Phonegap ajax / php发布不起作用

Question

I have been trying to POST data from input to PHP (which will write to the .json file) But I only end up getting 404 XHR errors in browser. (SEE LATEST EDIT)

Note: am using the Phonegap Desktop version instead the CLI

So far I have added all the security, access, allow-navigation into the config.xml.

EDIT: Updated the code below and after made the path to php file absolute and now I get a new error: "Access-Control-Allow-Origin missing)

AJAX

$.ajax({
                crossDomain: true,
                type: "POST",
                contentType: "application/json; charset=utf-8",
                url: "http://192.168.170.2/php/wjson.php",
                dataType: "json",
                data: "titel=" + titel + "&notitie=" + notitie + "&datum=" + vandaag,
                success: function (data) {
                    console.log(data);
                },
                error: onError

            });

PHP

    <?php
  header("Access-Control-Allow-Origin: *");  
  header("content-type: application/json");
  header("Access-Control-Allow-Methods: PUT, POST");
  header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept");

  if(!$_POST) exit;

  $titel = $_POST['titel'];
  $notitie = $_POST['notitie'];
  $datum = $_POST['datum'];

  $file = 'data/notities.json';

    $json = json_decode(file_get_contents($file),TRUE);

  $json[count($json)] = array("titel" => $titel, "notitie" => $notitie, "datum" => $datum);

  file_put_contents($file, json_encode($json,TRUE));

?>

What if you add the Access-Control-Allow-Origin to your .htaccess file?

Header set Access-Control-Allow-Origin "*"
