Php 贝宝确认了哪笔付款？

更新2:

我目前拥有的代码如下：

paypelplatform.php：

basic_payment.php：（在 （以下链接）

php：（ipn侦听器）

如果上面第二个链接中的框为空，只需单击“重新开始”，然后单击“下一步”，直到进入步骤4，或者单击此处：

我想这是启动付款的代码，我需要在这里指定自定义值吗？如果是，怎么做

当paypal使用其ipn系统确认付款时，我将返回以下值：

[responseEnvelope.ack] => Success

[responseEnvelope.build] => 1822511 
[payKey] => AP-8AW04791DK417062F 
[paymentExecStatus] => CREATED )

我看不到任何允许我建立连接的值，允许我更新正确的数据库记录，以表明付款已成功完成。

txn_id=3848811是来自paypal的交易id。如果您希望paypal发回对您系统中某个标识符（您的支付标识符）的引用，您可以使用“自定义”字段，您将首先在请求中发送该字段

---

如果您使用NVP，它将是PAYMENTREQUEST\u n\u CUSTOM，不知道SOAP接口。

我不明白，在paypals基本支付模块脚本中，如何捕获txn\u id？如果我能捕捉到这一点，那么我就会看到如何使用从ipn返回的txn_id来更新正确的数据库记录。您重定向了客户，对吗？交易ID仅在客户完成付款时生成，这意味着您只能在返回请求（即成功URL）中或通过IPN捕获交易ID。因此，您应该发送一个自定义字段来识别购物车和实际支付的款项。是的，这将在CallPay（）函数中进行，您需要检查文档。@jishi，我一直在看文档，结果很头痛。CallPay（）函数发送trackingid，ipn是否返回相同的trackingid？在ipn示例中，您收到“custom=xyz123”，您在哪里设置的？在此调用中，Paypal返回我“内部服务器错误。请查看服务器日志了解详细信息”错误。我不明白问题出在哪里。我检查了服务器日志，但没有找到与此错误有关的任何内容。有什么建议吗？
