I posted this at both devshed and mkportal's website and haven't recieved any help, sooo I thought I would try here, since everyone is so helpful. here's the thing I'm trying to write a block for mkportal, which that will display random file names for media files and random images for well images in from a standalone installation of coppermine. I'm still pretty new to php, so here's what I have so far.
block code


$sitepath = 'photo'; 
//the name of your coppermine gallery folder without a trailing slash
$dbprefix = 'cpg143_'; 
// prefix of your coppermine tables, don't forget the _ underscore

$query = $DB->query("SELECT pid, aid, title, filepath, filename FROM
 {$dbprefix}pictures ORDER BY RAND() LIMIT 1"); 

$photo = $DB->fetch_row($query);
$aid  = $photo['aid'];
$title  = $photo['title'];
$filepath = $photo['filepath'];
$filename = $photo['filename'];	
$thumbnail = "thumb_$filename";
$position = strlen($fileName) - (strpos($fileName, "."));
$extension = substr($fileName, -$position+1, $position);

$media = array ( "midi", "mid", " midi", "mpga", "mp2", "mp3", "aif", "ram",
 "rm", "ra", "wav","mpeg", "mpg", "qt", "mov", "avi"); 
$image = array ("gif", "jpeg", "jpg", "png", "bmp"); 

$false = '<div align="center"><b>No Files In the gallery<b></div>'; 

if ($extension == $media){

$content = '<tr align=\"center\"><td>
  <a href=\"{$sitepath}/thumbnails.php?album={$aid}\">$filename</a></td>
              </tr> 
              <tr>
			  <td id=\"tdblock\" align=\"center\" 
			  style=\"text-align:center; text-decoration: none;\">
		      <a href=\"{$sitepath}/thumbnails.php?album={$aid}\">
			  $title</a><br /></td>
			  </tr>'; 
} 

elseif ($extension == $image) {
  $content = '<tr align=\"center\"><td><a href=\"{$sitepath}/
  thumbnails.php?album={$aid}\">
              <img src=\"{$sitepath}/albums/{$filepath}{$thumbnail}\"
			   border=\"0\" alt=\"{$title}\"></a>
              </td></tr><tr><td id=\"tdblock\" align=\"center\" 
			  style=\"text-align:center; text-decoration: none;\">
              <a href=\"{$sitepath}/thumbnails.php?
			  album={$aid}\">$title</a><br /></td></tr>';  
} 
else {
  $content = $false; 
};  

unset($photo);
    unset($aid);
    unset($title);
    unset($filepath);
    unset($filename);
    unset($thumbnail);

I'm very new to scripting php and I can't understand why this won't work. I recieve no errors it's just that the block always shows this part


$content = '<div align="center"><b>No Files In the gallery<b></div>';

it won't display any files. Does anyone have any ideas?
Thanks in advance,
Angel
