[Flask] Access form data in view function

[Alex Hall]

One more update: my form seems to only pass one field, no matter what. I
made a little loop in the function that processes the form:

 for i, j in request.form.iteritems():
  print "form[{i}]={j}".format(i=i, j=j)

This only ever prints my "orderNumber" text field, whether that field has a
value or not. It never prints the other text field in the form, the
checkbox, or either of the multiple select fields. I've been over the form
template, html, and class again and again, trying to spot what I did
differently for the orderNumber field that makes it stick when nothing else
does. I've even reversed the order of fields in the form, to see if it's
just the first field in the form that gets saved, but that didn't change
anything. I'm really at a loss, and I've spent hours googling this to no
avail. It makes no sense that the form would grab one field, but no others.
I can't figure out what I could possibly be doing, and no one I could find
has this problem. What code would it help to send to the list for you all
to look at? Thanks.
