How to display 3 previous posts in article page?

Question

Does anyone know how to display 3 previous posts on article page? Let's say I'm in article post page and would like to display previous 3 posts images (basing on the post I'm currently reading) below it's content, but not next posts images . I was trying to do this with setting up the offset in the db query but with no luck. Can someone please help me with this one? I would greatly appreciate any help or at least pointing me in the right direction.

Answer 1

That shouldn't be too hard, if you use an id field with auto increment values, you could do something like this:

SELECT id, name FROM articles WHERE id < {current_id} ORDER BY id DESC LIMIT 3;

Obviously, replace {current_id} with the id of the article you're currently reading.

Answer 2

After displaying the specific post do a new WP_Query to retrieve the 3 posts previous to the publication date of the displayed post. This documentation page describes how to query for posts with a relative date (eg the example Return posts from the last 30 days ). Base the query on the publication time of the displayed post.

The example includes a way to supply a WHERE clause to the query, with add_filter(). I'm not sure, but I think you need to call remove_filter after doing the query, or that filter might be applied to other queries also.
