本人刚开始学php，学写代码做留言板，谁帮我看一下为什么写出来的页面中没有“回复”和“删除”的选项？？？

------解决思路----------------------
太长，没认真看
<?php if(Authority::check_delete()==true){?>
<a href="<?php echo $row["id"];?>" class="reply_button">回复</a>
<a href="indexy.php?type=delete&id=<?php echo $row["id"];?>">删除</a>
<?php }?>
应该是Authority::check_delete()=false，所以下面没有执行，当然没有回复和删除了
------解决思路----------------------
那块有权限验证，应该是库中你当前用户没有这两个操作的权限
------解决思路----------------------
缓存 ！！删除了 还有 不可能吧！！！
------解决思路----------------------
不是要你清空回收站，是删除浏览器缓存。。。
