How to get the order ID in the order-received and view-order page?

For my Fancy Product Designer plugin I need to get the order ID in the order-received page and view-order page. Woocommerce offers a filter hook to get the ordered item link: woocommerce_order_item_name, which is currently not documented in the filter hooks reference. I found it when I browsed through the woocommerce source code. Its located in the order-details.php template. For older version than 2.1 it was woocommerce_order_table_product_title.

Via this filter hook you can change the item link and receive an array that represents the item. The array contains following values:

$reserved_item_meta_keys = array(
	'name',
	'type',
	'item_meta',
	'qty',
	'tax_class',
	'product_id',
	'variation_id',
	'line_subtotal',
	'line_total',
	'line_tax',
	'line_subtotal_tax'
);

Let’s see how it looks like when using the filter hook:

add_filter( 'woocommerce_order_item_name', 'add_edit_link_to_order_item' , 10, 2 );
function add_edit_link_to_order_item( $link, $item ) {
  return $link;
}

For my Fancy Product Designer plugin I need to get the current order ID, in older version it was very easy, because it was appended as GET parameter in the URL, so I could receive it via a simple $_GET request. It’s still available as GET parameter, when default permalinks are used. But for custom permalinks, it’s now shown as path in the URL, e.g. my-account/view-order/398/. I was browsing through the source code of woocommerce and was not thinking that it will be such a tough task to get the order ID, actually I thought woocommerce offers a simple solution to get the order ID of an item, but I could not find any simple solution, so I created this little dirty snippet:

add_filter( 'woocommerce_order_item_name', 'add_edit_link_to_order_item' , 10, 2 );
function add_edit_link_to_order_item( $link, $item ) {

//check if on view-order page and get parameter is available
if(isset($_GET['view-order'])) {
    $order_id = $_GET['view-order'];
}
//check if on view order-received page and get parameter is available
else if(isset($_GET['order-received'])) {
    $order_id = $_GET['order-received'];
}
//no more get parameters in the url
else {
    $url = $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];
    $template_name = strpos($url,'/order-received/') === false ? '/view-order/' : '/order-received/';
    if (strpos($url,$template_name) !== false) {
        $start = strpos($url,$template_name);
        $first_part = substr($url, $start+strlen($template_name));
        $order_id = substr($first_part, 0, strpos($first_part, '/'));
    }
}
//yes, I can retrieve the order via the order id
$order = new WC_Order($order_id);

return $link; 
}

First of all…if anyone has a simpler solution, please let me know via the comments.
