update_object_term_cache() WP 2.3.0

Updates the cache for the given term object ID(s).

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.

Хуков нет.

Возвращает

null/false. False if all of the terms in $object_ids are already cached.
