Retrieves a post tag by tag ID or tag object.
Syntax Syntax
Description Description
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.
Parameters Parameters
- $tag
-
(Required) A tag ID or object.

Default value: OBJECT
- $filter

(Optional) How to sanitize tag fields. Default 'raw'.
Default value: 'raw'
Return Return
(WP_Term|array|WP_Error|null) Tag data in type defined by $output parameter. WP_Error if $tag is empty, null if it does not exist.
