Is there a way that my PHP code can generate an encrypted BuyNow button that also includes custom fields and also implements an IPN URL and redirect page?

推荐答案

您不必进行加密。简单地采取自定义变量，并且，除其他事项外，你可能需要摆​​在那里，加上价格和产品编号的哈希​​值，像这样：

You don't have to encrypt. Simply take the 'custom' variable, and, among other things you might need to put in there, add a hash of the price and product number, like so:

$sCustom .= '|' . md5($sSalt . $sProduct . $sPrice);

然后，当IPN被处理时，确保该哈希没有什么被接收回干扰。如果是，则块的事务。

Then, when the IPN is processed, ensure that this hash was not disturbed with what is received back. If it was, then block the transaction.
