PHP - Download Script

To give some background, I'm currently working on a private site that allows members access to large document files via a torrent system.

Now, this is the PHP code I have:
Code: [Select]
$id = $_REQUEST['id'];

if (!$id)
httperr();

$res = mysql_query("SELECT name FROM torrents WHERE id = $id") or sqlerr(__FILE__, __LINE__);
$row = mysql_fetch_assoc($res);

$fn = "$torrent_dir/$id.torrent";
if (!$row || !is_file($fn) || !is_readable($fn))
httperr();

$fs = filesize($fn);
$tor_fname = $row["filename"];

mysql_query("UPDATE torrents SET hits = hits + 1 WHERE id = $id");

require_once "include/benc.php";  // Torrent Encoding Functions

$dict = bdec_file($fn, (1024*1024));
$dict['value']['announce']['value'] = "$DEFAULTBASEURL/announce.php?passkey=$CURUSER[passkey]";
$dict['value']['announce']['string'] = strlen($dict['value']['announce']['value']).":".$dict['value']['announce']['value'];
$dict['value']['announce']['strlen'] = strlen($dict['value']['announce']['string']);

    header("Content-Type: application/x-bittorrent");
    header("Content-Disposition: attachment; filename=\"" . basename($tor_fname) . "\"" );
    print(benc($dict));

This is taken from (and is the majority of) the file download.php.  This is called like: download.php?id=??

The above should work, but when I use it, it tries to save the file as download.torrent, even though the $tor_fname variable doesn't contain that value.  I'd obviously like to force the filename to be '<filename>.torrent' rather than the same name as the php script with .torrent on the end.

Any ideas?  Am I doing something stupid, or is there some way of doing this?

Hi Guys,

I have an issue with the following script which is throwing this error

Quote

( ! ) Parse error: syntax error, unexpected end of file in C:\wamp64\www\script\images.php on line 41

I just can not see the error, can anyone help (not even sure the script is going to work)

<?php
/* settings */
//folder for images saving
$saveDir = "c:\wamp64\www\script\images\";

//database connection
// Turn off all error reporting
error_reporting(0);

$conn = mysqli_connect('localhost', 'root', '', 'tbl_temp_products');

//start and end table row to prevent timeout or hard server work
$start = '1';
$end = '200';
/* end of settings */

//query for fetching the image urls
$sql = 'SELECT image_url FROM tbl_temp_products ORDER BY id DESC LIMIT ' . $start . ',' . $end . '';
$res = $conn->query($sql);

$count = 0;          //this is for count the total row fetched
$notify = '';        //this is for seeing result or errors

while ($row = $res->fetch_assoc()) {
$url = $row(['image_url']);
$dest = $saveDir . clean($row(['image_url'])) . '.jpg';

if (!file_exists($dest)){   //prevent file overwriting
   if (copy($url, $dest)){
      $notify.= 'image saved: '. $row(['image_url']);
      $count++;
   }else{
      $notify.= 'ERROR saving image: '. $row(['image_url']);
   }else{
   $notify.= 'image already exists: '. $row(['image_url']);
   }
}
//output result
echo 'TOTAL IMAGE SAVED: ' .$count .'\n';
echo $notify;
?>

 

Hi, this is my first post:) pretty sure i will be posting here in the future. Anyway i am having trouble with a php script which downloads a file from a mysql database.

This php script works for text files and should work for most files from what i understand. When downloading a text file, the whole file is downloaded from the server. When downloading an mp3 file, only 16kb are downloaded and the file does not play. When looking at the data in the database, it displays that the full file is there (correct amount of bytes, so there is nothing wrong with my upload php script). Does anyone have any suggestions as to what I can change to make this work?

Code: [Select]
<?php
if(isset($_GET['id'])) 
{
// if id is set then get the file with the id from database
$link=mysql_connect('localhost', 'root', '');
@mysql_select_db('filemgr') or die ("<p>Could not connect to mysql!</p>");

$id    = $_GET['id'];
$query = "SELECT name, type, size, content " .
         "FROM upload WHERE id = '$id'";

$result = mysql_query($query) or die('Error, query failed');
list($name, $type, $size, $content) =  mysql_fetch_array($result);

header("Content-length: $size");
header("Content-type:$type");
header("Content-Disposition: attachment; filename=$name");
echo $content;

mysql_close($link);
exit;
}
?>

Ok, I have a download script. The script is called like:

http://www.site.net/index.php?action=downloadfile&filename=file001.zip&directory=directory12&

The download file code is below. My site hosts quite a few files that get linked on other websites. Problem is, when that link is clicked, obviously it just starts the file download, as if it were a direct link to the file.

What I need to do, is still have it download the file when the link is clicked, but I would also like it to redirect the browser to my homepage as well.

I tried placing this after the download headers but it didn't work.

header("Location: http://www.site.net");

Can anyone give me an idea how I can get the code to do that? Keep in mind that I'm not fluent in PHP.



case 'downloadfile';

$filename = getGetVar('filename');
$directory = getGetDir('directory');


$current_dir = $uploads_folder_name;
if ($directory != '')
{ $current_dir.="/$directory"; }


$filename = basename($filename);


if (!$grants[$user_status][DOWNLOAD])
{
place_header($mess[111]);
show_Contents();
break;
}


if (!file_exists("$current_dir/$filename"))
{
place_header($mess[125]);
show_Contents();
break;
}


if (!is_path_safe($directory, $filename))
{
place_header($mess[111]);
show_Contents();
break;
}


list($upl_user, $upl_ip, $filestatus, $contents) = get_file_description("$current_dir/$filename", $comment_max_caracters);
if ($validation_enabled && $filestatus == UNVALIDATED && !$grants[$user_status][VALIDATE])
{
place_header($mess[111]);
show_Contents();
break;
}



$size = filesize("$current_dir/$filename");
$daily_size = get_daydownload();
if (($max_daily_download_mb > 0) && (($size + $daily_size) > ($max_daily_download_mb * 1024 * 1024)))
{
place_header($mess[212]);
show_Contents();
break;
}


$monthly_size = get_monthdownload();
if (($max_monthly_download_mb > 0) && (($size+$monthly_size) > ($max_monthly_download_mb * 1024 * 1024)))
{
place_header($mess[213]);
show_Contents();
break;
}
increasefiledownloadcount("$current_dir/$filename");
increasebytecountdl("$destination/$userfile_name");
if (($user_status != ANONYMOUS) && ($logged_user_name != ''))  // Update user statistics
{
list($files_uploaded, $files_downloaded, $files_emailed) = load_userstat($logged_user_name);
$files_downloaded++;
save_userstat($logged_user_name, $files_uploaded, $files_downloaded, $files_emailed, time());
}


header("Content-Type: application/force-download; name=\"$filename\"");
header("Content-Transfer-Encoding: binary");
header("Content-Length: $size");
header("Content-Disposition: attachment; filename=\"$filename\"");
header("Expires: 0");
header("Cache-Control: no-cache, must-revalidate");
header("Pragma: no-cache");

// Decrypt file if encryption enabled
if ($encrypt_filecontent)
{ decrypt_file("$current_dir/$filename", true); }
else
{ readfile_chunked("$current_dir/$filename"); }


exit;
break;

Basically I would like to place a link on my website and have the user download a file, but rather than just right clicking and choosing save target as, the link must be clicked, on the next page the file is fetched and then the client can download the file. How would I go about setting this up please?

When the download appears the link that is produced doesn't show the actual download either, so users can't leech of it.

Thanks
