Paypal快递结账多项

我正在尝试将多个项目放入Express Checkout。我尝试了所有类型的更改，但只有第一项（'产品名称1'）出现在paypal中，金额为35 $。如何修复此问题以处理多个项目？代码是这样的：

<form action="paypal_ec_redirect.php" method="POST">
<input type="hidden" name="L_PAYMENTREQUEST_0_NAME0" value="product name 1"></input>
<input type="hidden" name="L_PAYMENTREQUEST_0_DESC0" value="this is the product description"></input>
<input type="hidden" name="L_PAYMENTREQUEST_0_AMT0" value="10.00"></input>
<input type="hidden" name="L_PAYMENTREQUEST_0_NUMBER0" value="1"></input>
<input type="hidden" name="L_PAYMENTREQUEST_0_QTY0" value="1"></input>

<input type="hidden" name="L_PAYMENTREQUEST_0_NAME1" value="product name 2"></input>
<input type="hidden" name="L_PAYMENTREQUEST_0_DESC1" value="this is the product description"></input>
<input type="hidden" name="L_PAYMENTREQUEST_0_AMT1" value="25.00"></input>
<input type="hidden" name="L_PAYMENTREQUEST_0_NUMBER1" value="2"></input>
<input type="hidden" name="L_PAYMENTREQUEST_0_QTY1" value="1"></input>

<input type="hidden" name="PAYMENTREQUEST_0_ITEMAMT" value="35.00"></input>
<input type="hidden" name="PAYMENTREQUEST_0_AMT" value="35.00"></input>
<input type="hidden" name="currencyCodeType" value="USD"></input>
<input type="hidden" name="paymentType" value="Sale"></input>

我遇到了同样的问题。

他们在演示中的代码只在paypal_functions.php文件的CallShortcutExpressCheckout函数中手动检查带有 isset（）的项目，并且它还将它检查的单个项目的总和更改为paypal_ec_redirect.php中所有项目的总和，这就是为什么它出现在您的PayPal中，其中显示的一个项目金额为35 $。

您可以在CallShortcutExpressCheckout函数中更改其代码，以使用foreach循环遍历post数据，而不是手动检查其预定参数上的isset（）。

您还需要注释掉它将产品项目金额的值更改为所有产品的总金额。

更改paypal_functions.php函数中的 CallShortcutExpressCheckout ：

CellValue cellValue = evaluator.evaluate(cell);
int cellValueType = cellValue.getCellType();
if(cellValueType == Cell.CELL_TYPE_NUMERIC){
    if(myIsADateFormat(cell){
        ....
    }
}

到此：

function CallShortcutExpressCheckout( $paramsArray, $returnURL, $cancelURL) 
{
    //------------------------------------------------------------------------------------------------------------------------------------
    // Construct the parameter string that describes the SetExpressCheckout API call in the shortcut implementation
    // For more information on the customizing the parameters passed refer: https://developer.paypal.com/docs/classic/express-checkout/integration-guide/ECCustomizing/

    //Mandatory parameters for SetExpressCheckout API call
    if(isset($paramsArray["PAYMENTREQUEST_0_AMT"])){
        $nvpstr = "&PAYMENTREQUEST_0_AMT=". $paramsArray["PAYMENTREQUEST_0_AMT"];
        $_SESSION["Payment_Amount"]= $paramsArray["PAYMENTREQUEST_0_AMT"];
    }

    if(isset($paramsArray["paymentType"])){
        $nvpstr = $nvpstr . "&PAYMENTREQUEST_0_PAYMENTACTION=" .  $paramsArray["paymentType"];
        $_SESSION["PaymentType"] = $paramsArray["paymentType"];
    }

    if(isset($returnURL))
    $nvpstr = $nvpstr . "&RETURNURL=" . $returnURL;

    if(isset($cancelURL))
    $nvpstr = $nvpstr . "&CANCELURL=" . $cancelURL;

    //Optional parameters for SetExpressCheckout API call
    if(isset($paramsArray["currencyCodeType"])) {
        $nvpstr = $nvpstr . "&PAYMENTREQUEST_0_CURRENCYCODE=" . $paramsArray["currencyCodeType"];
        $_SESSION["currencyCodeType"] = $paramsArray["currencyCodeType"];   
    } 

    if(isset($paramsArray["PAYMENTREQUEST_0_ITEMAMT"])){
        $nvpstr = $nvpstr . "&PAYMENTREQUEST_0_ITEMAMT=" . $paramsArray["PAYMENTREQUEST_0_ITEMAMT"];
        $_SESSION['itemAmt']= $paramsArray["PAYMENTREQUEST_0_ITEMAMT"];
    }

    if(isset($paramsArray["PAYMENTREQUEST_0_TAXAMT"])){
        $nvpstr = $nvpstr . "&PAYMENTREQUEST_0_TAXAMT=" . $paramsArray["PAYMENTREQUEST_0_TAXAMT"];
        $_SESSION['taxAmt']= $paramsArray["PAYMENTREQUEST_0_TAXAMT"];
    }

    if(isset($paramsArray["PAYMENTREQUEST_0_SHIPPINGAMT"])){
        $nvpstr = $nvpstr . "&PAYMENTREQUEST_0_SHIPPINGAMT=" . $paramsArray["PAYMENTREQUEST_0_SHIPPINGAMT"];
        $_SESSION['shippingAmt'] = $paramsArray["PAYMENTREQUEST_0_SHIPPINGAMT"];
    }

    if(isset($paramsArray["PAYMENTREQUEST_0_HANDLINGAMT"])){
        $nvpstr = $nvpstr . "&PAYMENTREQUEST_0_HANDLINGAMT=" . $paramsArray["PAYMENTREQUEST_0_HANDLINGAMT"];
        $_SESSION['handlingAmt'] = $paramsArray["PAYMENTREQUEST_0_HANDLINGAMT"];
    }

    if(isset($paramsArray["PAYMENTREQUEST_0_SHIPDISCAMT"])){
        $nvpstr = $nvpstr . "&PAYMENTREQUEST_0_SHIPDISCAMT=" . $paramsArray["PAYMENTREQUEST_0_SHIPDISCAMT"];
        $_SESSION['shippingDiscAmt'] = $paramsArray["PAYMENTREQUEST_0_SHIPDISCAMT"];
    }

    if(isset($paramsArray["PAYMENTREQUEST_0_INSURANCEAMT"])){
        $nvpstr = $nvpstr . "&PAYMENTREQUEST_0_INSURANCEAMT=" . $paramsArray["PAYMENTREQUEST_0_INSURANCEAMT"];
        $_SESSION['insuranceAmt'] = $paramsArray["PAYMENTREQUEST_0_INSURANCEAMT"];
    }

    if(isset($paramsArray["L_PAYMENTREQUEST_0_NAME0"]))
    $nvpstr = $nvpstr . "&L_PAYMENTREQUEST_0_NAME0=" . $paramsArray["L_PAYMENTREQUEST_0_NAME0"];

    if(isset($paramsArray["L_PAYMENTREQUEST_0_NUMBER0"]))
    $nvpstr = $nvpstr . "&L_PAYMENTREQUEST_0_NUMBER0=" . $paramsArray["L_PAYMENTREQUEST_0_NUMBER0"];

    if(isset($paramsArray["L_PAYMENTREQUEST_0_DESC0"]))
    $nvpstr = $nvpstr . "&L_PAYMENTREQUEST_0_DESC0=" . $paramsArray["L_PAYMENTREQUEST_0_DESC0"];

    if(isset($paramsArray["L_PAYMENTREQUEST_0_AMT0"]))
    $nvpstr = $nvpstr . "&L_PAYMENTREQUEST_0_AMT0=" . $paramsArray["L_PAYMENTREQUEST_0_AMT0"];

    if(isset($paramsArray["L_PAYMENTREQUEST_0_QTY0"]))
    $nvpstr = $nvpstr . "&L_PAYMENTREQUEST_0_QTY0=" . $paramsArray["L_PAYMENTREQUEST_0_QTY0"];

    if(isset($paramsArray["LOGOIMG"]))
    $nvpstr = $nvpstr . "&LOGOIMG=". $paramsArray["LOGOIMG"];

    /*
    * Make the API call to PayPal
    * If the API call succeded, then redirect the buyer to PayPal to begin to authorize payment.  
    * If an error occured, show the resulting errors
    */
    $resArray=hash_call("SetExpressCheckout", $nvpstr); 
    $ack = strtoupper($resArray["ACK"]);
    if($ack=="SUCCESS" || $ack=="SUCCESSWITHWARNING")
    {
        $token = urldecode($resArray["TOKEN"]);
        $_SESSION['TOKEN']=$token;
    }
    return $resArray;
}

然后在paypal_ec_redirect.php上注释掉这一行：

function CallShortcutExpressCheckout( $paramsArray, $returnURL, $cancelURL) 
{
    //------------------------------------------------------------------------------------------------------------------------------------
    // Construct the parameter string that describes the SetExpressCheckout API call in the shortcut implementation
    // For more information on the customizing the parameters passed refer: https://developer.paypal.com/docs/classic/express-checkout/integration-guide/ECCustomizing/

    //Mandatory parameters for SetExpressCheckout API call

    if(isset($returnURL))
    $nvpstr = $nvpstr . "&RETURNURL=" . $returnURL;

    if(isset($cancelURL))
    $nvpstr = $nvpstr . "&CANCELURL=" . $cancelURL;

    foreach ($paramsArray as $k => $value){
        $nvpstr = $nvpstr . "&" . $k . "=" . $value;
    }

    /*
    * Make the API call to PayPal
    * If the API call succeded, then redirect the buyer to PayPal to begin to authorize payment.  
    * If an error occured, show the resulting errors
    */
    $resArray=hash_call("SetExpressCheckout", $nvpstr); 
    $ack = strtoupper($resArray["ACK"]);
    if($ack=="SUCCESS" || $ack=="SUCCESSWITHWARNING")
    {
        $token = urldecode($resArray["TOKEN"]);
        $_SESSION['TOKEN']=$token;
    }
    return $resArray;
}

迟到的答案，但我希望这有助于某人： - ）
