How to add admin bar only page?

Question

I successfully managed to create admin bar item using this:

add_action('admin_bar_menu', 'toolbar_link_to_mypage', 999);
function toolbar_link_to_mypage($wp_admin_bar){
    global $wp_admin_bar;

    $theme_menu = array(
        'id' => 'theme_page',
        'title' => __('test', 'test'),
        'href' => 'http://mysite.com/my-page/',
        'meta' => array('class' => 'test')
    );

    $wp_admin_bar->add_node($theme_menu);
}

But I can't figure out what is the correct way to create an admin panel OPTIONS PAGE (not sub-menu item! Two answers are about sub-menus already) for 'href' => '', parameter. I can't simply use add_menu_page(); because that would attach it to left navigation as well. Any help would be great!

Answer 1

You have to create a new array for the new item and pass the parent parameter as the id of this already created item. In your case, the args array should be like this:

$args = array(
    'id' => 'my-item',
    'title' => 'My Item',
    'href' => '#',
    'parent' => 'theme_page',
    'meta' => array(
        'title' => __('Click Me'),
    ),
);

This post has a complete explanation of how and where you can add items to the admin bar and the usage of the parent parameter.

Here is the code that will work :

 add_action('admin_bar_menu', 'toolbar_link_to_mypage', 999);
function toolbar_link_to_mypage($wp_admin_bar){
    global $wp_admin_bar;

    $wp_admin_bar->add_menu(array(
        'id' => 'theme_page',
        'title' => __('test', 'test'),
        'href' => 'http://mysite.com/my-page/',
        'meta' => array('class' => 'test')
    ));

   $wp_admin_bar->add_menu(array(
        'id' => 'theme_page_child',
        'title' => __('Child test', 'child-test'),
        'href' => 'http://mysite.com/my-page/',
        'meta' => array('class' => 'child-test'),
    'parent' => 'theme_page'
    ));

}

In the first add_menu I have added a parent link In the next add_menu I am using another attribute 'parent' which is referring to the id of 'parent' here the 'parent' is 'theme_page' we created above.
