Topbar add loginname via php

[DStatG]

Hello,

I want to show the login name of the users in the topbar.
Here is the code which i use in the functions php:

add_filter( 'wp_nav_menu_items', 'my_custom_menu_item');
function my_custom_menu_item($items)
{
    if(is_user_logged_in())
    {
        $user=wp_get_current_user();
        $name=$user->display_name; // or user_login , user_firstname, user_lastname
        $items .= '
Welcome '.$name.'
';
    }
    return $items;
}

But now the “Welcome xy” is in all menus, how can i refere only to the topbarmenu?

Thanks,
Felix
