Help Upload Library Please!

[eluser]Unknown[/eluser]
Hi all, I need help, i'm a newbie in CI.

I know that is inappropriate add a new method directly on a CI lib (in this case Upload).

Whatever, I have a problem.
The thing is i created a method to upload multiple files and works almost fine.
This method i added it to Upload CI class and when i called it from my 'Upload' controller (note: same name than CI Lib) it seems the Upload CI lib load twice!

The METHOD in my Upload CONTROLLER code:

Code:

function multiple_files_form()
    {
        if($this->phpauthent->is_logged_in())
        {
            $data['header'] = 'Ajax Upload';

            //Upload files with single element
            $data['extraHeadContent'] = "[removed] arrayExt = new Array('.pdf', '.jpeg', '.jpg', '.png', '.gif'); [removed]";
            $data['extraHeadContent'] .= "[removed][removed]";

            //Load Script Module
            $data['extraHeadContent'] .= "[removed][removed]";
            
            $config['upload_path'] = './uploads/';
            $config['allowed_types'] = 'pdf|jpeg|jpg|png|gif';
            $config['max_size']    = '100';

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

            if(isset($_FILES['files']))
            {
                if (! $this->upload->do_multiple_upload($_FILES['files']))//If there is some error...
                {
                    $data['errors'] = $this->upload->display_errors();

                    $this->load->view('upload_files', $data);
                }
                else
                {
                    if($this->upload->do_multiple_upload($_FILES['files']))//If is a succesfull upload...
                    {
                        echo implode(" / ", $this->upload->get_unique_file_names());
                        $success_data['sucess_message'] = 'Los archivos se han subido satisfactoriamente.';
                        $this->load->view('success', $success_data);
                    }
                }
            }
            else//If is the first time opening the form...
            {
                $data['errors'] = '';
                $this->load->view('upload_files', $data);
            }
        }
        else
        {
                redirect('/auth');
        }
    }

The method added into CI Upload Lib in the next post....
