问使用自定义colum而不是meta键过滤用户

EN

add_filter('pre_get_users', 'filter_users_by_job_role_section');

function filter_users_by_job_role_section($query)
{
 global $pagenow;
 if (is_admin() && 'users.php' == $pagenow) {
  // figure out which button was clicked. The $which in filter_by_job_role()
  $top = $_GET['job_role_top'];
  $bottom = $_GET['job_role_bottom'];
  if (!empty($top) OR !empty($bottom))
  {
   $section = !empty($top) ? $top : $bottom;

   // change the meta query based on which option was chosen
   $meta_query = array (array (
      'key' => 'membership_user_role',
      'value' => $section,
      'compare' => 'LIKE'
   ));

 $query->set('meta_query', $meta_query);

  }
 }
}
