WooCommerce 2.2 - Register new order statuses.

functions.php

<?php

// My new order statuses.
function register_my_new_order_statuses() {
	register_post_status( 'wc-status-name', array(
		'label'                     => _x( 'Status Name', 'Order status', 'textdomain' ),
		'public'                    => true,
		'exclude_from_search'       => false,
		'show_in_admin_all_list'    => true,
		'show_in_admin_status_list' => true,
		'label_count'               => _n_noop( 'Status name <span class="count">(%s)</span>', 'Status names <span class="count">(%s)</span>', 'textdomain' )
	) );
}

add_action( 'init', 'register_my_new_order_statuses' );

// Register in wc_order_statuses.
function my_new_wc_order_statuses( $order_statuses ) {
	$order_statuses['wc-status-name'] = _x( 'Status Name', 'Order status', 'textdomain' );

	return $order_statuses;
}

add_filter( 'wc_order_statuses', 'my_new_wc_order_statuses' );

I want to add several statuses, I've tried different ways but it only adds one. What do I need to do to add multiple statuses? Thanks in advance.

As this example uses the naming "statuses", there might be a possibility to add multiple statuses.
But as I haven't figured it out myself, I just copied this piece of code for each additional status.

Hey, thanks for the snippet. I've successfully added my custom status "Quote". I'm just having trouble having it set to a pending or onhold wc status so i can edit it at anytime. At the moment it's down as paid by default and i can't seem to edit the order unless i refund first.
Any ideas?

I tried to adopt it a bit to make it use multiple statuses given by the admin settings.

    private function __construct() {
        add_action('init', array($this, 'register_additional_order_statuses'),10);
        add_filter('wc_order_statuses', array($this, 'add_additional_statuses_to_order_statuses'));
    }

    public function register_additional_order_statuses() {
        $additional_statuses_raw = trim(get_option('additional_statuses'));
        $add_statuses = explode("\n", $additional_statuses_raw);
        $add_statuses = array_filter($add_statuses, 'trim');
        foreach ($add_statuses as $add_status) {
            $wcName = "wc-" . implode("-", explode(" ", $add_status));
            register_post_status($wcName, array(
                'label' => _x($add_status, 'Order status', 'textdomain'),
                'public' => true,
                'exclude_from_search' => false,
                'show_in_admin_all_list' => true,
                'show_in_admin_status_list' => true,
                'label_count' => _n_noop($add_status . '<span class="count">(%s)</span>', $add_status . ' <span class="count">(%s)</span>', 'woocommerce' )
            ));
        }
    }

    public function add_additional_statuses_to_order_statuses($order_statuses) {
        $additional_statuses_raw = trim(get_option('additional_statuses'));
        $add_statuses = explode("\n", $additional_statuses_raw);
        $add_statuses = array_filter($add_statuses, 'trim');
        foreach ($add_statuses as $add_status) {
            $wcName = "wc-" . implode("-", explode(" ", $add_status));
            $order_statuses[$wcName] = _x($add_status, 'Order status', 'textdomain');
        }
        return $order_statuses;
    }

However I am struggling with the fact that now, when I look at my order field, none orders are displayed.
The "All" tab displays that there are 4, but for some reason they aren't displayed.
I put a screenshot here:

Any thoughts?

I just want to change the name of the existing orders. Didn't find how to do that anywhere.
I used this code and it changed the names in the main list, but in the actions dropdown and the filter in orders list dons't change.

Any thoughts? Thanks very much!

function wc_get_order_statuses() {
$order_statuses = array(
'wc-pending' => _x( '1 - Em orçamento', 'Order status', 'woocommerce' ),
'wc-processing' => _x( '2 - Pedido em atendimento', 'Order status', 'woocommerce' ),
'wc-on-hold' => _x( '3 - Pedido enviado', 'Order status', 'woocommerce' ),
'wc-completed' => _x( '4 - Pedido realizado', 'Order status', 'woocommerce' ),
'wc-cancelled' => _x( 'Cancelado', 'Order status', 'woocommerce' ),
'wc-refunded' => _x( 'Reembolso ao cliente', 'Order status', 'woocommerce' ),
'wc-failed' => _x( 'Falhou', 'Order status', 'woocommerce' ),
);
return apply_filters( 'wc_order_statuses', $order_statuses );
}

How can I also send the email with the new order status ? Just like the woocommerce sends an email to the customer when change the order status to "Completed".

I also have a similar issue like @jwad93. I want to send emails as soon as the status of product gets changed.
But in Woocommerce>Settings>Email only predefined options are present. For every status we hava a file separately stored in woocommerce>templates>emails.

So do I need to create a new file for every custom order status??
