Generating playlist for jplayer in php - php

Question

i am actually working on this mentioned title. player show the list, its generating perfectly. but i am no where to make it actually play that file. i must be wrong some where.
i need advise fox. (ahh if i can attach the files.)
my class
class DecodDir
{
function getFiles($directory)
{
$all_files = array();
$handler = opendir($directory);
while($files=readdir($handler))
{
if($files!="." && $files!="..")
{
$all_files[]= $files;
}
}
closedir($handler);
return $all_files;
}
}
################# file where i am using this class *###############
<?php
include("decoddir.php");
$obj = new DecodDir();
$results = $obj->getFiles("mp3");
$total = count($results);
$string = "";
for($i=0; $i<$total; $i++){
$string .="
{
name:'$results[$i]',
mp3:'mp3/$results[$i]',
ogg:'$results[$i]'
},
";
}
?>
// its at the top of that html file (ofcorse with the php ext)
and below, this is where it is generating the playlist
var audioPlaylist = new Playlist("2", [
<?php echo $string; ?>
],
http://www.jplayer.org/latest/demo-02/ (the link from where i get jplayer) you can see the audio player with playlist.
(actually i don't know hot format the code in here stackoverflow)
thanks

I have taken the liberty of re-factoring the code a bit for you. I don't know exactly what you are trying to do, but it will help to have the beginnings of a better class on your side.
<?php
class DecodDir
{
private
$directory,
$files;
public function __construct( $directory = null )
{
if ( ! is_null($directory) )
{
$this->setDirectory( $directory );
}
}
public function setDirectory( $directory )
{
$this->directory = $directory;
$this->files = null;
// TODO put some validation in here;
return $this;
}
public function getDirectory()
{
if ( is_null($this->directory) )
{
$this->directory = './';
}
return $this->directory;
}
private function getFiles()
{
if ( is_null($this->files) )
{
$this->files = array();
$handler = opendir( $this->getDirectory() );
while($files=readdir($handler))
{
if($files!="." && $files!="..")
{
$this->files[]= $files;
}
}
closedir($handler);
}
return $this->files;
}
public function getJson()
{
$list = array();
foreach ( $this->getFiles() as $filename )
{
$item = new stdClass();
$item->name = $filename;
$item->mp3 = "mp3/{$filename}";
$item->ogg = $filename;
$list[] = $item;
}
$json = json_encode( $list );
return $json;
}
public function countFiles()
{
return sizeof( $this->getFiles() );
}
}
$obj = new DecodDir( 'mp3' );
echo $obj->getJson();

I wrote the code at the following site to do what you are trying to do, I think:
http://jplaylister.yaheard.us/
Sadly, it doesn't currently collapse a song stored in multiple formats (mysong1.mp3, mysong1.ogg) into one playlist item, but otherwise it is pretty feature-complete and has lots of customizable options.
Hope this helps!
