Redirect Magento to checkout onepage after adding item to cart

Question

How can I redirect the user after it adds one item to the cart?
lets say I want him to choose one item and go to the checkout/onepage, how can I do that?

Answer 1

You could create an observer listening for the checkout_cart_add_product_complete event and in there you could do something like the following

  public function addToCartComplete(Varien_Event_Observer $observer) {
    // Send the user to the Item added page
    $response = $observer->getResponse();
    $request = $observer->getRequest();
    $response->setRedirect(Mage::getUrl('checkout/onepage'));
    Mage::getSingleton('checkout/session')->setNoCartRedirect(true);
}

Your config would look something like this

 
    
    
      
        
          singleton
          packagename_modulename/observer
          addToCartComplete
