php - 将Paypal链式/并行付款与快速结账相集成

我已经为预订系统制作了一个Web应用程序，并使用paypal作为支付网关。使用Paypal Express Checkout，我可以付款，但是现在我想将自己作为服务提供者与受人尊敬的酒店之间的付款比例为5％：95％。如何使用php中的快速结帐来完成此操作？

Paypal.config

     $currency = '$'; //Currency sumbol or code APP-80W284485P519543T

     //paypal settings sandbox
     $PayPalMode            = 'sandbox'; // sandbox or live
     $PayPalApiUsername     = 'email'; //PayPal API Username
     $PayPalApiPassword     = '1400209342'; //Paypal API password
     $PayPalApiSignature    = 'AFcWxV21C7fd0v3bYYYRCpSSRl31AIicHs2L8N-aSaeIWzH3DX-kQJPv'; //Paypal API Signature
     $PayPalCurrencyCode    = 'USD'; //Paypal Currency Code
     $PayPalReturnURL       = returnURL; //Point to process.php page
     $PayPalCancelURL       = cancelURL; //Cancel URL if user clicks cancel

paypal.class

    class MyPayPal {

    public function PPHttpPost($methodName_, $nvpStr_, $PayPalApiUsername, $PayPalApiPassword, $PayPalApiSignature, $PayPalMode) {
        // Set up your API credentials, PayPal end point, and API version.
        $API_UserName = urlencode($PayPalApiUsername);
        $API_Password = urlencode($PayPalApiPassword);
        $API_Signature = urlencode($PayPalApiSignature);

        $paypalmode = ($PayPalMode=='sandbox') ? '.sandbox' : '';

        $API_Endpoint = "https://api-3t".$paypalmode.".paypal.com/nvp";
        $version = urlencode('109.0');

        // Set the curl parameters.
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $API_Endpoint);
        curl_setopt($ch, CURLOPT_VERBOSE, 1);

        // Turn off the server and peer verification (TrustManager Concept).
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);

        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_POST, 1);

        // Set the API operation, version, and API signature in the request.
        $nvpreq = "METHOD=$methodName_&VERSION=$version&PWD=$API_Password&USER=$API_UserName&SIGNATURE=$API_Signature$nvpStr_";

        // Set the request as a POST FIELD for curl.
        curl_setopt($ch, CURLOPT_POSTFIELDS, $nvpreq);

        // Get response from the server.
        $httpResponse = curl_exec($ch);

        if(!$httpResponse) {
            exit("$methodName_ failed: ".curl_error($ch).'('.curl_errno($ch).')');
        }

        // Extract the response details.
        $httpResponseAr = explode("&", $httpResponse);

        $httpParsedResponseAr = array();
        foreach ($httpResponseAr as $i => $value) {
            $tmpAr = explode("=", $value);
            if(sizeof($tmpAr) > 1) {
                $httpParsedResponseAr[$tmpAr[0]] = $tmpAr[1];
            }
        }

        if((0 == sizeof($httpParsedResponseAr)) || !array_key_exists('ACK', $httpParsedResponseAr)) {
            exit("Invalid HTTP Response for POST request($nvpreq) to $API_Endpoint.");
        }

    return $httpParsedResponseAr;
  }

 }

和贝宝付款方式

         $padata = '&METHOD=SetExpressCheckout' .
                    '&RETURNURL=' . urlencode($PayPalReturnURL) .
                    '&CANCELURL=' . urlencode($PayPalCancelURL) .
                    '&PAYMENTREQUEST_0_PAYMENTACTION=' . urlencode("SALE") .
                    $paypal_data .
                    '&NOSHIPPING=1' . //set 1 to hide buyer's shipping address, in-case products that does not require shipping
                    '&PAYMENTREQUEST_0_ITEMAMT=' . urlencode($ItemTotalPrice) .
                    '&PAYMENTREQUEST_0_SHIPPINGAMT=' . urlencode($ShippinCost) .
                    '&PAYMENTREQUEST_0_SHIPDISCAMT=' . urlencode($discount) .
                    '&PAYMENTREQUEST_0_AMT=' . urlencode($GrandTotal) .
                    '&PAYMENTREQUEST_0_CURRENCYCODE=' . urlencode($PayPalCurrencyCode) .
                    '&LOCALECODE=GB' . //PayPal pages to match the language on your website.
                    '&LOGOIMG=http://salyani.org/booking/contents/images/BookingBeta100PX.png' . //site logo
                    '&CARTBORDERCOLOR=FFFFFF' . //border color of cart
                    '&ALLOWNOTE=1';

最佳答案

您可以通过同时包含两次付款的主要和次要信息，使用Express Checkout进行并行付款。更多详细信息here

但是，您不能通过快速结帐进行链式付款。
您将需要查看adaptive payments。

您只需要在SEtexpress结帐请求中包括以下示例请求。

METHOD=SetExpressCheckout
RETURNURL=http://example.com/success.html
CANCELURL=http://example.com/canceled.html
VERSION=93
PAYMENTREQUEST_0_CURRENCYCODE=USD
PAYMENTREQUEST_0_AMT=250
PAYMENTREQUEST_0_ITEMAMT=225
PAYMENTREQUEST_0_TAXAMT=25
PAYMENTREQUEST_0_PAYMENTACTION=Order
PAYMENTREQUEST_0_DESC=Sunset Sail for Two
PAYMENTREQUEST_0_SELLERPAYPALACCOUNTID=[e-mail]
