How-To: Get meta data from the users last order in woocommerce

First thing is to grab the last order ID, you can do it with a simple WP_Query

$args = array('post_type'=>'product',
                 'posts_per_page'=>1,
                 'orderby'=>'ID',
                 'orderby'=>'DESC');
$query= WP_Query($args);

As this will only give only one result, you don’t need to loop the result,

$order_id= $query->posts[0]->ID;

Now, you can reach the order data,

$order = WC_Order($order_id);

You can use the object with any woocommerce order related functions.

Hope it helps.
