DB_cart Class 1.13

DB_cart Class is a MySQL shopping cart script that can be used with third party product catalogues and membership systems. The MySQL database structure is neutral to existing systems.
DB_cart Class can handle the shopping cart (add, update, and empty) and checkout process (set the shipment address and email the order).
For existing cart users, the shopping cart is still available upon the users next visit and is visible by checkout. The last option is configurable togther with a time period.
Enhancements:
- There are modifications and improvements inside the main class file, several examples, and the table structure has been extended.
- There two additional fields for the shipment values (name2 and address2).
- All messages are available in German, English, and Dutch.
- The standard text inside the email messages is in external files now; this content is parsed inside the improved email method.
