How to do that?

Hello I have a problem with my code

Code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Site extends CI_Controller{

public $name = 0;
public function upload_file()
{
  $status = "";
  $msg = "sunt din site";
  $file_name = "";
  $file_element_name = 'userfile';
  $config['upload_path'] = './files/';
  $config['allowed_types'] = 'gif|jpg|png';
  $config['max_size'] = 1024 * 8;
  $config['max_width'] = 300;
  $config['max_height'] = 215;
  $config['encrypt_name'] = TRUE;
  $this->load->library('upload', $config);
  if (!$this->upload->do_upload($file_element_name)){
   $status = 'error';
   $msg = $this->upload->display_errors('', '');  
  }else{
   $data = $this->upload->data();
   $msg = $data['file_name'];
   setname($msg);
   $file_name = $data['orig_name'];
  
   /*
   $this->load->model('upload');
   $file_id = $this->upload->insert_file(
   */
   @unlink($_FILES[$file_element_name]);
  }
}
public function setname($data){
  $this->name = $data;
}

The problems sounds like that, I`m making ajax uploading and i want to check the name of the file uploaded before, and for that i made a global pulic name and i want to set it but it doesn't work, how should i do that?
