Answer 1

试试http://ellislab.com/codeigniter/user-guide/libraries/form_validation.html#rulereference中的 is_natural规则

$this->form_validation->set_rules('calls_abandoned', 'Calls abandoned', 'required|integer|is_natural|less_than[101]|decimal');

You can try custom validation like this :

function maximCheck($num)
{
    if ($num > 0 && $num < 100)
    {
         return TRUE;

    }
    else
    {
        $this->form_validation->set_message(
                        'your_field',
                        'The %s field must be in 1 to 100'
                    );
        return FALSE;
    }
}


$this->form_validation->set_rules(
        'your_field', 'Your Number', 'callback_maximCheck'
    );
