当用户点击发表评论＆＃39;在评论前面链接，相应的评论存储在数据库表中 在此处，它检查注释编号是否已存在于数据库表中。 我的问题是，当我点击发表评论＆＃39;链接，禁用所有编辑链接。 我想要的是只禁用特定的编辑＆＃39;链接，评论在数据库中。

     if($com_no=$new_com_no)
   {
        $com_no=$row['com_no'];
        echo"<a class='btn btn-small btn-info'  disabled>Edit</a>";
    }
   else{
      $com_no=$row['com_no'];
     echo"<a href='member.php?uname=$uname&ino=$ino&cid=$cid&com_no=$com_no&comment=$comment&op_type=EditComment' class='btn btn-small btn-info'>Edit</a>";
   }


     $com_no=$row['com_no'];

     echo"</td>
     <td><a href='member.php?uname=$uname&com_no=$com_no&ino=$ino&cid=$cid&title=$title&comment=$comment&op_type=PostComment' class='btn btn-small btn-warning'>Post Comment</a>
