Code

function signature_forum_user_exception($uid = 0, $op) {
  static $cache = array();
  $settings = variable_get('signature_forum_settings', signature_forum_defaults());
  if (!isset($cache[$uid]) || !is_array($cache[$uid])) {
    $result = db_query("SELECT r.rid AS rid FROM {role} r INNER JOIN {users_roles} ur ON ur.rid = r.rid WHERE ur.uid = %d", $uid);
    $cache[$uid] = array();
    while ($role = db_fetch_object($result)) {
      $cache[$uid][$role->rid] = $role->rid;
    }
    if ($uid > 0) {
      $cache[$uid][DRUPAL_AUTHENTICATED_RID] = DRUPAL_AUTHENTICATED_RID;
    }
  }
  foreach ($cache[$uid] as $rid) {
    switch ($op) {
      case 'min_length':
        if ($settings['signature_forum_roles'][$rid] == $rid) {
          return TRUE;
        }
        break;
      case 'show_once':
        if ($settings['signature_forum_show_once_roles'][$rid] == $rid) {
          return TRUE;
        }
        break;
