Billing and shipping address id

Hi,

No. These are the user_id attached to each address. And thus, it's normal they are always the same for one order since an order is linked to one user only.
If you want the id of the shipping / billing address, they are in billing_address_id and shipping_address_id, but you also have them in order_shipping_address_id and order_billing_address_id.

It's normal they are different.
In HikaShop a user has two sets of addresses. One set with the type "billing" and one set with the type "shipping".
When the user check the checkbox "use the billing address as shipping address", the system will create a copy of the billing address with the type "shipping".
So you should actually never have a billing address and a shipping address with the same id.
In short, you can't base yourself on the id to know if they are the same or not. You'll have to compare each field of both address to see if they are the same or not.

Well, you can check if the billing address is the same as the old billing address.
But even then, it would be possible the customer just create a new address with the same values.
If you really whant to check if an address is the same than another, I don't see another way than checking each field individually.

Hi,

If you register the billing address you enter will have one id, and its copy as shipping address will have another id. It will be the same ids in the order.
If you come back later on, and login and proceed to a payment without changing your billing/shipping addresses, they will have the same ids too.
However, if you modify an address, then the system will automatically unpublish the original address (so that it can still be attached to the old order you made in the past), and the modified address will have a new id.

If you do a guest checkout, then even if you use a the same addresses each time (you will have to re-enter them each time), the addresses will have different ids each time.
