Add price calculation in checkout page

[toalka]

Hi,

 

I need to add radio which change, will lead to the change in total price.

 

I add this code in order-detail.tpl:

<tr class="cart_disc">
    <td colspan="1" class="text-right">
        <input id="discount_option_1_0" class="discount_option_radio" type="radio" name="discount_option" data-key="1" data-id_address="1" value="1" checked="checked">
    </td>
    <td colspan="2" class="text-right">Pago a 30 dias mediante transferencia. Dto -2%</td>
    <td colspan="2" class="price" id="disc1">-0,00 €</td>
</tr>

<tr class="cart_disc">
    <td colspan="1" class="text-right">
        <input id="discount_option_2_1" class="discount_option_radio" type="radio" name="discount_option" data-key="2" data-id_address="2" value="2">
    </td>
    <td colspan="2" class="text-right">Pronto pago antes de la salida de la mercaderia Dto. -5%</td>
    <td colspan="2" class="price" id="disc2">-0,00 €</td>
</tr>

<tr class="cart_disc">
    <td colspan="1" class="text-right">
        <input id="discount_option_3_2" class="discount_option_radio" type="radio" name="discount_option" data-key="3" data-id_address="3" value="3">
    </td>
    <td colspan="2" class="text-right">Pago mediante Tarjeta de credito. Dto. -2%</td>
    <td colspan="2" class="price" id="disc3">-0,00 €</td>
</tr>

<tr class="cart_disc">
    <td colspan="1" class="text-right">
        <input id="discount_option_4_3" class="discount_option_radio" type="radio" name="discount_option" data-key="4" data-id_address="4" value="4">
    </td>
    <td colspan="2" class="text-right">Pago a mas de 30 dias, NO aplicable ningun Dto.</td>
    <td colspan="2" class="price" id="disc4">0,00 €</td>
</tr>

How to connect it with Order.php to make it works?

 

Thanks!
