An independent freight company needed a form for customers to request shipping rates but needed to insure the customers entered valid addresses. Down Home Consulting developed a interactive form using AJAX and PHP to ensure the customer selected a valid City, State and Zip Code combination.
Using the new AJAX technology, the form senses when the customer enters a city, state and/or zip code then behind the scenes contacts the database, validates the information and if needed returns a drop down for the customer to select a valid city, state or zip code.
The biggest benefit for the customer is this is all done on one page where other similar web sites often use several web pages or use one web pages that stops and refreshes the page when some information is change.
