Magento订单状态 是定义在Magento代码文件app\code\core\Mage\Sales\Model\Order.php中定义了订单的状态常量：

/**
 * Order model
 *
 * Supported events:
 *  sales_order_load_after
 *  sales_order_save_before
 *  sales_order_save_after
 *  sales_order_delete_before
 *  sales_order_delete_after
 *
 * @author Magento Core Team <core@magentocommerce.com>
 */
class Mage_Sales_Model_Order extends Mage_Sales_Model_Abstract
{

    /**
     * Order states
     */
    const STATE_NEW             = 'new';
    const STATE_PENDING_PAYMENT = 'pending_payment';
    const STATE_PROCESSING      = 'processing';
    const STATE_COMPLETE        = 'complete';
    const STATE_CLOSED          = 'closed';
    const STATE_CANCELED        = 'canceled';
    const STATE_HOLDED          = 'holded';
    const STATE_PAYMENT_REVIEW  = 'payment_review'; // added magento 1.4

    /**
     * Order flags
     */
    const ACTION_FLAG_CANCEL    = 'cancel';
    const ACTION_FLAG_HOLD      = 'hold';
    const ACTION_FLAG_UNHOLD    = 'unhold';
    const ACTION_FLAG_EDIT      = 'edit';
    const ACTION_FLAG_CREDITMEMO= 'creditmemo';
    const ACTION_FLAG_INVOICE   = 'invoice';
    const ACTION_FLAG_REORDER   = 'reorder';
    const ACTION_FLAG_SHIP      = 'ship';
    const ACTION_FLAG_COMMENT   = 'comment';

    // ...
}
</core@magentocommerce.com>

其中，pending_payment, payment_review 是支付（Paypal, Amazon Pay）过程中引入的订单状态。

<?php

require_once('app/Mage.php');
umask(0);
Mage::app('default');

$order = Mage::getModel('sales/order');
$order->loadByIncrementId(100000001);  // 100000001为订单编号

// 获取订单状态
$status = $order->getStatus();
$state  = $order->getState();

echo $status;
echo "\r\n";
echo $state;

// 设置订单状态
$order->setStatus(Mage_Sales_Model_Order::STATE_PROCESSING);
$order->save();
