Hi there :) One of the most common methods of achieving this is by using
session variables. First the user logins in through a form with a username
and a password, you check these against the database to make sure they are
who they say they are, once that is established you could create a session
variable called "$USERID" (or something a little less intutive:) once
retrieving the $USERID, and do a check within every page to see what $USERID
they are and perform the appropriate actions.
Check out sessions at :
Cheers, Joe :)
