DB::commit() not saving changes to database

[N00BEST]

I'm making modifications to two tables in a given time and trying to avoid concurrency problems, so I'm using DB::beginTransaction();

Everything executes just fine, but when I do DB::commit() nothing changes in database. If I execute the exact same code without the transaction, everything goes just fine.

This is my code, I need to add the like to the liked_videos table and increase or decrease the likes/dislikes values on the videos table. If I run this exact code without the DB::commit() it works.

Working code:

I also tried to use DB::transaction($callback) to achieve this, but didn't work either. My database is like this:

Initial State:
liked_videos table

videos table

After not working code (with transaction and commit) it remains the same.

If executed without the beginTransaction and commit it updates the tables to this:

After working code State:
liked_videos table

videos table

I've also tried to run the transaction directly on the database to check if the problem was on my MySql server, but it worked just fine.

I need some advice on see what could be wrong with this or which file I should check in order to submit a pull request with a possible solution.

Thanks in advance.
