add_submenu_page ( "options-general.php" , "Crunchify Plugin" , "Crunchify Plugin" , "manage_options" , "crunchify-hello-world" , "crunchify_hello_world_page" ) ;
}
add_action ( "admin_menu" , "crunchify_add_menu" ) ;

Kami menggunakan add_action WordPress hook untuk menambahkan submenu untuk plugin kami.
