SagePay 协议 3.00 PHP 服务器集成查询字符串 POST

Question

我是一名初级 PHP 开发人员，正在尝试将 sagepay 与我的网站集成，这样客户就可以访问我的网站“www.example.com/payment”上的链接，并填写一份表格，其中包含他们欠我的金额和我分配给他们的相应发票号码及其帐号、账单明细、地址、全名、邮政编码和送货地址，然后应该创建一个发送到 SagePay 服务器的查询字符串。

下面，我有一个我将在网站中放入的表格示例：

<form action="https://test.sagepay.com/gateway/service/vspform-register.vsp" method="post" id="SagePayForm" name="SagePayForm">
<input type="hidden" name="Vendor" value="Vendorname" />
<input type="hidden" name="VPSProtocol" value="3.00" />
<input type="hidden" name="TxType" value="PAYMENT" />
<input type="hidden" name="Currency" value="GBP"><br />
<input type="hidden" name="NotificationURL" value="http://example.com/payment/"
<input type="number" name="VendorTxCode" placeholder="Invoice Number" value="123456"><br />
<input type="number" name="Amount" placeholder="Amount" value="250"><br />
<input type="text" name="Description" placeholder="Description of Invoice" value="Payment for your services"><br />
<input type="text" name="BillingFirstnames" placeholder="Firstname(s)" value="Fname Mname"><br />
<input type="text" name="BillingSurname" placeholder="Surname" value="Surname"><br />
<input type="text" name="BillingAddress1" placeholder="Address Line 1" value="BillAddress Line 1"><br />
<input type="text" name="BillingAddress2" placeholder="Surname" value="BillAddress Line 2"><br />
<input type="text" name="BillingCity" placeholder="City" value="BillCity"><br />
<input type="text" name="BillingPostCode" placeholder="Post/Zip Code" value="W1A 1BL"><br />
<input type="text" name="BillingCountry" placeholder="Country" value="United Kingdom"><br /><br />

<input type="text" name="DeliveryFirstnames" placeholder="Firstname(s)" value="Fname Mname"><br />
<input type="text" name="DeliverySurname" placeholder="Surname" value="Surname"><br />
<input type="text" name="DeliveryAddress1" placeholder="Address Line 1" value="BillAddress Line 1"><br />
<input type="text" name="DeliveryAddress2" placeholder="Surname" value="BillAddress Line 2"><br />
<input type="text" name="DeliveryCity" placeholder="City" value="BillCity"><br />
<input type="text" name="DeliveryPostCode" placeholder="Post/Zip Code" value="W1A 1BL"><br />
<input type="text" name="DeliveryCountry" placeholder="Country" value="United Kingdom"><br />

<input type="submit" name="submit" value="Submit">
</form>
