Question

我试图通过单击复选框和按钮从SQL数据库中删除表行。我的PHP代码：

<?php 

$conn = mysqli_connect("localhost","root","","cms");
$view_posts = "SELECT * from editorial ";

$post_array = $conn->query($view_posts) or die($conn->error);


if(isset($_POST['delete'])){
    $del  = $_POST["all_id"];
    foreach ($del as $x) {
    $delete_qur = "DELETE from editorial where id='$x'";
    $conn->query($delete_qur);
    }
}?>

在该（相同文件）下还有更多代码可用于表格显示数据：

<body>
<form action="<?php htmlspecialchars($_SERVER['PHP_SELF']) ?>" method="post">
    <button class="button" name="delete">Delete</button>
    <button class="button" name="edit">Edit</button> 
</form>

<table border="1">
    <th>PostID</th>
    <th>Title</th>
    <th>Post</th>
    <th>Created</th>
    <th>Options</th>

    <?php while($row = $post_array->fetch_assoc()) : ?>
        <tr>
            <td><?php echo $row["id"]; ?></td>
            <td><?php echo $row["title"]; ?></td> 
            <td><?php echo $row["post"]; ?></td>
            <td><?php echo $row["created"]; ?></td>
            <td><form action="<?php htmlspecialchars($SERVER['PHP_SELF']);?>" method="post">
                <input type="checkbox" name="all_id[]" value="<?php echo $row['id']; ?>">
                </form>
            </td>
        </tr>
    <?php endwhile; ?>
</table>

我想要做的是让每一行都有自己的复选框。在单击复选框后，我可以删除或编辑该特定行。对不起，不好的编码习惯，PHP中的新功能。
