I found this answer on stackoverflow...

require_once 'app/Mage.php';


umask(0);

Mage::app('default');

Mage::getSingleton('core/session', array('name' => 'frontend'));

$sessionCustomer = Mage::getSingleton("customer/session");

if($sessionCustomer->isLoggedIn()) {
  echo "Logged";
} else {
   echo "Not Logged";
}

Answer 2

The way that I have achieved this in the past is to rely on the Magento cron and run this every X interval.

The way to check if a customer is logged in or not is to look at the log_customer table within Magento. There are 2 columns login_at logout_at if there is a timestamp for logout_at then you know that the customer has logged out and it is safe to trigger some action.

Without looking at the code again I cant remember if there is a model you can use to get access to this data or if I had to rely on SQL to access the data.

However looking at this table should provide you with the information you require.

One consideration is that the log_* tables can be disabled so depending on the store you might not have access to this data.

Answer 3

If the customer physically clicks on the logout button, then you could observe the following event: controller_action_predispatch_customer_account_logout

If the customer closes the browser window, you could add some javascript that detects this which can send an XHR request notifying Magento of the window being closed.

If the user closes the browser, you last bet would be to look at log tables.

The better way to check for abandoned carts is to check x days against stale quotes.
