I'm looking to make a Geolocation script to find cities in a radius of X Km from a central point.
What do you mean?
For example, in a combobox I choose a city - Rio Claro / SP - hence from that city I want to select some cities within a radius of 50Km, 100Km and so on.
This choice of KM would also be a combobox for the user's choice.
I do not have any script why I never did this. I actually need instructional links and a foundation to start understanding.
The main city to be chosen would come from the database, which will populate a combobox. And the other cities would also be in the database.
