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');
|
||
|
|
|
||
|
|
?>
|
||
|
|
|
||
|
