 class Import_data extends CI_Controller
 {
   function __construct() 
   { 
    parent::__construct(); 
    //$this->load->helper('url');
    //$this->load->helper('form');
    $this->load->library('upload');
   } 
  function index()
  { 

  }
 function image_upload()
  {

        $config['upload_path'] = './upload';
        $config['allowed_types'] = 'gif|jpg|png|jpeg';
        $config['file_name'] = 'photo_' . substr(md5(time()), 0, 16);
        $image = 'aaa';
        $this->upload->initialize($config);
        if (!$this->upload->do_upload($image))
        {
            $error = array('error' => $this->upload->display_errors());
            print_r($error);die;
            $this->load->view('home_view', $error);

        }
        else
        {   
            $data = $this->upload->data();
            print_r($data);die;
            $this->load->view('upload_success', $data);
        }
    }
