最好使用wc_get_order()函数，因为WooCommerce订单很快就会在WordPress数据库中拥有自己的表。
下面的简码只会为客户显示未审核的购买产品，假设在WooCommerce设置>产品>评论中，您已经启用了“评论只能由“验证所有者”留下”选项：

下面是代码：

// Utility function that get the reviewved products Ids of a customer
function get_customer_reviewed_products( $user_email ) {
    global $wpdb;

    // Returns an array of product Ids reviewed by the customer
    return $wpdb->get_col( "
        SELECT DISTINCT c.comment_post_ID 
        FROM {$wpdb->prefix}comments as c
        INNER JOIN {$wpdb->prefix}posts as p ON p.ID = c.comment_post_ID 
        WHERE c.comment_author_email = '{$user_email}'
            AND p.post_type = 'product'
    " );
}

// The custom products shortcode
add_shortcode( 'customer_products', 'customer_products_shortcode' );
function customer_products_shortcode() {
    if ( ! is_user_logged_in() ) {
        return;
    }

    $user = wp_get_current_user(); // GEt WP_User  object
    
    // Get customer orders
    $customer_orders = wc_get_orders( array(
        'limit'         => -1,
        'customer'      => $user->ID,
        'status'        => wc_get_is_paid_statuses(),
    ) );

    $product_ids = array(); // Initializing

    // Loop through customer orders
    foreach ( $customer_orders as $customer_order ) {
        // Loop through order items
        foreach ( $customer_order->get_items() as $item ) {
            $product_ids[] = $item->get_product_id();
        }
    }
 
    if ( empty($customer_orders) ){
        return;
    }

    // Get customer reviewed products ids
    $reviewed_ids = get_customer_reviewed_products( $user->user_email );
    
    // Keep only customer unreviewed purchased products
    $ids = implode( ',', array_diff( array_unique( $product_ids ), $reviewed_ids ) );
    
    return do_shortcode( "[products ids='$ids']" );
}

代码放在你的活动子主题（或活动主题）的function.php文件中。测试和作品。

用法：

在WordPress文本编辑器、小部件或块中：

[customer_products]

在PHP中：

echo do_shortcode("[customer_products]");
