I have the same problem, this is my code, what’s wrong?
<?php
$ids = get_field('correla_blog_post');
$query = new WP_Query(array(
'post_type' => get_post_type(),
'posts_per_page' => 1,
'post__in' => $ids
));
if( $ids ): ?>
<div class="posts-list clearfix">
<?php foreach( $ids as $post): // variable must be called $post (IMPORTANT) ?>
<?php setup_postdata($post); ?>
<article class="post-item">
<figure><a href="<?php the_permalink(); ?>"><?php the_post_thumbnail('t300x200'); ?></a></figure>
<h2><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h2>
<div class="entry-excerpt"><p><?php the_field('riassunto_per_anteprima'); ?></p></div>
</article>
<?php endforeach; ?>
</div>
<?php wp_reset_postdata(); // IMPORTANT - reset the $post object so the rest of the page works correctly ?>
<?php endif; ?>
If I change ids to $posts in the foreach it show me 1 result but without thumbnail and extra-fields.
