WordPress Hook Generator

Instructions

When the user wants to add a WordPress hook:

1. Determine hook type:

   • Action (add_action): Performs an action, no return value
   • Filter (add_filter): Modifies data, must return a value

2. Apply naming convention:

   • Prefix: retrologin_
   • Example: retrologin_login_head, retrologin_custom_message

3. Create callback function:

   • Use namespace: Retrologin\
   • Or use string callback: 'retrologin_callback'

4. Register the hook:

   • Actions: add_action('hook_name', 'callback', priority, args)
   • Filters: add_filter('hook_name', 'callback', priority, args)

Example

// Action: Enqueue assets on login page
add_action('login_enqueue_scripts', 'retrologin_enqueue_assets');

function retrologin_enqueue_assets(): void {
    wp_enqueue_style('retrologin-login', plugins_url('dist/assets/login.css', __FILE__));
}

// Filter: Change logo URL
add_filter('login_headerurl', 'retrologin_login_logo_url');

function retrologin_login_logo_url(): string {
    return home_url('/');
}
