ross, i have the logic and error checking (for both
form entry and db process) down. i'm just wondering
if it is worth displaying the entry for a quick user
visual check - not in the form, but above the form.
for large forms, though, this takes a lot of overhead,
although, my sessions approach could be eliminated to
reduce lots of coding.
you struck on something that may be even more
important to me. you seem to have a function that
iterates through the form elements.
this method seems to work nicely, although i don't
know enough to decide if it will work for me. i'm
using manuel lemos' forms class from phpclasses.org.
http://www.phpclasses.org/browse/package/1.html
do you have a link to a tutorial that explains this
approach in more depth? i'll do some web searches now
to see what i can come up with and i'll report back.
