Filter handler for boolean fields.

Code

public function get_value_options() {
  $field = field_info_field($this->definition['field_name']);
  $value_options = list_allowed_values($field);

  // Boolean fields have an option for using the label as the 'on' value. This
  // results in there being no label values in the allows values array.
  // If this is the case, we need to provide the labels.
  $filtered = array_filter($value_options);
  if (empty($filtered)) {

    // We can't provide the label in the same way the FieldAPI formatter does,
    // as these are different on each instance, and we may be operating on
    // more than one bundle.
    $value_options[0] = t('Off');
    $value_options[1] = t('On');
  }
  $this->value_options = $value_options;
