Adding new checkbox on order step (like recycled packaging)

[tomi]

Hi i try to add extra checkbox on order process with question for buyer.

I try to do someting like that - http://www.prestashop.com/forums/viewthread/13859/P0/configuring___using_prestashop/solved_adding_new_fields_to_new_account

I've changed
Order.php
order-address.tpl
AdminOrders.php
order.php

and database

but system dont read extra checkbox

If I change Order.php on

/** @var boolean Customer is ok for a question*/
   public        $extracheckbox = 1;

on protected $fieldsValidate = array(

'extracheckbox' => 'isBool',

on public function getFields()
{
parent::validateFields();

$fields['extracheckbox'] = intval($this->extracheckbox);

then database is 1 if $extracheckbox = 0 then db is 0
How to give decide to customer about tick or not
coz code in order-adress.tpl dont give a changes

<input type="checkbox" name="extracheckbox" id="extracheckbox" value="1" {if $extracheckbox == 1}checked="checked"{/if} />
{l s='Extra question'}.

in order.php:

/* Carrier step */

$cart->extracheckbox = (isset($_POST['extracheckbox']) AND !empty($_POST['extracheckbox'])) ? 1 : 0;

Where is mistake?

Did you find a solution ? i'm interest too.

there is more files to change, the PaymentModule.php, Cart.php, order-carrier.tpl, order-detail.tpl ( for the customer account)

if you are using a payment module witch integrate the code of PaymenModules.php, you have to change it too ( /modules/yourpayment)

You have to add a new entry in the cart table too of the database (table Cart and Orders).
