How to use expiration_of_site_transient_transient filter in WordPress

If you’ve ever been curious about harnessing the full potential of WordPress hooks, you’re in the right place! Today, we’re diving into the expiration_of_site_transient_transient filter. This hook is quite handy when you want to modify the expiration of a site transient. Let’s explore how you can use it effectively in your projects.

Example 1: Modifying Transient Expiration

Let’s say you want to adjust the expiration time of a transient to better suit your site’s caching needs. Here’s how you can do it:

    function weplugins_modify_expiration_of_site_transient_transient($expiration, $value, $transient) { 
        // Custom logic for modifying expiration
        return $expiration; 
    }
    add_filter("expiration_of_site_transient_transient", "weplugins_modify_expiration_of_site_transient_transient", 10, 3);
    

Example 2: Conditional Expiration Adjustment

If you need to conditionally change the expiration based on certain transient names, this example shows you how:

    function weplugins_conditional_expiration($expiration, $value, $transient) {
        if ($transient === 'special_transient') {
            $expiration = 3600; // Set to 1 hour if it's a special transient
        }
        return $expiration;
    }
    add_filter("expiration_of_site_transient_transient", "weplugins_conditional_expiration", 10, 3);
    

Example 3: Removing a Hook Callback

Sometimes you might need to remove a previously added filter to avoid conflicts. Here’s how you can do it:

    remove_filter("expiration_of_site_transient_transient", "weplugins_modify_expiration_of_site_transient_transient", 10, 3);
    

Remember to use the same callback function name, priority, and number of arguments when removing the filter.
