get_object_term_cache()

get_object_term_cache() — Retrieves the cached term objects for the given object ID. Upstream functions (like get_the_terms() and is_object_in_term()) are responsible for populating the object-term relationship cache. The current function only fetches relationship data that is already in the cache.

Inputs: $id (int): Term object ID, for example a post, comment, or user ID. $taxonomy (string): Taxonomy name.

Returns bool|WP_Term[]|WP_Error: Array of WP_Term objects, if cached. False if cache is empty for $taxonomy and $id. WP_Error if get_term() returns an error object for any term.
