First of all if you send request by POST ($.post) then in PHP you var
will be in $_POST array, if by GET ($.get) in $_GET (there is an
exception, read about "register_globals"),
so in PHP you should use $_POST['namn']
Second of all, your request imho runs well (you can check that with
Firebug (in NET tab)), but you forgot to put callback:
$.post("test.php",{
namn: $("#namn").val()}, function(data) { //this is callback
alert(data); //do something with return data
});
and thats all! :)
Hope it helps :)
