Witam.
Mam problem z aktualizowaniem wpisów do bazy danych za pośrednictwem skryptu PHP na serwerze.
kody PHP (Hasło i login podaje bo na tej bazie i tak nic nie ma specjalnego):

?>
<?php
class DB_CONNECT {
function __construct() {
$this->connect();
}
function __destruct() {
$this->close();
}
function connect() {
require_once __DIR__ . '/db_config.php';
$con = mysql_connect(DB_SERVER, DB_USER, DB_PASSWORD) or die(mysql_error());
$db = mysql_select_db(DB_DATABASE) or die(mysql_error()) or die(mysql_error());
return $con;
}
function close() {
mysql_close();
}
}
?>
<?php
$response = array();
if (isset($_POST['id']) && isset($_POST['user']) && isset($_POST['pass']) && isset($_POST['table'])) {
$id = $_POST['id'];
$user = $_POST['user'];
$pass = $_POST['pass'];
$table = $_POST['table'];
require_once __DIR__ . '/db_connect.php';
$db = new DB_CONNECT();
$result = mysql_query("UPDATE '$table' SET user = '$user', pass = '$pass' WHERE id = '$id");
if ($result) {
$response["success"] = 1;
$response["message"] = "User successfully updated.";
echo json_encode($response);
} else {
}
} else {
// required field is missing
$response["success"] = 0;
$response["message"] = "Required field(s) is missing";
// echoing JSON response
echo json_encode($response);
}

Czyli nie ma odpowiedźi na mojego POSTa bo nawet jak ręcznie wejde na ten adres http://stasbar.esy.es/update_product.php to dostaje odpowiedź. Macie jakieś pomysły ?
Dodam że gdy wysyłam zapytanie bez parametrów to dostaje zwrotne D/reader.readLine()﹕ {"success":0,"message":"Required field(s) is missing"}
