我确实从我的同一个问题尝试了一些解决方案,但没有工作。我打赌这完全在我的代码中。我正在尝试将它们放在每个已经循环的表中,它起作用我能够在每个表上得到一个按钮,但我不能让它们工作。这是我的代码
<?php
$con = new PDO('mysql:host=localhost; dbname=library_member', $username = 'root', $password = '');
$q = "SELECT * FROM user_list";
$stmt = $con->prepare($q);
$stmt -> execute();
?>
<table border="1">
<td>ID</td>
<td>Firstname</td>
<td>Lastname</td>
<td>Address</td>
<td>Contact</td>
<td>Email</td>
<?php while ($row = $stmt->fetch(PDO::FETCH_ASSOC)){?>
<tr>
<td><?php echo $row['id']; ?></td>
<td><?php echo $row['firstname']; ?></td>
<td><?php echo $row['lastname']; ?></td>
<td><?php echo $row['address']; ?></td>
<td><?php echo $row['contact']; ?></td>
<td><?php echo $row['email']; ?></td>
<td><button><a href='library-delete.php?id=$id/'>Delete</a></button></td>
</tr>
<?php } ?>
</table>
这是删除发生的代码。
<?php
$con = new PDO('mysql:host=localhost; dbname=library_member', $username = 'root', $password = '');
$q = "DELETE FROM user_list WHERE id = :id";
$stmt = $con->prepare($q);
$stmt->bindParam( ':id' , $_GET['id'], PDO::PARAM_INT);
$stmt->execute();
echo "<script type='text/javascript'>
alert('Information have been deleted.');
window.location='library-showlist.php';
</script>";
?>
它会直接发送给我提示部分。我的输入数据都没有被删除。

尝试更改您的代码:
library-delete.php?id=<?php echo $row['id']?>
