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. `
