Magento how to checkout one product from the customer dashboard

Question

I have a product whose price is 100$ and its a virtual product. I want to show that product in customer dashboard as a button and if customer clicks the button then he will be going for a checkout process of $100. I want the product should go to checkout from the customer dashboard.

Answer 1

You can override a CartController and add a new action named addvirtualAction(). Copy all code from default addAction() to addvirtualAction() and replace following block:

if (!$cart->getQuote()->getHasError()) {
    $message = $this->__('%s was added to your shopping cart.', Mage::helper('core')->escapeHtml($product->getName()));
    $this->_getSession()->addSuccess($message);
}

WITH :

if (!$cart->getQuote()->getHasError()) {
    /* REDIRECT TO CHECKOUT FROM HERE */
}

Now you have to set that PRODUCT BUTTON url as

$this->getUrl("checkout/cart/addvirtual", array("product"=> $product->getId(), "form_key" => Mage::getSingleton('core/session')->getFormKey() ))

this will generate url like: http://127.0.0.1/mage1921/checkout/cart/addvirtual/product/1/form_key/nyhjZWTTLQ3pcj2F/

UPDATE: For multiple quantities use this code:

$this->getUrl("checkout/cart/addvirtual", array("product"=> $product->getId(), "qty"=> NO_OF_QUANTITY, "form_key" => Mage::getSingleton('core/session')->getFormKey() ))

That's it...

By another way, you can use observer that dispatches after product is added to cart for redirecting to CHECKOUT page
