The RealName module allows the admin to choose fields from the user profile that will be used to add a "realname" element (method) to a user object. Hook_user is used to automatically add this to any user object that is loaded.

Code

function realname_form_alter($form_id, &$form) {
  global $user;
  if (!user_access('use realname')) {
    return;
  }

  //  drupal_set_message($form_id);
  if (substr($form_id, -10) == '_node_form') {

    //    drupal_set_message(print_r($form, TRUE));
    foreach ($form as $name => $elements) {
      if (substr($name, 0, 6) == 'field_') {
        if (isset($form[$name]['uids'])) {
          $fields = content_fields();
          $field = $fields[$name];
          $options = _userreference_potential_references($field);
          foreach ($options as $uid => $optname) {
