Magento:在注册时选择客户组

尝试在Magento Pro v1.11中添加group_id单选按钮集

跟随
http://phpmagento.blogspot.com/2012/01/how-to-show-customer-group-selecter-in.html和
http://developersindia.info/magento/magento-override-frontend-controller.html，
这在一定程度上起作用，但group_id没有写入数据库。

我的模块，到目前为止：

目录结构

app/code/local
- WACI
-- Customer
--- controllers
---- AccountController.php
--- etc
---- config.xml

config.xml

<config>
    <modules>
        <WACI_Customer>
            <version>0.1.0</version>
        </WACI_Customer>
    </modules>
    <global>
        <fieldsets>
            <customer_account>
                <group_id><create>1</create></group_id>
            </customer_account>
        </fieldsets>
    </global>
    <frontend>
        <routers>
            <customer>
                <args>
                    <modules>
                        <WACI_Customer before="Mage_Customer_AccountController">
                            WACI_Customer
                        </WACI_Customer>
                    </modules>
                </args>
            </customer>
        </routers>
    </frontend>
</config>

AccountController.php

<?php
/**
 *Customer account controller
 *
 * @package     WACI_Customer
 */
require_once Mage::getModuleDir('controllers', 'Mage_Customer').DS.'AccountController.php';
class WACI_Customer_AccountController extends Mage_Customer_AccountController
{
    /**
    * Create customer account action
    */
    public function createPostAction()
    {
// contents of createPostAction(), with some extra logic
            /**
             * Initialize customer group id
             */
            /* catch groupid at account creation */
            if($this->getRequest()->getPost('group_id')){ 
                $customer->setGroupId($this->getRequest()->getPost('group_id'));
            } else {
                $customer->getGroupId(); 
            } 

 // rest of method
    }
}

主题/persistent/customer/form/register.phtml

<div class="input-box">
    <label for="group_id"><?php echo $this->__('Select your customer group') ?></label><br />
    <?php 
        $groups = Mage::helper('customer')->getGroups()->toOptionArray();
        foreach ($groups as $group){
            echo '<input type="radio" name="group_id" value="'.$group['value'].'" class="validate-radio" >'.$group['label'].'</input><br/>';
        }
    ?>
</div>

因此，带有组的单选按钮在注册时显示良好，但数据没有写入数据库，因为组在admin/manage customers 中仍然显示为一般

• 我真的不想修改核心文件，正如文章所描述的那样
• 我不确定我是否正确地覆盖了法师accountController类（也许有更好的方法？）

我搞砸了什么
