如何在magento中检索数组值

Question

例如，我需要从此会话中检索值。我应该怎么做 ？确切地说，我需要获得“ customer_log_id ”。

Answer 1

$a['core']['visitor_data']['customer_log_id']

Answer 2

您似乎正在尝试从$_SESSION数组中检索信息。有两种方法可以做到这一点。正如另一张海报建议的那样，你可以简单地将它从$_SESSION超级全球中删除：

$logId = $_SESSION['core']['visitor_data']['customer_log_id'];

然而，这是一个避免Magento框架的黑客攻击。更好的选择（从“正确性”的角度来看）是使用Magento的会话管理。所以，相反，我们有：

// we could also skip a step and just use Mage::getSingleton("core/session")->getVisitorData(), 
// but I wanted to add the datatypes for your reference
$session =  Mage::getSingleton("core/session"); // Mage_Core_Model_Session
$customerData = $session->getVisitorData(); // array
$logId = $customerData['customer_log_id']; // int

希望有所帮助！
