Alright, it’s time to continue our journey building our awesome
WP_Query_Builder class! So far, we’ve only designed it to build simple WordPress queries. But not all WordPress queries are simple or easy to model using just a cascading method.
It’s even possible that you’ve run into the limits of the
WP_Query_Builder already. The class that we created then wasn’t a complete solution. It had some serious limitations if you were a
WP_Query expert. You couldn’t use it to perform complex WordPress queries.
What do we mean by complex WordPress queries? We mean queries that use a complex
WP_Query query parameters. At the moment, there are three of them:
So, for this article, we’re going to back to our
WP_Query_Builder class. We’ll add support for one of these complex
WP_Query query parameters. We won’t go over all three due to how complex they are. But you can apply what you’ve seen for this one query parameter to design a fluent interface for the other two.

In a previous article, we looked at how you could create a class to manage WordPress posts. We ended creating a class who’s job it was to interact with the WordPress database. And it did that quite well!
As part of its job, our class also had to be able to query the WordPress database. To do that, we made it easier to reuse code around the
WP_Query class. We achieved that by creating methods that used predefined query arguments.
But have you ever looked at the codex page for
WP_Query? Holy Moley, there are a lot of query parameters in there! It’s pretty intimidating and not always easy to use in practice.
That’s the problem that we’re going to look at in this article. We’ll design a class to simplify how we build
WP_Query objects. It’ll handle all the complexity around
WP_Query query parameters for you. The result should be an easier way for you for you to create WordPress queries.
