Smarty included file caching
Wednesday, May 30th, 2007Smarty is very good templating system for every PHP application. Once I coded one application using Smarty and Apache mod rewrite. I had one template file i witch i included other template files. After some time my project had very high traffic so i needed to on cache. You probably know that Smarty does not have cache future for included file, so i googled for some time and found some useful smarty hack. I added this hack to smarty core files and wow it worked, all i had to do is just add variable to template file inclusion in example:
1 | {include file='includedfile.tpl' __cache__=120} |
Where __cache__ shows that i start cache for 120 second everything worked fine until i browsed to other pages. Main bug of this hack is you can not use paging on your application. To solve this problem i edited smary code and added __id__ variable to Smarty included template files. It works very simple in example:
index.php file:
1 2 3 4 5 6 7 | <?php if ($_GET['page']) { $smarty->assign('page', $_GET['page']); //getting dynamic content } $smarty->display('main.tpl'); ?> |
main.tpl
1 2 3 4 5 6 7 8 | <html>
<head>
<title>{$pagetitle}</title>
</head>
<body>
{include file='dynamiccontent.tpl' __cache__=3600 __id__=$page}
</body>
</html> |
Variable __id__ assigns in witch dynamic content page I am.
