I'm wondering about further usage of "a*dding extra form elements to
SQLFORM", as written in the manual (link and code at the bottom). I have a
table that works fine to insert records into, fully automated with SQLFORM.
When I added an agree field to the SQLFORM, the form is still accepted upon
posting, but the form data is no longer saved like it was before. Does it
mean I now have to manage all data saving manually, when adding an extra
form element? If so, what is the best practice to save this form data?**I'm
just using a simple table, something like a table with the name "person",
and columns "name", "age", "profession". The table will upscale, and since
there are so many ways to do things in web2py I don't know where to start!*

Adding extra form elements to SQLFORM
Sometimes you may wish to add an extra element to your form after it has
been created. For example, you may wish to add a checkbox which confirms
the user agrees with the terms and conditions of your website:
form = SQLFORM(db.yourtable)
my_extra_element = TR(LABEL('I agree to the terms and conditions'),
INPUT(_name='agree',value=True,_type='checkbox'))
form[0].insert(-1,my_extra_element)
The variable my_extra_element should be adapted to the formstyle. In this
example, the default formstyle='table3cols' has been assumed.
After submission, form.vars.agree will contain the status of the checkbox,
which could then be used in an onvalidation function, for instance.
