Scriptaculous Inline Edit in a php script to create mp3 playlists

Well,

I got tired of linux mp3 players and their inability to manage mp3s, so I broke down
and started doing what I have been planning for along time, creating a mp3 playlist
creator to run on my local server.

I may release it as a script, as so far, it’s pretty useful, but one thing
that came up was, some of the mp3 filenames were not exactly clear. Like Track 13.mp3.
I firmly believe in the mp3 naming standard of Artist ft. Others - Song Name - Alblum.mp3.

In order to do this with the script I got a fantabulous idea, let’s use scriptaculous to edit
them in place, making it feel a bit more like an application.

I load all the files into an array, choosing the chunk I am going to list. Note, if you
have thousands of mp3s, do not try to create thousands of inline edits, it will crash, seriously
I tried it.

Instead, I paginate my files so I can surf through them easily, checking off the ones I want
to add to my playlist, then the script moves them to the specified folder.

  <script src="javascripts/prototype.js"></script>
  <script src="javascripts/scriptaculous.js?load=effects,controls"></script>
  <script type="text/javascript" language="javascript">
    // <![CDATA[
      Event.observe(window, 'load' , function() {
        <?php 
        for ($i = $start; $i <= $limit;$i++) {
          ?>
            new Ajax.InPlaceEditor('song_<?php echo $i;?>', 'rename.php?action=rename&dir=<?php echo $_GET['dir'];?>');
          <?php
        }
        ?>
      });
 
    // ]]>
  </script>

There we go, now, I just loop through the array of songs, and place things in a paragraph
with the necessary id:

  <table>
    	<?php 
        //This is the equivalent of say for instance cycle. It can
        //be done a million different ways, this is one of them.
        //It allows for an alternating background color.
        $x = 0;
        for ($i = $start; $i <= $limit;$i++) {
          switch ($x) {
            case 0:
              $x = 1;
              $style = 'table-odd';
              break;
            case 1:
              $x = 0;
              $style = 'table-even';
              break;
          }
          ?>
            <tr>
              <td valign="top" colspan="3">
              <a name="<?php echo $i;?>" />
                <table class="<?php echo $style;?>" width="100%">
                  <tr>
                    <td valign="top" width="3%"><?php echo $i;?></td>
                    <td valign="top" width="2%"><input type="checkbox" name="song_nums[]" value="<?php echo $i;?>"> </td>
                    <td valign="top" width="45%">
                      <p id="song_<?php echo $i;?>"><?php echo $songs[$i];?></p></td>
                    <td valign="top"><a href="delete.php?dir=<?php echo $_GET['dir'];?>&file=<?php echo urlencode($songs[$i]);?>&anchor=<?php echo $i;?>">Delete</a></td>
                  </tr>
                </table>
              </td>
            </tr>
      <?php
        }
      ?>
    </table>

If someone wants me to post the whole script when it’s done, I will.
