Yes, but be careful of multiple submit buttons.

That is inevitable since you need to handle two different situations in one action. So I would suggest just use a normal html reset button at most. > > Question: what exactly is form[0][-1][1].append appending to? Can I append > more than once to that same object? Yes. FORM is a container for many components. You can change it if you want to. But a more readable style should be: form = FORM( ... # all the normal stuff INPUT(_type='submit'), INPUT(_type='reset'), ) -- You received this message because you are subscribed to the Google Groups "web2py-users" group.
