I am having a custom block which uses the following code to fetch a list of comma separated posts.

    $numberposts = "7,9,5,10";
    $post_ids = explode( ',', $numberposts );
    $args = array( 
        'post_type' => 'post',
        'post__in' => $post_ids,
        'numberposts' => '9999999'
    $list_posts = get_posts( $args );

The problem is that the returned data is not ordered by the original order of the ids supplied. Is it possible to do that? Can you please help?


You can set the orderby to post__in. Here is a superior post loop:

$args = [
    'post__in' => [ 1, 2, 3, 4 ],
    'orderby'  => 'post__in',

$q = new \WP_Query( $args );
if ( $q->have_posts() ) {
    while ( $q->have_posts() ) {
        <article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
            <?php the_title(); ?>
} else {
    echo '<p>No posts found</p>';

Important changes:

  • get_posts does not fire all the loop lifecycle filters, bypasses caches by default ( suppress_filters is set to true in get_posts ), and doesn't set the current post for you. It also uses WP_Query internally, so I cut out the middleman and used WP_Query directly. This loop is both faster, more expandable, and more compatible
  • I removed numberposts and post_type, these are unnecessary and would actually slow down the query if WP used them. WP knows which posts you want via post__in so it'll just fetch those
  • orderby is set to post__in so posts will appear in the same order they're requested
  • I used a PHP array instead of using explode on a string ( which gives the same result so why do the extra work? )
  • I used the_ID and post_class so the inner loops tags would have the appropriate classes

I strongly recommend you read through this document: https://developer.wordpress.org/reference/classes/wp_query/ it will save a lot of time in the future and has a lot of examples.
