In my application I'd like the user to be able to return to a page that
they have had to leave in order to register or log-in to the
application. (It's a sort of shopping cart)
The URL contains a couple of items of data in the query string.
I figure there are two options (and let me know about others) - 1. pass
the URL back in hidden fields, and 2. every time the user visits a
'product' page, set that page in a session variable - then when they
are done registering I collect the URL and return to that page (so that
they don't have to start their search all over again).
Is there an advantage to either solution. What problems would I have
in resetting the session variable for each page visited?
==
Additional question on the same topic: No single ENV variable that I
can find gives me the full URL. And "REQUEST_URI" gives me too much
for use.
i.e.: Let's say the URL is
http://www.mydomain.com/about/this/thatfile.php?key=42&name=zaphod
It seems that to return to this page I need either the full URL or just
"thatfile.php?key=...etc", but REQUEST_URI gives me
"/about/this/thatfile?key=....etc"
So, I can concatenate HOST and URI variables to get what I want, but am
I missing something here?
I am running sessions in this application.
Thank you for any assistance,
Nelson
