I've been practicing making screensavers and sometimes give the link out to a webpage that has one or two on it set up as a download. Not for any reason, (I don't charge, or they're not for advertising or anything). Just to share, and maybe possible feedback.

Is there something I can write in with the link that tells me if, and how many times, one has been downloaded?

I've seen on posts here, when someone puts on a link to a graphic, it will say "this has been downloaded 4 times" (whatever)

I can put a counter/tracker on the page, but this doesn't show if anyone is downloading one of the screensavers.

I'm assuming this would be some sort of javascript code? I occasionally attempt to learn something about JS, but mainly what I've ever used has been copy/pasted from something someone else wrote (and is giving away).

And, since it should show the downloading of the actual screensaver, it might be set up inside each link in some way?

Never passing up a chance to learn something new.

Thanks!

This is pretty simple to accomplish with a little PHP

Fisrt you create two PHP pages, one called track.php and one called index.php.

First we need to create the actual tracking page.

This is the track.php page

PHP Code:

//VARIABLEs

$CHECK_URL = TRUE;
$CHECK_URL_REGEX = "/^(http:|ftp:\/\/).*(\.+).*/i";

$CHECK_REFERER = FALSE;
$REFERER_SUBSTRING = "yoursite.com";

/*--------------
DO NOT EDIT BELOW THIS LINE!
--------------*/


$QS = $_SERVER["QUERY_STRING"];

if($CHECK_URL && !preg_match($CHECK_URL_REGEX, $QS)){
    //this didn't match
    echo "<p>The link does not seem to point to a valid URL.</p>";
    exit;
    }

if($CHECK_REFERER){
    if (!stristr($_SERVER["HTTP_REFERER"], $REFERER_SUBSTRING)){
        echo "<p>The referring site does not match. Please make sure that the link you clicked came from the right site.</p>";
        exit;
        }
    }
    
$LogFilePath = dirname(__FILE__) . "/" . md5($QS) . ".log";

//echo "Log path: " . $LogFilePath;
/*
Log file format
The file contains individual pieces of information per line. The lines are:
0: QS, which is the URL
1: Last hit unix time stamp
2: No. of requests
3: Log creation time
*/
//If the file doesn't exist, create it and write the log.
if(!file_exists($LogFilePath)){
    touch($LogFilePath);
    chmod($LogFilePath, 0666);
    $LogString = $QS . "\n" . time() . "\n1\n" . time();
    $FH = fopen($LogFilePath, "w+");
    fwrite($FH, $LogString);
    fclose($FH);
    }
else{
    $FA = file($LogFilePath);
    $Hits = trim($FA[2]);
    $Hits += 1;
    $FA[2] = $Hits . "\n";
    $FA[1] = time() . "\n";
    $LogString = implode("", $FA);
    $FH = fopen($LogFilePath, "w+");
    fwrite($FH, $LogString);
    fclose($FH);
    }

header("Location: " . $QS); 


Next we create the index.php page.
This pages hould have a 1 x 4 table on it.

the table creation html is

<table cellspacing="0" cellpadding="2" border="0">
<tr>
<td class="tblHeading">Requested URL</td>
<td class="tblHeading">Number of Requests</td>
<td class="tblHeading">Most Recent Hit</td>
<td class="tblHeading">First Recorded Hit</td>
</tr>
</table>
</body></html>

the code included in it would be:

PHP Code:


    $dir = dirname(__FILE__);
    // Change to directory
    chdir($dir);

    // Open directory;
    $handle = @opendir($dir) or die("Directory \"$dir\"not found.");

    // Loop through all directory entries, construct
    // two temporary arrays containing files and sub directories
    while($entry = readdir($handle))
    {
        if($entry != ".." && $entry != "."){
            $PathParts = pathinfo($entry);
            if($PathParts["extension"] == "log"){
                $dir_files[] = $entry;
                }
        }
    }

    // Print all files in the curent directory
    for($i=0; $i<count($dir_files); $i++){
        $FA = file($dir_files[$i]);
        echo "<tr><td class=\"DataTD\"><a href=\"" . $FA[0] . "\">".$FA[0]."</a></td><td class=\"DataTD\">".$FA[2]."</td><td class=\"DataTD\">".date("D dMy\nh:iA", $FA[1])."</td><td class=\"DataTD\">".date("D dMy\nh:iA", $FA[3])."</td></tr>";
    }

    // Close directory
    closedir($handle); 


Next we track the links.
Any link you want tracked (say www.yoursite.com/file1.zip) then your link would need to be:
/trak.php?http://www.yoursite.com/file1.zip

note!!
the /track.php assumes you created this in the same directory as the rest of your links files.


Good luck with it.

Thanks!

It'll be a project for tomorrow.
