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';

```
Always maintain your routing rules

like

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

```

always follow this pattern for routing 

if you add like this

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

```

then always first condition will be true every time.
