如何在根索引文件中获取magento客户会话值以切换商店视图

Question

我为在magento 1.9.2下运行的magento网站创建了2个商店视图，我需要为两个网站使用相同的域名。我需要的是当客户登录后，我需要将商店视图更改为第二个视图。我需要在根目录的index.php文件中检查客户会话。但是，当我按照以下对index.php的更改进行操作时，我最终会出错，

$store_id = 1;
//Check customer session here 
if(Mage::getSingleton('customer/session')->isLoggedIn()){ // Error occurs here

    $customer       = Mage::getModel('customer/session')->getCustomer();            
    $customerId     = $customer->getId(); 
    // $storeid  get logged in customer storeid may from customer custom attribute value added on admin edit form
    // $store_id value get changed here
}



Mage::app()->setCurrentStore($store_id);
umask(0);
$mageRunCode = isset($_SERVER['MAGE_RUN_CODE']) ? $_SERVER['MAGE_RUN_CODE'] : '';
$mageRunType = isset($_SERVER['MAGE_RUN_TYPE']) ? $_SERVER['MAGE_RUN_TYPE'] : 'store';

if($store_id == 2)
$mageRunCode = 'mysecondshop';

Mage::run($mageRunCode, $mageRunType);

[当我检查问题时，发现我们不能在Mage :: run之前使用Mage :: getSingleton，但是对于当前在商店之间进行切换的情况，我需要在运行Mage之前登录用户详细信息，有什么办法达到我的要求。

在magento中，除非初始化了Mage :: run，否则无法检查会话数据。我们需要做一些临时存储（例如cookie）来实现此目的。希望下面的步骤能使它起作用。

[使用观察者创建自定义模块，以保存，清除和检查Cookie。您的config.xml文件在下面给出

<!--------------------------------------------------------------------->
<customer_login>
  <observers>
    <Company_Modulename_model_customer_login>
      <class>Company_Modulename_Model_Observer</class>
      <method>afterCustomerLoggedIn</method>
    </Company_Modulename_model_customer_login>
  </observers>
</customer_login>
<customer_logout>
  <observers>
    <Company_Modulename_model_customer_logout>
      <class>Company_Modulename_Model_Observer</class>
      <method>afterCustomerLoggedOut</method>
    </Company_Modulename_model_customer_logout>
  </observers>
</customer_logout>
<controller_action_layout_load_before>
  <observers>
    <Company_Modulename_model_layoutload_observer>
      <class>Company_Modulename_Model_Observer</class>
      <method>beforeLoadLayout</method>
    </Company_Modulename_model_layoutload_observer>
  </observers>
</controller_action_layout_load_before>
<!--------------------------------------------------------------------->

观察者的实现在下面给出

public function afterCustomerLoggedIn(Varien_Event_Observer $observer)
{
    $customer = $observer->getCustomer();
    $cid      = $customer->getid();
    $webId    = $customer->getWebsiteId();
    Mage::getModel('core/cookie')->set('_storeuid',$cid, 60*60*24*1);  // Create cookie
    Mage::getModel('core/cookie')->set('_storeid',$webId, 60*60*24*1); // Create cookie

}


public function afterCustomerLoggedOut(Varien_Event_Observer $observer)
{
    $customer = $observer->getCustomer();
    $cid      = $customer->getid();
    $webId    = $customer->getWebsiteId();  
    Mage::getModel('core/cookie')->set('_storeuid','0', 1); // Clear cookie
    Mage::getModel('core/cookie')->set('_storeid','0', 1);  // Clear cookie

}

渲染页面之前

public function beforeLoadLayout(Varien_Event_Observer $observer)
{


    $cookieValue = Mage::getModel('core/cookie')->get('_storeuid');
    $baseurl = Mage::getBaseUrl();

    if(Mage::getSingleton('customer/session')->isLoggedIn()){ // For more security , if someone change the cookie value


        $customer = Mage::getModel('customer/session')->getCustomer();          
        $webId    = $customer->getWebsiteId();
        $cid      = $customer->getId();

        if( $cookieValue != $cid ){

                Mage::getModel('core/cookie')->set('_storeuid',$cid, 60*60*24*1);
                Mage::getModel('core/cookie')->set('_storeid',$webId, 60*60*24*1);
                header("Location: ".$baseurl); exit;

       }
    }else{

        if( (isset($cookieValue)) && ($cookieValue > 0)  ){ // Clear cookie if session is cleared

            Mage::getModel('core/cookie')->set('_storeuid','0', 1);
            Mage::getModel('core/cookie')->set('_storeid','0', 1);
            header("Location: ".$baseurl); exit;

        }

    }
}

最后在index.php中，您可以检查cookie以切换已登录客户的商店价值

$store_id = 1;
if( (isset($_COOKIE['_storeur'])) && ($_COOKIE['_storeur'] > 0)  ){
    $store_id = $_COOKIE['_storeur'];
}

$mageRunCode = isset($_SERVER['MAGE_RUN_CODE']) ? $_SERVER['MAGE_RUN_CODE'] : '';
$mageRunType = isset($_SERVER['MAGE_RUN_TYPE']) ? $_SERVER['MAGE_RUN_TYPE'] : 'store';

if($store_id == 2 ) $mageRunCode = 'store2';
if($store_id == 3 ) $mageRunCode = 'store3';
//....................
Mage::run($mageRunCode, $mageRunType);
