PHPで掲示板のコードを書く方法についてアドバイスをお願いします。

求教，关于php写留言板代码
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？？？

-----ソリューションのアイデア----- ------------------
長すぎてよく読んでません

<br /><?php if(Authority::check_delete()==true){?><br />  <a href="<?php echo $row["id"];?>" class="reply_button">回复</a>  <br />  <a href="indexy.php?type=delete&amp;id=<?php echo $row["id"];?>">删除</a><br />  <?php }?><br />

のはずですAuthority::check_delete()= false なので以下は実行されず、当然返信も削除もありません
-----解決案----------- -----------

引用:

管理者ログインおよび「削除」「返信」機能に問題があります。実装することはできません。データベース接続に問題があるのでしょうか? ? ?

そのブロックには権限検証があります。ライブラリ内の現在のユーザーにはこれら 2 つの操作に対する権限がないはずです
-----解決策のアイデア--- ---- ---------------
キャッシュ！ ！やはり削除は無理ですね！ ！ ！
------ソリューションのアイデア----------------------

本当です、なぜですか？完全に削除され、ゴミ箱も空になりました。 。 。

ごみ箱を空にするように要求されるわけではなく、ブラウザのキャッシュが削除されるだけです。 。 。
