Show Shipping cost in checkout page not in cart page

Question

I am using Magento 1.9.3.2.

I need customization like, Shipping cost should not show in the Cart page, but shown in the Checkout page.

Is possible to make like Shipping cost should be calculated only in checkout page, not in the Cart page even user logged in.

Answer 1

I Created a event with observer. Here is the Code:

<frontend>
    <events>
        <checkout_cart_save_before>
            <observers>
            <your_module_shipping_observer>
                <type>singleton</type>
                <class>Your_Module/observer</class>
                <method>setFreeShipping</method>
            </your_module_shipping_observer>
            </observers>
        </checkout_cart_save_before>
    </events>
</frontend>

Observer function setFreeShipping Code:

public function setFreeShipping($observer) {
    $event = $observer->getEvent();
    $cart = $event->getCart();
    $shippingaddress = $cart->getQuote()->getShippingAddress();
    $shippingaddress->setShippingMethod('')->save();
    return;
}

Answer 2

You can use the following code somewhere when cart loads:

$quote->setTotalsCollectedFlag(false);
$quote->getShippingAddress()->unsetData('cached_items_all');
$quote->getShippingAddress()->unsetData('cached_items_nominal');
$quote->getShippingAddress()->unsetData('cached_items_nonnominal');
$quote->collectTotals();

Hope this helps!
