$CI =& get_instance();
$base_path = $CI->config->slash_item('base_path');
  
    
$this->load->library('upload');
$rand=rand(0,100000);

     for($i=0;$i<count($_FILES['file_up']['name']);$i++)
     {  
  $_FILES['userfile']['name']    =   $_FILES['file_up']['name'][$i];
  $_FILES['userfile']['type']    =   $_FILES['file_up']['type'][$i];
  $_FILES['userfile']['tmp_name'] =   $_FILES['file_up']['tmp_name'][$i];
  $_FILES['userfile']['error']       =   $_FILES['file_up']['error'][$i];
  $_FILES['userfile']['size']    =   $_FILES['file_up']['size'][$i];
  
  $config['file_name']     = $rand.'user_'.$i;
  $config['upload_path'] = 'upload/orig/';
