Greetings.
Some of you are familiar with my latest project, a smaller community. I
have implemented almost everything I need, and I wish to thank those of you
who helped me with "which mail is new" and so forth. However, this problem
is quite worse I suppose, but I hope some of you has done something like
this before:
Sessions.
I wish to keep track of every visitor. Not a counter or anything, but more
of when a person signs in, the users nickname will be bound to this session
ID which will keep track of the person is online or offline. I have solved
it like so:
Whenever a person loggs in, I add it's name to a online.dat file. When
the user signs of, I remove the nickname thus the login time from the file.
PROBLEMS?? First one: User must click on "logout" to remove itself. Second:
It does not always remove itself.
Therefore, I ask: How can I create a new session for every visitor (so I
know how many are online at the time), bind this ID to its nickname (so one
row in a file would be: NICKNAME|SESSION_ID|DATE), and how can I make sure
that whenever the browser is closed or whatever, or after a certain time of
inactivity (3 minutes), the user is removed from the file.
All help is greatly appriciated and your name will be on the credits list
too.
- Richard
