Some of the fields in a form are desired but not required. As a result of these fields being left alone, PHP will return errors similar to:
"Notice: Undefined index: manager in C:\wamp\www\form.php on line 12".
My current question is how do you tell PHP to disregard a field if it's empty? I don't know if this makes a difference but the form has text fields, checkboxes & radio buttons.
