Name

clearCache() — clears the cache for a specific template

Description

void clearCache(string template,
                string cache_id,
                string compile_id,
                int expire_time);
  • If you have multiple caches for a template, you can clear a specific cache by supplying the cache_id as the second parameter.

  • You can also pass a $compile_id as a third parameter. You can group templates together so they can be removed as a group, see the caching section for more information.

  • As an optional fourth parameter, you can supply a minimum age in seconds the cache file must be before it will get cleared.

    Note

    Since Smarty version 3.1.14 it is possible to delete cache files by their individual expiration time at creation by passing constant SMARTY::CLEAR_EXPIRED as fourth parameter.

Example 173. clearCache()



<?php
// clear the cache for a template
$smarty->clearCache('index.tpl');

// clear the cache for a particular cache id in an multiple-cache template
$smarty->clearCache('index.tpl''MY_CACHE_ID');
?>
