I find the best way is to do dtml-if itemdtml-var itemdtml-else*
needed/dtml-if on the fields of the form and have dtml-try trying to do
something with all the values (email, write, update database). If they are
not all there it brings you back the the form (I always build it in one
method which makes it easier).
Examples:
http://market.gotschool.com/register.html?type=school - in production so
leave out your email
http://fundraising.gotschool.com/tell_a_friend.html

Subject: [Zope] Validating page entry help
I was wondering what the best way to validate a users input on a page.
Currently I submit a page to an interim page that checks for certain values
using dtml-if's and dtml-unless'.
If everything is fine I go on to the next page. If something is missing I
need to go back, I haven't figured out how to do this part.
If I use META HTTP-EQUIV="refresh" content=5;URL=dtml-var
"REQUEST['HTTP_REFERER']" all the input is lost from the form.
So my questions are:
1. What is the best way to do page validation before it is submited.
2. If the way I am doing it seems to be an ok way, how do I go BACK with out
losing everything (equivalent of pressing the back button)
