尝试使用codeigniter获取非对象的属性，如在数据库表中找不到记录时在视图页面中显示该错误消息请解决我的问题（当数据库表单中没有找到的记录应该显示在视图页面中）

控制器

 public function buyerdetails_form() {
            $this->load->helper('url');

             $result = $this->Profile_model->buyer_details();
            $data['c_address']=$result->address;
            $data['c_pincode']=$result->pincode;
            $data['c_district']=$result->district;
            $data['c_city']=$result->city;
            $data['c_state']=$result->state;
            $data['c_country']=$result->country;
            $this->load->view('buyerdetails_form',$data);

    }

模型

public function buyer_details()
{
    $this->db->select('*');
    $this->db->from('customer_otherdetails');
    $this->db->where('customerid_fk', $this->session->id);
    $query = $this->db->get();
    $rows = $query->result(); //so you only have to call result once
    if($query->num_rows() > 0)
    {
        foreach($rows as $row)
        {
            //add all data to session
            $newdataa = array(
              'address' => $row->address,
              'pincode' => $row->pincode,
              'city' => $row->city,
              'district' => $row->district,
              'state' => $row->state,
              'country' => $row->country,
            );
        }
        $this->session->set_userdata($newdataa);
        //put the return outside the if
        //return $query->result();
    }
   // return $rows; //this will be an empty array if no data found
     return $query->row();

}
