Hello, It would be possible with some freelance coding. If you are interested in, please contact me at dominik.capkovic@gmail.com. Thanks!
There is solution for yith-woocommerce-compare.2.0.0 and woocommerce.2.3.13 (wordpress 4.3.1)
In class.yith-woocompare-helper.php at public static function standard_fields add
'character' => __( 'Characters', 'yith-wcmp' ),
In class.yith-woocompare-frontend.php at public function get_products_list add
case 'character':
$chars = get_post_meta($product_id, 'characteristics' );
$product->fields[$field] = $chars[0];
break;
after
case 'description':
$product->fields[$field] = apply_filters( 'woocommerce_short_description', $product->post->post_excerpt );
break;
where characteristics is My Custom Field.
This don’t work on older version of yith-woocommerce-compare
This don’t work on woocommerce2.4.x
