Changeset 30141 for trunk/src/wp-includes/taxonomy.php

Timestamp:

11/01/2014 02:57:31 AM (10 years ago)

Message:

Allow resource_type to be specified in get_ancestors().

Being explicit about resource type (taxonomy vs post_type) allows for the
proper resolution of conflicts when a taxonomy and post_type share a slug.

Props filosofo.
Fixes #15029.
