Hello, all -
I had some questions regarding the creation of "intelligent" forms -
forms that take data, and then parse it for errors, "real" data, etc etc.
The first idea I had was to make a function to display the form. When
the form is submitted, the page would be called again (i.e. the form's
ACTION=itself), and then the POST or GET or SESSION variables will be
the arguments to the form. The idea is, when this happens, the form
will be able to check the data that was sent, verify it, etc etc. If
there are no problems with the data, then the user is directed to step 2
of the form, or the second page, to enter in additional data. But how
should the redirection happen?
At that point, am I able to manipulate the headers for a different
Location:, that location being the second form to be filled out? Since
this would be the first data sent to the BROWSER, I thought that this
might work.
I've been toying with both of these ideas with varying success, but
haven't quite gotten it figured out. I'm sure that, with due time, I'll
be able to figure it out. However, I just want to make sure that this
is a "correct" way of writing forms, and if it's normally accepted as a
common practice, so I don't waste my time doing something that might not
actually work.
Thanks!
