php - How to pass parameters in index function in codeigniter

Question

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

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.

this is currently what it looks like:

class Search extends CI_Controller{

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

}

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

Answer 1

• 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

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.").
