I have a custom post type for which I would like to disable saving as draft functionality. I don't think about autosave/revisions, just disabling drafts. Only publishing should be allowed.
Also, no CSS and/or plugins should be used.
Basically the reason I wanted to disable post drafts was because drafts don't require all fields to be filled. I need all fields to be mandatory regardless of the post status. If there is any solution for making fields mandatory I would be grateful. It doesn't have to be disabling drafts.
