Radius Distance Search Plugin.
A plugin for SOBI2, that allows you to add proximity search easily to your existing search form in SOBI2.

The visitor on your page just has to enter his zip code, select the maximum distance from it in miles or kilometres (adjustable in SOBI2 back-end) and he will get all matching SOBI2 entries, considering the standard SOBI2 search results.

Features:

• Easy to install, using the standard SOBI2 Plugin Interface
• Includes Open Geo Database from the GeoNames database
• Includes 12 months Update Service and Support
• Does not require any source code modifications
• Ajax Autocomplete function
• Own database. No need to connect to an external server
• Three Search methods selectable:
  
  • Search Using Geo Coordinates (longitude and latitude for each entry necessary - see Sobi2Wiki for an easy way to get the coordinates in SOBI2)
  • Search Using Postal Code - National (only postal code for each entry necessary)
  • Search Using Postal Code - International (postal code and country code for each entry necessary)
