update_object_term_cache( string|array $object_ids, array|string $object_type )
Updates the cache for the given term object ID(s).
Description
Note: Due to performance concerns, great care should be taken to only update term caches when necessary. Processing time can increase exponentially depending on both the number of passed term IDs and the number of taxonomies those terms belong to.
Caches will only be updated for terms not already cached.
Parameters
- $object_ids
-
(Required) Comma-separated list or array of term object IDs.
- $object_type
-
(Required) The taxonomy object type.
Return
(void|false) False if all of the terms in $object_ids are already cached.
