Using a Highscore Tutorial

Hi guys,

I'm using Glen Rhode's highscore tutorial that provides the necessary files to create a highscore system. You can see the tutorial here.

I have uploaded the scores.php file as it said to, and creating a new directory from here called scores with permission set to 777. It then asked to run a link provided which should display a highscore setup.

However, when I put the link in my URL I get the following: click!


The PHP code provided in scores.php is the following, although, the tutorial never makes mention of having to tinker with this:

PHP Code:

---

<?php
    $winscore = (int)$winscore;

    // Create a Blank File if it doesn't already exist
    if (!file_exists($filename))
    {
        $file=fopen($filename, "w");
        fclose ($file);
    }

    // Read the file in
    $oscores = file ($filename);
    $numreadin = count($oscores);

    // Break out the data into a new 2-d array called $tscores
    for ($i = 0; $i < $numreadin; $i++)
    {
        $g = unserialize($oscores[$i]);
        $tscores[$i][0] = $g[0];
        $tscores[$i][1] = $g[1];
    }

    // Fill in any missing data with none/0
    for ($i = $numreadin; $i < $scoresize; $i++)
    {
        $tscores[$i][0] = 0;
        $tscores[$i][1] = "none";
    }

    // Process the actions    

    // Insert a score/name
    if ($action == "INSERT")
    {

        // Add name to end of list, and sort
        $tscores[$scoresize + 1][0] = $winscore;
        $tscores[$scoresize + 1][1] = $winname;
        rsort ($tscores);

        $file=fopen($filename, "w");

        // Write them out
        for ($i = 0; $i < $scoresize; $i++)
        {
            $st = serialize($tscores[$i]) . "\n";
            fputs($file, $st);
        }

        fclose($file);
    }

    // Clear the list    
    if ($action == "CLEAR")
    {

        $k[0] = 0;
        $k[1] = "none";
        $ser = serialize($k);

        $file=fopen($filename, "w");

        for ($i = 0; $i < $scoresize; $i++)
        {
            $st = $ser . "\n";
            fputs($file, $st);
        }

        fclose($file);
    }

    // Process the OUTPUT options
    if ($viewtype == "HTML")
    {
      // HTML PAGE CREATED HERE
      ?>


        <table cellpadding=2 cellspacing=2 border=0 width="152">
        <tr align=center> 
        <th bgcolor="#000033"><font color="#FFFFFF" face="Arial, Helvetica, sans-serif">#</font></th>

        <th bgcolor="#000033"><font color="#FFFFFF" face="Arial, Helvetica, sans-serif">Score</font></th>
        </tr>

         <?
    
        for ($i = 0; $i < $scoresize; $i++)
        {
            echo ("<tr bgcolor='#666666' align='center'><td><font size='2' face='Arial, Helvetica, sans-serif'>");
            echo ($i + 1);
            echo ("</font></td><td><font size='2' face='Arial, Helvetica, sans-serif'>");
            echo ($tscores[$i][1]);
            echo ("</font></td><td><font size='2' face='Arial, Helvetica, sans-serif'>");
            echo ($tscores[$i][0]);
            echo ("</font></td></tr>");
        }

        ?>
        </table>
      <?

    }

    // FLASH DATA CREATED HERE
    if ($viewtype == "FLASH")
    {
        for ($i = 0; $i < $scoresize; $i++)
        {
            echo ("NAME" . $i . "=");
            echo ($tscores[$i][1]);
            echo ("&SCORE" . $i . "=");
            echo ($tscores[$i][0]);
            echo ("&");
        }
    }

?>

I know every little of PHP and was hoping for a quick way of implementing a simple highscore system into my quick puzzle game. Can anyone help me out?

Thanks! :)

Hi,

this is very old code. Some time in 2002 php was changed so that variables sent from the web do not automatically become php variables but need to be called explicitly

You would at least need these lines

Code:

---

<?php
$winscore = $_REQUEST['winscore'];
$filename = $_REQUEST['filename'];
$action = $_REQUEST['action'];

---

to make the old tutorial work.
However, I would not like to use this one...
First question: do you need the ability to maintain more than one highscore list (e.g. for a site that has various games, and each one has its independent scores)?
If not, just use an explicit filename .... this prevents idiots from attempting to create crap files all over the place

Well, I hope to make a few simple puzzle games to just hold me over while I'm waiting around on my main project. So I believe I'll be needing to maintain multiple highscores independent from the others.

I'll try working with the code you gave me, but any different directions that you can suggest are appreciated. :)
