WordPress exclude categories from the_category This is an update to an excellent old post on wordpress.com that partially explains how to exclude categories from the_category() function in WordPress. ocshawn’s solution half way down the page worked with a few small adjustments. Add the following to your WP functions.php (ideally in a child theme): function exclude_post_categories($excl=''){ $categories = get_the_category($post->ID); if(!empty($categories)){ $exclude=$excl; $exclude = explode(",", $exclude); $html = ''; foreach ($categories as $cat) { if(!in_array($cat->cat_ID, $exclude)) { $html .= ' $html .= 'title="' . $cat->cat_name . '">' . $cat->cat_name . ', '; } } echo substr($html, 0, strrpos($html, ', ')); } } then when you need to call the function use exclude_post_categories('1,2,17'); where ‘1,2,17’ are the category codes you want to omit. Note: one crucial thing not mentioned here is that permalinks must be of the default form ( ?p=123 ) so that category numbers are identified by the code.
