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

[php]
view plain
copy

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：

[php]
view plain
copy

//如果没找到cookie的信息，就重定向到登录页面
f (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：

[php]
view plain
copy

$toCookie = base64_encode($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。
