1.找到include/controller/comment_controller.php 2.在评论判断语句中添加昵称限制代码

    elseif (ROLE == ROLE_VISITOR && Option::get('comment_needchinese') == 'y' && !preg_match('/[\x{4e00}-\x{9fa5}]/iu', $name)) {
   emMsg('评论失败：昵称存在敏感词汇');
        }

3.添加邮箱限制代码

         elseif (empty($mail)){
            emMsg('评论失败：请填写邮箱');
  }
