PayPal IPN与CodeIgniter

phpcodeigniterpaypalpaypal-ipn
7
我正在尝试在CodeIgniter构建的网站上实现会员订阅服务。我希望使用PayPal管理付款，但是在实现过程中遇到了很大的困难。
我的目标是：
1. 用户填写包含个人详细信息的会员表单。 2. 用户选择订阅选项（8种不同价格之一），并提交表单。 3. 用户被发送到PayPal进行付款。 4. 付款成功后，用户返回网站，并将个人详细信息存储在数据库中以创建用户账户（会员）。
还需要进行表单验证。我在CodeIgniter中使用form_validation助手，但必须在PayPal支付开始之前完成验证。
我已尝试实现Ran Aroussi的PayPal_Lib，但感觉文档或指南不够清晰。非常感谢任何已实施的示例或建议。

Paypal是一个相对较难使用的API。我个人会使用像DPS这样的服务。http://www.paymentexpress.com/ - Petah
那个库运行良好，如果你将 "if ($this->CI->input->post())" 改为 "if (isset($_POST))"。你遇到了什么错误？ - stef

以下是我使用Ran的库时未经修改的代码。 希望能对你有所帮助。

我发现Ran的库有些难以使用，所以我写了一个替代品 - 它还可以对交易进行更多的检查，并在您的数据库中记录IPN调用和订单详细信息。这是GitHub上的库，希望你会觉得它有用：

Alex，你做得很好。但是，你有没有一个不需要doctrine的版本？ - BrynJ
