Include Text Box for Gift Message in Checkout

-- HikaShop version -- : 2.3.4
-- Joomla version -- : 3.3.6

Hello, there.

Good evening!

During the checkout process, when the "Use the same address as for billing" checkbox is ticked (for the Shipping Address), I will like to display a textbox for the user to write a message.

I understand that this will be a two-step process:
a) create a custom text field for the order table (which I have done)
b) display the custom field when the checkbox is ticked (which is what I need help in)

Please could you tell me which file to edit and the example code to include?

Thanks.

Take care!

Hello,
To do it you'll have to edit the "Address" file of the "Checkout" view of your front-end template use some JavaScript code, you'll also have to edit these lines :

<label for="same_address">
	<input class="hikashop_checkout_shipping_same_address inputbox" <?php echo $checked; ?>type="checkbox" id="same_address" name="same_address" value="yes" alt="Same address" onclick="<?php echo $onclick; ?>" />
	<?php echo JText::_('SAME_AS_BILLING');?>
</label>
