Description

In order to preview an unpublished post (ie. draft or pending), a user needs the edit_posts capability for that post type (src).

There is a valid use case where a site requires a user role which has the capability to preview unpublished posts but not edit them, for example for editorial review/sign-off, layout review, early access, etc.

You can get around this by using a combination of the posts_results and the_posts filters, but this isn't very future-proof because the post results skip a bunch of logic that occurs between those two filters.

A preview_post meta capability and a preview_posts primitive capability could be introduced and implemented wherever the edit_posts capability is used in regard to previewing unpublished posts. By default, it will simply map to the edit_posts capability.

Thoughts?

I think this could definitely be useful, especially with publishing shops that may not want to rely on a plugin for their editorial flow.

For implementation, would this be a checkbox on the user's profile page that is set by someone with a specific (filterable) capability (read-only for everyone else, maybe?) or would it be enabled through a hook, or some other way I haven't thought of?

Replying to morganestes:

I think the most elegant way to do it would be to just give it to users who current have edit_posts by default, along the lines of the sub-cap concept (see the customize cap), thereby making it possible to programmatically remove the cap rather than add it.

This turns out to be more complicated that it first seems.

After patching several places in core with a preview_post capability check, I realised that previewing draft posts is a very different action to previewing changes to published posts, but they're both called previews.

We might need a collection of caps such as preview_published_posts, preview_others_posts, etc.

@johnbillion Will you have time to tackle this again properly any time soon? It'd be a great feature for multi-user Wordpress installations everywhere.

I'd love to, but I won't have time to tackle it in the next few months due to other commitments.

All of these are part of a larger goal.
