[woocommerce][http_referer]

Hi there!

I would like to make a little extra at the woocommerce orders.

At the woocommerce plugin>orders we can view the placed orders.

If we click on an order’s number, we can see the submitted datas, and the order details.

What I want is, where the order number shown and the customers IP address, I would like to see next to the IP is where does the customer comes from.

If I can make this with http_referer, which files do I have to edit, and how?

A company is selling products with affiliates, and they want to know when a costumer placing an order, where do they come from?
From google? Facebook? The affiliates website?

I know that there are affiliate plugins, but none of them are so simple as what we want…

Hope there is somebody who made this before.

Regards,
Tom
