function template_preprocess_aggregator_feed

Prepares variables for aggregator feed templates.

Default template: aggregator-feed.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_feed(&$variables) {
    $feed = $variables['elements']['#aggregator_feed'];
    // Helpful $content variable for templates.
    foreach (Element::children($variables['elements']) as $key) {
        $variables['content'][$key] = $variables['elements'][$key];
    }
    $variables['full'] = $variables['elements']['#view_mode'] == 'full';
    // 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 = $feed->getEntityType()
        ->get('enable_base_field_custom_preprocess_skipping');
    if (!$skip_custom_preprocessing || !$feed->getFieldDefinition('title')
        ->isDisplayConfigurable('view')) {
        $variables['title'] = $feed->label();
    }
