php - 如何自动化 Paypal 付款

Question

我正在为我在学校的最终项目开发一个网站，在我的网站上您可以购买硬币来打开礼物，但我想自动付款。当客户完成付款后，他会被重定向到 success.php，我如何安排他在付款成功后自动在他的帐户中获得 X 数量的硬币？

抱歉，使用 SQL 将其更新为 PDO 或 mySQLi

喜欢:

if (payment_finished){
sql= UPDATE 'users' SET 'balance' = $boughtamount WHERE username = '$username'
}

我用这个按钮来支付 Paypal 。

根据您的 PayPal 配置，重定向时付款将具有特定状态(成功/失败/取消/错误)。您可以检索该状态(以及您的引用)以自动执行该过程。通常，当用户被“重定向”时，您将通过 POST 收到该数据。另一种选择是在用户被重定向后 Paypal 将数据发送到的钩子(Hook)。 为了了解如何获取这些数据，您应该阅读适合您在 PayPal 上的配置/方法的文档。
