CI input - excluding submit value in array

[eluser]johnpeace[/eluser]
Set the rules in a loop through the $_POST array?

Code:

foreach($_POST as $p) {
    $this->form_validation->set_rules($p, ucfirst($p), 'required|trim');
}

You won't have a 'human readable' field in the $_POST array...just the name and value of each field.
