In this course, author Lawrence Cramer offers two approaches to implementing ecommerce functionality in Dreamweaver: introducing basic ecommerce functions to an existing site and creating a stand-alone ecommerce solution with PHP and MySQL. The course explores choosing a payment vendor, creating a simple buy button, configuring a store with the Cartweaver extension, adding products and discounts, and managing inventory. The course also provides guidance on securing an ecommerce site, preparing for the site's launch, and effectively promoting a store. Exercise files accompany the course.
