  • Since $parent is an array of parent terms keyed by the term id I went with reset(array_keys($parent)) if there's a better way please let me know.
  • For now loadParents() seems the only option, but $term->parent->target_id support can be added in drupal.org/node/2543726
  • Your $parent variable contains a Term object. You should use the $parent->id() method to get its tid.
  • Was that always there? I don't know how I missed it. Thanks.
  • How can I implement this? Does this go in theme preprocess_node. Can I create a variable from this so that I can use the variable in a twig template?
  • yeah, you can use in most of the available preprocesses as preprocess_node, preprocess_page, preprocess_theme, preprocess_route and so on.
