nocache

|
|
|
You can explicitly pass name/value pairs, or associative arrays
|
|
containing the name/value pairs.
|
|
|
|
If you pass the optional third `nocache` parameter of TRUE, the variable
|
|
is assigned as nocache variable. See
|
|
[`Cacheability of Variables`](#cacheability.variables) for details.

> **Note**
|
|
>
|
|
> When you assign/register objects to templates, be sure that all
|
|
> properties and methods accessed from the template are for presentation
|
|
> purposes only. It is very easy to inject application logic through
|
|
> objects, and this leads to poor designs that are difficult to manage.

<?php
|
|
// passing name/value pairs
|
|
$smarty->assign('Name', 'Fred');
|
|
$smarty->assign('Address', $address);
|
|
|
|
// passing an associative array
|
|
$smarty->assign(array('city' => 'Lincoln', 'state' => 'Nebraska'));
|
|
|
|
// passing an array
|
|
$myArray = array('no' => 10, 'label' => 'Peanuts');
|
|
$smarty->assign('foo',$myArray);
|
|
|
|
// passing a row from a database (eg adodb)
|
|
$sql = 'select id, name, email from contacts where contact ='.$id;
|
|
$smarty->assign('contact', $db->getRow($sql));
|
|
?>
|
|
|
|
These are accessed in the template with
|
|
|
|
|
|
{* note the vars are case sensitive like php *}
|
|
{$Name}
|
|
{$Address}
|
|
{$city}
|
|
{$state}
|
|
|
|
{$foo.no}, {$foo.label}
|
|
{$contact.id}, {$contact.name},{$contact.email}
|
|
|
