I was looking to use the following page to reverse geocode locations which i can then store the data in an online database.

Everythings works on the page as it should, but i want to then store the data in an online database which can then be extracted and displayed.
Im just not sure which details are the ones that i will need to store, and if i can use a map iframe while echoing the details which will show the user the stored location

Any help would be great
