Redirect users to their main language first visit. I needed it only on the front page, but you can simply remove the if statement if you need the functionality on every page. The language detection is done by Smart IP. Which is a separate module.
I made a separate module for this. The code uses smart_ip module so i made it a requirement.

  1. name = Smart IP redirect
  2. description = "Redirect users to right language on first visit, using Smart IP for country detection."
  3. core = 7.x

  5. dependencies[] = smart_ip
Programming Language: YAML
The code with comments. Everything should be self explanatory.
