Name

templateExists() — checks whether the specified template exists

Description

bool templateExists(string template);

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

Example 14.48. templateExists()

This example uses $_GET['page'] to {include} a content template. If the template does not exist then an error page is displayed instead. First the page_container.tpl

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

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

{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( !$smarty->templateExists($mid_template) ){
    $mid_template = 'page_not_found.tpl';
}
$smarty->assign('content_template', $mid_template);

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

?>
