Having troubles with add_menu_page() function

  • I am working with a plugin and I’m trying to understand why I’m not able to add menu page. Interestingly enough, I acceidentally called the function that’s in charge of adding my pages in my template plugin project and it worked. So does anyone know why the add_menu_page function isn’t working in my plugin but will work in another one.

    (Following function is inside a class called MenuCreation)

    public static function createMenu() {
        $menu_pages = get_option('menu_pages');
        $menu_pages['home'] = add_menu_page(
			'Welcome to Manager',
			'Manager',
			'administrator',
			'home',
			'MenuCreation::menuCallback',
			'dashicons-layout'
		);
}

    (Inside a separate Admin class)
    add_action('admin_menu', array('MenuCreation', 'createMenu'));

  • I may sound silly but is the plugin active and MenuCreation class is included from where you are calling the hook.

    Thanks.

    Yes it is. I double checked if it was being loaded with my autoloader and even used a require statement so that’s not the issue. After some more digging I found that the add_action(‘admin_menu’) only works in the main plugin file. When I call it anywhere else it doesn’t load. I can even call the add_action in another main file for another plugin and it will still work but for some odd reason it doesn’t work in other files.

    It wouldn’t be the subordinate page that’s preventing your menu page, there is no problem doing so by itself. It’s likely because your action callback was added after “admin_menu” action had already fired. Perhaps your Admin class was instantiated too late or at least the class method with the add_action() call executed too late.
