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');
?>
