WordPress’ get_super_admins() function can be used to get the logins for all the users on the current site. Its return value is in array that looks like: [ 'maryann123', 'johnsmith456', 'annie-mcarthur' ]. If you want WP_User objects for each of those users though, you can use the get_users() function and pass in get_super_admins() as the login__in argument, like this:
| <?php | |
| /** | |
| * Get all Super Admin users on the current site. | |
| * | |
| * @return array WP_User objects. | |
| */ | |
| function get_all_superadmin_users() { | |
| return get_users([ | |
| 'login__in' => get_super_admins() | |
| ]); | |
| } |
Get Non-Super Admins
If you want to do the opposite and get all non-Super Admins, you can use login__not_in instead, like this:
| <?php | |
| /** | |
| * Get all non-Super Admin users on the current site. | |
| * | |
| * @return array WP_User objects. | |
| */ | |
| function get_all_non_superadmin_users() { | |
| return get_users([ | |
| 'login__not_in' => get_super_admins() | |
| ]); | |
| } |
