I have been having some trouble understanding "empty()" -- it doesn't
seem to want to work for me in any situation
Anyway, I seem to have it all working, pretty much. Still testing...
I think the problem had to do with either sessions, or setting the right
parameters for the submit option or using action="<?
$_SERVER['PHP_SELF'] ?>" -- the latter seems to work ok. Although, it is
interesting that it is possible to use another file for the action - but
that seems a bit redundant as you have to populate that file with almost
the same stuff that is in the original form file...
I'm making progress, but I don't think I'm learning a lot other than to
contain my frustration. ;-)
