Show Category Name in Post

put the code below in your theme’s functions.php file. It designates certain categories that will not display in the cat listing, even if a post is assigned to them. See more instructions below

function the_category_filter($thelist,$separator=' ') {
	if(!defined('WP_ADMIN')) {
		//Category IDs to exclude:  Homepage, Homepage Featured, Also Featured
		$exclude = array(21,22,38);
		$exclude2 = array();
		foreach($exclude as $c) {
			$exclude2[] = get_cat_name($c);
		}
		$cats = explode($separator,$thelist);
		$newlist = array();
		foreach($cats as $cat) {
			$catname = trim(strip_tags($cat));
			if(!in_array($catname,$exclude2))
				$newlist[] = $cat;
		}
		return implode($separator,$newlist);
	} else {
		return $thelist;
	}
}
// when adding cats to exclude list, last parameter (below) to match # of excluded cats
add_filter('the_category','the_category_filter', 10, 3);

Change this line
$exclude = array(21,22,38);
make the contents of the array a comma separated list of the category ID’s you want to exclude from displaying.

The change this line
add_filter('the_category','the_category_filter', 10, 3);

the last “3” should be replaced with the # of cats you have entered in in the array list – for two cats, change the 3 to a 2.

With this method the cats that are excluded are global across the whole site, not on a post by post basis.

Works great! I really appreciate it. Thank you!
