I am using an observer to check the shipping information provided by the customer during onepage checkout. By observing the event
checkout_controller_onepage_save_shipping_method I want to redirect the customer back to the shipping step to re-enter their information.
Following the conversation on this page, What is the correct way to stop a checkout from an event observer in Magento?, I have everything set up, but I do not want to redirect them to cart, just the shipping step.
Can I make the code simply refresh the page?
Mage::app()->getResponse()->setRedirect(Mage::getUrl('checkout/onepage')); does not work.
