Hi,
I want to make a page where users can enter e-mails to send an invite.
There will be an array of input boxes (1 e-mail each box) and a send
button.
I was wondering what the best way to generate the form dynamically
was... in case the user wanted to add more e-mails.
Also, is there a way to iterate through the form elements so I don't
have to worry about number/name of input fields?
Thanks,

I forgot to mention, the form loads fine... I get the error on submit.

It works fine if I name them email1, email2, etc. This is the error:

You will need to use jQuery to dynamically add more fields.
Also, you could use a textarea instead and have them press enter, and
then split the string on '\n'
So considering the following html
input type=text name=hi id=hi1 value=hello /
input type=text name=hi id=hi2 value=world /
This will be serialized into
www.example.com?hi=hellohi=world
Which will be parsed by web2py into request.vars like so.
request.vars.hi = ['hello', 'world']

Re: [web2py] Re: Iterate through form input
Unfortunately you will not be able to add fields when using FORM.
You will have to iterate over the request.vars manually.
