Multilingual working solution ?

I am in search of a multilingual database solution and need help. I checked the extensions and the solutions proposed are not clear.

Many have lacked of documentation or instruction…

Some are obsoelete…

So, which one is the best extension to use ?

Have a nice day.

this one is a extension module I’ve made a couple weeks ago

Let me know if you have any doubt on how to use it

I think I didn’t explain it right. Here the kind of extension I am talking… But this one lack some information…

But thank you for the answer.
