我正在尝试使用代码点火器框架上传图像，因为我的控制器类代码如下
public function addNewSlider()
{
if($this->session->userdata('logged_in'))
{
$this->form_validation->set_rules('title','Title','required');
if($this->form_validation->run()===FALSE)
{
$data['content']=$this->input->get_post('content');
$data['file']=$this->input->get_post('file');
$data['status']=$this->input->get_post('status');
$this->load->view('admin/templates/header',array('sessionArray'=>$this->sessionArray));
$this->load->view('admin/sliders/addNewSlider',$data);
$this->load->view('admin/templates/footer');
}
else
{
/*$title=$this->input->get_post('title');
$content=$this->input->get_post('content');
$image=$this->input->get_post('file');
$status=$this->input->get_post('status');
$this->sliders_model->insertNewMenu($title,$content,$image,$status);
redirect('sliders','refresh');*/
}
}
else
{
redirect('index','refresh');
}
}
function do_upload()
{
$name=time();
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
// $config['max_size'] = '100';
// $config['max_width'] = '1024';
//$config['max_height'] = '768';
$config['file_name']=$name;
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload())
{
$error = array('error' => $this->upload->display_errors());
print_r($error);exit;
//$this->load->view('upload_form', $error);
}
else
{
$data = array('upload_data' => $this->upload->data());
//$this->load->view('upload_success', $data);
}
$config['image_library'] = 'gd2';
$config['source_image'] = './uploads/'.$name.'.jpg';
$config['new_image'] = './uploads/'.$name.'.jpg';
$config['create_thumb'] = FALSE;
$config['maintain_ratio'] = FALSE;
$config['width'] = 1000;
$config['height'] = 400;
$this->image_lib->resize();
$config['new_image'] = './uploads/'.$name.'.jpg';
$config['width'] = 1000;
$config['height'] = 400;
$this->image_lib->initialize($config);
$this->image_lib->resize();
$title=$this->input->get_post('title');
$content=$this->input->get_post('content');
$image=$name.'.jpg';
$status=$this->input->get_post('status');
$this->sliders_model->insertNewSlider($title,$content,$image,$status);
redirect('sliders','refresh');
}
**and my view file is code is as follows**

我的主要问题是，当我按下提交按钮错误消息时，您没有选择要上传的文件。显示。任何人都可以帮助我快速克服这个问题吗？
