How to use muplugins_loaded action in WordPress

To use the muplugins_loaded action, you first need to register it using add_action. You can write this code into your theme’s functions.php or in a custom WordPress plugin. Personally, I always prefer creating a custom WordPress plugin to ensure nothing breaks when updating your theme in the future.

Example 1: Basic Usage of muplugins_loaded

Here’s a simple example of how to use this hook. We define a function, weplugins_execute_on_muplugins_loaded_event, and register it using add_action.

    function weplugins_execute_on_muplugins_loaded_event(){
        // Code to be executed when muplugins_loaded action occurs.
    }
    // Add the action
    add_action("muplugins_loaded", "weplugins_execute_on_muplugins_loaded_event");
    

Example 2: Removing the Hook Callback

Sometimes, you’ll need to remove a registered hook. Here’s how you can use remove_action to remove the muplugins_loaded action.

    remove_action("muplugins_loaded", "weplugins_execute_on_muplugins_loaded_event");
    

Please ensure you provide the same callback function name, priority, and number of arguments while removing the hook callback.

Example 3: Handling Priority and Arguments

When the same hook is used multiple times, you might want to specify the priority of your function. Here’s how you can do it while defining your function.

    function weplugins_custom_muplugins_loaded_function($arg){
        // Your custom code using $arg
    }
    // Add the action with priority and argument
    add_action("muplugins_loaded", "weplugins_custom_muplugins_loaded_function", 10, 1);
