Submitting an Unknown Number of Field Elements

Ha ha. Fine, I deserved the lmgtfy.

The application stores each email address on a new row. At this point it's not necessary for these email addresses to be related.

Tried to cycle through the items with something like this -

Code:

foreach($_POST['email'] as $item) {
                $this->input->xss_clean($item);
                $this->form_validation->set_rules($item, 'Email', 'required|valid_email');
            }

but no dice. I'm really new to php too.

Thanks,

Joe
