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');
?>
