我试图在mysql数据库中插入图像和其他数据，但它显示错误。它显示未保存的$msg&视图文件的重复数据可能是由于我设置的$error。ps:我在数据库中设置了'image'数据类型varchar。这是我的视图文件：

<input type="file" class="form-control-file" name="image" id="exampleInputFile" >

这是我的控制器：

public function save()
{
  $this->load->model('Partner_model');
 $feature = $this->input->post('feature');
  $config['upload_path']          = './uploads/files';
           $config['allowed_types']        = 'gif|jpg|png';
           $config['max_size']             = 100;
           $config['max_width']            = 1024;
           $config['max_height']           = 768;
           $this->load->library('upload', $config);
           if ( ! $this->upload->do_upload('image'))
{
       $error = array('error' => $this->upload->display_errors());
       $this->load->view('partner_profile', $error);
}
else
{
  $user_data= array(
   'pname' => $this->input->post('pname'),
   'type' => $this->input->post('type'),
   'address' => $this->input->post('address'),
   'about' => $this->input->post('about'),
   'city' => $this->input->post('city'),
   'code' => $this->input->post('code'),
   'state'=>$this->input->post('state'),
//  'image'=>$this->upload->do_upload('image')
  'feature'=>implode(",",$feature),
   'image' => $this->upload->data()
    );  
   }
    if($this->Partner_model->save($user_data))
   {
       $msg = "save sucesss" ;
   }
   else
   {
       $msg = "not save";
   }
   $this->session->set_flashdata('msg', $msg);
   $this->load->view('partner_profile');
 }
}

&这是我的模型：

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