使用此脚本如何获得订单总数。

我需要使用Payal Express Checkout支付Paypal定期付款的脚本。我还需要更新并取消定期付款。

答案 0 :(得分：0)

要发布succsessifuly您的代码，必须设置一些额外的参数。如果比较两个例子，我还会清除你会发现的一些其他错误。主要的是：

  1. $returnURL和$cancelURL必须是真实的网址且没有方法urlencode()
  2. $version必须设置为urlencode('124.0');
  3. SetExpressCheckout的参数必须如示例中那样设置。

  4. 我建议直播测试，只需在$0.01

    中设置价格即可

    请按照以下示例：
