uploading picture

Okay, I change something:


config/config.php

PHP Code:

$config['base_url'] = 'http://127.0.0.1/CompanyGiondaCI/'; 


controllers/Cuploadfile.php
  

PHP Code:

  //file upload function
    function upload()
    {
        //set preferences
        $config['upload_path'] = './uploads/';
        $config['allowed_types'] = 'jpg|gif';
        $config['max_size']    = '500000';

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

        if (!$this->upload->do_upload('filename'))
        {
            // case - failure
            $upload_error = array('error' => $this->upload->display_errors());
            $this->load->view('addslideshows', $upload_error);
        }
        else
        {
            // case - success
            $upload_data = $this->upload->data();
            $data['success_msg'] = '<div class="alert alert-success text-center">Your file <strong>' . $upload_data['file_name'] . '</strong> was successfully uploaded!</div>';
            $this->load->view('addslideshows', $data);
        }
    }
