Using pieces of the forced download script, adding in MySQL database functions, and hiding the file
location for security was what we needed for downloading wmv files from our members creations
without prompting Media player as well as secure the file itself and use only database queries.
Something to the effect below, very customizable for private access, remote files, and keeping order
of your online media.
<?
# setup SQL statement
$sql = " SELECT id, fileurl, filename, filesize FROM ibf_movies WHERE id='
$_GET[id]' ";
# execute SQL statement
$res = mysql_query($sql);
# display results
while ($row = mysql_fetch_array($res)) {
$fileurl = $row['fileurl'];
$filename= $row['filename'];
$filesize= $row['filesize'];
$file_extension = strtolower(substr(strrchr($filename,"."),1));
switch ($file_extension) {
case "wmv": $ctype="video/x-ms-wmv"; break;
default: $ctype="application/force-download";
}
// required for IE, otherwise Content-disposition is ignored
if(ini_get('zlib.output_compression'))
ini_set('zlib.output_compression', 'Off');
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false);
header("Content-Type: video/x-ms-wmv");
header("Content-Type: $ctype");
header("Content-Disposition: attachment;
filename=\"".basename($filename)."\";");
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".@filesize($filename));
set_time_limit(0);
@readfile("$fileurl") or die("File not found.");
}
$donwloaded = "downloads + 1";
if ($_GET["hit"]) {
mysql_query("UPDATE ibf_movies SET downloads = $donwloaded WHERE id='
$_GET[id]'");
}
?>
While at it I added into download.php a hit (download) counter. Of course you need to setup the DB,
table, and columns. Email me for Full setup// Session marker is also a security/logging option
