Php 从html表内部集成DB info以将单行信息输出到另一个页面

我正在创建一个管理部分，以便能够更新用户信息。我有一个通过while循环构造的表，该表显示了我调用的所有用户信息。然后，我添加了一个编辑选项，并创建了一个customeredit.php页面，我将在其中创建输入字段，我可以在其中键入更改并提交

我的问题是，我如何编程我的代码，当单击单行中的编辑按钮时，它会识别该行ID并将其与记录关联

我没有为customeredit.php文件附加任何代码，因为它只有基本格式。我是否需要在customeredit.php文件中插入任何内容来实现此功能

<?php
$con = mysqli_connect("localhost","root","","bfb");
$q = mysqli_query($con,"SELECT * FROM users");
?>                 
<table class="tableproduct">
    <tr>
        <th class="thproduct">ID</th>
        <th class="thproduct">First Name</th>
        <th class="thproduct">Last Name</th>
        <th class="thproduct">Email</th>
        <th class="thproduct">Username</th>
        <th class="thproduct">Group</th>
    </tr>   
<?php while($row = mysqli_fetch_assoc($q)) : ?>
    <tr>
        <td class="tdproduct"><?php echo $row['id']; ?> </td>
        <td class="tdproduct"><?php echo $row['firstname']; ?> </td> 
        <td class="tdproduct"><?php echo $row['lastname']; ?> </td>
        <td class="tdproduct"><?php echo $row['email']; ?> </td>
        <td class="tdproduct"><?php echo $row['username']; ?> </td>
        <td class="tdproduct"><?php echo $row['group']; ?> </td>
        <td class="tdproduct">
             <a href='editusers.phpid'='<?php echo $row['id']; ?>'>EDIT</a>
        </td>
    </tr>
<?php endwhile; ?>
</table>

<?php
require_once 'core/init.php';

$user = new User();

 if(Session::exists('home')) {
echo '<p>' . Session::flash('home') . '</p>';
 }
if(!$user->isLoggedIn()) {

                    </form>

 <?php
     $_GET['id'];

我将在edituser.php中输入的一些输入字段

<?php
require_once 'core/init.php';

$user = new User();

 if(Session::exists('home')) {
echo '<p>' . Session::flash('home') . '</p>';
 }
if(!$user->isLoggedIn()) {
Redirect::to('index.php');

                            <input type="text" name="firstname"  class="inputbar" value="<?php echo escape($user->data()->firstname); ?>" required>
                        </div>
                        <div class="field">
                            <label for="lastname">Last name</label>

<?php

您可以添加输入文本字段以显示从数据库检索的数据

而不是$row['rowname']

你可以加上

<input type="text" name="product_<?php echo $product_id;?>" value="<?php echo $row['rowname'];?>">

并使用post方法发送到服务器。

将编辑链接行更改为

---

在.php之后缺少问号将导致语法错误。当您进入editusers.php页面时，您可以使用$\u GETid

所以我要做的就是进入customeredit.php文件并键入echo代码？这适用于我点击编辑的任何唱片吗？理想情况下，我希望能够识别所选id，而不仅仅是从该表输出信息。我将把输入字段，从数据库内回声信息。然后允许更新信息。这不是在做什么吗？我是否需要在GET语句中添加任何内容？它只需添加$_GETid；，即可识别所有内容？您将使用它从数据库中获取特定用户，如select*from users where ID=
