使用 CodeIgniter 的 PayPal IPN [英] PayPal IPN with CodeIgniter
本文介绍了使用 CodeIgniter 的 PayPal IPN的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试在一个内置于 CodeIgniter 的网站上实现会员订阅服务.我希望使用 PayPal 来管理付款，但实施起来非常困难.
我想要实现的是:
- 用户填写会员表格个人资料
- 用户选择一个订阅选项(8 个选项中的 1 个 - 每个不同的价格)并提交表格
- 用户被发送到 PayPal 进行支付
- 成功付款后用户将返回网站，个人详细信息存储在创建用户帐户(会员资格)的数据库中.
还添加了表单验证，我在 CodeIgniter 中使用了 form_validation 助手，但这需要在 PayPal 付款开始之前完成.
我曾尝试实现 Ran Aroussi 的 PayPal_Lib，但我觉得它没有足够明确的文档或指南.任何实施的示例或建议将不胜感激.

以下是我在 Ran 的库中使用的未修改代码.希望有帮助.

I am trying to implement a membership subscription service on a website built in CodeIgniter. I wish to use PayPal to manage payments, and am having a very hard time implementing this.
What I am trying to achieve is:
- User fills in a membership form with personal details
- User selects a subscription option (1 of 8 choices - each different price) and submits form
- User is sent to PayPal to pay
- User is returned to site upon successful payment and personal details are stored in database which creates user account (membership).
There is also the addition of form validation, I use the form_validation helper in CodeIgniter, but this needs to be done before PayPal payment can commence.
I have attempted to implement the PayPal_Lib from Ran Aroussi, but I feel it has not enough clear documentation or guidance on it. Any implemented examples or advice would be much appreciated.

Below is the unmodified code that i used with Ran's library. Hope it helps.
