Magento registration with Billing & Shipping address

Is it possible that when user register in Magento, that time he also saves his Addresses (Billing & Shipping)

Create a module with a controller that extends the Mage_Customer_AccountController, containing createPostAction(). I duplicated the bit that handles the billing address, find this if-block:

if ($this->getRequest()->getPost('create_address')) { 

And add this to the end of it:

if ($this->getRequest()->getPost('create_shipping_address')) {
$shippingAddress = Mage::getModel('customer/address');
$shippingAddressForm = Mage::getModel('customer/form');
$shippingAddressForm->setFormCode('customer_register_address')
    ->setEntity($shippingAddress);

$shippingAddressData = array(
    'firstname'  => $addressData['firstname'],
    'lastname'   => $addressData['lastname'],
    'company'    => $this->getRequest()->getPost('shipping_company'),
    'street'     => $this->getRequest()->getPost('shipping_street'),
    'city'       => $this->getRequest()->getPost('shipping_city'),
    'country_id' => $this->getRequest()->getPost('shipping_country_id'),
    'region'     => $this->getRequest()->getPost('shipping_region'),
    'region_id'  => $this->getRequest()->getPost('shipping_region_id'),
    'postcode'   => $this->getRequest()->getPost('shipping_postcode'),
    'telephone'  => $this->getRequest()->getPost('shipping_telephone'),
    'fax'        => $this->getRequest()->getPost('shipping_fax')
    );

$shippingAddressErrors = $addressForm->validateData($shippingAddressData);

if ($shippingAddressErrors === true) {
    $shippingAddress->setId(null)
        ->setIsDefaultBilling($this->getRequest()->getParam('shipping_default_billing', false))
        ->setIsDefaultShipping($this->getRequest()->getParam('shipping_default_shipping', false));

    $shippingAddressForm->compactData($shippingAddressData);

    $customer->addAddress($shippingAddress);

    $shippingAddressErrors = $shippingAddress->validate();

    if (is_array($shippingAddressErrors)) {
        $errors = array_merge($errors, $shippingAddressErrors);
    }
} else {
    $errors = array_merge($errors, $shippingAddressErrors);
}}

Of course you also need to duplicate the form in your themes template/customer/form/register.html, specifically the code inside this if-block:

if($this->getShowAddressFields()): ?>

Prefix all the field names IDs and in the copied code with shipping_. In the JavaScript at the bottom you need to duplicate the RegionUpdater line, like so:

new RegionUpdater('country',          'region',          'region_id', <?php echo   $this->helper('directory')->getRegionJson() ?>, undefined, 'zip');
new RegionUpdater('country', 'shipping_region', 'shipping_region_id', <?php echo $this->helper('directory')->getRegionJson() ?>, undefined, 'zip'); 

(almost) complete code can be found here:

It works perfectly
