Hi Tony,

I had a similar need in controlling the WP-Admin bar…. in my case I wanted to hide elements in the admin-toolbar…. but you can use the same logic using the WP function add_node () and remove_node() to gain control over what to users can see.

I used the following code in my custom functions file located in the mu-plugin folder:

////////////////////////////////////////////////////////////////////////////////
//Kampester Custom function Adapted For MU Buddypress Newtwork  - New function
////////////////////////////////////////////////////////////////////////////////


function admin_bar_remove_this(){
     global $wp_admin_bar;
    if(!is_super_admin()){
     $wp_admin_bar->remove_node('blogs-menu');
    $wp_admin_bar->remove_node('account-menu');
    $wp_admin_bar->remove_node('new-content');
    $wp_admin_bar->remove_node('my-sites');
       }
        $wp_admin_bar->remove_node('wp-logo');
           }
        add_action('wp_before_admin_bar_render','admin_bar_remove_this');

To start I used this function to get a entire list of all the nodes available in my install – this code will place menu item in your admin-bar that you can use to identify the elements naming convention. I got the code from the WP codex….

Hope this helps.

add_action( 'wp_before_admin_bar_render', 'add_all_node_ids_to_toolbar');
 
 function add_all_node_ids_to_toolbar() {
 
   global $wp_admin_bar;
   $all_toolbar_nodes = $wp_admin_bar->get_nodes();
       
   if($all_toolbar_nodes){
   
     // add a top-level Toolbar item called "Node Id's" to the Toolbar
     $args = array('id' => 'node_ids', 'title' => 'Node ID\'s');
     $wp_admin_bar->add_node($args);
     
     // add all current parent node id's to the top-level node.
     foreach ( $all_toolbar_nodes as $node  ) {
       if(isset($node->parent) && $node->parent){
       
         $args = array(
           'id' => 'node_id_'.$node->id, // prefix id with "node_id_" to make it a unique id
           'title' => $node->id,
           'parent' => 'node_ids'
           // 'href' => $node->href,
         );
         // add parent node to node "node_ids"
         $wp_admin_bar->add_node($args);
       }
     }
     
     // add all current Toolbar items to their parent node or to the top-level node
     foreach ( $all_toolbar_nodes as $node  ) {
     
       $args = array(
         'id' => 'node_id_'.$node->id, // prefix id with "node_id_" to make it a unique id
         'title' => $node->id,
         // 'href' => $node->href,
       );
       
       if(isset($node->parent) && $node->parent){
         $args['parent'] = 'node_id_'.$node->parent;
       } else {
         $args['parent'] = 'node_ids';
       }
       
       $wp_admin_bar->add_node($args);
     }
   }
