I am using a template to display my attachments, with their metadata, and the site I’m building requires a lot of standalone media. Whenever someone sets a page thumbnail, or connects a post object to a page using ACF custom fields, the media becomes attached to that page. This changes the URL, and the breadcrumb, and breaks some other functions I wrote.
If I go into the media library, and unattach media in bulk, this has no effect on how media displays. My post thumbnails are still there, and so are my ACF values. So I would like everything to always be unattached. Is there a way to disable attaching, or trigger all media to have a parent of 0?
