Question: This seems really basic but i can't get the hang of it.

I'm trying to send more then one parameter to a method in the controller, like this :

```
http://localhost/ci/index.php/subjects/3/state

```

This is the routings i've tried :

```
$route['subjects/(:num)'] = 'subjects/view/$1';
$route['subjects/(:num)/{:any}'] = 'subjects/view/$1/$2';

```

the method accepted 2 paremeters :

```
public function view($slug, $id = null){

}

```

but i seem to get a 404. How can i get this to work? i need the view method to always accept 1 parameter and optional other parameters.

**NOTE** : I am including the url helper.

Answer: 
you have problem with your route brackets just change it from {} to () brackets will work 

from

```
$route['subjects/(:num)/{:any}'] = 'subjects/view/$1/$2';

```

to

```
$route['subjects/(:num)/(:any)'] = 'subjects/view/$1/$2';

```
I once tried this URI pattern

```
$route['(:any)'] = 'welcome/list1/$1';
$route['(:any)/(:num)'] = 'welcome/list1/$1/$2';

$route['(:any)/(:any)'] = 'welcome/list2/$1/$2';
$route['(:any)/(:any)/(:num)'] = 'welcome/list2/$1/$2/$3';

$route['(:any)/(:any)/(:any)'] = 'welcome/list3/$1/$2/$3';

```

but it didnt worked ... so I replaced it with regular expression

`([a-z 0-9 -]+)` replaced `(:any)`
and
`([0-9]+)` replaced `(:num)`

so it became

```
$route['([a-z 0-9 -]+)'] = 'welcome/list1/$1';
$route['([a-z 0-9 -]+)/([0-9]+)'] = 'welcome/list1/$1/$2';

$route['([a-z 0-9 -]+)/([a-z 0-9 -]+)'] = 'welcome/list2/$1/$2';
$route['([a-z 0-9 -]+)/([a-z 0-9 -]+)/([0-9]+)'] = 'welcome/list2/$1/$2/$3';

$route['([a-z 0-9 -]+)/([a-z 0-9 -]+)/([a-z 0-9 -]+)'] = 'welcome/list3/$1/$2/$3';

```

And it worked for me :)

In order to access the variables in your controllers, you can assign any parameter in the function.

```
class Welcome extends CI_Controller {

    public function list($first, $second)
    {
        var_dump($first);
        var_dump($second);
    }
}

```
