How to use login_head action in WordPress

Welcome to a detailed exploration of the login_head action hook in WordPress! As a fellow developer, I get it—WordPress hooks can sometimes be a bit confusing, but they’re also incredibly powerful once you get the hang of them. Here, we’ll dive into how you can use the login_head action to customize the login page header effortlessly.

Example 1: Adding Custom CSS to the Login Page

Want to give your login page a unique look that matches your theme? You can easily add custom CSS by hooking into the login_head action.

    function weplugins_custom_login() {
        echo '<link rel="stylesheet" type="text/css" href="' . get_bloginfo('stylesheet_directory') . '/customlogin.css" />';
    }
    add_action('login_head', 'weplugins_custom_login');
    

Example 2: Executing Custom Functions

Whether you need to add a tracking script or modify HTML, you can execute custom functions when the login page is loaded.

    function weplugins_execute_on_login_head_event(){
        // Custom code to execute on login page load.
    }
    add_action("login_head", "weplugins_execute_on_login_head_event");
    

Example 3: Removing a Hook Callback

If at any point you need to remove a previously registered hook, use remove_action to ensure it no longer executes.

    remove_action("login_head", "weplugins_execute_on_login_head_event");
    

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