</form>

Page: won.php:

<?php
include_once 'dbconnect.php';
session_start();

if(!isset($_SESSION['user']))
{
 header("Location: /manopuslapis/index.php");
}
$res=mysql_query("SELECT * FROM users WHERE user_id=".$_SESSION['user']);
$userRow=mysql_fetch_array($res);

$wonorlose = $_GET["wonorlose"];
echo $wonorlose;
mysql_query("UPDATE `users` SET credits=credits+'$wonorlose' WHERE user_id=".$_SESSION['user']); 
?>

Answer 1

You have problem in won.php at this line

$res=mysql_query("SELECT * FROM users WHERE user_id=".$_SESSION['user']);

You have $_SESSION['user'] as string.. This must be integer OR you must add quotes:

$res=mysql_query("SELECT * FROM users WHERE user_id='".$_SESSION['user']."'");

Or define $_SESSION["user"] as integer by adding (int) after = where you define it.

UPDATE

Problem solved with teamviewer. User got blank variable $wonorlose because he make AJAX POST without parameters. I changet AJAX POST into AJAX GET with parameter wonorlose and now its working. Final code have only author.
