template_exists()checks whether the specified template existsDescriptionbooltemplate_existsstringtemplate
It can accept either a path to the template on the filesystem or a
resource string specifying the template.
template_exists()
This example uses $_GET['page'] to
{include}
a content template. If the template does not exist then an error page
is displayed instead. First the page_container.tpl{$title}
{include file='page_top.tpl'}
{* include middle content page *}
{include file=$content_template}
{include file='page_footer.tpl'}
]]>
And the php script
template_exists($mid_template) ){
$mid_template = 'page_not_found.tpl';
}
$smarty->assign('content_template', $mid_template);
$smarty->display('page_container.tpl');
?>
