I needed to attach the extra field to several PIDs so here’s a dirty fix:

Open conditional-woo-checkout.php and add the following:

foreach ( $woocommerce->cart->get_cart() as $cart_item_key => $values ) {

$items = array(1186,1511,1512,1513,1514);			

 if(in_array($values['product_id'],$items)){	

	 /*  $_product = $values['data'];

        if ( $_product->id == $product_id ) { */
            $check_in_cart = true;
        }
    }
    return $check_in_cart;

replace the PIDs in an array with your own.
