when browser is closed
|

| Hi,
I have a site accessible via a login system. I would like to track login and
logout time for every user. I can get the login time no problem - as every
time someone logs in, a row is added to a mysql table. The problem happens
with logout as almost no one uses the logout button; rather they just close
the browser window.
My question is therefore - am i able to capture the time the browser is
closed? all login data is stored in a session; so is there a way to find out
the time the session got deleted which would mean user has left ?
Kind regards
T

No.

The session being deleted does NOT mean the user has left. And the
user may leave WITHOUT closing the browser window (he may type in
a URL, click on a bookmark, etc.) Unless the user is highly motivated
to explicitly log out (like the site contains private info or can
be used to spend real money), the vast majority of logouts are going
to be by timeout.
You also don't get to run code when the session data is about to
be deleted.

I'd suggest saving the last page call in your table. Each time a page is
called during one session, update the last page call column to the
current time.

Not strictly true. The onunload event can be captured within a page and
by use of a HTTP redirect used to call appropriate code to clean up
session data etc ... Be warned though as always various browsers don't
support onunload, but my experience with IE has so far been OK since
version 4.

The onunload also triggers when a user moves off of your page by typing
a different URL.
