List Terms for Category and Exclude Terms via Array()

May 26, 2015

function my_get_the_term_list( $id = 0, $taxonomy, $before = '', $sep = '', $after = '', $exclude = array() ) {
	$terms = get_the_terms( $id, $taxonomy );

	if ( is_wp_error( $terms ) )
		return $terms;

	if ( empty( $terms ) )
		return false;

	foreach ( $terms as $term ) {

		if(!in_array($term->term_id,$exclude)) {
			$link = get_term_link( $term, $taxonomy );
			if ( is_wp_error( $link ) )
				return $link;
			$term_links[] = '<a href="' . $link . '" rel="tag">' . $term->name . '</a>';
		}
	}

	$term_links = apply_filters( "term_links-$taxonomy", $term_links );

	return $before . join( $sep, $term_links ) . $after;
}

Place the above code inside of functions.php and wherever needed add the following into your template files:

<p>Posted in <?php echo my_get_the_term_list( $post->ID, 'your-category-name',  '', ' ', '', array(18) ); ?> By <?php the_author(); ?></p>

Update with the relevant category name, and remember to include the IDs for the categories you wish to exclude.
