PayPal IPN 和 PDT - 无法在 return_url 页面或电子邮件中获取买家邮政地址

Question

我正在设置一个基本的捐赠系统，需要向客户发送一封确认电子邮件，但无法让买家的邮政地址显示在网站的 return_url 页面上，或显示在发送给客户的电子邮件中。纳税人的自定义值是/否单选选项不会在电子邮件中跟进。我在我们的网站上使用自定义表格，其中包含用于填写捐赠金额、姓名、地址以及他们是否纳税的字段(简单的 radio 选择。)不确定我是否使用正确，但我同时启用了 IPN 和 PDT 设置PayPal 帐户中的站点站点和设置。

捐赠表格:

目前我需要做的就是在电子邮件、return_url 页面和 PayPal 网站上显示的地址(目前显示邮寄地址:未指定。)

Answer 1

您在测试时输入地址吗？尝试传递变量“no_shipping”并将值设置为“2”，看看这是否有所不同。此外，PayPal 不会传回不是有效 PayPal 变量的变量/值，这意味着您将无法构建自己的变量并传递它们。
