function template_preprocess_taxonomy_term

Prepares variables for taxonomy term templates.

Default template: taxonomy-term.html.twig.

By default this function performs special preprocessing to move the name base field out of the elements array into a separate variable. 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 associative array containing the taxonomy term and any fields attached to the term. Properties used:
  • #taxonomy_term: A \Drupal\taxonomy\TermInterface object.
  • #view_mode: The current view mode for this taxonomy term, e.g. 'full' or 'teaser'.
• attributes: HTML attributes for the containing element.

Code

function template_preprocess_taxonomy_term(&$variables) {
    $variables['view_mode'] = $variables['elements']['#view_mode'];
    $variables['term'] = $variables['elements']['#taxonomy_term'];
    
    /** @var \Drupal\taxonomy\TermInterface $term */
    $term = $variables['term'];
    $variables['url'] = !$term->isNew() ? $term->toUrl()
        ->toString() : NULL;
    // Make name 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 = $term->getEntityType()
        ->get('enable_base_field_custom_preprocess_skipping');
    if (!$skip_custom_preprocessing || !$term->getFieldDefinition('name')
        ->isDisplayConfigurable('view')) {
        // We use name here because that is what appears in the UI.
        $variables['name'] = $variables['elements']['name'];
        unset($variables['elements']['name']);
    }
    $variables['page'] = $variables['view_mode'] == 'full' && taxonomy_term_is_page($term);
    // Helpful $content variable for templates.
    $variables['content'] = [];
    foreach (Element::children($variables['elements']) as $key) {
        $variables['content'][$key] = $variables['elements'][$key];
