Configuring Multi-Language Support

Using dropdown inputbox in every pages. On change it will refresh & change page Lang. All code I put in MY_controller where I process to store and retrieve Lang from cookie.

It is ok but how will you switch to current language _lang file with code?

I'm a person from Turkiye. I don't know English very well and i can't write what i want to say sometimes (as now happenes   ).

If i write something by mistake; please don't distress it and try to understand what i want to write.
