function template_preprocess_aggregator_item in Drupal 9

Same name and namespace in other branches

1. 8 core/modules/aggregator/aggregator.theme.inc \template_preprocess_aggregator_item()
2. 6 modules/aggregator/aggregator.pages.inc \template_preprocess_aggregator_item()
3. 7 modules/aggregator/aggregator.pages.inc \template_preprocess_aggregator_item()

Prepares variables for aggregator item templates.

Default template: aggregator-item.html.twig.

By default this function performs special preprocessing to create a separate variable for the title base field. This preprocessing is skipped if:

• a module makes the field's display configurable via the field UI by means of BaseFieldDefinition::setDisplayConfigurable()
• AND the additional entity type property 'enable_base_field_custom_preprocess_skipping' has been set using hook_entity_type_build().

Parameters

array $variables: An associative array containing:

• elements: An array of elements to display in view mode.

Code

function template_preprocess_aggregator_item(&$variables) {
  $item = $variables['elements']['#aggregator_item'];

  // Helpful $content variable for templates.
  foreach (Element::children($variables['elements']) as $key) {
    $variables['content'][$key] = $variables['elements'][$key];
  }
  $variables['url'] = UrlHelper::stripDangerousProtocols($item
    ->getLink());

  // Make title field available separately.  Skip this custom preprocessing if
  // the field display is configurable and skipping has been enabled.
  // @todo https://www.drupal.org/project/drupal/issues/3015623
  //   Eventually delete this code and matching template lines. Using
  //   $variables['content'] is more flexible and consistent.
  $skip_custom_preprocessing = $item
    ->getEntityType()
    ->get('enable_base_field_custom_preprocess_skipping');
  if (!$skip_custom_preprocessing || !$item
    ->getFieldDefinition('title')
    ->isDisplayConfigurable('view')) {
    $variables['title'] = $item
      ->label();
  }
