How to auto fill shipping method Magento for onepagechekout - magento

Question

I want to auto fill the shipping method automatically and not show it on the onepage checkout. I was able to hide the shipping method on my Onepagechekout by changing this on app/code/local/Mage/Checkout/controllers/OnepageController.php:
/**
* save checkout billing address
*/
public function saveBillingAction()
{
if ($this->_expireAjax()) {
return;
}
if ($this->getRequest()->isPost()) {
// $postData = $this->getRequest()->getPost('billing', array());
// $data = $this->_filterPostData($postData);
$data = $this->getRequest()->getPost('billing', array());
$customerAddressId = $this->getRequest()->getPost('billing_address_id', false);
if (isset($data['email'])) {
$data['email'] = trim($data['email']);
}
$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()
);
$result['allow_sections'] = array('shipping');
$result['duplicateBillingInfo'] = 'true';
} else {
$result['goto_section'] = 'shipping';
}
}
$this->saveShippingMethodAction();
$this->getResponse()->setBody(Mage::helper('core')->jsonEncode($result));
}
}
As you can see I changed the link where I redirect the next step after billing action to the payment step.
In order to auto-save a shipping method, I added
$this->saveShippingMethodAction();
at the end of the function, and this method looks like here:
public function saveShippingMethodAction()
{
$this->_expireAjax();
if ($this->getRequest()->isPost()) {
/* $this->savePaymentAction(); */
$data = $this->getRequest()->getPost('shipping_method', 'flatrate_flatrate');
$result = $this->getOnepage()->saveShippingMethod($data);
$this->getResponse()->setBody(Zend_Json::encode($result));
}
}
So what I did is try to include automatically flatrate_flatrate method as the default one.
But when I try to finish a sale, it says I didn't specify a shipping method. Any idea on why it doesn't work?

Now you need to force the shipping_method in the quote and in the session :
$forcedMethod = "your_method_code";
$this->getOnePage()->getQuote()
->getShippingAddress()
->setShippingMethod($forcedMethod)
->save();
Mage::getSingleton('checkout/session')->setShippingMethod($forcedMethod);
And just before you call :
$this->saveShippingMethodAction();
add a :
$this->getRequest()->setPost('shipping_method', $forcedMethod);
It should work ;)
