Add menu bar above the WordPress administration bar - wordpress

Question

I wish to add our own service menu above the WordPress administration bar in the administration area. I do not wish to hack the WordPress system, but I cannot find a hook.
Is there a method?

Answer 1

You can add extra menu items in your administrator menu bar instead of removing/replacing the menu bar.
Below is an example which will insert one menu item with two sub menu items. Just paste the code in your functions.php and log in to your WordPress as admin. If everything goes right then you can see an extra menu in your administrator bar. To accomplish this, WordPress provided the admin_bar_menu hook:
add_action('admin_bar_menu', 'my_custom_menu', 1000);
function my_custom_menu()
{
global $wp_admin_bar;
if(!is_super_admin() || !is_admin_bar_showing()) return;
// Add Parent Menu
$argsParent=array(
'id' => 'myCustomMenu',
'title' => 'Services',
'href' => false
);
$wp_admin_bar->add_menu($argsParent);
// Add Sub Menus
$argsSub1=array(
'parent' => 'myCustomMenu',
'title' => 'Visit Heera IT',
'href' => 'http://heera.it',
'meta' => array('target' => '_blank')
);
$wp_admin_bar->add_menu($argsSub1);
$argsSub2=array(
'parent' => 'myCustomMenu',
'title' => 'Visit StackOverflow',
'href' => 'http://stackoverflow.com/',
'meta' => array('target' => '_blank')
);
$wp_admin_bar->add_menu($argsSub2);
}
