Question

<?php
require_once 'config.php';
session_start();
$result = mysqli_query($link, "SELECT * FROM images where allowance=0 order by id desc");

while ($row = mysqli_fetch_array($result)) {
        ?>
            <div id='img_div'>
            <p><?php echo $row['image_text']; ?></p>
            <img src="images/<?php echo $row['image']; ?>" >
            <br><br>
            <a role="button" class="btn btn-outline-success app" name="publish" href='admin.php?publish=true'>Publish</a>&nbsp;
            <a role="button" class="btn btn-outline-danger app" name="reject"  href='admin.php?reject=true'>Reject</a>
            </div>

        <?php   
    }
    ?>
<?php
            if (isset($_GET['publish'])) {
                $test=$_GET['id'];
                $sql1 = "UPDATE images SET allowance='1' where id=$test"; 

                if (mysqli_query($link, $sql1)) {
                    echo "Record updated successfully";
                } else {
                    echo "Error updating record: " . mysqli_error($link);
                }
                }
                ?>

我在这里要做的是我是管理员。当用户上传照片时，它将具有允许值为＆＃39; 0＆＃39;。

click here to see my mysql table with allowance value as 0

它不会在时间轴上显示。我将通过管理员登录。因此，当我单击发布时，允许值更新为1，因此它将在时间轴中显示。

这里的问题是，当我使用此代码时，所有图像都会更新为值1.

click here to see my mysql table with allowance value as 0

我找不到mysql命令的特定WHERE条件来更新我的允许值..

还是有人为这个概念有任何代码.. 即，用户上传照片，它将存储在数据库中，然后在管理员批准后，它将在时间轴中显示...

提前致谢...

<?php
require_once 'config.php';
session_start();
if (isset($_GET['publish'])) {
    $test=$_GET['id'];
    $sql1 = "UPDATE images SET allowance='1' where id=$test"; 

    if (mysqli_query($link, $sql1)) {
        echo "Record updated successfully";
    } else {
        echo "Error updating record: " . mysqli_error($link);
    }
}

$result = mysqli_query($link, "SELECT * FROM images where allowance=0 order by id desc");

while ($row = mysqli_fetch_array($result)) { ?>
    <div id='img_div'>
        <p><?php echo $row['image_text']; ?></p>
        <img src="images/<?php echo $row['image']; ?>" >
        <br><br>
        <a role="button" class="btn btn-outline-success app" name="publish" href='admin.php?publish=true&id=<?php echo $row['id']; ?>'>Publish</a>&nbsp;
        <a role="button" class="btn btn-outline-danger app" name="reject"  href='admin.php?reject=true'>Reject</a>
    </div>
<?php } ?>
