Class

SearchApiViewsHandlerFilterOptions

Views filter handler for fields with a limited set of possible values.

Code

function accept_exposed_input($input) {
  $accepted = parent::accept_exposed_input($input);

  // Grouped filters will have the raw form values structure from the
  // checkboxes as the value here. Convert that into the correct array of
  // values instead.
  if ($accepted && is_array($this->value) && $this
    ->is_a_group()) {

    // For some reason, Views thinks it's a good idea to nest the form values
    // into a second array in some cases. That one will be numerically indexed
    // with just a single entry, though, so it should be relatively easy to
    // spot.
    if (count($this->value) && isset($this->value[0])) {
      $this->value = reset($this->value);
    }
    $this->value = array_keys(array_filter($this->value));
    if (!$this->value) {
      return FALSE;
    }
  }
  return $accepted;
