How to use clean_user_cache action in WordPress

Understanding and using WordPress hooks can be a game-changer for your website development. The clean_user_cache action is one such hook that fires right after a user’s cache is cleaned. If you’re someone who likes to keep your WordPress site efficient, knowing how to use this hook is a must. You can add this to your theme’s functions.php file or better yet, create a custom plugin. This way, you won’t lose your customization when your theme updates.

Let’s dive into some live examples to see how you can put clean_user_cache to work in your projects.

Example 1: Basic Usage of clean_user_cache

Here’s how you can register the action and create a function that executes when a user’s cache is cleared.

    function weplugins_execute_on_clean_user_cache_event($user_id, $user){
       // Custom functionality for when the user's cache is cleaned
    }
    add_action("clean_user_cache", "weplugins_execute_on_clean_user_cache_event", 10, 2);
    

Example 2: Removing the Action

If you need to remove this action after it’s no longer needed, you can do so using the following code.

    remove_action("clean_user_cache", "weplugins_execute_on_clean_user_cache_event", 10, 2);
    

Example 3: Advanced Customization

In this example, imagine you need to log an entry every time a user’s cache is cleaned. You can expand the function to add this logging feature.

    function weplugins_log_user_cache_cleaning($user_id, $user){
        // Log the cache cleaning event
        error_log("User cache cleaned for user ID: " . $user_id);
    }
    add_action("clean_user_cache", "weplugins_log_user_cache_cleaning", 10, 2);
