Code

protected function hasValidGroupedValue(array $group) {
  if (!is_array($group['value']) || empty($group['value'])) {
    return FALSE;
  }
  // Special case when validating grouped date filters because the
  // $group['value'] array contains the type of filter (date or offset) and
  // therefore the number of items the comparison has to be done against is
  // one greater.
  $operators = $this->operators();
  $expected = $operators[$group['operator']]['values'] + 1;
  $actual = count(array_filter($group['value'], 'static::arrayFilterZero'));
