【中文标题】带有 CodeIgniter 的 PayPal IPN【英文标题】:PayPal IPN with CodeIgniter 【发布时间】:2011-04-28 01:18:59 【问题描述】:我正在尝试在 CodeIgniter 中构建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)并提交表单
用户被发送到 PayPal 支付
付款成功后,用户返回网站,个人详细信息存储在创建用户帐户(会员资格)的数据库中。
还有表单验证的添加,我在 CodeIgniter 中使用了 form_validation 助手,但是这需要在 PayPal 支付之前完成。
我曾尝试实施 Ran Aroussi 的 PayPal_Lib,但我觉得它没有足够清晰的文档或指导。任何已实施的示例或建议将不胜感激。

【问题讨论】:
Paypal 是一个相对难以使用的 API。我个人会使用像 DPS 这样的服务。 paymentexpress.com 如果您将“if ($this->CI->input->post())”更改为“if (isset($_POST))”,该库可以正常工作。你遇到了什么错误? 【参考方案1】:这是 Jamie Rumbelow 提供的一个贝宝库,我一直在使用它并进行了一些细微的调整:

【参考方案2】:以下是我在 Ran 的库中使用的未修改代码。 希望对您有所帮助。

【参考方案3】:我发现 Ran 的库也有点难以使用,所以我写了一个替代品 - 它还具有对交易执行更多检查的好处,并将 IPN 调用和订单详细信息记录在您的数据库中。这是 GitHub 上的库,希望对您有用:

这个 Alex 做得很好。但是,您有不需要教义的版本吗? 嗨 BrynJ,是的 - 现在有一个不需要 Doctrine 的版本以上是关于带有 CodeIgniter 的 PayPal IPN的主要内容,如果未能解决你的问题,请参考以下文章
