Unable to access an error message corresponding to your field name

I have a callback function that check_captcha which sees if

== 1
(this information is queried from sql).

The problem is that I can not call it from
$self->form_validation->set_rule('captcha', 'call_back_check_captcha')
due to the fact that my function takes in a
var. The way I'm calling it now I get a Unable to access error message. How can I make this work?

function check_captcha( $row)
if($row ==0)//didnt find any
$this->form_validation->set_message('captcha', 'text dont match captcha');
return FALSE;
return TRUE;

function create_member()

$past = time() - 7200;

$this->db->query("DELETE FROM captcha WHERE captcha_time <".$past);
$sql = "SELECT COUNT(*) AS count FROM captcha WHERE word =? AND ip_address =?";
$binds = array($_POST['captcha'], $this->input->ip_address(), $past);
$query= $this->db->query($sql, $binds);

$row = $query->row(); //row query rows : if it found an entry =1


$this->form_validation->set_rules('first_name', 'First Name', 'trim|required');
$this->form_validation->set_rules('last_name', 'Last Name', 'trim|required');
$this->form_validation->set_rules( 'email_address', 'Email Address', 'trim|required|valid_email|unique[user.email_address]');
$this->form_validation->set_rules('username', 'Username', 'trim|required|min_length[4]|unique[user.username]');
$this->form_validation->set_rules('password', 'Password', 'trim|required|min_length[4]|max_leng[32]');
$this->form_validation->set_rules('password2', 'Password Confirmation','trim|required|matches[password]');
$this->form_validation->set_rules('captcha', 'Captcha','trim|required');}else{
$this->form_validation->set_rules('captcha', 'Captcha', 'callback_check_captcha');}

{ //this -> to the curr obj(UserController) && registraion() points to the the function in controller
$this->registration(); //reloads reg page so they can fill out right stuff

$this->form_validation->set_message('check_captcha', 'text dont match captcha');

The message name corresponds to the function, not the field. So setting it to "check_captcha" will fix your bug. The error message will use the correct field name.
