BuddyPress.org

For a BuddyPress Site I have a function for putting “Groups”, or other menu items in the wp-admin bar.

This is it

function bcustom_adminbar_menu() {
global $wp_admin_bar;
if ( !is_user_logged_in() ) { return; }
$wp_admin_bar->add_menu( array(
'id' => 'bcustom_menu',
'title' => __( 'Groups' ),
'href' => network_home_url('/groups/')
)
);
}
add_action( 'admin_bar_menu', 'bcustom_adminbar_menu', 15 );

However if the bp root blog is not the network home then the function is incorrect.

Could somebody please help me to change the line

'href' => network_home_url('/groups/')

so that it goes to or is equivalent to

<a href=&quot;/groups/">Groups</a>

Thanks.
