private function upload_files($path, $title, $files)
{
$config = array(
'upload_path' => $path,
'allowed_types' => 'jpg|gif|png',
'overwrite' => 1,
);
$this->load->library('upload', $config);
$images = array();
foreach ($files['name'] as $key => $image) {
$_FILES['images[]']['name']= $files['name'][$key];
$_FILES['images[]']['type']= $files['type'][$key];
$_FILES['images[]']['tmp_name']= $files['tmp_name'][$key];
$_FILES['images[]']['error']= $files['error'][$key];
$_FILES['images[]']['size']= $files['size'][$key];
$fileName = $title .'_'. $image;
$images[] = $fileName;
$config['file_name'] = $fileName;
$this->upload->initialize($config);
if ($this->upload->do_upload('images[]')) {
$this->upload->data();
