Paypal IPN 有效,但不更新数据库。不确定如何调试
Paypal IPN works, but doesn't update database. Unsure on how to debug
经过多年的努力,我终于设法从 Paypal 获得了我的 IPN。我在 GITHUB 上找到了一个代码,它提供了一个 ipn.log,它返回 "Verified" 或 "Invalid"。
使用 Paypal 沙盒后,交易有效,我的 ipn.log 文件更新告诉我它已通过验证。
但是我在这之后输入的代码不起作用,我完全不知道如何修复它!

我完全不知所措,脑子一片空白!请理解我的 php 编码水平很基础!
感谢您的所有帮助!
您正在使用变量 $mc_gross
,但您没有从 $_POST
数据中获取它,我不明白您应该如何获得实际数量?
如果您愿意 $mc_gross = $_POST['mc_gross'];
,您实际上会得到您想要的价格!
