I've been using this contribution for years and it works great. Thank you for the great mod. Unfortunately, I'm so rusty with coding now that I can't seem to figure out how to make it do what I need. I'm running 2.3.
I would like to modify the referral code a little to add the customer's referral source information to the admin/customers.php detail page. (the admin page where you see editable customer name, address, ph#, etc.). I need to display it, but also make the data editable, like the customer's phone and fax number, etc.
Can someone suggest the mods needed to admin/customers.php to add this functionality.
I'm lost.
