【问题描述】：
我正在开发一个简单的用户配置文件，用户可以在其中通过 Mysql 更新一些数据。但它不会更新任何东西。为什么？
<?php
if (isset($_GET['pageID'])) {
$id = $_GET['pageID'];
include("connector.php");
$stmt = $conn->prepare(" SELECT
cl.clientID, cl.firstname, cl.lastname, cl.mobilephone, cl.phone, cl.client_ID,
ad.street, ad.city, ad.postalcode,
wo.work_ID,
ha.hardware1, ha.serialnumber, ha.hardware2, ha.serialnumber2
FROM client cl
JOIN adress ad ON cl.clientID = ad.clientID
LEFT JOIN work wo ON cl.clientID = wo.clientID
LEFT JOIN hardware ha ON ad.adressID = ha.adressID
WHERE cl.clientID = '$id'");
$stmt->execute();
}
?>
<?php while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) : ?>

<?php endwhile; ?>如您所见，有一个while-loop 来获取数据并将它们显示到某些字段中。在此循环之间，我创建了两个Bootstrap-Modals，用户可以在其中编辑某些内容。如果用户单击“保存”按钮，则不会发生任何事情。我真的不明白问题出在哪里。
还有一点：用户配置文件是使用 clientID(pageID) 动态生成的。我如何临时保存这个pageID，这样我可以在表单操作method ="POST"后返回当前页面@
clientID 是数据库中clients.client 表的主键。 client_ID 是用户必须自己设置的ID，他可以设置任何他想要的。 PageID 链接到 clientID 用于生成动态页面。这意味着：在另一个页面上有一个表格，其中显示了有关所有用户的一些基本信息。如果登录的用户点击表中的用户，则会动态生成用户配置文件。
【问题讨论】：
-
从 url 中移除 pageID=1
-
不要将更新逻辑放入循环人
-
如果你点击保存，你的页面会刷新吗？
-
别抱歉，只是纠正错误，尤其是缺少大写字母。
-
@Christoph，您可以将 pageID 存储在隐藏字段中，并在表单提交时发布
