       location = "../main/";
   [removed]';

  }
}

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class User_model extends CI_Model {

var $gallery_path;
var $gallery_path_url;


// Construct Method
function __construct()
{
      parent::__construct();
  $this->gallery_path = realpath(APPPATH . '../uploads');
  $this->gallery_path_url = base_url().'uploads/';
        
}

function reg($activation_code)
{
  $data = array(
    'username'=>$this->input->post('username'),

  return;

}
  
function do_upload() {
  
  $config = array(
   'allowed_types' => 'jpg|jpeg|gif|png',
   'upload_path' => $this->gallery_path,
   'max_size' => 2000
  );
  
  $this->load->library('upload', $config);
  $this->upload->do_upload();
  $image_data = $this->upload->data();
  
  $config = array(
   'source_image' => $image_data['full_path'],
   'new_image' => $this->gallery_path . 'uploads/thumbs',
   'maintain_ration' => true,
   'width' => 150,

  );
  
  $this->load->library('image_lib', $config);
  $this->image_lib->resize();
  
}

function get_images() {
  
  $files = scandir($this->gallery_path);
  $files = array_diff($files, array('.', '..', 'uploads/thumbs'));
  
  $images = array();
  
  foreach ($files as $file) {
   $images []= array (
    'url' => $this->gallery_path_url . $file,
    'thumb_url' => $this->gallery_path_url . 'uploads/thumbs/' . $file
   );
  }
  
  return $images;
