You can use GDownloadUrl() to communicate with your server in either direction, i.e. for uploading as well as downloading.
For example in this example: http://econym.org.uk/gmap/example_store.htm I use the following code: var lat = lastmarker.getPoint().lat(); var lng = lastmarker.getPoint().lng(); var url = "myserver.php?lat=" +lat+ "&lng=" +lng +"&details="+details; GDownloadUrl(url, function(doc) { }); That sends a message to myserver.php that looks like http://econym.org.uk/gmap/myserver.php?lat=12&lng=123&details=foo In that example, myserver.php appends the data to a flat file, like this <?php $lat = $_REQUEST["lat"]; $lng = $_REQUEST["lng"]; $details = $_REQUEST["details"]; $file = fopen("details.txt","a"); $output = $lat . "|" . $lng . "|" . $details . "\n"; fwrite($file, $output); ?> but if I had SQL on my server the server could write to an SQL file. Hint: It's generally easier to get your system working if you write lots of small simple server scripts that do one thing each, rather than try to write one complex server script that can perform lots of different functions. -- Mike Williams
