You shouldn't register before the form is complete right and not after every 
submit. 
something
like:
'}

?>


etc

[PHP] Asking for help...

[Ashley M. Kirchner]

 Okay, I give up.  I can't figure this out.  So, instead of spamming
the list with my code, I'll ask for help and those who reply I'll send
the code to.  The problem is as follows:

 I'm building a multi page form (called form.php) which 'include's
each $step one by one (step1.inc, step2.inc, etc., etc.).

 That page (form.php) submits to a process script (process.php) which
does several things:

- checks for each form field to be filled.
  if a required field is empty, flag $error
- if the field is filled, session_register() it.
- if there is an $error, resubmit the $step back to form.php
- if there is no $error, submit $step+1 to form.php

 And the whole process gets repeated every time form.php is
resubmitted.  So, in theory, at the end of the 3 pages that I have, the
last submit will cause process.php to grab all the variable/value
combinations and (for now) sends me an email.

 Problems I'm facing:
 1) Let's say a user leaves out a field (or more) and submits the page.
process.php diligently causes an $error which sends the same $step
back to form.php.  Now the user fills in what was missing, but
DELETES another field and resubmits.  At this point, that variable
was already registered, and deleting the value from the form has no
effect.  The old value is still there and gets submitted.  I need
to check for this somehow.

 2) There are also optional fields on the form (thinks like a second
field for Address, Telephone#, etc.)  These will also need to be
registered if they have been filled.  And they are.  Problem is,
sometimes they're not (I can't seem to be able to pin down WHY).

 3) If a required field hasn't been filled in the first go around, the
whole process gets stuck.  In other words, when the same form gets
displayed again, and the user DOES fill in that field and resubmits
it, it just comes back and says that field is still missing.
Even though when I echo that variable prior to the process reaching
the point where it checks if there is anything missing, I get a
value returned - so the field IS filled.  Still, it fails when it
reaches the checks.



 I'm sure there are more, but right now that's what I'm faced with and
it's driving me insane.  So, if some brave soul out there wishes to
read my (no doubt) crappy code and tell me what I did wrong, I'll
appreciate it.  Please reply to me off-list and I'll give you the
current code.
