使用remove_submenu_page删除自定义标题子页面

Question

如何删除Header并Background从子页面Appearance的子菜单？

remove_submenu_page很好用Themes和Menus,但我似乎无法找到一种方法来删除Header和Background!

这是一个例子:

   // working just fine:
   remove_submenu_page( 'themes.php', 'themes.php' );
   remove_submenu_page( 'themes.php', 'nav-menus.php' ); 
   // not working:
   remove_submenu_page( 'themes.php', 'themes.php?page=custom-header' ); 
   remove_submenu_page( 'themes.php', 'themes.php?page=custom-background' ); 

Answer 1

在主题的function.php中使用以下代码

add_action( 'after_setup_theme','remove_twentyeleven_options', 100 );
function remove_twentyeleven_options() {

remove_custom_background();
remove_custom_image_header();

}
