Group subscription plan with variable price

I need to vary the price of a subscription plan during registration, the length of the plan remains fixed for 1 year.

The plan is for a group membership, and there's a fixed price per member, on the registration form I want them to enter the number of members, and multiply this by the price, the result becomes the price of the subscription.

Please tell me the best way to accomplish this.

CB Subs 3.0.0

Only way to do this is to apply negative promotions using CBSubs Promotions. For example you can have 10 CBSubs Promotions that check if the field is equal to a certain value and have that increase the price. For example if the member field equals 1 apply a -20 promotion, which will increase the price by $20. If you want this to support an unlimited number of members you'll need to use a CB Query Field to calculate the cost per person then supply that to a CBSubs promotion as the value. Few of this exact usages have been posted already, please search for further details.

Thanks, I did see the other posts regarding this but I thought It was worth asking in case there was another way.

I've just installed the CB Query field plugin to try and calculate the price to display it for the person registering, I have a field called cb_members which the user types in, and a field called cb_price which is the CB Query field.

Please give me some idea of how to add this query, or a link to some documentation, or examples.

The below query for example should multiply the member count by a static value.


This makes each member cost $20. Adjust the number as needed. You then should be able to substitute it in as the promotion amount using the below.

-[cb_queryfield]

Please understand this is all just an example. It is not tested and you will need to adjust field names as needed.

Thanks, I tried this but I can't make the CB query field display on the registration form, it's published and Show at Registration? is set to yes.

Is there something else I need to do?

CB Query Field can't display on registration form. It has no edit display. It also can't display in profile edit. You only need it to calculate the cost for your CBSubs Promotions and it's not intended to be displayed.
