Question

首先：据我所知，目前还没有YouTube视频或教程。我找到了一些，但它们是JavaScript，但我不知道它，所以我不能在很短的时间内完成。

我最近发布了同样的问题但是根据一些人的建议改变了我的代码。我遇到了很多错误而不是解决方案......

无论如何，我有一张我的网站图片和我想做的事情。

最后我的代码在下面，我删除了非常必要的HTML部分。

adduser.php：

    <?php
    session_start();
        if (!isset($_SESSION['username']))
        {
            header('location: login.php');
        die();
        }


    ?>

                        href="archive.php?user_id=<?= $user_id?>&status=<?=$status?>">

                        <?php if ($row['user_status']=='Disable')   
                        echo "Unarchive"; 
                        if ($row['user_status']=='Enable')

    </body>

这是我的Archive.php：

    <?php
    require ("config.php");

    $user_id= $_GET['user_id'];
    $user_status = $_GET['user_id'];

    $query = $db->prepare ("SELECT * FROM users WHERE user_id = :user_id, user_status = :user_status");

    $query->bindParam(':user_id', $user_id);
    $query->bindParam(':user_status',$user_status);
    $query->execute();

    if ($user_status=='Enable')
    {
        $sql = "UPDATE users SET user_status = 'Disable' WHERE user_id = :user_id";
    }
    if ($user_status=='Disable')
    {
        $sql = "UPDATE users SET user_status='Enable' WHERE user_id = :user_id";
    }

    if ($query->execute([':user_status'=>$user_status, ':user_id'=>$user_id])){

        header("Location:adduser.php");
    }
    ?>

首先，您需要清除语句并将参数分开，如下所示。

第1步：

参数是（查询字符串），以?开头，更多参数后面跟&

<?php
$user_id = $row['user_id'];
$status = '';
if ($row['user_status'] == 'Enable') {
    $status = 'Enable';
} else if ($row['user_status'] == 'Disable') {
    $status = 'Disable';
}
?>
<a href="archive.php?user_id=<?=$user_id?>&user_status=<?=$status?>">

如果您的$row['user_status']值始终与条件语句相同，则您不需要条件只需按照赋值变量。

<?php
$user_id = $row['user_id'];
$status = $row['user_status'];
?>
<a href="archive.php?user_id=<?=$user_id?>&status=<?=$status?>">

第2步： 那么这个

$id= $_GET['user_id'];

到

$user_id= $_GET['user_id'];
$user_status = $_GET['user_status'];

因为您的绑定参数采用未在Archive.php

中定义的变量

$query->bindParam(':user_id', $user_id);
$query->bindParam(':user_status',$user_status);

编辑2：

改变你的`从

开始的地方

<td>
<?php
$user_id = $row['user_id'];
$status = $row['user_status'];

只需替换为以下内容。

<td>
    <?php
    $user_id = $row['user_id'];
    $status = $row['user_status'];
    $btn_confirm = '';
    if ($status == 'Enable') {
        $btn_confirm = "disable";
    } else if ($status == 'Disable') {
        $btn_confirm = "enable";
    }
    ?>
    <a class="archive" onclick="return confirm('Are you sure you want to <?= $btn_confirm; ?> this user account?')"
       href="Archive.php?user_id=<?= $user_id ?>&status=<?= $status ?>">
        <?php if ($status == 'Disable') {
            echo "Unarchive";
        } else if ($status == 'Enable') {
            echo "Archive"; }
        ?>

    </a>
</td>

注意：您的文件名为Archive.php而非archive.php这会导致空白页面出现问题

我希望我的按钮更改状态设置，但不是更改它，而是转到href页面
