Hi Jeroen, I was trying your code but this line of code is giving me NULL's.

$shipping_fields = WC()->checkout()->checkout_fields['shipping'];

I was trying with this but still not having the array, any ideas?

$newObj = new WC_Checkout();
$shipping_fields = $newObj->get_checkout_fields($fieldset = 'shipping');

Thanks!
