get_object_term_cache( int $id, string $taxonomy )
Retrieves the cached term objects for the given object ID.
Description 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 Parameters
- $id
-
(int) (Required) Term object ID, for example a post, comment, or user ID.
- $taxonomy
-
(string) (Required) Taxonomy name.
Return Return
(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.
