Say you have a category page on which you’re asked to display all the posts that belong to that category’s subcategories. So far no sweat – a category page displays by default all its descendant posts, whether they belong directly to that category or any of its subcategories. But here’s the twist: say you have to display them in such a way that the subcategory names are displayed (challenge no. 1), and under each subcategory’s name you have to display all its posts (challenge no. 2).

Making a widget to show a random post uses two underlying concepts you need to get familiar with to be good at WordPress development: making use of WP_Query objects, and making widgets. If you’ve not checked them before, check out our Quick Guides which more thoroughly introduce both:

There are lots of situations where you might want to change a WordPress post’s author. Fortunately, changing the author of a post (of any post type—Post, Page, or any custom post type) is easy to do if you know where to look.

We’ll cover two different ways that when given a page on a WordPress site you control. First I’ll cover how to find the WordPress post ID with the web page’s HTML, then we’ll locate the numeric ID of the post by editing that post.

In this video and text Quick Guide, we present a basic use of WP_Query inside a WordPress shortcode, to show the post titles of the five most recently published posts.
