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!

Variables assigned from PHP {#language.assigned.variables}
|
|
===========================
|
|
|
|
Assigned variables that are referenced by preceding them with a dollar
|
|
(`$`) sign.
|
|
|
|
PHP code
|
|
|
|
|
|
<?php
|
|
|
|
$smarty = new Smarty();
|
|
|
|
$smarty->assign('firstname', 'Doug');
|
|
$smarty->assign('lastname', 'Evans');
|
|
$smarty->assign('meetingPlace', 'New York');
|
|
|
|
$smarty->display('index.tpl');
|
|
|
|
?>
|
|
|
|
`index.tpl` source:
|
|
|
|
|
|
Hello {$firstname} {$lastname}, glad to see you can make it.
|
|
<br />
|
|
{* this will not work as $variables are case sensitive *}
|
|
This weeks meeting is in {$meetingplace}.
|
|
{* this will work *}
|
|
This weeks meeting is in {$meetingPlace}.
|
|
|
|
|
|
|
|
This above would output:
|
|
|
|
|
|
Hello Doug Evans, glad to see you can make it.
|
|
<br />
|
|
This weeks meeting is in .
|
|

Associative arrays {#language.variables.assoc.arrays}
|
|
------------------
|
|
|
|
You can also reference associative array variables by specifying the key
|
|
after a dot \".\" symbol.
|
|
|
|
|
|
<?php
|
|
$smarty->assign('Contacts',
|
|
array('fax' => '555-222-9876',
|
|
'email' => 'zaphod@slartibartfast.example.com',
|
|
'phone' => array('home' => '555-444-3333',
|
|
'cell' => '555-111-1234')
|
|
)
|
|
);
|
|
$smarty->display('index.tpl');
|
|
?>
|
|
|
|
|
|
|
|
`index.tpl` source:
|
|
|
|
|
|
{$Contacts.fax}<br />
|
|
{$Contacts.email}<br />
|
|
{* you can print arrays of arrays as well *}
|
|
{$Contacts.phone.home}<br />
|
|
{$Contacts.phone.cell}<br />
|
|
|
|
|
|
|
|
this will output:
|
|
|
|
|
|
555-222-9876<br />
|
|
zaphod@slartibartfast.example.com<br />
|
|
555-444-3333<br />
|
|
555-111-1234<br />
|
|
|
|
|
|
|
|
Array indexes {#language.variables.array.indexes}
|
|
-------------
|
|
|
|
You can reference arrays by their index, much like native PHP syntax.
|
|
|
|
|
|
<?php
|
|
$smarty->assign('Contacts', array(
|
|
'555-222-9876',
|
|
'zaphod@slartibartfast.example.com',
|
|
array('555-444-3333',
|
|
'555-111-1234')
|
|
));
|
|
$smarty->display('index.tpl');
|
|
?>
|
|
|
|
|
|
|
|
`index.tpl` source:
|
|
|
|
|
|
{$Contacts[0]}<br />
|
|
{$Contacts[1]}<br />
|
|
{* you can print arrays of arrays as well *}
|
|
{$Contacts[2][0]}<br />
|
|
{$Contacts[2][1]}<br />
|
|
|
|
|
|
|
|
This will output:
|
|
|
|
|
|
555-222-9876<br />
|
|
zaphod@slartibartfast.example.com<br />
|
|
555-444-3333<br />
|
|
555-111-1234<br />
|
|
|
|
|
|
|
|
Objects {#language.variables.objects}
|
|
-------
|
|
|
|
Properties of [objects](#advanced.features.objects) assigned from PHP
|
|
can be referenced by specifying the property name after the `->` symbol.
|
|
|
|
|
|
name: {$person->name}<br />
|
|
email: {$person->email}<br />
|
|
|
|
|
|
|
|
this will output:
|
|
|
|
|
|
name: Zaphod Beeblebrox<br />
|
|
email: zaphod@slartibartfast.example.com<br />
|
|
