Question

I have a Controller named Categories and one function in it called index with 1 parameter $cat_id

so it looks like this:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class categories extends CI_Controller {

    function __construct(){
        parent::__construct();
    }

    public function index($cat_id = null){

    }
}

the problem comes when i call it from the browser… i use this:

http://www.mysite.dev/categories/12311323

but returns 404 error page

instead if i use

http://www.mysite.dev/categories/index/12313131

will work fine…

how can i make sure it wont need index in the URL for the index function?

Answer 1

The default CodeIgniter routing is /controller/function/argument. In order to specify an argument, you need to first specify the function. If you want to specify an argument without the function, you need to define a custom route. Adding this line to your route configuration file should do what you want.

$route['categories/(:num)'] = "categories/index/$1";
