Friendly URL Rewriting

Hi,
For the moment my url's are :

Code:

http://website.fr/game/ID/name-of-my-game

I would like to have this kind of URL :

Code:

http://website.fr/game/name-of-my-game

How can i do that ?
My links are create like that :

Code:

<?=base_url().'game/'.$game->id.'/'.url_title($game->titlePost)?>

Is it possible to redirect on 404 error when someone change the url  

Code:

http://website.fr/game/name-of-my-game

by  

Code:

http://website.fr/game/name-of-m

I wonder what your controller Game looks like.
Does it have a function (method) called ID?
Or is ID a parameter, just like the name of the game?

In the controller's method where you are passing the name of the game, you'd just check the db to see if "name-of-my-game" existed, and if not do a show_404(). So it will only display something if it exists, so if someone entered "name-of-m" it would 404 since it doesn't exist.

It's an ID parameter  public function game($id = "")

Oh can i do that for changing url and how can i link the name of the game and the id ?
name-of-game2 = id2

You can get the ID by the name.

In your database the table game should looks like :
id | system_name | human_name

The record :
2 | name-of-game | Name of game

In your controller add a method that will search after the uri segment in your database, if the uri match the system_name you can return all data, if not you can display a 404 error page.
