Language related question

[eluser]Tsu88[/eluser]
Hello!

I am new to codeigniter (using it for less than a month and already have two project to make) and new to using framework for doing job done. I learned about MVC quite quickly and I like CI a lot.

So here is my situation:

I am making a school project - renewal of laboratory site - and it has to be in our native language (slovenian) and in english. I read about language classes and all but I don't get one thing.

Let's say I have a table called News and there are usual fields, where I have two fields for content: content_sl and content_en. In my view file I would like to display content of content_sl if user defines his language as Slovenian and vice versa.

So I would create set of controllers for english and another one for slovenian interface? I don't know the right approach, because I never worked on multilanguage page before.

Could I just create unique controller that would have a variable that defines language? Therfore when visitor selects english, query would be sent to controller saying I want english and controller would look in a database and get values for english ... ?

I am sorry if all together sounds a little bit confusing, but take in consideration that I am new with all this framework work.

I would be really happy if one could direct me in right direction, I will do my work (teaching and reading) I just need a hint

ADDED:
I forgot to add that i would like my URL to look like
www.example.com/en/something
and
www.example.com/sl/something ...

So when user selects his language that en or sl would always be before all other functions.

Thanks in advance,
Matic
