How to get all products from the database using WP_Query

To fetch all products from the database using WP_Query, you need to follow these steps:

1. First, define your query arguments. To get all published products without pagination, use this:

$args = array(
  'post_type'   => 'product',
  'post_status' => 'publish',
  'posts_per_page'    => -1
);

2. Next, create a new instance of WP_Query and pass in your query arguments:

$query = new WP_Query( $args );

3. Finally, you can loop through the results and operate on each product:

if ( $query->have_posts() ) {
  while ( $query->have_posts() ) {
    $query->the_post();
    global $product;

    // Operate on the $product variable here.
  }
  wp_reset_postdata();
}
