Juicebox XML loader that's used to load (and build via loaded methods) the XML associated with a Drupal views style formatter plugin.

Class

JuiceboxXmlViewsStyle

Class to load and build the XML associated with a Drupal views style formatter plugin.

Code

public function getXml() {

  // Execute the view and build the gallery. This is easiest to do by simply
  // calling the preview() method (as it handles all needed sub-processes).
  $this->view
    ->preview($this->viewDisplay, $this->viewArgs);

  // See if if the galley is actually built. The preview() method above
  // typically triggers the Juicebox init and build processes, but under
  // certain caching situations these may be skipped (e.g., if the raw view
  // html is returned from a cache instead of calling the formatter logic).
  $juicebox = $this
    ->getJuiceboxFromData($this->view);
  if (!$juicebox) {

    // Build the gallery manually via the formatter's render method.
    $this->view->style_plugin
      ->render();

    // If we still don't have a built gallery something is wrong.
    $juicebox = $this
      ->getJuiceboxFromData($this->view);
    if (!$juicebox) {
      throw new Exception(t('Could not get gallery XML from view because the gallery could not be built.'));
    }
  }

  // Render the XML.
  return $juicebox
    ->renderXml();
