<code class="methodsynopsis"><span class="type">bool </span><span class="methodname">template_exists</span>(<span class="methodparam"><span class="type">string </span><span class="parameter">template</span></span>);</code><p>

<a name="id3107270"></a><p class="title"><b>Example 13.26. template_exists()</b></p>
<div class="example-contents">
<p>
This example uses <code class="literal">$_GET['page']</code> to
<a class="link" href="language.function.include.html" title="{include}"><code class="varname">{include}</code></a>
a content template. If the template does not exist then an error page
is displayed instead. First the <code class="filename">page_container.tpl</code>
</p>
<pre class="programlisting">
<html>
<head><title>{$title}</title></head>
<body>
{include file='page_top.tpl'}
{* include middle content page *}
{include file=$content_template}
{include file='page_footer.tpl'}
</body>
</pre>
<p>
And the php script
</p>
<pre class="programlisting">
<?php
// set the filename eg index.inc.tpl
$mid_template = $_GET['page'].'.inc.tpl';
if( !$smarty->template_exists($mid_template) ){

$smarty->assign('content_template', $mid_template);
