As a WordPress developer, you may find yourself in need of retrieving user data from your site’s database. This is where the WP_User_Query class comes in handy. This class allows you to easily query your database for users based on various parameters, such as roles, meta data, and search criteria.
The WP_User_Query class extends the WP_Query class, which means it shares many of the same parameters and methods. However, there are some differences that are specifically tailored to user queries.
To use the WP_User_Query class, simply instantiate a new object with the parameters you want to search for and call the get_results() method to retrieve the user data.
Here’s an example usage code:
$args = array( 'role' => 'author', 'meta_key' => 'favorite_color', 'meta_value' => 'blue', ); $user_query = new WP_User_Query( $args ); $authors_with_blue_favorite_color = $user_query->get_results();
In this example, we’re searching for all users with the "author" role who have a favorite color of "blue" stored as user meta data.
Overall, the WP_User_Query class is a powerful tool for retrieving user data from your WordPress site’s database.
