The most user friendly option would be that the cause select/radio button checks if the user still can donate or not. So in an ajax controller you can put this code

Code:

echo ($this->db->query('select count(*) as rows from table where donation = ?',array($input))->row()->rows < 5)?'they have enough money already':'You can give a little more';
