Universal method

config.xml

<events>
    <sales_quote_save_after>
        <observers>
            <module_model_observer>
                <type>singleton</type>
                <class>module/observer</class>
                <method>salesQuoteSaveAfter</method>
            </module_model_observer>
        </observers>
    </sales_quote_save_after>
</events>

Observer.php

public function salesQuoteSaveAfter($observer)
{
    /** @var Mage_Sales_Model_Quote $quote */
    $quote = $observer->getEvent()->getQuote();
    if($quote->getItemsCount() == 0) {
        // your code
    }
}

i recently implemented this in a custom module.

controller_action_predispatch_checkout_cart_updatePost

this event get calls exactly when pressed clear cart.

in the observer you can check if the method was called for empty cart:

$post = Mage::app()->getRequest()->getPost('update_cart_action'); // get value if ($post == 'empty_cart') { // perform logic $quote = Mage::helper('checkout/cart')->getQuote(); //quote $allQuoteItems = $quote->getAllItems(); // quote items // do code }

Hope it helps.

There is no event in 1.7.0.2

// app/code/core/Mage/Checkout/controllers/CartController.php:389
Mage_Checkout_CartController::updatePostAction()

// app/code/core/Mage/Checkout/controllers/CartController.php:441
Mage_Checkout_CartController::_emptyShoppingCart()

// app/code/core/Mage/Checkout/Model/Cart.php:489
Mage_Checkout_Model_Cart::truncate()

// app/code/core/Mage/Sales/Model/Quote.php:837
Mage_Sales_Model_Quote::removeAllItems()

You can listen on checkout_cart_save_before and check wether the cart is empty and your setting is set, if yes, remove it.
