JSON/ php wont carry over data =(

I'm playing around with JQM and JSON for the first time. Iv watched a few videos online and everything seems really simply however no matter what I try I cant get it to carry over my form data. please help =(

JS

        var myURL = "http://www";
        contents = $('#form').serialize();

        $.ajax({
            url: myURL,
            dataType: 'json',
            type: 'post',
            data: contents,
            contentType: "application/json; charset=utf-8",
            async: true,
            beforeSend: function() {
                // This callback function will trigger before data is sent
                $.mobile.showPageLoadingMsg(true); // This will show ajax spinner
            },
            complete: function() {
                // This callback function will trigger on data sent/received complete
                $.mobile.hidePageLoadingMsg(); // This will hide ajax spinner
            },

            success: function(data) {
                console.log(data);


            },
            error: function (request,error) {
                // This callback function will trigger on unsuccessful action
                alert('Network error has occurred please try again!');
            }
        });


     } else {
        alert('Please fill all nececery fields');
    }
    return false; // cancel original event to prevent form submitting
  });
  });

PHP

<?php

header('Content-type: application/json');

$json = array(
'success'       => false,
'result'        => 0

);

if(isset($_POST['name'], $_POST['email'], $_POST['memory'])){

$name       = $_POST['name'];
$email      = $_POST['email'];
$memory     = $_POST['memory'];

$json['success'] = true;
$json['result']  = $name;

}

echo json_encode($json);


?>

How do you know that the form variables are not being sent to the server? It looks like it should work, so if you are not getting a javascript error, and the server is not returning an error, then I would suspect that 

if(isset($_POST['name'], $_POST['email'], $_POST['memory']))

is evaluating to false, which may mean the form names are different.

Normally when debugging AJAX I will dump the variables to a text file. Try a 

file_put_contents("postData.txt", var_dump($_POST));

Then you can see if the variables are set. This is where I would start.
