Thank you
Mengu's initial post uses a model and I believe I offered sample code to validate a form in his example. The form can be built any way you want, it does not matter. Now if you narrow down the question don't expect the answer to still apply. Besides web2py is after all a database driven framework. And if you say you don't like using any of the included tools to work with forms then I don't know what you are really after. > carlo > > On 15 Mar, 21:09, DenesL <denes1...@yahoo.ca> wrote: > > > On Mar 15, 6:28 am, Mengu <whalb...@gmail.com> wrote: > > > > > First of all, I am not sure what is the problem you are trying to > > > > solve.
