Logoff Without Emptying Cart

I'm working on a modification where it would be advantageous to be able to log the user off without emptying their cart. I'm afraid I don't understand the dynamics at work too well, so I have a question.

I've found that I can do this by nullifying their customer_id. Is this Kosher? Or will Bad Things Happen?

Thanks for the help,
Joe

Re: Logoff Without Emptying Cart

Joe-

If the user is logged in to start with, their cart is saved. If the customer is a guest then the cart is not saved when the session expires.

Please do not PM for support issues: a private solution doesn't benefit the community.

Be careful with unsolicited advice via email or PM - Make sure the person you are talking to is a reliable source.

To clarify ...

the logged-in user has the customer_id set. When the session expires, it is blanked.
the non-logged-in user never has it set.
sessions expire after 24 minutes of inactivity
whilst shopping, the cart is saved/updated every time they click to make adjustments
if you blank the customer_id, you effectively log the customer out.
Or you could just kill the session by calling zen_session_destroy(); (this is the most efficient way)

Re: Logoff Without Emptying Cart

Kim and DrByte,

Thank you for the responses. It sounds like I'm not going to corrupt the system by blanking the customer ID.

Kim, I should have provided a little more info. (; I'm trying to further the appearance that there is no account creation going on for my checkout without account mod. In this case, if a user has begun checking out without an account and then tries to enter a GV--through gv_redeem, the option to enter it during checkout is removed--then I want to give them an opportunity to create an account without having to execute a more conventional logoff and lose their cart contents.

Nulling the customer ID and redirecting them to login, with message, seems to be doing the trick.

Again, thank you both for your help.
