Finally, I found found the time to do some much needed work on some of my plugins. the first to receive an update is Ultimate Category Cloud (UCC) which now moves to version 3 and is fully Wordpress 2.3 compatible among other things.

Changelog

• Now WP2.3 compatible, thanks to Mephisto, Jason Ellis and Jan Weinschenker for their suggestions.
• Now displays weight and coloured categories as default behaviour
• Default ‘largest’ size is now 200% not 250%
• Removed the get_all_cats function, it is no longer needed
• New function for better conversion of hex colours to decimal values
• Font size weight should now more accurately reflect the largest and smallest font sizes that you specify
• Reworked weighted colouring, now only requires you to specify one colour.

Installation and Usage

To install UCC simply download the zip file below, extract the contents and upload to the wp-content/plugins directory on your server.

The display a ‘cloud’ on your site simply modify your theme to insert one of these snippets of code where you would like the ‘cloud’ to appear.

Default Weighted and Colored

<?php weighted_categories(); ?>

Weighted but not Colored

<?php weighted_categories(1,0); ?>

Colored but not Weighted

<?php weighted_categories(0,1); ?>

Neither Weighted nor Colored

<?php weighted_categories(0,0); ?>

To choose your own color add the third parameter

<?php weighted_categories(1,1,$basecolor="#ff0000"); ?>

Advanced usage

You can also specify how large or how small the weighted text should appear, if needed you can also exclude specific categories from the cloud, and by changing the $method option to ‘0′ you can reverse the coloring of the categories (ie. the lightest becomes the darkest and vice versa
<?php weighted_categories($weighted=1, $colored=1, $basecolor="#CCCCCC", $smallest=70, $largest=200, $unit="%", $exclude='', $method=1); ?>
