php - Hide (not remove) category name globally on wordpress blog -

i'm trying hide specific category name (e.g. called "featured") on whole wordpress blog. please note not want exclude post belongs specific category, want prevent actual category name showing anywhre, should invisible.

i found code snippet put in functions.php, , want, it's hiding category names post meta section, doesn't have effect on third party plugins category name still showing. can please in order worked specific plugin?

code in function.php hiding category name:

function the_category_filter($thelist,$separator=' ') { if(!defined('wp_admin')) {      $exclude = array('featured');     $cats = explode($separator,$thelist);     $newlist = array();     foreach($cats $cat) {         $catname = trim(strip_tags($cat));         if(!in_array($catname,$exclude))             $newlist[] = $cat;     }     return implode($separator,$newlist); } else     return $thelist; } add_filter('the_category','the_category_filter',10,2); 

plungin's function looks this:

private function generate_post_categories( $post ) {      // setting category list string.     $post_cat_string = '';      // setting category list.     $post_cat_list = '';      // fetching post category prefix  wpml support.     $post_category_prefix = ($this->icl_t) ? icl_t('orp post category prefix', 'post-category-prefix–' . $this->widget_id, $this->widget_args['post_category_prefix'] ) : $this->widget_args['post_category_prefix'];      // checking post category prefix.     if ( !empty( $this->widget_args['post_category_prefix'] ) ) {          // building post category prefix html.         $post_cat_string .= esc_html( $post_category_prefix );     }      // retrieving categories array.     $orp_categories = get_the_category( $post->id );      // checking if "post category link" option on.     if ( 'yes' == $this->widget_args['post_category_link'] ) {          // looping through categories array.         foreach( $orp_categories $orp_cat ) {              // fetching current category link.             $orp_category_link = get_category_link( $orp_cat->cat_id );              // building html link atts.             $linkatts = array(                 'href'  => $orp_category_link,                 'title' => $orp_cat->cat_name             );              // building category link html.             $post_cat_list .= $this->orp_create_tag( 'a', $orp_cat->cat_name, $linkatts ) . esc_html( $this->widget_args['post_category_separator'] );         }      } else {          // looping through categories array.         foreach( $orp_categories $orp_cat ) {              // filling categories list.             $post_cat_list .= $orp_cat->cat_name . esc_html( $this->widget_args['post_category_separator'] );         }     }      // right trimming last category separator on category list.     $post_cat_string .= rtrim( $post_cat_list, esc_html( $this->widget_args['post_category_separator'] ) );      // returning post category html.     return $this->orp_create_tag( 'div', $post_cat_string, array( 'class' => 'orp-post-category' ) ); 

could try change part:

// looping through categories array. foreach( $orp_categories $orp_cat ) { 

to :

// looping through categories array. foreach( $orp_categories $orp_cat ) {   if($orp_cat->cat_name == 'featured') {     continue;   } 

that should skip loop if category name equal "featured".
