# template_exists()

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 `$_GET['page']` to `{include}` a content template. If the template does not exist then an error page is displayed instead. First the `page_container.tpl`
`<html> <head><title>{$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->template_exists($mid_template) ){ $mid_template = 'page_not_found.tpl'; } $smarty->assign('content_template', $mid_template); $smarty->display('page_container.tpl'); ?>`

See also `display()`, `fetch()`, `{include}` and `{insert}`
