By default when you view the list of post categories or WooCommerce product categories, WordPress doesn’t show the IDs. But sometimes, you may need those IDs, say when you want to put them in a shortcode.
In this tutorial, we will build a small plugin that will show the category IDs on post and product category list.
As usual, let’s start by writing a plugin header so that WordPress treats our file as a plugin.
The Plugin Code
The plugin is really simple and self-explanatory, so I am not breaking it down further.
You may download the code from GitHub.
