Customizing affiliate program

Hello
I have a question. What are the ways I can customize the affiliate program so that all sales were as affiliate sales? And the partner ID number was the ID of the same buyer.
Can this be done not appending a URL ?partner_id=XX ?
(It is preferred to modify the code once)

How to activate the affiliates by default, I found here:

Thanks in advance.

Hi,

Yes, you will first need to have the affiliates activated by default.
Then, you will need to edit the file plugins/system/hikashopaffiliate.php and change the line:

$partner_id = hikashop_decode(JRequest::getCmd('hikashop_affiliate',0,'cookie'),'partner');

to:
$partner_id = $order->order_user_id;

Thank you for such a quick response.
I'll try it.
