get_tag() WP 2.3.0

Retrieves a post tag by tag ID or tag object.

If you pass the $tag parameter an object, which is assumed to be the tag row object retrieved from the database, it will cache the tag data.

If you pass $tag an integer of the tag ID, then that tag will be retrieved from the database, if it isn't already cached, and passed back.

If you look at get_term(), both types will be passed through several filters and finally sanitized based on the $filter parameter value.

Хуков нет.

Возвращает

WP_Term/Массив/WP_Error/null. Tag data in type defined by $output parameter. WP_Error if $tag is empty, null if it does not exist.
