Question

我正在尝试从我的简单电子商务网站中删除用户，以处理我正在处理的项目。当我单击删除按钮时，将显示该消息，并告诉我它正确删除了表中的数据。但是当我进入我的sql数据库并检查数据时，它仍然存在。我无法弄清楚我做错了什么或我的错误在哪里。任何帮助，将不胜感激。我的代码如下。

 <?php 
session_start();
if (isset($_SESSION['shirt_users_id']) && isset($_SESSION['full_name'])) {
require('mysql_connect.php');

if (isset($_GET['shirt_users_id'])) {
    $shirt_users_id = $_GET['shirt_users_id'];

另外，我知道我的代码不是最有效的方式来做事情，但我是整个html / css / php场景的新手，我正在尽我所能所以请不要给我一些关于不同的方法请这样做！
