[SOLVED] Coupon code query field / referring user

I have two related questions regarding Promotions.
I have reviewed the use cases in Chater 8 of the documentation, and they were helpful.

My use case is "Refer a Friend" promotion, where I want to offer a $10 credit to a referring user when a new user signs-up and enters the referring user's Joomla ID on the registration form.

Question 1):  Can a coupon code field (referred to within the Promotion) be dynamically populated at registration time? My thought is to create the unique coupon code by concatenating the new user's Joomla ID with the referring user's Joomla ID.

Question 2):  All of the PUCs are specific to the logged-in user/new user. I need to communicate the generated code to the Referring user, not the Registering/New User.
Suggestions?
Best,

If it's a flat credit amount I wouldn't use coupon codes at all. Use an always applied promotion and set its conditions to check if the referral field has a value. Then have that coupons value come from a field. The below for example would pull its coupon value from a field AND subtract it once used.

Basic > Promotion Calculation
Promotion Type: Applies to all purchases
The promotion is: A: A fixed amount A from a CB field
CB Field containing amount: cb_referrals
Deduct used amount from CB field once payment is completed: Yes, remove amount from CB field after payment is completed
Conditions
First condition: This condition:
Date A, Field A or Value A: Following CB field
CB Field A: cb_referrals
Date B, Field B or Value B: Constant Value or String (CB substitutions can be used)
Value B: 0
Condition 1 (> for Dates): A > B (Value A is larger than Value B )

That should cover the promotion aspect. The cb_referrals field would contain how much of a discount they have. So if it's set to 10 they get a $10 discount. I suggest using a number or integer field for this.

Now you just need to add the $10 to the field. You can do that using CB Auto Actions. You said you have a referrer field? If that contains the user id of the user that referred them then you'd just set the Field action to use that field as its User. Now you can easily add $10 to the user that referred them. Another option is to let CB Invites act as your referral system and when an invite is accepted add $10 to the user who sent the invite.

Thanks for the tips, Kyle.
RE:  
Would you use an AutoAction to credit the Inviter's credit field?

Yes, a Field action in CB Auto Actions should work fine for that. The invites_onInviteAccept trigger is fired when an invite is accepted. It contains the below variables.

var1 is the invite object, var2 is the invite code, and var3 is the user accepting the invite. To get the user id of the user who sent the invite you'd use [var1_user_id]. This can be used in the field action to modify the field value of the user who sent the invite.

Excellent - thanks very much - topic is closed...
