MYSQL - Save and display user info. Base pages off user info

Hello, for this project, i am wanting to be able to let users register for my site. (register.php.) I need for user info/data from fields to store as sessions. And for sessions to resume with updated database (if admin updates user points, rank, ect..) after session ends and user logs back in. After [login to view URL] they will be directed to a page where they validate their gaming information. ([login to view URL]) I need for whenever user selects which console they use (xbox or playstation) this will store in session, and later when user selects which event, ([login to view URL]) code will display the next page based off of console. If xbox then page = [login to view URL], if playstation then = [login to view URL]
