Filter join request and then pass on to CBSubs

We have a problem with members re-joining (joining anew) instead of renewing subscriptions. Right now, we have a menu item that is CB REgistration Form.

My thought is to put our own module in front of it to attempt to determine whether the person is already registered. That is pretty straight-foward, although not bullet-proof.

Is there any way within CBSubs (i.e., without customization) to pass the info on to CBSubs to complete the registration wihout having to enter all of the information again?

TIA.

You could put the login form directly on the registration page. This can be enabled within CB > Configuration > Registration.

Do you mean complete the invoice address fields? CBSubs payment happens after the user has registered and not before so confused on what you're asking, sorry.

Thanks for the reply. Sorry I wasn't sufficiently specific.

What I'm trying to do is intercept new registrations to see if the person is already registered (likely with an expired subscription). If not, do the normal registration. If already registered, direct them to renew or upgrade their subscription.

My thought was to have my own code as a module for new user registration. The code would check the database and either pass the user on to CB or tell them how to renew/upgrade their subscription.

In order to do this, I have to have a "New User" form to collect name and email address. If the user is not already in the database, I want to pass this on to DB for new user registration without having the user enter the data again. The question is whether there's a way to do this without customizaion.

There's no functionality for this. They just need to stop trying to make a new account anytime they renew. Sorry, I just don't understand the thought process behind doing that. Is this common enough to be a problem? Registering with existing username or email will reject it with an error.

There's no way to do that without coding all of that.
