Renaming Download File Using Header in PHP - php

Question

i have a link pointing to a music file on my site, now the name of the file was hashed when it was uploaded so i want to use the original filename which i have stored in my database, I did some research and found this new 'download' attribute for the 'a' tag but that only works in later versions of firefox and chrome, it doesn't work in ie and also doesn't work with the download manager i use so i checked online and found out about headers which i then implemented. I now get the filename changed allright but the music file keeps on getting saved as a '11.35kb' filesize no matter the music file i try to download. This is my code:
if (isset($_REQUEST['download']))
{
$download_id = $_REQUEST['download'];
$db = new MysqliDatabase(ConnectionString);
$result = array();
$result = $db->query_one("SELECT TrackID, ma.ArtisteName, FeaturedArtistes,
mc.Category, TrackName
FROM `musictracks` mt
LEFT JOIN `musiccategories` mc
ON mt.CategoryID = mc.CategoryID
LEFT JOIN `musicartistes` ma
ON mt.ArtisteID = ma.ArtisteID
WHERE mt.TrackID = '$download_id';");
$filename = $result->TrackPath;
$outputfilename = $result->ArtisteName . ' ft. ' . $result->FeaturedArtistes . ' - ' . $result->TrackName . '.mp3';
header("Content-Type: audio/mpeg");
header("Content-Disposition: attachment; filename=\"" . basename($outputfilename) . "\";" );
header("Content-Transfer-Encoding: binary");
readfile("$filename");
}
And this is the download link:
<a href="<?php echo 'musicdownload.php?download='. $row->TrackID ?>" ><img src="images/download.png" alt="download" title="download" width="14" height="14" /></a>

Answer 1

My PHP is a bit rusty but I can think of one thing with your code, no content length header. Update your code to this and see if that works:
if (isset($_REQUEST['download'])) {
{
$download_id = $_REQUEST['download'];
// ...
$filename = $result->TrackPath;
$outputfilename = $result->ArtisteName . ' ft. ' . $result->FeaturedArtistes . ' - ' . $result->TrackName . '.mp3';
if (file_exists($filename)) {
header("Content-Type: audio/mpeg");
header("Content-Disposition: attachment; filename=\"" . basename($outputfilename) . "\";" );
header("Content-Transfer-Encoding: binary");
header('Content-Length: ' . filesize($filename));
ob_clean();
flush();
readfile($filename);
exit;
}
}
}
Note that we use flush(); to send the headers to the browser before we start downloading the actual file. And I also added an if (file_exists($filename)) to make sure we have a file to send. I'd recommend you put an else clause there to give you something that will show you if you don't have a file like you expect...

Answer 2

header("Content-Type: application/force-download");
header("Content-Type:audio/mpeg");
header("Content-Type: application/download");;
header("Content-Disposition: attachment;filename=".$file_name);

Answer 3

Please download your mp3 files using curl
Here is sample code for your reference
<?php
if(isset($_REQUEST['inputurl']) && $_REQUEST['inputurl']!="") {
$file = $_REQUEST['inputurl'];
header("Content-type: application/x-file-to-save");
header("Content-Disposition: attachment; filename=".basename($file));
readfile($file);
}
?>
<form name="from" method="post" action="">
<input name="inputurl" type="text" id="inputurl" value="" />
<input type="submit" name="Button1" value="Get File" id="Button1" />
</form>
may be it will help you.
