Im working on an interface for a custom post type where I need the post title to carry the date and venue name. So on the Admin end I've got js that dynamically populate the title as the user fills out the form. If the user dosen't languish this information is then saved as a part of the permalink. Sometimes however the post is saved as a draft before the title is populated and we end up with an misleading URL.
My feeling is that it would be best I were to just hide the title all together on this post type, and look for a hook to populate the title AND rework the post url with the field values the user has set when saving the post. As of now I cant find any hooks or filters that look like they would be of help.
