paypal - PayPal IPN，如何从下拉菜单中选择价格

Question

PayPal 按钮可以有下拉菜单，例如：

• 选项 1 - 5 美元
• 选项 2 - 10 美元
• 选项 3 - 15 美元

当我通过 IDN 处理付款时，我将如何获得用户选择的选项？我不确定我是否只能根据支付的价格来做，因为税/费用/货币可能会改变。PayPal 是否以某种方式传递选定的价值？

贝宝可以。您为什么不在https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_button-designer&button_type=buynow创建一个带有下拉菜单的实际沙盒按钮并使用它进行测试，以便您查看实际此类按钮的 IPN？

如果您希望将 IPN 发送到该帐户的个人资料 URL 中的那个，您需要先登录 www.sandbox.paypal.com 上的沙盒业务帐户。或者，在按钮的高级变量中，您可以设置notify_url=为您的 IPN 侦听器。
