我的票务系统处于活动状态。我想要的是,当用户从chrome登录时,如果他再次尝试从firefox登录而又未从chrome登录,那么chrome帐户将自动退出。

这是我的控制器代码:-

public function loginSubmit() {
        if($this->session->userdata('is_logged_in')==true){
            $sessionData = $this->session->all_userdata();
            $userId = $sessionData['id'];
            redirect('auth/welcome');
        }
        else{
                $userId = $this->input->post('id');
                $u_data = array (
                    'id' => $userId,
                    'is_logged_in' => TRUE
                );
                $this->session->set_userdata($u_data);
                $sessionId = session_id();
                $this->auth_model->setSession($userId,$sessionId);
                redirect('auth/welcome');
                $this->login();
        }
    }

这是我的模型代码:-

public function setSession($userId, $sessionId) {
        $data1 = array(
            'id' => $userId
        );
        $oldSessionId = $this->db->select("session_id")
                ->where($data1)
                ->get("client_sign_up")
                ->row('session_id');
        print_r($oldSessionId);
        $data = array(
            'id' => $oldSessionId
        );
        $this->db->where('id',$data)
                ->delete('ci_sessions',$u_data);
        $this->db->where('id', $userId)
                ->update('client_sign_up', array('session_id' => $sessionId));
    }
