It doesn't make any difference where your submit button is.
Once you get the server to a state where it updates the database when
you type the URL into the browser address bar, then all you have to do
is to arrange for the client code to generate the same URL, either by
using a form action, or by using GDownloadUrl.
Suppose you want to send something in this format to your server
gmaps.php?Server=foo&lat=23.824&lng=-83.987
There are two steps.
1. You need to capture the latlng info into a global variable. Code
executed from HTML runs in global context, so it can only see global
variables.
var theLatLng;
GEvent.addListener(map, 'click', function(overlay,latlng){
dog = false;
theLatLng = latlng; // copy the location into a global
});
2. Send that data to the server
<input type="button" value="Submit" onclick="send();return false" />
function send() {
if (dog) {
alert("You must select a point before clicking Submit");
} else {
var url = "gmaps.php?Server=foo&lat=" +theLatLng.lat()+
"&lng=" +theLatLng().lng();
GLog.write("About to send "+url+ " to the server");
GDownloadUrl(url,function(){});
}
}
