Next and previous posts with same ccap?

I’ve tried to solve this before, but I’m still banging my head against a wall. Any help is appreciated.

I have several posts protected by the same ccap. I’m trying to show a next/previous navigation that goes among those posts only, without including any other posts at all. I don’t need to worry if the user has permission to access them, just that the next/prev links only show posts with the same ccap.

Any help on how I could accomplish that? It’s such a niche question that I’m having trouble finding anyone, anywhere on the internet that knows.

Thank you!

Well, you’d need to query the db to find the posts with that ccap, sort them to know the order, and then you’ll have the previous and next one to the one being viewed.

Currently there isn’t a function to query these that way, so you’ll need to code this one yourself.

A simpler approach, though, may be adding to every post, a tag that matches the ccap. Then you have the tags navigation and functions available.

I hope that helps. :)

Thanks Cristián. Could you give me a clue about how to get the ccap of the current post? I think I can figure the rest out.

If you query the wp_postmeta table WHERE post_id = ‘$post_id’ AND meta_key = ‘s2member_ccaps_req’, you’ll get a row that contains a meta_value column containing a serialized array, which will contain the Custom Capabilities that are required to access that post. (e.g., a:1:{i:0;s:18:”my_custom_capability”;}).

Thank you!

Glad to help! :)
