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
