How to structure a multi array to process and sort WooCommerce Order Item data? - arrays

Question

How can I extract details from an order into an array, while on the "Order Edit" page and then loop through them?
My array structure isn't correct as can't handle a 3rd item-detail. So each order item somehow needs to be placed into its own sub-array.
Then I want to be able to sort them on item-name and print them out with an echo.
How to achieve the correct array structure to input them and extract?
add_action( 'woocommerce_admin_order_data_after_shipping_address', 'additional_admin_order_data_block_after_shipping_address', 100 );
function additional_admin_order_data_block_after_shipping_address(){
echo '</div><div class="order_data_column order_packing_column">
<h3>' . esc_html__( 'Packing Items', 'woocommerce' ) . '</h3>';
// here goes your code and content
//custom array to list products:
$products_array = array();
$product_tally = 0;
global $post; // <=== Alway at the beginning
// Get an instance of the WC_Order Object
$order = wc_get_order( $post->ID );
// let's decide what order item types we would like to get
$types = array( 'line_item');
// defaults to line_item which allows to get products from order
foreach( $order->get_items( $types ) as $item_id => $item ) {
// order ID
$item_order_id = $item->get_order_id();
// product only and no bundle 'summary' item
if( empty( $item['woosb_ids']) && $item->is_type( 'line_item' ) ) {
// order item name (product title, name of a shipping method or coupon code)
$item_name = $item->get_name();
if ( array_key_exists($item_name, $products_array)) {
$products_array[$item_name] += $item['qty'];
} else {
$products_array[$item_name] = $item['qty'];
}
$product_tally = $product_tally + $item->get_quantity();
}
}
arsort($products_array);
echo '<div class="woocommerce_order_items" id="packing-table">
<div class="thead">
<div class="tr">
<div class="item sortable">Product</div>
<div class="quantity sortable">Qty</div>
</div>
</div>
<div class="tbody" id="order_line_items">';
//display list:
foreach ($products_array as $title => $quantity) {
echo '<div class="lineitem">
<div class="item">';
echo $title.'</div>
<div class="quantity">'.$quantity.'</div>
</div>';
}
echo '<div class="lineitem tally">
<div class="item">Tally of Items</div>
<div class="quantity">'.$product_tally.'</div>
</div>';
echo '</div>
</div>';
