title: Wordpress Advanced Custom Fields display two fields from two different post types in one template
body: <p>I have two post types. I need to display content from each within the same loop. At the moment, I can call the 'releases' post type to display content, but I also need to call the 'artists' post type to display some content in the same DIV.</p>
  
  <p>The below line breaks the page with a ‘Catchable fatal error: Object of class WP_Post could not be converted to string error’.</p>
  
  <pre><code>&lt;?php the_field('release_artist_name'); ?&gt;
  </code></pre>
  
  <p>How do I get the release_artist_name field to stop breaking the site? It is a field via a Post Object (post type is named ‘artists’). Any help appreciated.</p>
  
  <pre><code>    &lt;?php 
         $posts = get_posts(array(
          'post_type'     =&gt; 'releases'
      )
         ));
  
         if( $posts ): ?&gt;
      &lt;?php foreach( $posts as $post ): 
         setup_postdata( $post )       
         ?&gt;
  &lt;div&gt;
      &lt;?php the_title(); ?&gt; // THIS COMES FROM RELEASES POST TYPE
      &lt;?php the_field('release_artist_name'); ?&gt; // THIS SHOULD COME FROM ARTISTS POST TYPE BUT BREAKS THE PAGE
  &lt;/div&gt;
  
      &lt;?php endif; ?&gt;
      &lt;?php endforeach; ?&gt;
      &lt;?php wp_reset_postdata(); ?&gt;
      &lt;?php endif; ?&gt;
  </code></pre>
  
  <p>As asked for below, results from the print_r($posts)...</p>
