be disabled by setting
|
||||
the Smarty class variable [`$auto_literal`](../../programmers/api-variables/variable-auto-literal.md) to
|
||||
false.
|
||||
|
||||
## Examples
|
||||
|
||||
```smarty
|
||||
<script>
|
||||
// the following braces are ignored by Smarty
|
||||
// since they are surrounded by whitespace
|
||||
function foobar {
|
||||
alert('foobar!');
|
||||
}
|
||||
// this one will need literal escapement
|
||||
{literal}
|
||||
function bazzy {alert('foobar!');}
|
||||
{/literal}
|
||||
</script>
|
||||
```
|
||||
|
||||
[`{literal}..{/literal}`](../language-builtin-functions/language-function-literal.md) blocks are used
|
||||
for escaping blocks of template logic. You can also escape the braces
|
||||
individually with
|
||||
[`{ldelim}`, `{rdelim}`](../language-builtin-functions/language-function-ldelim.md) tags or
|
||||
[`{$smarty.ldelim}`,`{$smarty.rdelim}`](../language-variables/language-variables-smarty.md#smartyldelim-smartyrdelim-languagevariablessmartyldelim)
|
||||
variables.
|
||||
|
||||
Smarty's default delimiters { and } cleanly represent presentational
|
||||
content. However, if another set of delimiters suit your needs better,
|
||||
you can change them with Smarty's
|
||||
[`$left_delimiter`](../../programmers/api-variables/variable-left-delimiter.md) and
|
||||
[`$right_delimiter`](../../programmers/api-variables/variable-right-delimiter.md) values.
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> Changing delimiters affects ALL template syntax and escapement. Be
|
||||
> sure to clear out cache and compiled files if you decide to change
|
||||
> them.

Template comments are surrounded by asterisks, and that is surrounded by

# Functions
|
||||
|
||||
Every Smarty tag either prints a [variable](./language-syntax-variables.md) or
|
||||
invokes some sort of function. These are processed and displayed by
|
||||
enclosing the function and its [attributes](./language-syntax-attributes.md)
|
||||
within delimiters like so: `{funcname attr1="val1" attr2="val2"}`.
|
||||
|
||||
## Examples
|
||||
|
||||
```smarty
|
||||
{config_load file="colors.conf"}
|
||||
|
||||
{include file="header.tpl"}
|
||||
{insert file="banner_ads.tpl" title="My Site"}
|
||||
|
||||
{if $logged_in}
|
||||
Welcome, <span style="color:{#fontColor#}">{$name}!</span>
|
||||
{else}
|
||||
hi, {$name}
|
||||
{/if}
|
||||
|
||||
{include file="footer.tpl"}
|
||||
```
|
||||
|
||||
- Both [built-in functions](../language-builtin-functions/index.md) and [custom
|
||||
functions](../language-custom-functions/index.md) have the same syntax within
|
||||
templates.
|
||||
|
||||
- Built-in functions are the **inner** workings of Smarty, such as
|
||||
[`{if}`](../language-builtin-functions/language-function-if.md),
|
||||
[`{section}`](../language-builtin-functions/language-function-section.md) and
|
||||
[`{strip}`](../language-builtin-functions/language-function-strip.md). There should be no need to
|
||||
change or modify them.
|
||||
|
||||
- Custom functions are **additional** functions implemented via
|
||||
[plugins](../../programmers/plugins.md). They can be modified to your liking, or you can
|
||||
create new ones. [`{html_options}`](../language-custom-functions/language-function-html-options.md)
|
||||
is an example of a custom function.

# Embedding Vars in Double Quotes
|
||||
|
||||
- Smarty will recognize [assigned](../../programmers/api-functions/api-assign.md)
|
||||
[variables](./language-syntax-variables.md) embedded in "double
|
||||
quotes" so long as the variable name contains only numbers, letters
|
||||
and under_scores. See [naming](https://www.php.net/language.variables)
|
||||
for more detail.
|
||||
|
||||
- With any other characters, for example a period(.) or
|
||||
`$object->reference`, then the variable must be surrounded by `` `backticks` ``.
|
||||
|
||||
- In addition, Smarty does allow embedded Smarty tags in double-quoted
|
||||
strings. This is useful if you want to include variables with
|
||||
modifiers, plugin or PHP function results.
|
||||
|
||||
## Examples
|
||||
```smarty
|
||||
{func var="test $foo test"} // sees $foo
|
||||
{func var="test $foo_bar test"} // sees $foo_bar
|
||||
{func var="test `$foo[0]` test"} // sees $foo[0]
|
||||
{func var="test `$foo[bar]` test"} // sees $foo[bar]
|
||||
{func var="test $foo.bar test"} // sees $foo (not $foo.bar)
|
||||
{func var="test `$foo.bar` test"} // sees $foo.bar
|
||||
{func var="test `$foo.bar` test"|escape} // modifiers outside quotes!
|
||||
{func var="test {$foo|escape} test"} // modifiers inside quotes!
|
||||
{func var="test {time()} test"} // PHP function result
|
||||
{func var="test {counter} test"} // plugin result
|
||||
{func var="variable foo is {if !$foo}not {/if} defined"} // Smarty block function
|
||||
|
||||
{* will replace $tpl_name with value *}
|
||||
{include file="subdir/$tpl_name.tpl"}
|
||||
|
||||
{* does NOT replace $tpl_name *}
|
||||
{include file='subdir/$tpl_name.tpl'} // vars require double quotes!
|
||||
|
||||
{* must have backticks as it contains a dot "." *}
|
||||
{cycle values="one,two,`$smarty.config.myval`"}
|
||||
|
||||
{* must have backticks as it contains a dot "." *}
|
||||
{include file="`$module.contact`.tpl"}
|
||||
|
||||
{* can use variable with dot syntax *}
|
||||
{include file="`$module.$view`.tpl"}
|
||||
```

# Variables
|
||||
|
||||
Template variables start with the $dollar sign. They can contain
|
||||
numbers, letters and underscores, much like a [PHP
|
||||
variable](https://www.php.net/language.variables). You can reference arrays
|
||||
by index numerically or non-numerically. Also reference object
|
||||
properties and methods.
|
||||
|
||||
[Config file variables](../language-variables/language-config-variables.md) are an exception to
|
||||
the \$dollar syntax and are instead referenced with surrounding
|
||||
\#hashmarks\#, or via the [`$smarty.config`](../language-variables/language-variables-smarty.md#smartyconfig-languagevariablessmartyconfig) variable.
|
||||
|
||||
## Examples
|
||||
|
||||
```smarty
|
||||
{$foo} <-- displaying a simple variable (non array/object)
|
||||
{$foo[4]} <-- display the 5th element of a zero-indexed array
|
||||
{$foo.bar} <-- display the "bar" key value of an array, similar to PHP $foo['bar']
|
||||
{$foo.$bar} <-- display variable key value of an array, similar to PHP $foo[$bar]
|
||||
{$foo->bar} <-- display the object property "bar"
|
||||
{$foo->bar()} <-- display the return value of object method "bar"
|
||||
{#foo#} <-- display the config file variable "foo"
|
||||
{$smarty.config.foo} <-- synonym for {#foo#}
|
||||
{$foo[bar]} <-- syntax only valid in a section loop, see {section}
|
||||
{assign var=foo value='baa'}{$foo} <-- displays "baa", see {assign}
|
||||
|
||||
Many other combinations are allowed
|
||||
|
||||
{$foo.bar.baz}
|
||||
{$foo.$bar.$baz}
|
||||
{$foo[4].baz}
|
||||
{$foo[4].$baz}
|
||||
{$foo.bar.baz[4]}
|
||||
{$foo->bar($baz,2,$bar)} <-- passing parameters
|
||||
{"foo"} <-- static values are allowed
|
||||
|
||||
{* display the server variable "SERVER_NAME" ($_SERVER['SERVER_NAME'])*}
|
||||
{$smarty.server.SERVER_NAME}
|
||||
|
||||
Math and embedding tags:
|
||||
|
||||
{$x+$y} // will output the sum of x and y.
|
||||
{assign var=foo value=$x+$y} // in attributes
|
||||
{$foo[$x+3]} // as array index
|
||||
{$foo={counter}+3} // tags within tags
|
||||
{$foo="this is message {counter}"} // tags within double quoted strings
|
||||
|
||||
Defining Arrays:
|
||||
|
||||
{assign var=foo value=[1,2,3]}
|
||||
{assign var=foo value=['y'=>'yellow','b'=>'blue']}
|
||||
{assign var=foo value=[1,[9,8],3]} // can be nested
|
||||
|
||||
Short variable assignment:
|
||||
|
||||
{$foo=$bar+2}
|
||||
{$foo = strlen($bar)} // function in assignment
|
||||
{$foo = myfunct( ($x+$y)*3 )} // as function parameter
|
||||
{$foo.bar=1} // assign to specific array element
|
||||
{$foo.bar.baz=1}
|
||||
{$foo[]=1} // appending to an array
|
||||
|
||||
Smarty "dot" syntax (note: embedded {} are used to address ambiguities):
|
||||
|
||||
{$foo.a.b.c} => $foo['a']['b']['c']
|
||||
{$foo.a.$b.c} => $foo['a'][$b]['c'] // with variable index
|
||||
{$foo.a.{$b+4}.c} => $foo['a'][$b+4]['c'] // with expression as index
|
||||
{$foo.a.{$b.c}} => $foo['a'][$b['c']] // with nested index
|
||||
|
||||
PHP-like syntax, alternative to "dot" syntax:
|
||||
|
||||
{$foo[1]} // normal access
|
||||
{$foo['bar']}
|
||||
{$foo['bar'][1]}
|
||||
{$foo[$x+$x]} // index may contain any expression
|
||||
{$foo[$bar[1]]} // nested index
|
||||
{$foo[section_name]} // smarty {section} access, not array access!
|
||||
|
||||
Variable variables:
|
||||
|
||||
$foo // normal variable
|
||||
$foo_{$bar} // variable name containing other variable
|
||||
$foo_{$x+$y} // variable name containing expressions
|
||||
$foo_{$bar}_buh_{$blar} // variable name with multiple segments
|
||||
{$foo_{$x}} // will output the variable $foo_1 if $x has a value of 1.
|
||||
|
||||
Object chaining:
|
||||
|
||||
{$object->method1($x)->method2($y)}
|
||||
|
||||
Direct PHP function access:
|
||||
|
||||
{time()}
|
||||
```
