WP_Query is a package library in WordPress that allows users to retrieve posts by using arguments such as category, tag, author, date, and post type. It provides flexibility in retrieving and displaying content on a WordPress website.
Example 1: Retrieve all posts from a specific post type
$args = array( 'post_type' => 'product', );
$query = new WP_Query( $args );
In this example, we are retrieving all posts that are of the "product" post type.
Example 2: Retrieve posts from a specific category
$args = array( 'category_name' => 'news', );
$query = new WP_Query( $args );
This example retrieves all posts that are in the "news" category.
Example 3: Retrieve posts based on custom field value
In this example, we are retrieving all posts that have a custom field called "featured" with a value of "yes".
Overall, WP_Query is a powerful tool in retrieving posts from a WordPress website and is essential in creating custom queries for displaying content. It is part of the WordPress core package and does not require any additional libraries or packages.
