Hello friends, I have 2 vf pages; 1 of registration and the other of my "shop".
I dont know how to save the customer id that logged in the registration page.

How can I save the session id ? 

Hello, I am new here and I am having some difficulties.
I need to build shop that sells items to the end customers.
My data model is :
1. custom objects: Customers, fields: user name, phone and email.
2. Items, fields:name, count, price and image.
3. Reservation, fields : master-detail to items, master-detail to customers and a date.

As it now, I am able to make a reservation just for 1 item to 1 customer. I need to to make it that customer will be able to buy more than 1 item.
What changes I need to do for that ?

Thank You!
