Is there anyone full tutorial about multi languange from database

Well... it's pretty simple actually. You first need to do an admin section where you post your articles in different languages. The link that @ivantcholakov sent you to is the best resource regarding the ways you can organize your tables (also recommend the fourth approach). Now, if you've followed my tutorial, you can simply put the flags inside the pages those links having to send to the same page (for example if you have a page at http://example.com/article/testing-the-language, the french flag would send to http://example.com/fr/article/verifier-la-langue, and the romanian flag would have a link to http://example.com/ro/articol/verifica-limba). Now, the controller will receive the language slug and serve the page accordingly. I sure hope I made myself understood. If not, you will unfortunately have to wait for the next episode of my tutorials
