Updating something in a database with a php file - php

Question

Hello iam working on a game on unity3d and i have a login/register system that have a database so i have these level thing i want to save in to the users database, just for testing i have created this php file:
<?PHP
$username = $_POST['username'];
$pass = $_POST['password'];
$con = mysql_connect("host","user","password") or ("Cannot connect!" . mysql_error());
if (!$con)
die('Could not connect: ' . mysql_error());
mysql_select_db("database" , $con) or die ("could not load the database" . mysql_error());
$check = mysql_query("SELECT * FROM users WHERE `username`='".$username."'");
$numrows = mysql_num_rows($check);
if($username == null)
{
die ("You are not allowed to access this site! \n");
}
else
{
if ($numrows == 0)
{
die ("Username does not exist \n");
}
else
{
$pass = md5($pass);
while($row = mysql_fetch_assoc($check))
{
if ($pass == $row['pass'])
{
die("saved-SUCCESS");
$sqlUpdate = "UPDATE users SET level='2' WHERE id='1'";
//$SQL = "UPDATE users SET level = '2' WHERE id = 1";
}
else
die("Password is wrong \n");
}
}
}
?>
it does says "saved-SUCCESS" in unity3d so that means this:
$sqlUpdate = "UPDATE users SET level='2' WHERE id='1'";
should work but it doesent
also i have tryed this:
$SQL = "UPDATE users SET level = '2' WHERE id = 1";
but it doesent work either
here is a picture of the user with id 1:

You are not executing your second query but only printing saved-SUCCES
$sqlUpdate = "UPDATE users SET level='Rune' WHERE id='1'";
mysql_query($sqlUpdate);
die("saved-SUCCESS"); //then exit.
As side note i would advise thta your code is highly vulnerable mo mysql injection, you should use prepared statments either with PDO or mysqli, also mysql_* api are deprecated and soon will be no longer mantained.
