项目名称和描述的 Paypal payflow 名称值对

Question

这是来自 PayPal 支付页面:

您的订单摘要说明

Current purchase$61.00

Item total $61.00
Tax $5.49

Total $66.49 USD

“描述”字段为空，唯一显示的是货币值(value)，而不是交易描述、用户名或任何其他内容。

我通过名称值对发送交易。

"USER=".$this->user
 . "&VENDOR=".$this->vendor;
 . "&PARTNER=".$this->partner
 . "&PWD=".$this->pwd;
 . "&TRXTYPE=" . $this->trxtype . "&CURRENCY=" . $this->currency
    . "&TENDER=C" //C = Credit Card
    . "&AMT=" . ($data['price'] + $data['shipping'] + $data['tax'])
    . "&ITEMAMT=". $data['price']
    . "&SHIPPINGAMT=". $data['shipping']
    . "&TAXAMT=". $data['tax']
    . "&CUSTOM=". urlencode("RESEARCH POSTER FROM 1: ".$data['desc'])
    . "&DESC=". urlencode("RESEARCH POSTER FROM 2: ".$data['desc'])
    . "&L_DESC0=". urlencode("RESEARCH POSTER FROM 4: ".$data['desc'])
    . "&L_DESC1=". urlencode("RESEARCH POSTER FROM 5: ".$data['desc'])
. "&ITEMNAME=". urlencode("RESEARCH POSTER FROM 6: ".$data['desc'])
. "&NAME=". urlencode("RESEARCH POSTER FROM 7: ".$data['desc'])
. "&L_NAME0=". urlencode("RESEARCH POSTER FROM 3: ".$data['desc'])
. "&LASTNAME=". urlencode($data['lastname'])
. "&FIRSTNAME=". urlencode($data['firstname'])
. "&EMAIL=". $data['email']
. "&VERBOSITY=" . $this->verbosity;

不幸的是，订单摘要页面完全没有详细信息。我无法让它显示任何描述或项目名称。

我应该使用的名称值对变量是什么？

我已经尝试过，DESC、ITEMNAME、L_NAME0、L_NAME1、NAME、L_DESC0 等。但它们都不起作用。

Answer 1

documentation (从第132页开始)显示L_NAMEn、L_DESCn等以0开头。它还有一个注释...

To enable line-item support, send an email from the Primary email address on the account to payflow-support@paypal.com

你做到了吗？
