编写一个函数来输出WooCommerce的特色产品

function get_featured_products() {
    $args = array(
        'post_type'      => 'product',
        'post_status'    => 'publish',
        'posts_per_page' => -1,
        'tax_query'      => array(
            array(
                'taxonomy' => 'product_visibility',
                'field'    => 'name',
                'terms'    => 'featured',
            ),
        ),
    );

    $query = new WP_Query( $args );

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

            // 输出产品信息
            echo '<h2>' . get_the_title() . '</h2>';
            echo '<div>' . $product->get_price_html() . '</div>';
            echo '<div>' . get_the_excerpt() . '</div>';
        }
    }

    wp_reset_postdata();
}

add_action( 'init', 'get_featured_products' );
