Taxonomy term breadcrumb; how?

Question

Given a taxonomy term (perhaps in a taxonomy*.php template) how to construct a breadcrumb going up the full ancestry of the term?

Is there any shorter way other than a "brute-force" loop to query current term's parent -> query term's parent -> query term's parent etc.?

Answer 1

You can use get_ancestors for this:

get_ancestors( $term_id, 'taxonomy' );

Of course this will only work on hierarchical elements. Additionally, this will only work reasonably well if only one term per level is assigned, take a look at my comment here and my answer here to get a little bit deeper insight into that.
