如何在Codeigniter的索引函数中传递参数 [英] How to pass parameters in index function in codeigniter

问题描述

这是url的示例: http://www.example.com/search/search-key

here's an example of url: http://www.example.com/search/search-keyword

我正在尝试使其工作，我使用.htaccess删除了index.php，搜索是控制器，我想在index方法中传递参数.

I am trying to make this work, I removed the index.php using .htaccess, search is the controller and I want to pass a parameter in the index method.

这是当前的样子:

class Search extends CI_Controller{

    function index($param){
        echo $param;
    }

}

有什么建议吗?我似乎无法使其正常工作

any suggestions? I can't seem to make it work

推荐答案

• 您需要index段http://www.example.com/search/index/search-keyword.
• 或者您需要使用路线$route['search/(:any)'] = 'search/index/$1';
• 或者您可以查看重新映射
• You need the index segment http://www.example.com/search/index/search-keyword.
• Or you need to use a route $route['search/(:any)'] = 'search/index/$1';
• Or you can look at remap

请记住不要信任用户输入，尤其是当您将其输入到URL中时. CI的最新版本现在支持$_GET变量，因此您可能要考虑使用它或 flashdata .像O' Brien这样简单的searh术语将给您带来致命错误(您提交的URI不允许使用字符.").

Remember not to trust user input, especially when you are throwing it into your url. The latest version of CI supports $_GET variables now, so you may want to look into using that or flashdata. A searh term as simple as O' Brien will give you a fatal error ("The URI you submitted has disallowed characters.").
