Thanks it will be useful. Can you email me the code?
form.accepts(request.vars, session)
detects submission of some hidden fields in the form (this way works
with both GET and POST).
if returns True ONLY if the form was submitted and no errors, else
otherwise.
if form.accept(...)
# accepted and no error
elif form.errors:
# there are error, cannot happen without validators
else:
# form was not submitted
