Changeset 48310 for trunk/src/wp-includes/post.php

Timestamp:

Message:

Post Thumbnails: Change the return value of get_post_thumbnail_id() for a non-existing post to false instead of an empty string.

This further makes the function more consistent with get_the_ID() or wp_get_post_parent_id(), both returning false for a non-existing post.

Additionally, document that get_post_thumbnail_id() returns 0 if the thumbnail image is not set.

Follow-up to [47160].

Props theMikeD, dingo_d, netpassprodsr, SergeyBiryukov.
Fixes #49832. See #40096.
