如何在 CodeIgniter 中使用 GET 表单? [英] How can I use GET forms with CodeIgniter?

问题描述

我知道 CI 主要基于 URL 段，但我想要一个查询字符串:blahblah.com/search.html?q=keyword

I understand that CI is mostly URL segment based, but I want to have a query string: blahblah.com/search.html?q=keyword

当我尝试 $this->input->get( "q" ) 时，它返回空.是否有路线或我需要配置的东西?

When I try $this->input->get( "q" ), it returns empty. Is there a route or something I need to configure?

推荐答案

在 CodeIgniter 中获取查询字符串的最佳方法是使用 Google.每天至少 10 次在论坛、此处和 Twitter 上提出(并回答)这个问题.

我更喜欢这个而不是其他方法，因为它不会像其他一些方法那样对应用程序产生影响，并且不需要任何疯狂的黑客攻击来让它工作.

I prefer this over others as it will have no application-wide effects like some other approaches and it won't require any crazy hacking to get it working.

如果您希望在整个应用程序中都支持 $_GET，只需将 parse_str 放入 MY_Controller 或 pre_controller 钩子中.

If you want this $_GET support throughout the entire app, just put the parse_str into MY_Controller or a pre_controller hook.
