probably a simple javascript question

[dale282]

hi,

i'm completely new to javascript but i'm trying to adapt a script that geocodes UK postcodes to latitude/longitude. the tutorial is here, and my working version is here.

all i want to do is pass the lat/long information (that is displayed when the Show Lat/Lng button is clicked) through to php, perhaps via a hidden field on a form. i don't even need to map, just the field for entering a postcode.

an example uk postcode is SW1A 1AA

any thoughts anyone?

thanks in advance...

Hey dale,

I had a quick look atthe stuff you posted. the link to google does not link to a tutorial, but to a generic google/uk geocoding api page.

There probably is a way to get the lat/lot values directly, instead of through a popup, but you woul dhave to check the manual on how to get it, or trwl through the js on your page that generated the alert() which obviously has access to the latlon

Is spotted the js function which alert the latitude and longitude:

function showPointLatLng(point)
{
	alert("Latitude: " + point.lat() + "\nLongitude: " + point.lng());
}

Well you could put those in hidden form values but this should also work:

function showPointLatLng(point)
{
	window.location = "process.php?latitude=" + point.lat() + "&longitude=" + point.lng();
}

In that example it would redirect you to process.php where you can access those variables with get ($GET['latitude'] and $GET['longitude']).
