Updated calls to current Smarty API (register_function()/register_modifier()/register_block() -> registerPlugin(); assign_by_ref() -> assignByRef()). Fixed file includes in templates with quotes. Removed SmartyValidate.class.php includes. Still work in progress as some errors still appear!

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.
|
|
|
|
|
|
<?php
|
|
|
|
$smarty->left_delimiter = '<!--{';
|
|
$smarty->right_delimiter = '}-->';
|
|
|
|
$smarty->assign('foo', 'bar');
|
|
$smarty->assign('name', 'Albert');
|
|
$smarty->display('example.tpl');
|
|
|
|
?>
|
|
|
|
|
|
|
|
Where the template is:
|
|
|
|
|
|
Welcome <!--{$name}--> to Smarty
|
|
<script language="javascript">
|
|
var foo = <!--{$foo}-->;
|
|
function dosomething() {
|
|
alert("foo is " + foo);
|
|
}
|
|
dosomething();
|
|
</script>
