You can just add it to the data you save in the controller action.
Something like:
function add() {
if (!empty($this->data)) {
$this->data['Model']['amount_plus_fee'] = $this->data['Model']['amount'] +
10;
$this->Model->save($this->data);
}
}
So amount_plus_fee wouldn't be in the form necessarily, but it's a field on
the table that you save here.
