Question

I just need to know how to go about getting a postcode from the longitude and latitude.

Im using the google maps api to get the long and lat based on a search such as ‘manchester’ i then need a to get the postcode from this to query my database.

My code so far is

function getLatLng()
{
    var localSearch = new google.maps.Geocoder();
    var postcode = $("#address").val();
    localSearch.geocode({ 'address': postcode },
                    function(results, status) {
                        if (results.length == 1) {
                            var result = results[0];
                            var location = result.geometry.location;
                        }
                        else 
                        {
                            $("#error").html("Address not found");
                        }
                    });
}

What you’re trying to do is (an example of) ‘Reverse Geocoding’

See:
