At the heart of WordPress is the WP_Query class, used to retrieve practically all content from the database and prepare it for display. In this presentation, I’ll discuss the myriad arguments available with WP_Query, the various properties and methods that are automatically populated, and the advanced queries made possible through filters within the class. I’ll also review the pre_get_posts action, detail how it can be used to modify standard WordPress queries and completely eliminate query_posts(), and explain why you’d want to do so in the first place.
