WordPress Development Stack Exchange is a question and answer site for WordPress developers and administrators. It's 100% free, no registration required.

I've been using WP for years, but this is my first time with taxonomies, so I need a little bit of help.

Like in the question How to show a hierarchical terms list? I have a taxonomy called places, which contains a hierarchical list of places (first level for countries, second level for cities, etc...).

A post can have an associated place: for example, we could take Berlin (child of Germany, child of Europe).

Now, the output I want is something like this:

Where: Berlin, Germany, Europe.

I've tried some solutions, but none works. I'm pretty sure that there must be a simple and clean solution...

wp_get_object_terms will give you the term assigned to the post, you could then use get_ancestors to get an array of the parent's IDs, then get_term_by ID to get the names and slugs.
