Magento – Grand total update on billing information save in onepage checkout —Magento

grand-totalmagento-1.9

I have created a custom module to update grand total but I need to update grand total only after filling address information on one page checkout because I have to check particular postal/zip code that user added and based on that have to update grand total.Here is my config file code

   <checkout_onepage_savePayment>
        <observers>
        <magepal_mycheckout_order_observer>
        <type>singleton</type>
        <class>MagePal_MyCheckout_Model_Observer</class>
        <method>sendemail</method>
        </magepal_mycheckout_order_observer>
        </observers>
    </checkout_onepage_savePayment>

Observer.php code

$quote = $observer->getEvent()->getQuote();
    $grandTotal = $quote->getGrandTotal();
    $baseGrandTotal = $quote->getBaseGrandTotal();
    $partialPrice = $grandTotal + 10;
    $basePartialPrice = $baseGrandTotal + 10;
    $quote->setGrandTotal($partialPrice);
    $quote->setBaseGrandTotal($basePartialPrice);
    $quote->save();

I have tried several other events but when I reach to review order step,no change to grand total.

Can anybody please point me out where I did wrong ?

Any event of save of checkout_onepage_savePayment does not exit in magento.

There is an events is fire on every controller dispatch.If i guess that billing has been save it checkout/onepage/saveBilling then it dispatch event for this route is

controller_action_predispatch_checkout_onepage_saveBilling

you get data from using :

$this->getRequest()->getPost('billing', array());

checkout object from

Mage::getSingleton('checkout/type_onepage')

To calculate and process the grand total you need to follow these

$quote = Mage::getSingleton('checkout/session')->getQuote();
    $address = Mage::getSingleton('checkout/session')->getQuote()->getShippingAddress();
    $address = Mage::getSingleton('checkout/session')->getQuote()->getBillingAddress();
    $quote = $address->getQuote();
    $session= Mage::getSingleton('checkout/session');    
                $items = $session->getQuote()->getAllItems();
        //$items = $quote->getAddressItems($items);
    //echo '<pre>'; print_r($items);

    if(Excellence_Fee_Model_Fee::canApply($address)){
                 //$exist_amount = $quote->getFeeAmount();
                    // $fee = 1000;
                        //$fees = $fee * $result;
                    $balance = 1000;
                        //          $balance = $fee;

                        //$this->_setAmount($balance);
                        //$this->_setBaseAmount($balance);
                        $address->setGrandTotal($balance);

                        $address->setFeeAmount($balance);

                        $address->setBaseFeeAmount($balance);
                        $quote->setGrandTotal($balance);
                        $quote->setBaseGrandTotal($balance);
                        //echo '<pre>'; print_r($quote);
                        $quote->setFeeAmount($balance);
                        //echo '<pre>'; print_r($quote);

                        $address->setGrandTotal($address->getGrandTotal() + $address->getFeeAmount());
                        //echo '<pre>'; print_r($address);
                        $address->setBaseGrandTotal($address->getBaseGrandTotal() + $address->getBaseFeeAmount());
                        //$address->getGrandTotal();
                    //echo '<pre>'; print_r($address);
                    echo  Mage::getSingleton('checkout/cart')->getQuote()->getGrandTotal();

This is working on checkout and cart page to update the grandtotal. Hope this will help you and you find a correct solution.
