best practices on Form Reuse - keeping all forms in a central location with validation

@chuckleberry:
A bit late, but no, in my example you don't have to alter the code in the library at all. The only thing you alter for every form is
-set up an an array in the controller
-initiate a new form object in the controller
-process the form, like below

Code:

if ($form->metadata['validated'] == true) {
    // process from using the values in associative array $form->form_results, e.g.
    // $this->db->set($form->form_results);
    // etc.
}
else {
    // Load view and pass $form->form_elements
}

In the view you will have an array of form inputs ($form->form_elements) that you can loop through for display. You can write a generic function for this display as well.

Works like a charm. And because the $form object has an ID you can use multiple forms in a single page, also widgets. All that you alter is an array in the controller and the code that you need to process the form.
