Comparing changes: https://github.com/smarty-php/smarty/compare/v4.3.1...v4.4.1 It is noticeable that Smarty 4.3.1 does not officially support PHP 8.3. Is only supported with 4.4.0. Remark: During tests with Smarty 4.5.1, it was noticed that the following warning occurs: Deprecated: Using the unregistered function "function_exists" in a template is deprecated and will be removed in a future version. Use Smarty::registerPlugin to explicitly register a custom modifier. As of Smarty 5.X.X, templates must be revised again. The Smarty release 5.0.2 is already officially available. However, integration into FlatPress is not entirely trivial.

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');
|
|
|
|
?>
