Problem with updating session data

Thanks for the response.

I'm expecting that when user which had checked "remember me" come back to me, the session will be generated and user_id column will be updated. This works good when user send a form with correct login and password.

Why are you storing the user ID in the session as well as in a separate column in the session table? What is the purpose of modifying the session table in the first place?

Maybe it's wrong but I don't know how to do it in other way. I've added a new column cause in some cases I need to delete specific user's session (for example this user has been banned and I want to log out him immediately) and it's quite simple to do it with new column (user_id). I would appreciate any tip if there's another way to do it better.

Cheers
