Description
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.
Parameters
$idintrequired- Term object ID, for example a post, comment, or user ID.
$taxonomystringrequired- Taxonomy name.
