In this 4th video we will create the Inventory management page in the Admin area. List all inventory and make a form and parser for adding new inventory items. The E – Commerce Web Site we will be assembling is one in which all of the inventory is in a MySQL database and we offer a custom PHP cart for a unique shopping experience. It is a site that handles sales, customers, and inventory.
