I want to make the slug for each of my custom post types to be the post ID number. How do I do this? None of my posts accept post title, content, or anything else - they require different data which was easier to display as a meta box). To illustrate:
I have a CPT ('eduation'). When I submit the post into the database, it has an ID of, say, 15. When I visit mysite.com/edu/15 ('edu' being the post slug that I have set), I see the details from this post in my site.
I know I could simply change the permalinks, but I want those to stay as they are; I just want to change the ones for these custom post types. Sorry if the question is confusing. It probably is really simple to answer, but I really don't know what the answer is.
