Rechnungsnummer in der Bestellübersicht – Germanized

Ein Kunde möchte die Rechnungsnummer in der Admin Spalte sehen. Das klappt leider nicht von Haus aus mit WooCommerce Germanized* Plugin. Aber mit diesem kleinen Snippet ist das ohne Probleme möglich. Das Snippet in die function.php schreiben oder via Snippet Tool.

// Add custom column to order table
add_filter( 'manage_shop_order_posts_columns', 'add_invoice_number_column_to_orders_table', 20 );
function add_invoice_number_column_to_orders_table( $columns ) {
    // Find the position of the "Order Number" column
    $order_number_column = array_search( 'order_number', array_keys( $columns ) );

    // Insert "Invoice Number" column after "Order Number" column
    $new_columns = array_slice( $columns, 0, $order_number_column + 1, true ) +
        array( 'invoice_number' => __('Rechnungsnummer', 'your-text-domain') ) +
        array_slice( $columns, $order_number_column + 1, null, true );

    return $new_columns;
}

// Display custom column data in order table
add_action( 'manage_shop_order_posts_custom_column', 'display_invoice_number_in_orders_table', 99 );
function display_invoice_number_in_orders_table( $column ) {
    global $post;

    // Check if Germanized is active
    if ( class_exists( 'WC_GZDP_Invoice' ) && $column === 'invoice_number' ) {
        // Get the order ID
        $order_id = $post->ID;
        // Get the invoices for the order
        $invoices = wc_gzdp_get_invoices_by_order( wc_get_order( $order_id ), 'simple' );
        // Check if there is at least one invoice
        //var_dump($invoices);
        if ( count( $invoices ) > 0 ) {
            // Get the formatted number of the first invoice
            //$invoices[0]->document->formatted_number
            foreach( $invoices as $invoice ) {
            echo ($invoice->formatted_number);
            }

        } else {
            echo "N/A";
        }
    }
}
