  Hello and my compliments for your amazing job!

  I have a problem.
  I have two custom post type: ‘books’ and ‘authors’.
  For the ‘books’ posts I had create a custom field Post Object with the ‘authors’. For each book I can choose one or more authors.
  In the single book loop, the function get_field(‘authors_of_the_book’) returns a list of Object that contain all the information about the author post type.

  How I can filter, in the single author page, the books for this author?

  and by this resource

  $autore = get_the_ID();
  			
  $args = array(
  	'post_type' => 'libri',
  	'post_status' => 'publish',
  	'order'	=> 'DESC',
  	'orderby' => 'date',
  	'ignore_sticky_posts' => true,
  	'posts_per_page' => -1,
  	'meta_query' => array(
  		array(
  			'key' => 'autori',
  			'value' => '"' . $autore . '"',
  			'compare' => 'LIKE'
  		))
  	);
  
  $libri = new WP_Query( $args );
