Php Mysql查询清除一行而不是更新

我不知道为什么会这样，我在代码中回显了$sqll，它显示了所有正确的信息，但是当它返回到包含信息的页面时，它是空白的

这是剧本

<?php
include("header.php"); 
include("sidebar.php");

$memberon = $_GET['user'];
$getmember = mysql_query("SELECT * FROM accounts WHERE username='".$memberon."'");
$member = mysql_fetch_array($getmember);
?>       

    <h2>Edit User</h2>

另一方面，我知道mysql_query和类似的东西正在被弃用，我想指出的是，我没有写这篇文章，只是为客户机做了一些编辑，而这一部分恰好是后面的痛

---

另外，只有if$\u POST['pcheck']中的查询不起作用，if$\u POST['subm']的第一个查询工作正常。

首先，末尾有一个空字符串。这不痛，但也没用

您将页面重定向到edit.php？user=$memberon，但在收到POST请求时未设置$memberon。您可以选择GET或POST，但不能同时选择两者

我猜，你必须重定向到

edit.php?user=$username

---

两件事；这充满了SQL注入漏洞，mysql扩展已被弃用。使用PDO或MySQLiinstead@Phil在发表评论之前，请阅读我的全部文章，我已经知道这一点，但是客户付钱让我编辑而不是写，所以我现在正在添加内容。你确定所有的输入变量都设置正确吗？另外，您应该在标头调用之后退出，这样您就不会无意中执行它们下面的代码。@siride Yes它们设置正确，因为当我回显$sqll时，所有信息都是正确的。另外，它是唯一一个在if$\u POST['pcheck']中不起作用的查询，if$\u POST['subm']的第一个查询工作正常重定向工作正常，因为所有表单操作都是空的，所以它对url没有任何影响，因此$memberon保留在原位，以便它可以拉取它。@kira423我的意思是，当表单提交时，您可以获得所有$\u POST变量，但不能获得$\u get变量。然后你有了所有的表单值，但没有$memberon。这将产生edit.php？user=
