WordPress MU

Hello guys

Basically I tried to change the default wp-admin/themes.php page behavior.

I wanted this page to display a list of categories and when clicked - it would display themes in that particular category.

I created folders inside wp-content/themes and I made the page wp-admin/themes.php display all these folders, then when clicked on - the page displayes all themes I have put there.

For example, I have wp-content/themes/favorites and the page wp-admin/themes.php displayes a link 'Favorites', when I click on it - it displayes all the themes I have put in wp-content/themes/favorites folder.

But now I got a problem. I cannot apply any of these themes in wp-content/themes/favorites to live blog.

What I did. I only changed wp-admin/themes.php

line 4, there was:

$themes = get_themes();

changed to:

if ( isset($_GET['folder']) ) $themes = get_themes($_GET['folder']);
else $themes = get_themes();

After line 47 I added:

<?php if ( isset($_GET['folder']) ) { ?>

After line 212 (214 in edited file) I added:

</div>

<?php } else { ?>

<div class="wrap">
<h2><?php _e('Themes folders:'); ?></h2>

<?php
	$theme_loc = $theme_root = get_theme_root();
	if ( '/' != ABSPATH ) // don't want to replace all forward slashes, see Trac #4541
		$theme_loc = str_replace(ABSPATH, '', $theme_root);

	// Files in wp-content/themes directory and one subdir down
	$themes_dir = @ opendir($theme_root);
	if ( !$themes_dir )
		return false;

	while ( ($theme_dir = readdir($themes_dir)) !== false ) {
	if (($theme_dir != ".")  && ($theme_dir != "..") && ($theme_dir != "home"))
  echo '<br /><a href="themes.php?folder='.$theme_dir.'">'. ucfirst(strtolower($theme_dir)) . '</a>';
}

?>

</div>

<?php } ?>

<?php require('admin-footer.php'); ?>

Well, the problem is that I cannot apply any theme located in any subdirectory of wp-content/themes/ to blogs.

Can anyone help?

I also tried this: http://heftagaub.wordpress.com/2007/05/27/common-themes-directory-for-multiple-instances-of-wordpress/

but could not get it working :(
