After learning WordPress theme development and rebuilding thriftynick.com (this site) as a custom theme, the next logical step was to learn WordPress plugin development. Introducing “TN Map Zones,” my first WordPress plugin! The idea for this plugin came from a client on a freelancing site who needed the functionality for his site. It’s also a better solution to what I currently have on my pizza delivery app for determining deliverable addresses. Rather than simply using zip codes, you can set a polygon area on the map. When the customer enters their address, it checks to see if it is contained inside any of the polygon areas. Please watch the video for a full demonstration.
