template_exists() -- checks whether the specified template exists

Description

bool template_exists ( string template)

It can accept either a path to the template on the filesystem or a resource string specifying the template.

Example 13-1. template_exists()

This example uses $_GET['page'] to include a content template. If the template doesnt exist then an error page is displayed instead.

The page_container.tpl


<html>
<head><title>{$title}</title></head>
<body>
{include file='page_top.tpl'}

{* include middle content page *}
{include file=$page_mid}

{include file='page_footer.tpl'}
</body>

and the php script


<?php

// set the filename eg index.inc.tpl
$mid_template = $_GET['page'].'.inc.tpl';

if( !$smarty->template_exists($mid_template) ){
    $mid_template = 'page_not_found.inc.tpl';
}
$smarty->assign('page_mid', $mid_template);

$smarty->display('page_container.tpl');

?>
