How to use do_faviconico action in WordPress

Alright, let’s dive into the do_faviconico action hook. This hook is super useful when you need to execute some custom code whenever the favicon.ico file is served. You can register it using add_action, and it’s best to place this code in a custom WordPress plugin to ensure your work remains intact during theme updates.

Here’s a detailed breakdown and some live examples to help you understand how to use the do_faviconico action hook.

do_faviconico action

Fires when serving the favicon.ico file.

Live Example 1: Basic Hook Registration

In this example, we define a function weplugins_execute_on_do_faviconico_event and register it with the do_faviconico action hook.

    function weplugins_execute_on_do_faviconico_event(){
        // Your custom code here
    }
    // Add the action
    add_action( "do_faviconico", "weplugins_execute_on_do_faviconico_event");
    

Live Example 2: Removing a Hook Callback

If you need to remove a previously registered hook callback, you can use remove_action. Ensure you provide the same callback function name, priority, and number of arguments.

remove_action( "do_faviconico", "weplugins_execute_on_do_faviconico_event");

Live Example 3: Adding Priority

You can also specify the priority of the hook. Here, we set the priority to 10 (the default) and pass 1 argument to the callback function.

    function weplugins_custom_favicon_logic(){
        // Custom logic here
    }
    add_action( "do_faviconico", "weplugins_custom_favicon_logic", 10, 1);
    

Sometimes, you need to remove a registered hook, and you can use remove_action to remove the do_faviconico action.
