WordPress Quicky: Exclude Categories

Another quicktipp for wordpress theme developers.

If you want to exclude one or more categories from a page (startpage, category-page), you can call the query_posts function with negative category-ids …

<?php query_posts($query_string . '&cat=-1,-2,-3'); ?>
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
    <!-- POST -->
<?php endwhile; endif; ?>
