What am I doing wrong? Sending variables to PHP

[ki]

Mind you, I've altered and butchered my code several times trying to find why it's not sending anything even though it says it does.

 

geo.html

navigator.geolocation.getCurrentPosition(GetLocation);
function GetLocation(location) {
var usr_lat = location.coords.latitude;
var usr_long = location.coords.longitude;
$.ajax({
url: 'local_settings.php',
type: 'POST',
data: { user_lat : usr_lat, user_long : usr_long },
success: function(data)
                    {
                       alert("success! user_lat:" + data);
                    }
});
}

local_settings.php

if (isset($_POST['user_lat']) && isset($_POST['user_long'])) {
$_SESSION['user_lat'] = $_POST['user_lat'];
$_SESSION['user_long'] = $_POST['user_long'];
}

How do you know it's not sending anything? Your local_settings.php script doesn't return anything back to the ajax, so data does not contain anything in your success() method. It just sets Session vars on the server.

Cronix is right.  You should use firebug to determine if the ajax call is happening.  In your code snippet, I don't see you doing a session_start() at the top either.

I don't need anything returned, just sent to the server.

There is a session_start(), I didn't include it in the code I posted.
