Changeset 47317 for trunk/tests/phpunit/tests/post.php

Timestamp:

02/19/2020 03:50:38 AM (5 years ago)

Author:

Message:

Posts, Post Types: Discard tags_input parameter in wp_update_post() if it's the same as existing post tags.

This ensures that wp_update_post() does not unintentionally modify post tags if the post has several tags with the same name but different slugs.

Tags should only be modified if tags_input parameter was explicitly provided, and is different from the existing tags.

Props kaggdesign, SergeyBiryukov.
Fixes #45121.
