How to Write a WP_Query for Multiple Specific Post IDs
Recently, a client project I’m working on required something I don’t think I’ve done before: write a
WP_Query to fetch a dynamically generated list of post IDs.
The accepted answer in this Stack Exchange article tells you all you need to know about the answer: the
post__in (note the two underscores!) array key. Here’s the key bit that should be present in the
// Array of post IDs, generated however $ids = array( 11, 63, 157 ); $args = array( 'post__in' => $ids ); $query = new WP_Query( $args );
The only thing I’ll reiterate is, as always, to make sure you use the
post_type argument to input the post types you want to query for if you’re not just fetching
WP_Query only looks for
posts by default. If not, you’ll wonder why your well-written query is coming up empty.
