Hi there everyone, I have a login system which uses sessions, and when people login it puts the date they logged in in their profile and moves their last login date over to another field, that works fine, but how can I check if someone has logged out via code? In other words, if someone does what they want and then just closes the browser without logging out no record is saved, how can I tell whether they have logged out / gone from the website ? I need to know this for security. Which brings me to my next question :-) How would I make it so only 1 person can login at any time with any given username/password combo? I know I have to track the sessions, but not sure how :-( Any help would really be appreciated.
