How to Remove Product from cart on checkout page or by coding in magento

From magento cart you can delete product by clicking on delete button from cart page , but if you wish to delete any cart item in checkout page or by coding then you have write


$session= Mage::getSingleton('checkout/session');

$quote = $session->getQuote();



$cart = Mage::getModel('checkout/cart');

$cartItems = $cart->getItems();

foreach ($cartItems as $item)

{

    $quote->removeItem($item->getId())->save();

}



By writing the above code your all cart item will be delete.If you wish to delete a particular product from the cart session then instead of writing $item->getId() pass your Id of the product.

e.g: -

foreach ($cartItems as $item)

{

    if($item->getId()== 2)

    {

        $quote->removeItem($item->getId())->save();

    }

}
