I'm looking to have a Google Maps search function similar to the one on the homepage at 1800dentist:
http://www.1800dentist.com
I'm familiar enough with the Google Maps API that I could figure out how to load that data from WordPress' database, but I'm also looking for a way to dynamically load that data from custom fields provided by individual members. What I mean is that a user logs into their account, and they can provide an address, broken down into custom fields, and that data can dynamically be loaded into the Google API.
What would be the best way to go about doing something even remotely like this?
