problem with xml and php

[farban]

I have two php files that simply need modifing so that they communicate with this xml file

 

<?xml version="1.0" encoding="UTF-8" ?>
<songs>
    <song filename="The Birthday Massacre - Nothing And Nowhere - 06 - Video Kid.mp3" track="Video Kid" artist="The Birthday Massacre" album="Nothing And Nowhere" />
    <song filename="The Birthday Massacre - Nothing And Nowhere - 07 - Over.mp3" track="Over" artist="The Birthday Massacre" album="Nothing And Nowhere" />
    <song filename="The Birthday Massacre - Nothing And Nowhere - 08 - Broken.mp3" track="Broken" artist="The Birthday Massacre" album="Nothing And Nowhere" />
    <song filename="The Birthday Massacre - Nothing And Nowhere - 09 - The Dream.mp3" track="The Dream" artist="The Birthday Massacre" album="Nothing And Nowhere" />
    <song filename="The Birthday Massacre - Nothing And Nowhere - 01 - Happy Birthday.mp3" track="Happy Birthday" artist="The Birthday Massacre" album="Nothing And Nowhere" />

</songs>

 

here is the two php files

 

upload.php

 

    <h1>Jukebox Playlist</h1>
    
    <p>Enter the Artist and Title names as you want them to appear on the jukebox. It'll take a few minutes to upload a song after you click submit, so leave it and don't close the page until you see it added to the Current Entries list.</p>

            <form action="playlistaction.php" method="post" enctype="multipart/form-data">
<table>
   <tr>  
     <td colspan="2"class="labelcell"><label for="artist">Artist:</label></td>
     <td colspan="2"class="fieldcell"><input type="text" id="artist" name="artist"  tabindex="1"/></td>
   </tr>
      <tr>  
     <td colspan="2"class="labelcell"><label for="title">Title:</label></td>
     <td colspan="2"class="fieldcell"> <input type="text" id="title" name="title"  tabindex="2"/><br />
</td>
   </tr>
        <!-- <tr>  
     <td colspan="2"class="labelcell"><label for="path">URL:</label></td>
     <td colspan="2"class="fieldcell"> <input type="text" id="url" name="url"  tabindex="3"/> <br />
</td>
   </tr>-->
   <tr>
<td colspan="2"class="labelcell"><label for="userfile">Song Upload</label></td>
    <td colspan="2"><input name="userfile" type="file" id="userfile"  tabindex="4"></td></tr>
     </td>
   </tr>
   <td colspan="4"><input type="submit" name="upload" class="box" value="Submit" tabindex="5" /></td>
  </table>
</fieldset>
</form>
<h2>Current entries:</h2>
<p>Artist - Title - URL</p>
<?php
$xml = simplexml_load_file("..songs/playlist.xml");

foreach($xml->songs[0]->attributes() as $a => $b)
  {
  echo $a,'="',$b,"\"</br>";
  }
?> 

?>

 

playlistaction.php

 

<?php
$uploadDir = 'Bulrush\songs';

if(isset($_POST['upload']))
{
$fileName = $_FILES['userfile']['name'];
$tmpName = $_FILES['userfile']['tmp_name'];
$fileSize = $_FILES['userfile']['size'];
$fileType = $_FILES['userfile']['type'];
$filePath = $uploadDir . $fileName;

$result = move_uploaded_file($tmpName, $filePath);
if (!$result) {
                echo "Error uploading file";
                exit;
              }

}

$song = array(
    'track' => $_POST['track'],
    'artist' => $_POST['artist'],
     'album' => $_POST['album'],
    'song filename' => $filePath,
);
    
$doc = new DOMDocument();
$doc->load( 'playlist.xml' );

$doc->formatOutput = true;
$r = $doc->getElementsByTagName("songs")->item(0);


$title = $doc->createElement("track");
$title->appendChild(
    $doc->createTextNode( $song["track"] )
);
$b->appendChild( $title );

$artist = $doc->createElement("artist");
$artist->appendChild(
    $doc->createTextNode( $song["artist"] )
);
$b->appendChild( $artist );

$artist = $doc->createElement("album");
$artist->appendChild(
    $doc->createTextNode( $song["album"] )
);
$b->appendChild( $artist );

$url = $doc->createElement("song filename");
$url->appendChild(
    $doc->createTextNode( $song["song filename"] )
);

$b->appendChild( $url );
$r->appendChild( $b );
    
$doc->save("player.xml");

    header("Location: {$_SERVER['HTTP_REFERER']}");    
?>
