If someone leaves my website... do this...

Is there a function, or a way I can know if someone leaves my page so I can run an sql command and delete their username from my database ?

this is a bit tricky, I've messed with it some time ago, but never found
THE solution

maybe u could use Javascript's onUnload="" which must be written
in the body-tag, you could call a form in the called function, which
performs the required actions
only it would be called each time, the user hits a link, even on your site

probably better is some kind of timeout, for example a function
is called every time a user enters the site.
it deletes all sessions which are older than ~5 minutes, else renew
its timestamp (with touch())

Ok I put a javascript on my page, so if they exit it opens a new window of my logout.php which takes their $nick and deletes it from the database. Problem now is though, when they leave my page, $nick is reset to nothing, so it tries to delete nothing from my database.

Look here : http://www.swgfreak.com/k/chat.html

When you exit my sql query will be outputted.

hmm, you open a new window? maybe you could pass $nick in the
url

like
window.open("logout.php?nick=$nick");

no idea if this works

Ya that was a good idea but didn't work 🙁 It's still not finding the users name when they leave my site.
