Zapisywanie zmian w SlickGrid za pomocą php

Ok, więc znalazłem problem, na wypadek, gdyby ktoś walczył, aby to wszystko działało, oto działający kod, pobiera dane z bazy danych, a następnie wysyła zmienione dane na inną stronę w celu przetworzenia, wymaga trochę udoskonaleń , stanie się to, gdy już to wszystko zaimplementuję:
<?php 
include("includes/check_session.php");
require_once('includes/functions.php');
require_once('includes/config.php');

$data = '';
$i = 0;

$query = "
    SELECT * FROM `prices`";
$result = mysql_query($query);
while($row = mysql_fetch_array($result, MYSQL_ASSOC)){
    $data .= '
        data['.$i.'] = {
            id: "'.$row['id'].'",
            title: "'.$row['title'].'",
            duration: "'.$row['duration'].'",
            percentComplete: "'.$row['percentComplete'].'",
            start: "'.$row['start'].'",
            finish: "'.$row['finish'].'",
            effortDriven: "'.$row['effortDriven'].'"
        };
    ';

    $i++;

echo $data;
}

?>
