Try this to create a custom order status called "Invoiced". Add this to your theme's functions.php
// New order status AFTER woo 2.2
add_action( 'init', 'register_my_new_order_statuses' );
function register_my_new_order_statuses() {
register_post_status( 'wc-invoiced', array(
'label' => _x( 'Invoiced', 'Order status', 'woocommerce' ),
'public' => true,
'exclude_from_search' => false,
'show_in_admin_all_list' => true,
'show_in_admin_status_list' => true,
'label_count' => _n_noop( 'Invoiced <span class="count">(%s)</span>', 'Invoiced<span class="count">(%s)</span>', 'woocommerce' )
) );
}
add_filter( 'wc_order_statuses', 'my_new_wc_order_statuses' );
// Register in wc_order_statuses.
function my_new_wc_order_statuses( $order_statuses ) {
$order_statuses['wc-invoiced'] = _x( 'Invoiced', 'Order status', 'woocommerce' );
return $order_statuses;
}
Use javascript to add your new status to the Bulk-edit admin drop-down. Add a function to the admin footer action. It will appear like this
function custom_bulk_admin_footer() {
global $post_type;
if ( $post_type == 'shop_order' ) {
?>
<script type="text/javascript">
jQuery(document).ready(function() {
jQuery('<option>').val('mark_invoiced').text('<?php _e( 'Mark invoiced', 'textdomain' ); ?>').appendTo("select[name='action']");
jQuery('<option>').val('mark_invoiced').text('<?php _e( 'Mark invoiced', 'textdomain' ); ?>').appendTo("select[name='action2']");
});
</script>
<?php
}
}
As you noticed the action is added two times that's coz there are one bulk action at the top and second at the bottom of the order list.
