[Google Maps API v2] Re: passing a geolocated lat,lng to a function that uses a php file

Hi.

If i understand your question then i think you could create a hidden
form field.

Once you have the location (from map 'a') populate the hidden form
field with the formatted lat and lng:

// myLatLng assumed to be a LatLng object that's already defined in
your code

document.forms.myForm.latlng.value=myLatLng.toUrlValue();

A simple form:

<form id="myForm">
<input type="hidden" name="latlng" />
</form>

That'll leave your createxml.php script to parse the POST or GET
latlng value which will be a comma separated string: 'lat,lng'.
