Codeigniter multiple controllers vs many methods?

Question

I have a site that has a lot of pages that lye at the root (ex. /contact, /about, /home, /faq, /privacy, /tos, etc.). My question is should these all be separate controllers or one controller with many methods (ex. contact, about, index within a main.php controller )?

UPDATE: I just realized that methods that are within the default controller don't show in the url without the default controller (ie. main/contact wont automatically route to /contact if main is the default controller ). So you would need to go into routes and override each page.

Answer 1

If all of these are just pages, I would recommend putting them into a single controller. I usually end up putting static pages like this into a 'pages' controller and putting in routes for each static page to bypass the '/pages' in my URLs.

Answer 2

If they are share the same functionality, so they should be in the same controller.
for example, if all of them are using the same model to take content from, so, one controller can easily handle it.
Why in one controller? because you always want to reuse your code.

   class someController{
    function cotact(){
        print $this->getContentFromModel(1);

    }

    function about(){
        print $this->getContentFromModel(2);
    }

    function home(){
        print $this->getContentFromModel(3);
    }

    private function getContentFromModel($id){
        return $this->someContentModel->getContentById($id);
    } 
}

(instead of print, you should use load a view)

See in my example how all of the function are using the same getContentFromModel function to share the same functionality.

but this is one case only, there could be ther cases that my example can be bad for...
