TOPIC:

I am trying to display customer order details as i have implemented all the steps mention in the tutorial www.wpblog.com/display-woocommerce-customer-order-details/ but still i am not having the actual output.

I have taken order id as same implemented there but not having a exact output that shown.
$order_id
$order_meta = get_post_meta($order_id);

Dear AlexanderBiscajin,
What information do you want to display exactly? The order number assigned by our plugin should be available as
There is no need to work with the internals of our plugin, but it's much better to use the API defined by WooCommerce (get_order_number() works with our plugin and it should also work with other order number plugins....)

BTW, if you really need to access the order meta data, you should do something like:
On the other hand, WooCommerce 3.0 added some more functionality to access internal data through the WC_Order object rather than accessing the (internal) order meta manually. This has to be seen in light of future compatibility: Just because certain things are currently stored as post meta does not mean that they will always be stored as post metas. Providing a nice, clean API at the WC_Order level provides an abstraction between accessing the data and how the data is stored internally.

Best regards,
Reinhold

Problem solved.
