#33386 closed defect (bug) (fixed)

Media GUID should never be treated as the filename or URL

Right now, there's a bunch of code in core (especially around display) that assumes a media item (attachment post) has a GUID which points to the URL. One instance of this was fixed in #32531, but others still exist.

This is problematic in at least two circumstances I can think of:

  1. If you change GUIDs to be a different system than just the permalink, this breaks media. For example, using UUIDs instead will give things like urn:uuid:f468f435-80bd-4709-bb52-f5c3e782a2ac in your media library.
  2. If you import media from another site, the filename may change, and the URL almost certainly will. Right now, the importer updates the GUID, which is a pretty big no-no. This has the potential to break all sorts of things.

These should be switched from $attachment->guid to get_attached_file( $attachment->ID ) instead.

Don't ever use the guid value when retrieving URLs for media, use wp_get_attachment_url(). Use get_attached_file() for path to file.

hey @wonderboymusic, I think #33319 is related to this also no?
