drupal 的aggregator无法加入feed

这是本人目前对主程序的唯一一个修改
将 drupal/modules/aggregator/aggregator.module中的/** xx */部分修改为下面的部分
/**db_query("INSERT INTO {aggregator_feed} (fid, title, url, refresh, block) VALUES (%d, '%s', '%s', %d, 5)", $edit['fid'], $edit['title'], $edit['url'], $edit['refresh']);*/
 db_query("INSERT INTO {aggregator_feed} (fid, title, url, refresh, description, image, block) VALUES (%d, '%s', '%s', %d, '', '', 5)", $edit['fid'], $edit['title'], $edit['url'], $edit['refresh']);
