Wordpress the_category with Excludes


The WordPress function the_category doesn't offer an exclude parameter. This does:

function exclude_post_categories($excl='', $spacer=' ') {
  $categories = get_the_category($post->ID);
  if (!empty($categories)) {
    $exclude = $excl;
    $exclude = explode(",", $exclude);
    $thecount = count(get_the_category()) - count($exclude);
    foreach ($categories as $cat) {
      $html = '';
      if (!in_array($cat->cat_ID, $exclude)) {
        $html .= '<a href="' . get_category_link($cat->cat_ID) . '" ';
        $html .= 'title="' . $cat->cat_name . '">' . $cat->cat_name . '</a>';
        if ($thecount > 0) {
          $html .= $spacer;
        }
        $thecount--;
        echo $html;
      }
    }
  }
}

Plus as long as you have that, you can alter the output however you want which is nice.

Usage is like:

<?php exclude_post_categories("4"); ?>
