I'm looking to set up a page on my site that contains a Google Map of a certain country. The idea behind the map is for people to be able to click on the map in order to indicate the exact area/town where they live. I want this info to be then collected in a database so I can then notify them when a certain service is available in the area they live. Has anyone heard of this been done before or able to explain how it would be done. Examples of sites who already have it would be great. Any help much appreciated.
Here is an example of something that uses Google Maps with a database, though this is a guest book. http://www.daftlogic.com/projects-google-maps-guestbook.htm They have also given information on its construction: http://www.daftlogic.com/sandbox-google-maps-guestbook.htm EDIT: Upon reading I notice that they use a .txt file to record clicks, though modifications could allow a database structure.
