Passing javascript variable to PHP

Hi

I wonder if it's possible to pass a variable from a jQuery script to a PHP-page and put the variable into a session variable like this:

$_SESSION['mapZoomArea'] = (isset($_GET['mapza']) ? $_GET['mapza'] : "";

I'm not sure how to pass the variable and the url to the server? Preciate some help!

Thanks!

If you want a dedicated service specifically for writing this value into the session, you probably should make it a POST request (GET will work too, but GET requests should be for data retrieval, not for writing to the server).

Therefore, simply create a new PHP page, let's say "storezoomarea.php", and have jQuery make an Ajax POST request to that page:

$.ajax({url: "storezoomarea.php", type: "post", data: {"mapza": mapza}})

Then, on the server side, you can retrieve it from the _POST variable:

$_SESSION['mapZoomArea'] = (isset($_POST['mapza']) ? $_POST['mapza'] : "";
