Question

首先对于带有代码的长篇文章感到抱歉，但我觉得我需要直接解释自己。问题是，我正在尝试将一些数据插入数据库，并在RESTAURANT_IMAGE列中插入文件名。一切都很好地插入，但图像没有上传，文件名也没有插入数据库。

编辑：编辑回调函数以正确返回True或False，如果回调返回true，现在我在main函数中执行插入操作。现在我能够成功上传图像，但仍然没有将文件名和扩展名放到我的数据库中。

    function restaurant_add()
{
    $this->load->helper(array('form', 'url'));

    $this->load->library('form_validation');

    $config = array(
                                        array(
                                         'field'   => 'RestaurantName',
                                         'label'   => 'Restaurant Name',
                                         'rules'   => 'required|callback_restaurant_check'
                                        ),
                                        array(
                                         'field'   => 'RestaurantAddress',
                                         'label'   => 'Address',
                                         'rules'   => 'required'
                                        ),
                                        array(
                                         'field'   => 'RestaurantReservations',
                                         'label'   => 'Reservations',

                                         'label'   => 'RestaurantWifi',
                                         'rules'   => 'max_length[1]|integer'
                                        ),
                                        array(
                                            'field'   => 'RestaurantDelivery',
                                            'label'   => 'Restaurant Delivery',
                                            'rules'   => 'max_length[1]|integer'
                                         ),
                                        array(
                                            'field'   => 'RestaurantMultibanco',
                                            'label'   => 'RestaurantMultibanco',
                                            'rules'   => 'max_length[1]|integer'
                                        ),
                                        array(
                                                'field'   => 'RestaurantImage',
                                                'label'   => 'RestaurantImage',
                                                'rules'   => ''
                                                 )
                                        );

            $this->form_validation->set_rules($config);

            if ($this->form_validation->run() == FALSE)
            {
                $this->load->view('sample_navbar_view');
                $this->load->view('restaurant_add');
                return FALSE;
            }
            else
            {
            $file_name = $this->do_upload();
                $data = array(
     'RESTAURANT_NAME' => $this->input->post('RestaurantName'),
     'RESTAURANT_ADDRESS' => $this->input->  post('RestaurantAddress'),
     'RESTAURANT_RESERVATIONS'=> $this->input->  post('RestaurantReservations'),
     'RESTAURANT_WIFI'=> $this->input->  post('RestaurantWifi'),
     'RESTAURANT_DELIVERY'=> $this->input->  post('RestaurantDelivery'),
     'RESTAURANT_MULTIBANCO'=> $this->input->    post('RestaurantMultibanco'),
     'RESTAURANT_OUTDOOR_SEATING'=> $this->input->   post('RestaurantOutdoorSeating'),
     'RESTAURANT_IMAGE'=> $file_name
);
        $this->load->model('restaurant_model');
       $this->restaurant_model->restaurant_add($data);

                return TRUE;
            }
}

回调函数检查餐馆名称是否存在，如果存在，则不会注册，如果它没有将数据发送到模型中。

function restaurant_check($restaurantname){
    $this->load->model('restaurant_model');
    $result = $this->restaurant_model->check_restaurant_name($restaurantname);

    if($result > 0) {
        return FALSE;
}
    else    {
            return TRUE;
        }
 }

我使用了Codeigniter Documentation中的上传文件。

编辑：型号代码：

     function restaurant_add($info)
{
  $query =
                "INSERT INTO RESTAURANTS
                (RESTAURANT_NAME,RESTAURANT_ADDRESS,RESTAURANT_RESERVATIONS,

    $result = $this->db->query($query);

            $this->db->trans_rollback();
    }
    else
    {
            $this->db->trans_commit();
    }
return $rows;
}

do_upload（）函数：

    public function do_upload()
 {
             $config['upload_path']          = './assets/images/restaurantes';
             $config['allowed_types']        = 'gif|jpg|png';
             $config['max_size']             = 2000;
             $config['max_width']            = 1024;
             $config['max_height']           = 768;

             $this->load->library('upload', $config);

             if ( ! $this->upload->do_upload('userfile'))
             {
                             $error = array('error' => $this->upload->display_errors());

                             $this->load->view('success_view', $error);
             }
             else
             {
                             $data = array('upload_data' => $this->upload->data());

                             $this->load->view('upload_success', $data);
             }
             $upload_data = $this->upload->data();
            //Returns array of containing all of the data related to the file you uploaded.
                            $file_name =  $this->upload->file_name;
    return $file_name;
}
