Basically, WordPress doesn’t list the empty categories in its category list. Then how to show empty categories in the category list?. In this note, I’d like to share a simple script for this problem.
In WP, we’re using wp_list_categories() to lists the categories. There is an argument in this function called hide_empty, by default its value is TRUE. By this script, we are setting hide_empty‘s value as FALSE. So we can list empty categories with other categories.
Open your functions.php file and copy-paste this script. It’ll list your empty categories.
function all_cates($args)
{
$args['hide_empty'] = 0;
// you can override any other defaults here too
return $args;
}
add_filter( 'widget_categories_args', 'all_cates' );
This script was successfully tested in WordPress 3.2.1. if you like to know more about wp_list_categories() check out WP Codex. Happy blogging 🙂
