【问题描述】：

我正在执行以下操作以将多个项目添加到 Paypal，但它不起作用。没有任何项目被添加。但是，如果我只添加一个项目而不添加附加“_1”、“_2”到 item_name 等，那么一切都会完美运行。在这种情况下我做错了什么？

表格

<form name="paypal_auto_form" action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post">

<input type="hidden" value="2" name="rm">
<input type="hidden" value="_xclick" name="cmd">
<input type="hidden" value="USD" name="currency_code">
<input type="hidden" value="[e-mail]" name="business">
<input type="hidden" value="http://[::1]/d/paypal/success" name="return">
<input type="hidden" value="http://[::1]/d/paypal/cancel" name="cancel_return">
<input type="hidden" value="http://[::1]/d/paypal/ipn" name="notify_url">

<input type="hidden" value="Laptop" name="item_name_1">  
<input type="hidden" value="1" name="custom_1">
<input type="hidden" value="1" name="item_number_1">
<input type="hidden" value="500.00" name="amount_1">
<input type="hidden" value="1" name="quantity_1">

<input type="hidden" value="Laptop" name="item_name_2">
<input type="hidden" value="1" name="custom_2">
<input type="hidden" value="1" name="item_number_2">
<input type="hidden" value="500.00" name="amount_2">
<input type="hidden" value="1" name="quantity_2">

<p><input type="submit" value="Click here" name="pp_submit"></p></form>

结果

【问题讨论】：

我不完全确定我看到了任何 php 代码，而且 html 表单也没有竞争......

我刚刚在问题中添加了相关代码。表格实际上是完整的，它是PHP代码。编辑：现在我也添加了表单代码。

<input type="hidden" value="1" name="upload"> 加这个，看看能不能用

它的 HTML 不是 PHP，是一个错字。

嘿，Farkie，我添加了，但结果是一样的。

【参考方案1】：

请检查 Paypal Api 文档中的所有必填字段。可能缺少某些东西。您的数据中应该有 items 数组。项目（名称、货币、价格、数量）。您还应该有一个对象 Payer（它是付款方式）、redirect Url、details 对象（税金、运费、小计）、金额对象（货币、总额）、交易对象（描述、发票编号、金额、项目）。我做到了，但在 C# 中。您可以使用可用的库。

在 C# 中PayPal-NET-SDK 在 PHP 中 PayPal-PHP-SDK 其他检查文档Payments API

选择最适合您的项目的内容。它认为其中之一应该可以帮助您。

这是一个 C# 示例

using PayPal.Api;
using System.Collections.Generic;

namespace PayPal.Sample

public partial class PaymentWithCreditCard : BaseSamplePage

    protected override void RunSample()
    
        // ### Api Context
        // Pass in a `APIContext` object to authenticate 
        // the call and to send a unique request id 
        // (that ensures idempotency). The SDK generates
        // a request id if you do not pass one explicitly. 
        // See [Configuration.cs](/Source/Configuration.html) to know more about APIContext.
        var apiContext = Configuration.GetAPIContext();
