我有一个条纹付款网站，可以在其中付款并启动保存到数据库的订阅计划，但是我想知道如何制作一个可以取消订阅的取消按钮。
在thank-you.php中，此处存在取消订阅按钮，在paymentProcess.php中，此处if(isset($_POST['cancel'])) {
$stmt = $conn->prepare("SELECT subscription_id FROM users WHERE id = :id");
$stmt->execute(['id' => $customer->id]);
$row = $stmt->fetch(PDO::FETCH_OBJ);
$sub = \Stripe\Subscription::retrieve($row->subscription_id);
$sub->cancel();
}是取消按钮的代码，但是单击后没有任何改变，并且条带日志也没有改变，我们被困在这里，有什么建议吗？
