Add a Submenu to the WordPress Admin Bar

By  on  

A while back I wrote Add Menu Items to the WordPress Admin Menu, a post detailing how you can add items to the left side, existing "posts" menu bar.  Adding menu items has served me well but it's not as customized as I would like -- I'm still adapting to WordPress instead of WordPress adapting to me.  By creating a custom top bar menu, I can mix and match links all I want!

Like adding functionality to your theme and other admin area, the directives will go in your theme's functions.php file.  The code itself should be self explanatory:

function create_dwb_menu() {
	global $wp_admin_bar;

	$menu_id = 'dwb';
	$wp_admin_bar->add_menu(array('id' => $menu_id, 'title' => __('DWB'), 'href' => '/'));
	$wp_admin_bar->add_menu(array('parent' => $menu_id, 'title' => __('Homepage'), 'id' => 'dwb-home', 'href' => '/', 'meta' => array('target' => '_blank')));
	$wp_admin_bar->add_menu(array('parent' => $menu_id, 'title' => __('Drafts'), 'id' => 'dwb-drafts', 'href' => 'edit.php?post_status=draft&post_type=post'));
	$wp_admin_bar->add_menu(array('parent' => $menu_id, 'title' => __('Pending Comments'), 'id' => 'dwb-pending', 'href' => 'edit-comments.php?comment_status=moderated'));
}
add_action('admin_bar_menu', 'create_dwb_menu', 2000);

Setting an id on the parent menu item allows you to use the parent key for submenu items; the rest of the keys are easy to figure out.  With the menu created, you simply need to add the WordPress hook and specificity to add it!

    Thank you Mr. Walsh! I needed this. Awesome!

  3. This is super easy!though I wish they had some kind of visual interface to do this, as it is there is Joomla and Drupal.

    What would be great would be a WP plugin that uses the built-in WordPress “Links” (http://codex.wordpress.org/Template_Tags/wp_list_bookmarks) and creates WP Admin Bar menus for each link category, and then adds the links from each category to the menu.

    Seems like a nice way to leverage the built-in WP Links feature for something that would actually be useful.

    Shouldn’t be too hard to do …. I might have a go when I get time.

    Thanks for the article.

    Hi.

    Thanks for this.

    Is there a way to open the URL in a new window?
    Here is my code:

    function create_dwb_menu() {
    	global $wp_admin_bar;
    
    	$menu_id = 'dwb';
    	$wp_admin_bar->add_menu(array('id' => $menu_id, 'title' => __('NEW MENU ITEM'), 'href' => 'http://website.com/'));
    }
    add_action('admin_bar_menu', 'create_dwb_menu', 2000);
    
  6. To have this open in a new window, add in the meta option, like this: 'meta' => array( 'target' => '_blank' )

    Thank you. I much use this code for my next plugin :)

Wrap your code in <pre class="{language}"></pre> tags, link to a GitHub gist, JSFiddle fiddle, or CodePen pen to embed!
