I have a problem modifying a redirect in magento CE 1.9.2.

Let's say a customer has a configurable product in the cart, and would like to edit that product (ie. changing color or size or something).

After changing the options and clicking the 'update cart' button I want the customer to stay on the same page (ie. the edit product page). However magento always redirect back to the cart page.

I think I've found source of the problem, in CartController.php from the Checkout module:

/**

 * Update product configuration for a cart item

 */

public function updateItemOptionsAction()

{

    $cart   = $this->_getCart();

    $id = (int) $this->getRequest()->getParam('id');

    $params = $this->getRequest()->getParams();



    if (!isset($params['options'])) {

        $params['options'] = array();

    }

    try {

        if (isset($params['qty'])) {

            $filter = new Zend_Filter_LocalizedToNormalized(

                array('locale' => Mage::app()->getLocale()->getLocaleCode())

            );

            $params['qty'] = $filter->filter($params['qty']);

        }



        $quoteItem = $cart->getQuote()->getItemById($id);

        if (!$quoteItem) {

            Mage::throwException($this->__('Quote item is not found.'));

        }



        $item = $cart->updateItem($id, new Varien_Object($params));

        if (is_string($item)) {

            Mage::throwException($item);

        }

        if ($item->getHasError()) {

            Mage::throwException($item->getMessage());

        }



        $related = $this->getRequest()->getParam('related_product');

        if (!empty($related)) {

            $cart->addProductsByIds(explode(',', $related));

        }



        $cart->save();



        $this->_getSession()->setCartWasUpdated(true);



        Mage::dispatchEvent('checkout_cart_update_item_complete',

            array('item' => $item, 'request' => $this->getRequest(), 'response' => $this->getResponse())

        );

        if (!$this->_getSession()->getNoCartRedirect(true)) {

            if (!$cart->getQuote()->getHasError()) {

                $message = $this->__('%s was updated in your shopping cart.', Mage::helper('core')->escapeHtml($item->getProduct()->getName()));

                $this->_getSession()->addSuccess($message);

            }

            $this->_goBack();

        }

    } catch (Mage_Core_Exception $e) {

        if ($this->_getSession()->getUseNotice(true)) {

            $this->_getSession()->addNotice($e->getMessage());

        } else {

            $messages = array_unique(explode("n", $e->getMessage()));

            foreach ($messages as $message) {

                $this->_getSession()->addError($message);

            }

        }



        $url = $this->_getSession()->getRedirectUrl(true);

        if ($url) {

            $this->getResponse()->setRedirect($url);

        } else {

            $this->_redirectReferer(Mage::helper('checkout/cart')->getCartUrl());

        }

    } catch (Exception $e) {

        $this->_getSession()->addException($e, $this->__('Cannot update the item.'));

        Mage::logException($e);

        $this->_goBack();

    }

    $this->_redirect('*/*');

}

The call to $this->_goBack() in the end of the try-block seems to set the redirect URL correctly by looking at settings and a 'return_url' parameter (and I've verified that the code gets this far). But, as you can see, the last line always sets a redirect to */* no matter what. Just adding a return statement after the _goBack() call fixes the problem but I rather do this without modifying the core files.

Any ideas how I can solve this problem?

If you want the customer to say on the update page you could

1. Use Ajax to post the changes to the server.




2. Add a return_url parameter to your post action (with the current url see protected function _goBack())




3. Change the global behavior for adding and updatig product in System -> Configuration -> Sales tab -> Checkout and then in the Shopping Cart tab you set the After Adding a Product Redirect to Shopping Cart




4. Rewrite the controller using a custom module
