Here's a snippet: form = SQLFORM(...blah...) submit = form.element(_type='submit') submit.parent.append(INPUT(_type='submit',_value='Cancel',_name='button')) if request.vars.button == 'Cancel': session.flash = 'profile create was cancelled' session.flash = 'profile update was cancelled' redirect(URL(r=request,f='index')) elif form.accepts(request.vars,session,dbio=False): ...update/insert logic... The cancel works perfectly. A problem that someone mentioned recently (or at least alluded to) is that there's an issue with IE and multiple submit buttons, namely that if the user types a return in a form field, you aren't guaranteed that you'll see the first submit button. So somebody might type a return, and you'll see a cancel. So I ended up with _type='button', and an onclick script to provide the URL.

See this post: https://groups.google.com/group/web2py/browse_frm/thread/f44b6f95b058df5 I'll need to look at that more closely. Thanks. Perhaps I can use button and JavaScript. I think I got it to work. form[0][-1][1].append(INPUT(_type=submit, _name=button, _value=Cancel)) and then after calling accepts: if request.vars.button == Cancel: session.flash = 'edit canceled' else: session.flash = edit accepted redirect(URL(r=request, f='servers')) ...or something similar in the form.error case. (I find that I'm a little fuzzy on the various return cases for accepts, though.) 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. Reset doesn't do it for me; I need an actual cancel function that can do a specified page load. 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'), ) Except it's an SQLFORM, which won't accept INPUT arguments. The big problem with form[0][-1][1].append is that it knows too much about the internal structure of form. I can't expect the guarantee of backward compatibility to include constructs like that. So I'm left with two problems. The IE with multiple submits, and adding a button to the SQLFORM. Both are semi-solved, I think, but not in an ideal way. -- You received this message because you are subscribed to the Google Groups web2py-users group.
