How to add star-rating for product items in the wishlist.php template?

  • I would like to add star ratings for the product to the wishlist.php template.

    I tried using this (copied from woocommerce)

    <?php echo '<div class="star-rating"><span style="width:'.( ( $average / 5 ) * 100 ) . '%"><strong itemprop="ratingValue" class="rating">'.$average.'</strong> '.__( 'out of 5', 'woocommerce' ).'</span></div>'; ?>

    but I dont know how the $average variable is calculated? It just shows empty stars when generated in the browseer.

    I’m not a programmer. Any ideas? Thanks
