#34865 closed defect (bug) (fixed)

Slug reset when updating post without slug field

Reported by: jason_the_adams Owned by: ericlewis
Milestone: 4.5 Priority: normal

Currently, when a post is being updated, it's assumed that the existing post slug will be supplied with the post being updated, rather than retrieving the post and using the existing slug. Other values of the post aren't imposed, so it's fair to omit them in the update data. It seems like it would be consistent to retrieve the existing slug in wp_insert_post when updating.

If this makes sense, I'm happy to put together a test for proof-of-issue and subsequent fix.

I'm used to clearing the slug field and clicking "OK" to reset the post's slug, for example when I made a typo. I don't think I've ever cleared the slug field and hit "Update", but I guess changing this behaviour would break a couple of things.

#4 @jason_the_adams

@swissspidy Thanks for replying! There's a difference between the slug being offered as an empty string (what you're describing), and being omitted entirely (what I'm talking about). Since the slug is necessary, it makes perfect since that if it's an empty string, that it needs to be generated. But in the case that it's omitted AND is an update, then the existing slug shouldn't be changed -- at least that's what I'm proposing. In that case, I don't think it should break anything. Admittedly, it's a pretty niche bug.

See also #20419 (ping @mintindeed), which has to do with differentiating between post properties passed to the function differing from those in the database.

#6 @jason_the_adams

@boonebgorges I don't think to two are actually related. I'm including a patch as well as a test to present the issue.

(Thanks for the help, @jgrodel!)

I didn't want to overextend this. But I did notice as well that a similar issue happens if the post_status is omitted. In fact, there's two points in wp_insert_post that effectively forces 'draft' if the status is omitted or empty. It really feels like update should accept partial data and assume the existing data in that case.

  • Resolution set to fixed
  • Status changed from assigned to closed

In 35800:

Posts: Don't modify post_name if it wasn't supplied to wp_insert_post().

Previously when updating a post using wp_insert_post(), post_name was
regenerated based on post_title every time if post_name was not passed in
explicitly. This irons out the expectation that properties not passed into the
function should not be modified.

Props jason_the_adams.
Fixes #34865.
