我正在使用带有包装类 (PayPalNVP) 的 Paypal API，并试图在 Paypal 上获取生成的付款页面，以在左侧显示项目描述和最终总额。现在它什么也没显示。
我正在尝试将以下变量传递给 Paypal：
$paypal->setNVP("RETURNURL", "http://www.mysite.ca/confirm.php");
$paypal->setNVP("EMAIL", "$strPaypalEmail");
$paypal->setNVP("CURRENCYCODE", "CAD");
$paypal->setNVP("AMT", number_format($fltGrandTotal, 2));
$paypal->setNVP("L_PAYMENTREQUEST_0_NAME0", "2013 Golf Registration");
$paypal->setNVP("L_DESC0", "2013 Golf Registration");
$paypal->setNVP("L_PAYMENTREQUEST_0_AMT0", number_format($fltGrandTotal, 2));
$paypal->setNVP("ITEMAMT", number_format($fltGrandTotal, 2));
$paypal->setNVP("CUSTOM", $amount);
$paypal->setNVP("INVNUM", $orderID);
我认为这会将购买的描述设置为“2013 Golf Registration”并显示最终总数......但事实并非如此。
任何意见，将不胜感激。
