Yes. You can also do
def index():
form=FORM(INPUT(_name='test', requires=IS_NOT_EMPTY()))
if form.accepts(request.vars,session=None,formname='test'):
response.flash='form accepted'
elif form.errors:
response.flash='form has errors'
else:
response.flash='please fill the form'
return dict()
<form>
{{=INPUT(_name='test',_class='...')}}
<input type='submit' />
<input type='hidden' name='_formname' value='test' />
</form>
or (latest trunk)
{{=form.custom.begin}}
{{=form.custom.widget.test}}
{{=form.custom.submit}}
{{=form.custom.end}}
