Variables assigned from PHP

Variables assigned from PHP are referenced by preceding them with a dollar ($) sign.

Examples

<?php
use Smarty\Smarty;
$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 .
This weeks meeting is in New York.

Associative 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

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

Properties of 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 />
