Question

I’ve got a cms, each page stores the time that it was last updated in a database. I’ve got caching set up in smarty (3.1), but I want to be able to clear the cache and force it to create a new cache file if the page was updated since the last saved cache file, but to do that I need to know when the cached file was created.

Is there a way of getting the timestamp of the cached file?

Thanks

I have recently answered a similar question: Smarty cache site properties in database

<?php
// fill these if you do cache grouping and or have different compiles of the same template
$template = 'foobar.tpl';
$cache_id = null;
$compile_id = null;

$smarty = new Smarty();
$tpl = $smarty->createTemplate($template, $cache_id, $compile_id);
if ($tpl->isCached() && $tpl->cached->timestamp < $yourTimestampFromDB) {
  $smarty->clearCache($template, $cache_id, $compile_id);
}
