A Beginner’s Guide to Using WP_Query in WordPress

By default, WordPress automatically sorts your posts from newest to oldest. Although visitors can search for specific posts using categories and tags, they might not be able to find the content they’re looking for. To curate your posts for each visitor, it can be helpful to use WordPress WP_Query.

In this post, we’ll explain what WP_Query is. Then, we’ll show you how to use it on your WordPress website. Finally, we’ll give you some examples of ways to implement it on your blog. Let’s get started!

An Introduction to WP_Query

In WordPress, your site’s data is stored in a MySQL database. This includes everything from posts, pages, and comments, to your configuration settings.

WP_Query is a PHP class that you can use to construct queries for your database. In WordPress, this is a built-in class that occurs whenever someone searches your content.

However, implementing a custom WordPress query can enable users to find specific content without searching for it. If you need to render a particular group of posts on the front end of your site, you can easily do this using a WP_Query custom post type.

How to Use WordPress WP_Query (4 Ways)

Now that you know about WP_Query, let’s discuss how to create your first query. This way, you can quickly and easily customize your website display!

1. Create a Loop

You’ll need to be familiar with the WordPress Loop to get started. Based on the parameters you set, the Loop can display content from WordPress custom post types and custom fields, post titles and excerpts on your homepage, a single post’s content and comments, and individual page content using template tags.

Before customizing the Loop with WP_Query, you’ll need to know the Loop structure. Let’s break down the individual parts of this loop:

First, the function have_posts() will check to see if there are posts on your site. If so, the while condition continues the loop for every post. Essentially, this informs your database to display any posts on your website.

However, you might not want to display all your posts. By inserting WP_Query code into the Loop, you can enable WordPress to only render certain posts.

2. Use Arguments

When you structure your WP_Query, you need to include four basic elements: Query argument, Query itself, The Loop, and Post data reset. The argument informs WordPress what data you want to retrieve from the database.

3. Set Parameters

Setting parameters is important for customizing WP_Query. You can enable WordPress to retrieve a custom collection of posts from your database by specifying this information.

4. Modify Class Properties With Methods

WP_Query is a PHP class that contains constants called properties. Although it is not recommended to alter WP_Query properties directly, you can use methods to interact with them. Methods work similarly to functions. When you modify the methods of WP_Query, you can customize the data that is retrieved.

Examples of WP_Query

Once you learn the basics of WordPress WP_Query, you can start using it to customize your website design. Let’s discuss some common examples of WP_Query to give you some inspiration!

1. Latest Posts in a Certain Category

Generally, online users are most interested in new content. After visitors read one of your posts, you’ll want to provide some related content. By recommending more recent posts, you can direct users to other content they might enjoy.

2. Posts Published This Week

If you have a dedicated following, readers will want to read your newest articles as soon as they’re published. When you can design your website to feature recent posts, you can provide the most relevant information.

3. Popular Posts by Comment Count

Similarly, you can promote posts that most of your audience enjoyed. By informing users that another post received a lot of engagement, it can encourage them to click on the post to find out more.

4. Posts by the Same Author and Category

When visitors read your blog post, they may really enjoy that content. They might simply prefer the author’s writing style or the general topic. In this case, you can use WP_Query to offer similar post recommendations. This way, readers can click on additional articles to continue reading.

5. Author’s Yearly Posts

If you run a more prominent blog, you likely have many different authors who write posts. After someone reads one of your posts, they might want to find additional posts by that author more easily. In this case, you can list an author’s posts from the past year.

6. Preview Scheduled Posts

To give your audience a sneak peek of upcoming content, you can list your scheduled posts on your website. Using WP_Query, you can display the title and excerpts of your new posts.

Conclusion

WP_Query provides a simpler way to perform WordPress database requests. Using this PHP class, you can customize your site’s display and offer a unique experience for each online visitor.
