Problem with updating session data

PHP Code:

private function setLoginData($data,$ifAutoLog=0){
        if(is_object($data)){
                if($data->user_status==0){
                    $this->CI->session->set_flashdata('msg_error','Error');
                    return FALSE;   
                }

                $s_data = array(
                    's_userid'   => $data->user_id,
                    's_username' => $data->user_name, 
                    's_loggedin' => TRUE
                );            
                $this->CI->session->set_userdata($s_data);

                $sesjaId = session_id();
                $dataEd = array("user_id" => $data->user_id);
                $this->CI->db->update('ci_sessions_2', $dataEd, array('id' => $sesjaId));
                                
                if($ifAutoLog==1){
                    $this->deleteToken($data->user_id);
                    $newToken = $this->genAutologToken();
                    $dataAdd = array(
                        'user_id'   => $data->user_id,
                        'token'     => $newToken
                    );
                    $this->CI->db->insert('ci_users_rem', $dataAdd);
                    $idToken = $this->CI->db->insert_id();
                    $this->setAutoLogCookie($idToken,$newToken);
                }
                
                return TRUE;
        } 
        else{
            return FALSE;
        }
    }
