I've created a submenu in wordpress using add_submenu_page:

add_submenu_page(null,'Page Title','Page Title','administrator','page-slug','page-callback');

I want to create another page like this with the condition that the page will be totally blank without creating a new file does wordpress have a function like this?I want it because I want to generate and download an xml file there and if the page has headers and footers the page downloads them too.Any Sugestion? Thank You.

Try something like this: in the load hook, you can ouput your xml code. u

function my_menu_pages() {
    $hook = add_submenu_page(
            null, 'Page Title', 'Page Title', 'administrator', 'sub-menu-slug', function() {
    }
    );
    add_action('load-' . $hook, function() {
        // add your xml code here, 
        // you will get a blank page to start with
        exit;
    });
}

add_action('admin_menu', 'my_menu_pages');

Don't try to do this with admin menus/ admin pages. It is going to be a headache. Set up an AJAX API callback and you can have complete control of the output with no worries about any other markup since there won't be any.

function download_xml_wpse_144156() {
  // generate your XML and echo it
  die();
}
add_action('wp_ajax_grab_my_xml', 'download_xml_wpse_144156');
add_action('wp_ajax_grab_my_xml', 'download_xml_wpse_144156');

You can retrieve the XML file with a request to //example.com/wp-admin/admin-ajax.php?action=grab_my_xml. Note that grab_my_xml is the trailing part of the two action hooks. You can set that to whatever you like.

  • Yes, you must be using this incorrectly. It does work. – s_ha_dum May 12 '14 at 15:26

Add blank page without wordpress functionality, so you can add your own custom content and controls using your own markup.

add_action( 'admin_menu', 'my_admin_menu' );
        function my_admin_menu() {
            add_menu_page( 'Page Title', 'Menu Name', 'manage_options', 'page_menu_slug', 'page_function', 'dashicons-carrot', 6 );
            add_action( 'admin_enqueue_scripts', 'load_custom_wp_admin_style' );
        }
  • Please edit your answer, and add an explanation: why could that solve the problem? – fuxia Jun 19 '18 at 9:48
