Magento Checkout – Associate Guest Checkout with Account if Email Matches

checkoutcustomeree-1.13.1.0email

In the admin panel under the menu item Customers > Manage Customers. When you click on a customer it shows all their customer information.

The problem is if I checkout as a guest and use the same email i use when i'm logged in the record does not get stored in my recent orders. Is this functionality standard? Is there a way to associate the emails so even if they checkout as a guest it still gets recorded in the customer information > recent orders section?

I've looked through the configuration settings for customer configuration and checkout but to no avail.

It only shows under Sales > Orders.

Are you allowed to store information if they're a guest?

By default when a customer check out as a register user magento will store the customer info and link the customer to existing order using: 

Table : sales_flat_order
   - customer_id        : numeric customer id
   - customer_is_guest  : bool - add clickable link in sales order admin

Therefore you could create a custom module. Then using an observer you could

  1. Check if the customer is checking out as guest
  2. If there is a existing customer with the same email
  3. Update the order accordingly.

Please note this method may assign the order to wrong user if someone existing customer mistype there email

In config.xml

...
<events>
  <sales_order_place_before>
    <observers>
      <sales_order_place_after_observer>
        <type>singleton</type>
        <class>convertcustomer/observer</class>
        <method>checkCustomerRecord</method>
      </sales_order_place_after_observer>
    </observers>
  </sales_order_place_before>     
</events>
...

In observer.php

Class MagePal_Model_ConvertCustomer_Observer{
    function checkCustomerRecord($observer){
        $order = $observer->getOrder();

        // if guest
        if(!$order->getCustomerId()){
            $storeId = $order->getStoreId()
            $websiteId = Mage::getModel('core/store')->load($storeId)->getWebsiteId();

            $customer = Mage::getModel("customer/customer"); 
            $customer->setWebsiteId($websiteId); 
            $customer->loadByEmail($email);

            //if email found
            if($customer->getId()){
                $order->setCustomerId($customer->getId());
                $order->setCustomerIsGuest(0);
            }
        }
    }
