How to hide the credit card charging amount after choosing COD in onePage checkout

Question

I've enabled the COD options in a magento ce 1.9.2.4 store. In the onePage checkout if the user choose the COD option it's still visible in the Order Review a table row telling Your credit card will be charged for and giving the final value in the base currency. For me I want to hide this row ONLY if the user chosen the COD.

is there's a direct option for that? code hints? and to tell I've thought about a simple jquery solution but IDK is it okay to do so or there's a magento recommended solution? This image taken from fresh installation:

Answer 1

You can rewrite Mage_Checkout_Block_Cart_Totals::needDisplayBaseGrandtotal() function to achieve this with below code.

public function needDisplayBaseGrandtotal()
{
    $quote  = $this->getQuote();
    $hideForPayment = 'cashondelivery'; // Your Payment method code for which you want to hide message
    if ($quote->getBaseCurrencyCode() != $quote->getQuoteCurrencyCode() && $quote->getPayment()->getMethod() != $hideForPayment) {
        return true;
    }
    return false;
}

Answer 2

Did your order review reload after you change the payment method ?

Or you can check if there is JavaScript conflict/error from your browser

Check this file, if you want to hide the code is up to you.

app\design\frontend\base\default\template\checkout\onepage\review\totals.phtml

or you can try this one :
