Can a hook load a controller?

Without thinking too much about it I would say no.

The controller that will be loaded is defined by the url/the routing defined in config/routes.php

The "pre_system" or the "pre_controller" controllers could be used to redirect to another url I guess...maybe even hack the routing? Don't know...just a wild guess here.

Why would you need that anyway?

I need to make a dynamic multilanguage website, take a look at the urls:

en/gallery/
pt/galeria/
it/galeria/

both should trigger the gallery controller.
1) the params are stored,
2) then converted in the main language (gallery to gallery, and galeria to gallery)
3) load the controller named gallery

Let us know exactly what you are trying to achieve and we might be able to offer a good solution that fits with CI's philosophy and conventions.

Sorry about that. I posted mine before seeing your response.

You could achieve 2 and 3 with simple routing rules:

Code:
$route['([a-z]{2})/gal([^\/]*)'] = "gallery/$1";

Then take care of #1 in the gallery controller constructor, where $this->uri->segment(1) is the language code.

No problem. I know but I don't want to work with routers because I can add new categories and then I should make them available in different languages, and i have to mod always the route file.

Look at the code I have to use to get the controller name, then this should dispatch the action to that controller, but how?-I really don't know. Here I share my code:

Advanced routing usually involves overloading the core Router class (creating a MY_Router library). If you take a look at the Router class, it should be pretty clear where you'll want to make your modifications.
