On my Auth library I need it to update my active column on my dataabase when session expire.
Currently if session expired and refreshes page it triggers my $this->auth->logout() function
But does not update the users active column to 0? It unsets user id fine and token fine but not update active column.
Question: When the session has expired how can I make sure it updates the users active column on database to 0

PHP Code:

$udata = array(
'active' => '0',
);
$this->CI->db->where('user_id', $this->CI->session->userdata('user_id'));
$this->CI->db->update($this->CI->db->dbprefix . 'user_data', $udata);
unset($_SESSION['user_id']);
unset($_SESSION['token']);
$this->user_id = '';
$this->username = '';
}
