I have a question regarding login through Facebook.
I have a database with a users table and I have a normal registration and login system, but I wanted to implement the login system through Facebook.
How do I let the system know when to register or log in? For example, I enter Facebook the first time and the site has to create a space in the database for me but the second time it should access my data already recorded, how do I do it?
Thanks for the help.
