Course: WordPress Theme Development (Core Concepts)

person learning wordpress theme development

Welcome! WordPress themes are one of the most important topics that one must understand to be good at WordPress development. Themes underlie the entire visual half of WordPress sites, but often grow to do even more. Because of the visual importance, they’re a great place to dive in if you’re interested in getting to the “code-side” of WordPress. I myself “cut my teeth” on WordPress themes back in 2007 and 2008. WordPress themes were where I started to come to grips with the power (and limits) of PHP, CSS, and HTML. So this course is great for newbies, and those just looking to confirm their understanding of the whole system.

It’s been possible since WordPress 4.1, which introduced of a new filter, script_loader_tag.

What I’d really love to do is change just the search field in that template, depending on whether a particular page is showing a top-level category or a subcategory.


Practical Uses of pre_get_posts

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.
