Question: I have a PHP script at the moment which allows users to enter a UK postcode.

I was wondering if there was a way I could get their geolocation from the postcode they enter. (Through Google's API or something?)

I have tried <http://code.google.com/apis/maps/documentation/geocoding/index.html> but it requires a full address, whereas I only have a postcode.

Help would be appreciated, thanks :)

Answer: 
Here is a downloadable database for all UK postcodes with latitude and longitude.

Here is Step by Step tutorial for Geocoding UK Postcodes with Google Map API

Though this is already answered:
here is a link for a simple API that allows obtaining GeoJson for googlemaps..query by single or combining UK Postal Code(ex. ZE1 0AE) ,Sector, District, City, and Wards Boundaries
