This is the code i put in my child’s theme functions.php (at the beginning of the file)
function woo_related_products_attr() {
global $product;
$args = array(
'post_type' => 'product',
'no_found_rows' => 1,
'posts_per_page' => 8,
'ignore_sticky_posts' => 1,
'orderby' => $orderby,
'post__in' => $related,
'post__not_in' => array($product->id),
'woocommerce_attributes' => 'colour',// please replace with color,size etc
);
return $args;
}
add_filter( 'woocommerce_related_products_args', 'woo_related_products_attr' );
