   I'm using the the_category as a title for my post for the front page and I'm wondering if theres a way to exclude a category from the title because if i have more than 1 category it adds more to the title, or if anyone knows a alternative way to display the category name as the title. only one category displays on the front page, i need a to exclude that category so it shows only the only category i include with it.

   I'm having the same issue on the homepage of a site i am building.. There is a module called "Advanced Category Excluder" But it seems like overkill for something simple like this that can be handled with some php code..

   Here, i found this on google.

   <?php
   //edit below for categories you want excluded
   $exclude = array("Featured", "Uncategorized");
   //how do you want the list separated? just a space is okay
   $separator = " | ";
   //don't edit below here!
   $new_the_category = '';
   foreach((get_the_category()) as $category){
   	if (!in_array($category->cat_name, $exclude)){
   		$new_the_category .= '<a href="'.get_bloginfo(url).'/'.get_option('category_base').'/'.$category->slug.'">'.$category->name.'</a>'.$separator;
   	}
   }
   echo substr($new_the_category, 0, strrpos($new_the_category, $separator));
   ?>

   hope it helps.

   A nicer alternative building upon http://wordpress.org/support/topic/140469 but using category IDs instead of names, can be found here: http://www.smashingthemes.com/blog/how-to-remove-categories-from-the_category-function-in-wordpress/

   function the_category_filter($thelist,$separator=' ') {
       if(!defined('WP_ADMIN')) {
           //Category IDs to exclude
           $exclude = array(1,5);  
   
           $exclude2 = array();
           foreach($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;
       }
   }
   add_filter('the_category','the_category_filter', 10, 2);
