By default, the WordPress category widget does not display empty categories. Recently a new user asked us if it is possible to display empty categories in the WordPress widget to help him with his local development. In this article, we will show you how to display empty categories in WordPress widgets.
The first thing you need to do is add this simple code snippet to your child theme's functions.php file or a site-specific plugin.
add_filter ('widget_categories_args', 'wpb_force_empty_cats'); función wpb_force_empty_cats ($ cat_args) $ cat_args ['hide_empty'] = 0; devuelve $ cat_args;
This code hooks our custom function.
widget_categories_args filter. Inside our function we have modified the option.
hide_empty and make it false.
That's it, now you can drag and drop the categories widget to any sidebar or widget area on your WordPress site. The category widget will now display empty categories as well.
If you're working in a local development environment, we recommend that you add dummy content to your website for testing.
