Problem with Updating Values

For some reason I cannot get a value changed in a database with a script. I am designing an MMORPG using PHP for use in the browser, and I need to make a server-status script.

But for some reason I cannot get the value to update, here is the code (excluding database username, password, etc).

PHP Code:

---

 //The MySQL Variables
 $server = "---";
 $username = "---";
 $password = "---";
 $database = "tfdo_e";
 $username1 = $_SESSION['UserName'];
 $password1 = $_SESSION['PassWord'];
 
 mysql_connect($server,$username,$password);
 @mysql_select_db($database) or die("Unable to select database");
 
 //Send Query To Set Players + 1        
         $query="SELECT Kingdom FROM tfdo_e_users WHERE Username=$username1 AND Password=$password1";
         $kingdom=mysql_query($query);
         
         if ($kingdom == "FOD")
         {
            $playerkingdom = "Forest of Draagul";
        }
        if ($kingdom == "VOS")
        {
            $playerkingdom = "Valley of Snakes";
        }
        if ($kingdom == "CON")
        {
            $playerkingdom = "City of Nahana";
        }
        
        $query="SELECT Server FROM tfdo_e_server WHERE Server=$playerkingdom";
        $number=mysql_query($query);
        $finalnumber=$number+1;
        
        $query="UPDATE tfdo_e_server SET Players='$finalnumber' WHERE Server='$playerkingdom'";
        mysql_query($query);
}
else
{
js_redirect_notloggedin();
}

function js_redirect_notloggedin($url="notloggedin.php", $seconds=0.1) { 
    echo "<script language=\"JavaScript\">\n"; 
    echo "<!-- hide from old browser\n\n"; 
     
    echo "function redirect() {\n"; 
    echo "window.location = \"" . $url . "\";\n"; 
    echo "}\n\n"; 

    echo "timer = setTimeout('redirect()', '" . ($seconds*100) . "');\n\n"; 

    echo "-->\n"; 
    echo "</script>\n";

    return true;
}

What are the echoed values of $finalnumber and $playerkingdom just before you update?

What do you mean "What are the echoed values?", there are no echoed values, this is PHP 5 meaning that I can just store variables at runtime, if that is what you are asking.

hmm, couldn't you -always- store variables at runtime?

just before I go into anything, why don't you use elseif() statements instead of 3 seperate IF statements when defining $playerkingdom? Just curious, and thought it might help a bit.. although it has nothing to do with your problem!

Looking at your code and thinking back to past experiences, the only problem I can see is that you're using $query twice and one is used in a query to define a variable. You could always try changing the second variable's name to see if the problem persists, and I just bring this up because from what I've experienced if you define a query to a variable, the query variable becomes 'reserved,' or something. It was a while ago, but from then on I just have individual names for each query. Honestly, it sounds like a dumb reason for it to not work, but it happens, I suppose. Or, it could have nothing to do with that.

I looked over your stuff a few times and without an error message it seems your SQL statements are fine as are most other things.. so hey, try it out. You could always make a $query[] variable and then do something like:

PHP Code:

---

$query['kingdom'] = "select blahblah from blahblah where kingdom=blahblah";
$blahblah = mysql_query($query);

$query['update'] = "update blahblah set blahblah=blahblah where blahblah=blahblah";
mysql_query($query['update']);

Let me know.

Thanks, I will try that when I get a chance, see, all the code that I am writing is pretty much from memory, so I am seseptible to mistakes like that :).
