Since I am upgrading my sites to the wonderful Conundrum/Ad Infinitum/Nosebleed themes, which are not yet compatible with Wordpress 2.3, I had to manually add the (only) feature which I find worth upgrading for: tags. In addition to categories, posts may now be tagged with certain keywords.

Adding to Conundrum/Ad Infinitum/Nosebleed. It is easy to upgrade the Conundrum/Ad Infinitum/Nosebleed themes: currently those themes show the categories in which the posts are put below each post. This is a line that starts with “Posted in”. The corresponding code in the Wordpress theme file is “Posted in < ? php the_category(', ') ? >“. To add tags, simply add the code “< ? php the_tags(); ? >” after the category code, and the tags you have entered for each post will appear like magic!

The files to edit in the Conundrum/Ad Infinitum/Nosebleed themes are index.php, archive.php, search.php and single.php.

Adding a tag cloud in the sidebar. A simple tag cloud can be added by editing sidebar.php and adding the following lines of code:

< ? php if ( function_exists('wp_tag_cloud') ) : ? >
< li >
< h2 >Popular Tags< /h2 >
< ul >
< ? php wp_tag_cloud('smallest=8&largest=22'); ? >
< /ul >
< /li >
< ? php endif; ? >

In the above codes make sure to delete the spaces after “<" and before ">“.
