What's the best way to clear the EE cache periodically without having to do it manually on sites?

I know there's the Cron Clean Cache plugin but was looking for something more like a system URL that we could hit on a CURL request in cron.

Or is setting up a template with this plugin the only route?

  • could I ask what your end solution was?

Like Bhashkar said, that code should work in either a PHP-enabled template or put in a plugin and then put in a template. Then call the template to clear cache.

A more advanced way, and probably the proper way to do it, is to create a simple module, which can use an Action URL. Stephen Lewis wrote a blog post about what Actions are. Basically, an action maps a url like http://domain.com/index.php?ACT=123 (where 123 is the action ID) to any method in your module. You can use it to trigger the cache clearing.

Say you add this method to your mod.my_addon.php file:

public function clear_cache()
    $this->EE->functions->clear_caching('all', '', TRUE);
    die('Cache cleared');

Then in your upd.my_addon.php file, inside the install() method, you need to add the action. Something like this:

$this->EE->db->insert('actions', array(
    'class'  => 'My_addon',
    'method' => 'clear_cache'

Where My_addon is the name of the class in the mod.my_addon.php file and clear_cache refers to the method you want to execute.

You could even add a check in your own clear_cache method for something like a secret key, so URL-hackers can't accidentally (or deliberately) trigger it.

Sounds like something one could learn in a certain workshop. ;)

  • dude - I'm gutted to be missing the workshop! I'd have definitely been there if not for the impending arrival. The action route is what I had in mind given we have other crons to hit other Action URLs. Mar 15, 2013 at 10:16


You can have the following code within a template (PHP allowed):

$this->EE =& get_instance();
$cache_type = 'all'; // It can be 'page' OR 'tag' OR 'db' OR 'sql' OR 'relationships'
$this->EE->functions->clear_caching($cache_type, '', TRUE);

and schedule template URL call with CRON job. I think, this would be the simplest solution for you.

For EE v2.+

  • meh, I don't like enabling PHP in templates when I don't have to. I'd be as well using the plugin and calling the same template without having PHP enabled. Mar 15, 2013 at 8:14
  • Yes, it would be fine to develop plugin having the code for clearing cache and call within template. Mar 15, 2013 at 8:22

You could use this module to trigger the cache clearing using Action ID https://devot-ee.com/add-ons/beanstalk-web-hook enter image description here
