解决magento中guest页面cookie保存时间过短问题

在magento新的企业版11，有个新的功能退货（RMA），不仅能退货，还能以guest的身份查看订单的各种信息，但在IE下有个问题：cookies的保存时间太短了，如果需要使用到需要验证权限的操作，就会重定向到 sales/guest/form/ 页面。

查看关键代码，发现跳转是发生在 Mage_Sales_Helper_Guest 类中

class Mage_Sales_Helper_Guest extends Mage_Core_Helper_Dat
{
    /**
     * Cookie params
     */
    protected $_cookieName  = 'guest-view';
    protected $_lifeTime    = 600;

    /**
     * Try to load valid order by $_POST or $_COOKIE
     *
     * @return bool|null
     */
    public function loadValidOrder()
    {
        if (Mage::getSingleton('customer/session')->isLoggedIn()) {
            Mage::app()->getResponse()->setRedirect(Mage::getUrl('sales/order/history'));
            return false;
        }

        $post = Mage::app()->getRequest()->getPost();

        $type           = '';
        $incrementId    = '';
        $lastName       = '';
        $email          = '';
        $zip            = '';
        $protectCode    = '';
        $errors         = false;

        /** @var $order Mage_Sales_Model_Order */
        $order = Mage::getModel('sales/order');

        if (empty($post) && !Mage::getSingleton('core/cookie')->get($this->_cookieName)) {
            Mage::app()->getResponse()->setRedirect(Mage::getUrl('sales/guest/form'));
            return false;
        } elseif (!empty($post) && isset($post['oar_order_id']) && isset($post['oar_type']))  {
            $type           = $post['oar_type'];
            $incrementId    = $post['oar_order_id'];
            $lastName       = $post['oar_billing_lastname'];
            $email          = $post['oar_email'];
            $zip            = $post['oar_zip'];

            if (empty($incrementId) || empty($lastName) || empty($type) || (!in_array($type, array('email', 'zip')))
                || ($type == 'email' && empty($email)) || ($type == 'zip' && empty($zip))) {
                $errors = true;
            }

            if (!$errors) {
                $order->loadByIncrementId($incrementId);
            }

            if ($order->getId()) {
                $billingAddress = $order->getBillingAddress();
                if ((strtolower($lastName) != strtolower($billingAddress->getLastname()))
                    || ($type == 'email'
                        && strtolower($email) != strtolower($billingAddress->getEmail()))
                    || ($type == 'zip'
                        && (strtolower($zip) != strtolower($billingAddress->getPostcode())))
                ) {
                    $errors = true;
                }
            } else {
                $errors = true;
            }

            if (!$errors) {
                $toCookie = base64_encode($order->getProtectCode());
                Mage::getSingleton('core/cookie')->set($this->_cookieName, $toCookie, $this->_lifeTime, '/');
            }
        } elseif (Mage::getSingleton('core/cookie')->get($this->_cookieName)) {
            $fromCookie     = Mage::getSingleton('core/cookie')->get($this->_cookieName);
            $protectCode    = base64_decode($fromCookie);

            if (!empty($protectCode)) {
                $order->loadByAttribute('protect_code', $protectCode);

                Mage::getSingleton('core/cookie')->renew($this->_cookieName, $this->_lifeTime, '/');
            } else {
                $errors = true;
            }
        }

        if (!$errors && $order->getId()) {
            Mage::register('current_order', $order);
            return true;

关键是：

//如果没找到cookie的信息，就重定向到登录页面
if (empty($post) && !Mage::getSingleton('core/cookie')->get($this->_cookieName)) {
            Mage::app()->getResponse()->setRedirect(Mage::getUrl('sales/guest/form'));
            return false

设置cookie的有效期是在：

$toCookie = base64_encode($order->getProtectCode());
                Mage::getSingleton('core/cookie')->set($this->_cookieName, $toCookie, $this->_lifeTime, '/');

从上面的代码可看出，$this->_lifeTime 的值就是cookie的有效期，于是解决方法就很简单了，rewrite这个helper，把 $_lifeTime 设置为一个比较大的值就行了。
