无法使用twilio将传入消息存储在我的数据库中

Question

我正在使用twilio发送短信。我可以发送短信，但是我不能接收传入的短信，也不能存储在数据库中。当我从客户那里收到短信到我的twilio号码时。我想从数字和正文中获取字段，然后保存到我的数据库中。 在下面的代码中，我给出了代码。请说明问题所在以及需要进行哪些更改以将数据存储在数据库中。

        </div>
        <section class="" style="margin-left: 25px;">

        </form>

        </section>
    </section>
</section>

控制器代码：

function receivesmsadd(){
        $data = array();
        $data['appointment_id']        = $this->input->post('appointment_id');
        $data['acceptance']            = $this->input->post('acceptance');
        $data['payment_method']        = $this->input->post('payment_method');
        $data['phone']                 = $this->input->post('phone');

        $this->load->model('patient_model');
        if ($this->patient_model->receivesms($data)) {
            $this->session->set_flashdata('message','Added Successfully');
        } else {
            $this->session->set_flashdata('message','Failed to Added');
        }     
    }

模式代码：

 function receivesms($data) {
        return $this->db->insert('receivesms',$data);
    }
