Php Paypal buy now按钮传递一些变量，但不是全部变量

我有一个问题，我正在为客户的网站创建一个贝宝立即购买按钮。虽然名字、姓氏、电子邮件地址和商品名称都在进行中，但账单地址和价格都在进行中。很奇怪，这应该是一个简单的过程。这是我的密码：

$invoicenumber = $row['InvoiceNumber'];
$totalquantity = $row['TotalQuantity'];
$totalprice = $row['TotalPrice'];
$costofshipping = $row['CostOfShipping'];
$firstname = $row['FirstName'];
$lastname = $row['LastName'];
$billingstreetaddress = $row['BillingStreetAddress'];
$billingapartmentnumber = $row['BillingApartmentNumber'];
$billingcity = $row['BillingCity'];
$billingstate = $row['BillingState'];
$billingzipcode = $row['BillingZipCode'];
$emailaddress = $row['EmailAddress'];
echo "<form action='https://www.paypal.com/cgi-bin/webscr' method='post'>

除了确保该按钮是未隐藏的按钮外，如果您在传递地址变量时遇到问题，请确保状态是缩写的，即MA而不是Massachusetts。这就是我的解决方案。

让我猜猜。。。缺少的选项是

paypalsubmitbutton=paypalclientnumber

？尽管如此，我认为这不是解决这个问题的合适论坛。你能给我们展示一下在页面源代码中获得输出的实际代码，而不是PHP生成的代码吗？从您所展示/说的内容来看，我假设您的PHP值没有按照您认为的方式填充。看起来地址肯定在那里，那么为什么它没有出现在paypal收银台上呢？然而，价格显示为0，尽管该变量绝对正确。我在paypal按钮上方有一个select sql查询，而且变量肯定会被填充，特别是当一些变量被填充时。已检查以确保变量中的列名正确。我将确保price变量实际设置为正确的值。
