Add shipping charges before login or entering customer details in onepage review block

Question

I am using onepage checkout extension, I wish to add shipping charges of products to be added in review block before login and entering customer information. Let us take an example, product having a cost of Rs.430 and its shipping charge is Rs.80(set from backend for every product), then I just want to show 430+80 in review block, without entering any details and before login at onepage checkout page.Kindly refer to the attached screenshot for the same.

Yes, you can do this by using an event observer, you can use the "sales_quote_collect_totals_before" event to add your shipping method like "flatrate" and set the necessary values and display on review page, please find the code below and use it as per your requirement :)

Event:

<sales_quote_collect_totals_before>
     <observers>
         <set_shipping_cartpage>
              <type>singleton</type>
              <class>modulename/observer</class>
              <method>yourmethodname</method>
              </set_shipping_cartpage>
         </observers>
</sales_quote_collect_totals_before>

Observer:

$country = 'US'; //your country code
$postcode = '';
$city = '';
$regionId = '';
$region = '';
$code = 'modulename_standard';

$quote = $observer->getEvent()->getQuote();

if (!$quote->getId()) return;

$shippingMethod = $quote->getShippingAddress()->getShippingMethod();

if ($shippingMethod) return;

$shippingAddress = $quote->getShippingAddress();

$model = Mage::getModel("modulename/carrier_method_standard");

$subTotal = $quote->getSubtotal();

$price = 0.00; // Add your shipping price

$shippingAddress
    ->setCountryId($country)
    ->setRegionId($regionId)
    ->setPostcode($postcode)
    ->setShippingMethod($code)
    ->setShippingAmount($price)
    ->setCollectShippingRates(true);

$shippingAddress->save();

$quote->save();

After that you need to override the collectotals to add you shipping like I mentioned above "carrier_method_standard" and on checkout page override the progress block to add your functions to display your before login shipping method. Hope that will help you to integrate the same :)

Accept it if that helps.
