Want to know how to include a JavaScript file onto your WordPress site? In this Quick Quide we use an awesome WordPress function called wp_enqueue_script() that is the correct way to include JavaScript files in WordPress. Whether your JavaScript files are for Vue, React, JQuery, or something else, this is how you include JavaScript files in WordPress pages.

This WordPress plugin development tutorial captures the steps I went through on a real project, including the mistakes I made and how I debugged them.

I recently needed to modify a JavaScript file in a WordPress parent theme. The script was doing almost what I wanted, but not quite, so I wanted to make minor changes. In your case, you might want to entirely override a parent theme JavaScript file in your child theme, or even deactivate a parent theme JavaScript file altogether.

WordPress template tags are a super-important and super-valuable part of WordPress, especially for theme development. They’re also one of the things I remember spending lots of time not quite getting as I was learning WordPress.

Today’s article continues our discussion of WordPress’s Hooks system with a practical look at the direct opposite of add_action() and add_filter(): remove_action() and remove_filter().

Drew Jaynes has a pretty neat post up about some features you may not have noticed in WordPress 4.6. I have to admit that I’d not been paying super close attentions to everyone’s release notes posts, but this stuff was almost completely new to me. The most significant to me (by far) of Drew’s list is the last:

In WordPress, pre_get_posts is an action that makes it possible to modify an existing WP_Query, before that query is actually run. pre_get_posts offers some solutions that are more performant than writing a custom WP_Query, and enables solutions to other problems that would be quite difficult otherwise.

Today I’m going to discuss a new, and very nice, site speed improvement that became possible in WordPress 4.1. What changed? The introduction of a new filter, script_loader_tag. This filter lets us easily change the HTML markup of enqueued script elements—that is, of JavaScript files that were correctly added into a WordPress site using WordPress’s wp_enqueue_script function.

There’s not really a shortage of ways to find WordPress hooks, filters, functions, and more. It was actually Jeff Chandler’s story about Hookr.io — a new entrant into the field — that reminded me of this one which I remember from years ago. It’s not especially pretty, but it’s a deep resource that makes it easy to jump from a list of hooks to where they sit in the source once you get the hang of it.
