nel file index.html

cambia

codice:

<form action="upload.php" method="post">

con

codice:

<form action="upload.php" enctype="multipart/form-data" method="post">

cancella il file success.html e crea il file success.php con questo codice

codice:

<html>
<head>
<title>upload</title>
</head>
<body>
Complimenti hai caricato un file!

<?php
$id = $_GET['id'];
include "connessione.php";
$query = mysql_query("SELECT nome_file FROM uploads WHERE id=$id");
$row = mysql_fetch_array($query);
mysql_close();
$md5 = md5($row['nome_file']);
$link = "<a href=\"download.php?id=$id&file=$md5\">download.php?id=$id&file=$md5</a>";
echo "link per il download:
$link";
?>
</form>
</body>
</html>

file upload.php

codice:

<?php

if(isset($_FILES['file'])){

    $target = "uploads/".basename($_FILES['file']['name']);

    if(move_uploaded_file($_FILES['file']['tmp_name'], $target)){

        include "connessione.php";
        mysql_query("INSERT INTO uploads values('','$target')");
        $id = mysql_insert_id();
        mysql_close();
        header("Location: success.php?id=$id");
    }else{
        header("Location: epicfail.html");
    }
}else{
        header("Location: epicfail.html");
}

?>

crea il file download.php

codice:

<?php

$id = $_GET['id'];
$file = $_GET['file'];
include "connessione.php";
$query = mysql_query("SELECT nome_file FROM uploads WHERE id=$id");
$row = mysql_fetch_array($query);
mysql_close();
$real = $row['nome_file'];
$md5 = md5($real);

if($file == $md5){

    header("Pragma: public");
    header("Expires: 0");
    header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
    header("Cache-Control: private", false);
    header("Content-Disposition: attachment; filename=" .$real);
    header("Content-Type: application/force-download");
    header("Content-Type: application/octet-stream");
    header("Content-Type: application/download");
    header("Content-Description: File Transfer");
    header("Content-Length: " . filesize($real));
    readfile($file);
    exit; 
}else{
    echo "Spiacente, nessun file da scaricare a quest'indirizzo.";
}
