Code

function _hs_process_determine_hsid($element, &$form_state) {

  // Determine the HSID to use: either the existing one that is received, or
  // generate a new one based on the last HSID used (which is
  // stored in form state storage).
  if (!isset($element['#value']) || !is_array($element['#value']) || !array_key_exists('hsid', $element['#value'])) {
    $hsid = uniqid();
  }
  else {
    $hsid = check_plain($element['#value']['hsid']);
  }
  return $hsid;
