Paypal IPN 如何获取当前会话
我想要将我之前的 $_SESSION['cart'] 获取到
IPN 代码 我使用。一切正常，脚本从 Paypal 获取了 $_POST 数据。
if (strcmp ($res, "VERIFIED") == 0) {
$subject = time();
$to = '[email protected]';
foreach ($_POST as $key => $value) {
$body .= "\n$key: $value";
}
mail($to, $subject, $body);
}
问题
if (strcmp ($res, "VERIFIED") == 0) {
// 1. How to get my previous $_SESSION['cart'] here?
// 2. When I call my $_SESSION['cart'] here not ouput will come & it's empty.
// 3. Or this code only to get $_POST data from Paypal website only?
}
I want to get my previous $_SESSION['cart'] to the Paypal IPN
Sample of IPN Code I use. Everything working fine and script got the $_POST data from Paypal.
if (strcmp ($res, "VERIFIED") == 0) {
$subject = time();
$to = '[email protected]';
foreach ($_POST as $key => $value) {
$body .= "\n$key: $value";
}
mail($to, $subject, $body);
}

您不能这样做，因为 IPN 是在您的结账流程之外收到通知的。它本质上是一个独立于网站订购/支付过程的后台操作。如果您需要访问该会话中的信息，则需要将其存储在数据库中，然后包含某种标识符，该标识符也会传递给 Paypal。电子邮件地址通常很好，但唯一的标记（例如某种哈希值）可能更好。然后，当 IPN 通知带有该标识符时，您可以从数据库中提取该信息并根据需要使用。
You can't because IPN is notified outside of your checkout process. It essentially is a background operation separate from the ordering/payment process of your website. If there is information in that session that you need to access you will need to store it in a database and then include some kind of identifier with it that is also passed to Paypal. Email addresses are usually good but a unique token, like a hash of some kind, is probably better. Then when the IPN notification comes in with that identifier you can pull that information out of the database and use as needed.
