Hey guys!
Thanks for taking a look.
Have looked around but can’t find an answer…

Here is my code:

function relation_product() {
	global $post;	
	$product = wc_get_product( $post->ID );// Check for the custom field value
	$title = $product->get_meta( 'prenomnom_auteur1' );// on récupère l'ID du post Auteur
	
	if( $title ) {// Only display our field if we've got a value for the field title
		$post_1 = get_post($title);
		
		$values = get_post_meta( $title, 'du_meme_auteur', true);
		if($values){
			echo '<ul>
foreach($values as $agrege)
			{
				
				setup_postdata($agrege); 
				wc_get_template_part( 'content', 'product' );  
			}
			echo '</ul>';
			wp_reset_postdata();

		}
		// always good to see exactly what you are working with
	var_dump($values);
	}
	
}
add_action( 'woocommerce_after_single_product_summary', 'relation_product' );

The var_dump result is : array(3) { [0]=> string(4) “1208” [1]=> string(4) “1114” [2]=> string(4) “1102” }

Thanks a lot for help!

This is because you are using get_post_meta() instead of get_field() https://www.advancedcustomfields.com/resources/get_field/

ACF only stores the post IDs of the posts in a relationship field. These IDs are stored as strings. When you use get_post_meta() you can only get what ACF stores. If you want ACF to do the work of getting the post objects then you need to use the ACF functions.

Thanks a lot!

I replace :
$values = get_post_meta( $title, 'du_meme_auteur', true);
by
$values = get_field('du_meme_auteur', $title, true);

and now my array is returning post object.

Thanks again!

There is still a tricky issue to display it with :

foreach($values as $agrege)
			{

				setup_postdata( $GLOBALS[$agrege]); 
				wc_get_template_part( 'content', 'product' );  
			}
			echo '</ul></div></div></div>';
			wp_reset_postdata();

but I avoid the problem with displaying it a different way. `
