This free WPShout Course is a step-by-step introduction to WP_Query, one of the most powerful systems in WordPess. By the end of the course, you’ll know what a WP_Query is, and how and why to use your own custom WP_Querys for theme and plugin development. It really is a revolutionary and powerful tool for every WordPress theme and plugin developer to master 🙂


Getting to Know WP_Query

The WP_Query class is an exceptionally powerful tool in WordPress. As you may know, every WordPress site contains a database that stores many posts (of many post types) that make up the bulk of that site’s content, and WP_Query is the best way to fetch or retrieve a given selection of those posts for processing. So your theme files use it on regular basis, and a lot of plugins on your WordPress site will it.


How to Schedule Post Revisions in WordPress

We’ve covered before that you can schedule design changes to your site from the WordPress Customizer. A weird limitation, though, it that you can’t schedule revisions to posts (or pages, or other custom post types). Well, you can’t do that out-of-the-box. Which is where this here Quick Guide comes in: we’ll use a plugin to make it possible for you to schedule things like small updates to WordPress posts and pages to go live at a later time. Scheduling WordPress post revisions is a cool super power, and it’s great the PublishPress Revisions plugin makes it possible.

This article introduces one of the most important topics in WordPress development: WordPress hooks, including action hooks and filter hooks. Hooks are at the core not only of how WordPress plugins work, but nearly all code in the WordPress ecosystem: most WordPress themes use hooks heavily, as does “WordPress core” itself. WordPress hooks are absolutely a must-know topic in WordPress development.




A Story of WP Option Autoload: A wp_options Cleanup

Today I want to dive into a kind of esoteric topic: WP option autoloading. It’s not something a lot of WordPress developers are likely to hit or to need. But vague knowledge of this topic saved me a bunch of time and confusion on a client project, so I want to help you understand how casual use of the update_option function without understanding WordPress’s autoload options feature can cause you pain and heartache.
