Using HTTP_REFERER may not be exactly what you want. The referring ad
might have appeared on http://www.yahoo.com, but what you really want to
know is that the user clicked on ad number 12345, which features your
SuperWidget 5000. My experience is that you can set the exact URL where
ads take the user. In this case, send the user to a special screen, or
maybe
just include a GET variable, like:
http://www.mystore.com/index.php?ad=12345.
Then always look for that variable in page requests.
If you want to save this info forever, the least invasive thing would be to
create
a new table, keyed by the invoice table.
