Re: Object disappearing across pages

Yes, I'm defining the class then starting the session. Should teh session be started in the class definition also? I've tried it with and without and it doesn't seem to make much difference. Something is definitely wrong with how these variables are getting defined and manipulated. I looked at the session file and saw this: !sess_login|sess_cart|O:4:"cart":2:{s:7:"cart_id";s:32:"35634fcab6ae6f1730db1942065b563f";s:5:"items";s:0:"";} (sess_login is another variable I anticipate using, but I'm not using it yet). So the variable names are there, and the cart_id has been set, but the add method I'm using doesn't seem to put anything in $this->items. I've read something about defining all session variables as global within the functions that call them; does this need to be done?
