the_category as title exclude category

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);
