Question

我正在尝试一次上传多个图片，但此代码包含错误，错误消息显示未定义索引：photo1A。所以帮我解决一下。

function add_student_database(){

  //echo '<pre>';print_r($_POST);print_r($_FILES);exit;
  $this->load->library('upload');


  if($this->input->post('stu_class')=='first' && $this->input->post('section')=='A')
  {
     $data = $this->input->post('student1A');
     $img_data = $_FILES['photo1A'];
    // echo '<pre>';print_r($_FILES);exit;
     $count = count($_FILES['photo1A']);
        $config['upload_path'] = './upload/';
        $config['allowed_types'] = 'jpg|png|gif';
        $config['max_size'] = '100000';
        $config['max_width'] = '2000';
        $config['max_height'] = '2000';
     $this->load->library('upload', $config);
     for($i=0;$i<$count;$i++)
     {

        $_FILES['photo1A']['name'] = $img_data['photo1A']['name'][$i];
        $_FILES['photo1A']['type'] = $img_data['photo1A']['type'][$i];
        $_FILES['photo1A']['tmp_name'] = $img_data['photo1A']['tmp_name'][$i];
        $_FILES['photo1A']['error'] = $img_data['photo1A']['error'][$i];
        $_FILES['photo1A']['size'] = $img_data['photo1A']['size'][$i];

        $this->upload->initialize($config);
        $this->upload->do_upload('photo1A');
     }

     $section = "A";
     $stu_class = "class1";

  }
  elseif($this->input->post('stu_class')=='first' && $this->input->post('section')=='B')
  {
     $data = $this->input->post('student1B');
     $section = "B";
     $stu_class = "class1";

  }
  elseif($this->input->post('stu_class')=='second' && $this->input->post('section')=='A')
  {
     $data = $this->input->post('student2A');
     $section = "A";
     $stu_class = "class2";

  }
  elseif($this->input->post('stu_class')=='second' && $this->input->post('section')=='B')
  {
     $data = $this->input->post('student2B');
     $section = "B";
     $stu_class = "class2";

  }

  $this->marksheet_data->get_data($data, $section, $stu_class);
}
