I need to develop a small Drupal 7 module that exposes a views 3 filter for the Geolocation Field module.
The Geolocation Field module ([url removed, login to view]) uses Field API to store latitude and longitude information associated to a node.
What I need is to filter nodes based on proximity with respect to a given location.
The module to be developed (geolocation_proximity) needs to provide a views 3 exposed filter that do at least the following:
- let the user choose his/her location with the geolocation map widget
- let the user enter a maximum distance from his/her location
- filter views result based on proximity value
optionally would be great to provide an html5 implementation to initialize the user's location based on his/her current location
please let me know if you need some clarifications
