现在正在尝试此查询3天。我在这里有一个行列表：http://prntscr.com/dick00。我想要的是分别编辑和删除每一行。由于某种原因，id没有结转，没有记录正在更新。
当我点击access.php中的编辑时，我在地址栏中显示edit_access.php?id=。
以下是 access.php
中的链接 <td><a href="edit_access.php?id=<?php echo $row['id']; ?>"><i class="fa fa-edit"></i>edit</td>
edit_access.php 编辑1：php代码
<?php
// start session
session_start();

require_once('include/connection.php');
// set user session variables
$userId = $_SESSION['user_id'];
$error = [] ;
if(isset($_POST['update']))
{
$id = $_POST['id'];
$firstname = $_POST['firstname'];

感谢大家要求提供更多代码...我希望已经提供了足够的代码示例。
答案 0 :(得分：0)
你最喜欢把你的id放在html表单中的隐藏输入中，如下所示：
<input type="hidden" name="itemId" value="<?php echo '$_GET['id']'?>">
然后当您提交表单时，您在 $ _ POST ['itemId'] 变量中有 itemId 。
编辑： 我必须为你描述一下情景。也许你明白了。 你有一个访问列表，每行都有这个标记：
<a href="access-form.php?id=<?php echo $_GET['id']?>">access ....</a>
<form method="post" action="edit-access.php">
.....
<input type="hidden" name="id" value="<?php echo $_GET['id']?>">
.....
</form>
echo $_POST['id'];
