Views Search API area handler

Class

views_handler_area_spellcheck

Area handlers are available to be placed in a views header and footer. Spelling suggestions will only display if some are returned with the results.

Code

function render($empty = FALSE) {
  $results = $this->query
    ->getSearchApiResults();

  // if no spellcheck results are returned then return
  if (!isset($results['search_api_spellcheck'])) {
    return '';
  }

  // Loop through the filters and find any text searches as these may be
  // related to the returned spelling suggestions
  $get = array();
  foreach ($this->view->filter as $key => $filter) {
    if ($filter instanceof SearchApiViewsHandlerFilterFulltext) {

      // We need to pass the key names to the theme function.
      // theme_search_api_spellcheck() can return one or more links with
      // spelling suggestions. These links need to direct the to user back to
      // the same filtered page but with only the origional filter key changed
      // to the suggestion.
      $get[] = $filter->options['expose']['identifier'];
    }
  }
  $variables = array(
    'spellcheck' => $results['search_api_spellcheck'],
    'options' => array(
      'get' => $get,
    ),
  );
  return theme('search_api_spellcheck', $variables);
}
