How to Add Post Tags and Categories to Pages in WordPress

You can add categories to pages, which is fairly simple. To do this, simply add the following to the end of your functions.php file:

[php]
add_action( 'init' , 'wps_add_cats_to_page' );
function wps_add_cats_to_page() {
register_taxonomy_for_object_type('post_tag', 'page');
register_taxonomy_for_object_type('category', 'page');
}
[/php]
