此处为控制器页面，此处为图像名称插入到数据库中，但图像未进入相应的目录

您应该这样尝试

$config['upload_path']   = './upload/';
$config['allowed_types'] = 'gif|jpg|png|jpeg|pdf|mp4';         

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

if(!$this->upload->do_upload('picture'))
 {
    $error = array('error' => $this->upload->display_errors());
     print_r($error);
 }
 else{
    $data = array('upload_data' => $this->upload->data());
    print_r($data);
  }

删除
$this->upload->initialize（$config）行。如果在装入类时传递第二个参数，您不需要使用配置数组初始化类。@Tpojka因此在上载目录中没有filgets您没有使用上载函数，但希望上载文件？我没有使用do\u uploadfunction@jibinkj然后您需要使用@Mayank Vadiya，因此没有输出确保您上传的目录有适当的权限
