cakephp auth session regeneration

Question

1. We are using Cakephp framework version 2.0.6
2. The site is "supposed" to allow an anonymous user to "add to cart."
3. We are using the session id (using cake's native session class) to store the anonymous user's information in a db table.
4. When the user goes to checkout, then we want to ask "are you a current member? If so, click yes to login or no to create an account."

ISSUE:

Regardless of what they choose, the user either then has to login, or create a new user/pass (and then login) which is causing cakephp to regenerate a session ID. This is making it impossible in the new session to grab what that user added to the cart when they were anonymous just 5 minutes prior. In other words, the anonymous user's session id changes between when they are anonymous and after they login/create-user, making it impossible to identify their cart post-login.

Is there a way to prevent cakephp from regenerating a session in this scenario, or a better way to accomplish what we are trying to do while still keeping our order flow (ie: anonymous being allow to add to cart, before login/create)?

Answer 1

It is this reason that shopping carts are more often than not stored in Cookies. That way you can easily retrieve the saved information post-authentication.

If you insist on using Sessions to store this data, consider setting your Security.level setting to 'low'. That should prevent CakePHP from regenerating the session ID.
