Changeset 50127 for trunk/tests/phpunit/tests/post/template.php

Message:

Posts, Post Types: Introduce new functions for determining if a post has a parent (has_post_parent()) and to fetch the post parent (get_post_parent()).

These functions are simple but reduce the logic needed in themes and plugins.
