Start with the overview chapter. You are trying to submit data with a form.
web2py handles this very easily, and it is all documented well in the book.
The book will take you through several ways of doing this in web2py.
You should immediately follow the lead of the book (overview chapter under
the heading "Say my name") which will show you how to get it working.
