#50447 new defect (bug)

wp_publish_post not checking for unique post slugs

Reported by: hughie.molloy Owned by:

Severity: major Version: trunk
Component: Posts, Post Types Keywords: has-patch

When published a post using wp_publish_post no check is done to see if the slug / post_name is unique. This leads to problems with the permalink.

I have attached a patch file to the ticket as I could not make a PR to the github

Steps to reproduce:
Make and publish an article titled 'test'. ID 1
Make and set to draft a second article titled ' test'. ID 2

call wp_publish_post(2)
the post name of articles 1 and 2 are both set to test.

This can be worked around by calling the following code instead:


$post = [
    'ID' => 2,
    'post_status' => 'publish',

Making sure post name is unique when publishing article with wp_publish_post

When wp_publish_post is called there is no check to see if the slug (post_name) or the post is unique. This leads to multiple posts having the same URL.

Added a call to wp_unique_post_slug and setting the new slug on DB update to publish
