+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.
+
+This example uses `$_GET['page']` to
+[`{include}`](#language.function.include) a content template. If the
+template does not exist then an error page is displayed instead. First
+the `page_container.tpl`
+
+
+    <html>
+    <head><title>{$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');
+
+    ?>
+
+

+[`{include}`](#language.function.include) and
+[`{insert}`](#language.function.insert)
