redirect /checkout/cart page

Question

I've combined my checkout page (OneStepCheckout) and cart page. The /checkout/cart (the cart page) is still accessible, and I wouldn't want my customer to accidentally access that page (reviewing your cart twice would be quite confusing).

Is there anyway I can redirect this page with magento to /checkout ?

Answer 1

In this case you need 301 redirection from checkout/cart to your checkout page

  Mage::app()->getResponse()
        ->setRedirect($someUrl, 301)
        ->sendResponse();

use event controller_action_predispatch_checkout_cart_index fire an observer

<frontend>
    <events>
        <controller_action_predispatch_checkout_cart_index>
            <observers>
                <customRedir>
                    <class>YourModulePrefix/observer</class>
                    <method>customRedir</method>
                </customRedir>
            </observers>
        </controller_action_predispatch_checkout_cart_index>
        </events>
</frontend>

Observer code:

<?php
class MymoduleNameSpace_ModuleName_Model_Observer{

    public function customRedir($oberver){
          Mage::app()->getResponse()
        ->setRedirect($someUrl, 301)
        ->sendResponse();
        die();

    }
}
