Only first row checked

My bugfix

function _custom_breadcrumbs_load_for_type($node) {
  $sql = "SELECT * FROM {custom_breadcrumb} WHERE node_type = '%s'";
  $result = db_query($sql, $node->type);
  while ($breadcrumb = db_fetch_object($result)) {
    if (!empty($breadcrumb->visibility_php)) {
      // Use PHP code to check the visibility.
      ob_start();
      //$result = eval(trim($breadcrumb->visibility_php)); commented by GROL 
      $visibility = eval(trim($breadcrumb->visibility_php));
      ob_end_clean();
      if ($visibility == TRUE) {
	      return $breadcrumb;
      }
    }
    else {
      return $breadcrumb;
    }
  }
}
