Php Codeigniter*多图像上传*保存到数据库问题

我可能错过了一个真正简单的要点，但你们中的一位Codeigniter大师是否能够帮助我解决我的问题。我有一个userform，用于存储销售页面的信息，该页面包含保存到数据库中的文本和图像

我可以很好地将一个图像保存到数据库中，但我很难将多个图像保存到数据库中。目前所有的图像都被转移到正确的文件夹，但我需要他们存储在MySQL表

表格：

控制器：

function add_aircraft()
{
   $this->load->library('form_validation');
  /* handle form data then send to model */
    $this->form_validation->set_rules('title', 'Title', 'trim|required');
    $this->form_validation->set_rules('price', 'Price', 'trim|required');
    $this->form_validation->set_rules('year', 'Year', 'trim|required');
    $this->form_validation->set_rules('annual', 'Annual', 'trim|required');
    $this->form_validation->set_rules('serial_number', 'Serial number', 'trim|required');
    $this->form_validation->set_rules('airframe_hours', 'Airframe hours', 'trim|required');
    $this->form_validation->set_rules('engine_type', 'Engine type', 'trim|required');
    $this->form_validation->set_rules('engine_hours', 'Engine hours', 'trim|required');
    $this->form_validation->set_rules('propeller_type', 'Propeller type', 'trim|required');
    $this->form_validation->set_rules('notes', 'Sales Pitch', 'trim|required');
    $this->form_validation->set_rules('avonics', 'Avonics', 'trim');
    $this->form_validation->set_rules('avonics1', 'Avonics', 'trim');
    $this->form_validation->set_rules('avonics2', 'Avonics', 'trim');
    $this->form_validation->set_rules('avonics3', 'Avonics', 'trim');
    $this->form_validation->set_rules('avonics4', 'Avonics', 'trim');
    $this->form_validation->set_rules('avonics5', 'Avonics', 'trim');
    $this->form_validation->set_rules('avonics6', 'Avonics', 'trim');
    $this->form_validation->set_rules('interior', 'Interior', 'trim|required');
    $this->form_validation->set_rules('exterior', 'Exterior', 'trim|required');
    $this->form_validation->set_error_delimiters('<div class="alert alert-error"><a class="close" data-dismiss="alert">×</a><strong>', '</strong></div>');
    if($this->form_validation->run() == FALSE)
    {
        $data['main_content'] = 'control/aircraftsales/add';
        $this->load->view('control/includes/template_simple_header_footer', $data);
        $name_array[] = $data['aircraft1'];
    }
    else
    {
        $this->load->model('control/Aircraftsales_model');

        if($this->Aircraftsales_model->add_aircraft()){
             $data['main_content'] = 'control/aircraftsales/add';
             $this->load->view('control/includes/template_simple_header_footer', $data);
        }
    }
}

模型这似乎是问题所在？？：

function add_aircraft()
{
    $name_array = array();
    $count = count($_FILES['userfile']['size']);
    foreach($_FILES as $key=>$value)
        for($s=0; $s<=$count-1; $s++)
        {
          $_FILES['userfile']['name']=$value['name'][$s];
          $_FILES['userfile']['type'] = $value['type'][$s];
          $_FILES['userfile']['tmp_name'] = $value['tmp_name'][$s];
          $_FILES['userfile']['error'] = $value['error'][$s];
          $_FILES['userfile']['size'] = $value['size'][$s];

          /* config image */
          $config['upload_path'] = './upload/aircraftsales';
          $config['allowed_types'] = 'gif|jpg|png';
          $this->load->library('upload', $config);
          $this->upload->initialize($config);

          $this->upload->do_upload();
          $data = $this->upload->data();

          $name_array[] = $data['file_name'];
          $names= implode(',', $name_array);
        }

        $aircraft = array(
            'title' => $this->input->post('title'),
            'price' => $this->input->post('price'),
            'year' => $this->input->post('year'),
            'annual' => $this->input->post('annual'),
            'serial_number' => $this->input->post('serial_number'),
            'airframe_hours' => $this->input->post('airframe_hours'),
            'engine_type' => $this->input->post('engine_type'),
            'engine_hours' => $this->input->post('engine_hours'),
            'propeller_type' => $this->input->post('propeller_type'),
            'notes'     => $this->input->post('notes'),
            'avonics'   => $this->input->post('avonics'),
            'avonics1'  => $this->input->post('avonics1'),
            'avonics2'  => $this->input->post('avonics2'),
            'avonics3'  => $this->input->post('avonics3'),
            'avonics4'  => $this->input->post('avonics4'),
            'avonics5'  => $this->input->post('avonics5'),
            'avonics6'  => $this->input->post('avonics6'),
            'interior'  => $this->input->post('interior'),
            'exterior'  => md5($this->input->post('exterior')),
           );

           $insert = $this->db->insert('aircraftsales', $aircraft);
           return $insert;
      }
 }

在代码中使用return$insert

返回充当退出。因此，当其到达时，它将停止foreach并立即将值返回给控制器

您无需在foreach循环中使用for循环

只需提及，我的图像db字段是'aircraft1'，'aircraft2'，'aircraft3'等等，我有四个。看看这是否有帮助@MichaelRodwell此代码是否包括您将图像插入数据库的代码？我在插入中没有看到与$names或$name\u数组的任何交互？出现了什么错误？
