Customizing Onepage Checkout - Remove shipping_method

Give our namespace name - “Digg“. So you have a folder in app/local/Digg for modules and module “Checkout”.

You must add next files to you module:

1.Block Digg/Checkout/Block/Onepage/Shipping/Method.php
2.Controller Digg/Checkout/controllers/OnepageController.php
3.Model Digg/Checkout/Model/Type/Onepage.php
4.Configuration Digg/Checkout/etc/config.xml

1. Block (Method.php)


To disable Shipping Method for checkout list, you must hide it. Our custom shipping method inherited from core Mage_Checkout_Block_Onepage_Shipping_Method class. Overload method isShow and return false:
class Digg_Checkout_Block_Onepage_Shipping_Method extends


2. Controller (OnepageController.php)


Important:Controllers have no autoloading so you must include it manualy. Overwrite the function saveShippingAction() and saveBillingAction() to skip shipping method to payment with the following code:

_expireAjax()) {
return;
}
if ($this->getRequest()->isPost()) {
$data = $this->getRequest()->getPost('shipping', array());
$customerAddressId = $this->getRequest()->getPost('shipping_address_id', false);
$result = $this->getOnepage()->saveShipping($data, $customerAddressId);
if (!isset($result['error'])) {
$result['goto_section'] = 'payment';
$result['update_section'] = array(
'name' => 'payment-method',
'html' => $this->_getPaymentMethodsHtml()
);
}
$this->getResponse()->setBody(Mage::helper('core')->jsonEncode($result));
}
}
public function saveBillingAction()
{
if ($this->_expireAjax()) {
return;
}
if ($this->getRequest()->isPost()) {
$data = $this->getRequest()->getPost('billing', array());
$customerAddressId = $this->getRequest()->getPost('billing_address_id', false);
$result = $this->getOnepage()->saveBilling($data, $customerAddressId);
if (!isset($result['error'])) {
/* check quote for virtual */
if ($this->getOnepage()->getQuote()->isVirtual()) {
$result['goto_section'] = 'payment';
$result['update_section'] = array(
'name' => 'payment-method',
'html' => $this->_getPaymentMethodsHtml()
);
}
elseif (isset($data['use_for_shipping']) && $data['use_for_shipping'] == 1) {

$result['goto_section'] = 'payment';
$result['update_section'] = array(
'name' => 'payment-method',
'html' => $this->_getPaymentMethodsHtml()
);
}
else {
$result['goto_section'] = 'shipping';
}
}
$this->getResponse()->setBody(Mage::helper('core')->jsonEncode($result));
}
}
}

?>




3. Model (Onepage.php)


The simplest way to ask magento to ignore shipping info is to change validation rule. Te following code overwriting validateOrder() method. I just removed part of original code that validate non-virtual products


getQuote()->getIsMultiShipping()) {
Mage::throwException($helper->__('Invalid checkout type.'));
}

$addressValidation = $this->getQuote()->getBillingAddress()->validate();
if ($addressValidation !== true) {
Mage::throwException($helper->__('Please check billing address information.'));
}

if (!($this->getQuote()->getPayment()->getMethod())) {
Mage::throwException($helper->__('Please select valid payment method.'));
}
}
}

?>



4. Configuration (config.xml)


Last step is configurate our module. The main idea is to ask Magento first searching action methods in our Digg module and if it didn’t found use core.
