可能重复：
Paypal Checkout Express empty cart problem

我有paypal expresscheckout的问题。我使用了集成向导https://www.paypal-labs.com/integrationwizard/ecpaypal/main.php中的代码，一切正常但是当我被重定向到paypal时，我希望在paypal的页面上有一个订单总结，例如总金额和描述类型，但在我的情况下它的空白（就像在这个屏幕上http://imageshack.us/photo/my-images/819/blankv.png/）我可以把我正在使用的代码片段放在：

                  // ==================================
                  // PayPal Express Checkout Module
                  // ==================================

                  //'------------------------------------
                  //' The paymentAmount is the total value of
                  //' the shopping cart, that was set
                  //' earlier in a session variable
                  //' by the shopping cart page
                  //'------------------------------------
                  $paymentAmount = $_SESSION["Payment_Amount"];

                  //'------------------------------------

                  $shipToStreet = $shipping_address[0]['street1'];
                  $shipToStreet2 = $shipping_address[0]['street2']; //Leave it blank if there is no value
                  $shipToCity = $shipping_address[0]['city'];
                  $shipToState = "Romania";
                  $shipToCountryCode = "RO"; // Please refer to the PayPal country codes in the API documentation
                  $shipToZip = $shipping_address[0]['zip'];

                  $ack = strtoupper($resArray["ACK"]);
                  if($ack=="SUCCESS" || $ack=="SUCCESSWITHWARNING")
                  {
                             //dump($resArray);
                             //die;
                             $token = urldecode($resArray["TOKEN"]);
                             $_SESSION['reshash']=$token;
                             RedirectToPayPal ( $token );
                  }

任何帮助都会得到真正的帮助，提前谢谢。

Answer 1

除了此处的其他评论之外，在从SetExpressCheckout获取响应后重定向到PayPal时，请务必使用未记录的“useraction”选项：

CMD = _express结账＆安培;？的 useraction =提交＆安培;标记=所述-返回令牌

Here's the PayPal forum reference to this parameter

Answer 2

在调用SetExpressCheckout之前，您需要将项目添加到nvp字符串。

以下额外参数添加两个产品：

        &L_PAYMENTREQUEST_0_NAME0=productname
        &L_PAYMENTREQUEST_0_NUMBER0=productcode
        &L_PAYMENTREQUEST_0_DESC0=product-description
        &L_PAYMENTREQUEST_0_AMT0=productamount
        &L_PAYMENTREQUEST_0_QTY0=product-unit-price
        &L_PAYMENTREQUEST_0_NAME1=productname
        &L_PAYMENTREQUEST_0_NUMBER1=productcode
        &L_PAYMENTREQUEST_0_DESC1=product-description
        &L_PAYMENTREQUEST_0_AMT1=productamount
        &L_PAYMENTREQUEST_0_QTY1=product-unit-price
