> What would happen is the client (netscape navigator only) would click on the continue shopping AFTER selecting one card to purchase. When
the client when back to the main page the sessionid would be made again. It wasn't recognizing that there was another session already. The
bug
was only happening on Netscape Navigator 4.5 running on Mac OS 6.8 and Win 95. I've never seen anything like this and I have been using
session functions since 4.0 came out. I would have sent this to the php-general list, but it wasn't a programming bug on my part. The sessions
are getting blown away because of an empty form script. I had to change the form link to an <a href> link to make it keep the session data. The
problem would only occur in NN 4.5 on Win95, and MacOS 6.8. If you get time to look at this can you please let me know what happens? The
site it was happening on is http://www.deargreetingcards.com. The form is gone and i'm now using an <a href> tag. Thanks for the help!! And
php
is awesome for web pages...
