Magento – Changing cart image based on cart item

You can write an observer listen to the post_dispatch event

'controller_action_postdispatch_wishlist_index_cart'

and change the response to a redirect to the wishlist.

So create a new module/extension and add the following to your config.xml:

<global>
    ...
    <events>
        ...
        <controller_action_postdispatch_wishlist_index_cart>
            <observers>
                <yourcompany_yourmodule>
                    <type>singleton</type>
                    <class>YourCompany_YourModule_Model_Observer</class>
                    <method>controllerActionPostdispatchWishlistIndexCart</method>
                </yourcompany_yourmodule>
            </observers>
        </controller_action_postdispatch_wishlist_index_cart>
    </events>
</global>

Then in your Observer.php add the following method:

public function controllerActionPostdispatchWishlistIndexCart()
{
    Mage::app()->getFrontController()->getResponse()->setRedirect(Mage::app()->getRequest()->getServer('HTTP_REFERER'));
}

That's it. Every time you will try to add something from your wishlist to your cart you will be redirected back to wishlist.

Refresh your session, after adding product to cart. This is dirty solution, but in my case it works.

$session = Mage::getSingleton('checkout/session');
$quoteId = $session->getQuote()->getId();
$session->clear();
$session->setQuoteId($quoteId);
