Re: Can Netjuke create MP3s on the fly?

Hello,
    I think that I found a solution to this problem.  Here is my latest  
version of playmp3.php:


<?

$filename = $_REQUEST['mp3file'];
$tr_name = (isset ($_REQUEST['tr'])) ? rawurldecode($_REQUEST['tr']) :  
'Netjuke playlist';
$ar_name = (isset ($_REQUEST['ar'])) ? rawurldecode($_REQUEST['ar']) :  
'';
$al_name = (isset ($_REQUEST['al'])) ? rawurldecode($_REQUEST['al']) :  
'';

$bitrate = 64; // desired streaming bitrate
header("Content-type: audio/mp3");
set_time_limit(1800); // maximum length of a song

$tr_name = addcslashes($tr_name, ' ');
$ar_name = addcslashes($ar_name, ' ');
$al_name = addcslashes($al_name, ' ');

$filename = addcslashes($filename, ' ');

$tr_name = addcslashes($tr_name, '&');
$ar_name = addcslashes($ar_name, '&');
$al_name = addcslashes($al_name, '&');

$filename = addcslashes($filename, '&');


$tr_name = addcslashes($tr_name, ')');
$ar_name = addcslashes($ar_name, ')');
$al_name = addcslashes($al_name, ')');

$filename = addcslashes($filename, ')');

$tr_name = addcslashes($tr_name, '(');
$ar_name = addcslashes($ar_name, '(');
$al_name = addcslashes($al_name, '(');

$filename = addcslashes($filename, '(');

$tr_name = addcslashes($tr_name, '/');
$ar_name = addcslashes($ar_name, '/');
$al_name = addcslashes($al_name, '/');

$tr_name = addcslashes($tr_name, '-');
$ar_name = addcslashes($ar_name, '-');
$al_name = addcslashes($al_name, '-');

$filename = addcslashes($filename, '-');



echo passthru("/usr/local/bin/lame --add-id3v2 --ta $ar_name --tl  
$al_name --tt $tr_name -b $bitrate -f --silent  
/data/www/html/netjuke/$filename - ");
?>
