how can i get url look like that?

I have created a controller to try and imitate your urls.

Here is the controller

Code:

<?php

class Articles extends Controller {

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

    }
    
    function category($cat=NULL,$id=NULL){
        echo 'cat: ',$cat,', id: ',$id;
    }
}

The URLs for this controller are

Code:

http://site.com/articles/category/press/45

The page output for the above URL is

cat: press, id: 45

I applied this route

Code:

$route['service:(:any)/(:any):(:any)/ID:(:num)'] = '$1/$2/$3/$4';

I got the desired output.

Another less specific route that worked is

Code:

$route['service:(:any)/(:any):(:any)/:any:(:num)'] = '$1/$2/$3/$4';

Make sure the first letter capitalization for "service" is correct. Other than that I don't see why the routes aren't working for you. If you can access the controller method using the original URL, a correct route should not take you to a 403 page.
