Woocommerce wp_query get order by ID - php

Question

I am trying to produce a plain output of order data. First step is a WP_QUery (perhaps) so I write this code;
$args = array (
'post_type' =>'shop_order',
'posts_per_page' => -1,
'post_status' => 'any',
//'p' => $post_id,
);
$order_query = new WP_Query( $args );
while ( $order_query->have_posts() ) :
$order_query->the_post();
echo the_ID();
echo ' : ';
the_title();
echo '<br/><br/>';
endwhile;
It obliging products a list of all orders, if I set the 'p' => $post_id where $post_id is a valid post ID, the query returns nothing.
Any idea why, hive mind?
Alternatively is there a Woocommerce way of producing a plain page with a layout like;
Order ID: 836
Order Status: ....
I assumed a WP_Query would be the obvious way but it is appearing like getting woocommerce order data is anything but straightforward.

To get the order data for one order, you don't need WP_query. You can use directly:
$order = wc_get_order( $order_id );
$order->id; // order ID
$order->post_title; // order Title
$order->post_status; // order Status
// getting order items
foreach($order->get_items() as $item_id => $item_values){
// Getting the product ID
$product_id = $item_values['product_id'];
// .../...
}

You should try this, as with array_keys( wc_get_order_statuses() you will get all order statuses and with 'numberposts' => -1, all existing orders.
Here is an alternative way (without WP_query or you can use thoses args in the WP_query array):
$customer_orders = get_posts( array(
'numberposts' => -1,
'post_type' => 'shop_order',
'post_status' => array_keys( wc_get_order_statuses() )
) );
// Going through each current customer orders
foreach ( $customer_orders as $customer_order ) {
// Getting Order ID, title and status
$order_id = $customer_order->ID;
$order_title = $customer_order->post_title;
$order_status = $customer_order->post_status;
// Displaying Order ID, title and status
echo '<p>Order ID : ' . $order_id . '<br>';
echo 'Order title: ' . $order_title . '<br>';
echo 'Order status: ' . $order_status . '<br>';
// Getting an instance of the order object
$order = wc_get_order( $order_id );
// Going through each current customer order items
foreach($order->get_items() as $item_id => $item_values){
// Getting the product ID
$product_id = $item_values['product_id'];
// displaying the product ID
echo '<p>Product ID: '.$product_id.'</p>';
}
}

The strict answer to this question is change 'p'=>$post_id' to 'post__in' => array($post_id)
...but the real answer, should anyone be treading this path, is that parsing the email is so much easier, woocommerce has done most of the work for you. There are other pratfalls along the way; 1. The post is protected and the order notes are in the excerpt so can't be displayed ( I could move them to meta but...) 2. The order items are within comments and have to be looped then parsed to produce meaningful output, so I might as well parse the email direct.
