Adding step to Magento onepage checkout process - magento

Question

I am try to create an additional step in the Magento onepage checkout process.
I am following the tutorial located at http://www.excellencemagentoblog.com/magento-onestep-checkout-add-step but specifically adding a step at the end before the review.
My folder / file structure is as follows. (Ignore widget.xml)
I have uploaded the code in it's current state to this gist:
https://gist.github.com/Relequestual/5263498
I have the theme set to 'new'.
I am var_dumping the $this->getSteps() which shows that the 'testcheck' returns null.
In config.xml, if I change under gobal, blocks, checkout, rewrite, onepage to the same class with '_TestCheck' on the end, the checkout doesn't display at all, but 'Test Check' appears in the progress section on the right. When I revert this change, it then shows as not being null in the var dump like so...
But, I still don't see the step actually added to the page.
I've not done any magento before, so feel a bit in over my head. I expect there is some problem with the xml configuration files, but I've been working on this for 2 days now, and am somewhat lost as to what else I can try.
I know this question may sound similar to others, which it is, however I can't find a question where the OP has the same symptoms as what I am seeing.

Answer 1

By default magento gives some checkout steps. But Sometime you need to add extra information from the customer for future reference. A common requested customization is to add the Custom Form in default checkout process.
This is not good practice to touch core files. You can do this via overriding Modules.
In this example Comapnyname is Ipragmatech and Module name is Checkoutstep.
Step1: Add Custom step in the checkout process
Open the Ipragmatech > Checkoutstep > Block > Onepage> Checkoutstep.php file and write the following code
class Ipragmatech_Checkoutstep_Block_Onepage_Checkoutstep extends Mage_Checkout_Block_Onepage_Abstract
{
protected function _construct()
{
$this->getCheckout()->setStepData('checkoutstep', array(
'label' => Mage::helper('checkout')->__('Invitation to participation'),
'is_show' => true
));
parent::_construct();
}
}
Step2: Add steps which and where you want in the checkout process
Open the Ipragmatech > Checkoutstep > Block > Onepage> Checkoutstep.php file and write the following code
class Ipragmatech_Checkoutstep_Block_Onepage extends Mage_Checkout_Block_Onepage
{
public function getSteps()
{
$steps = array();
if (!$this->isCustomerLoggedIn()) {
$steps['login'] = $this->getCheckout()->getStepData('login');
}
$stepCodes = array('billing', 'shipping', 'shipping_method', 'payment', 'checkoutstep', 'review');
foreach ($stepCodes as $step) {
$steps[$step] = $this->getCheckout()->getStepData($step);
}
return $steps;
}
}
Step3: Grab the submitted value of custom form and set the values of Custom form
Open the ipragmatech > Checkoutstep > controllers > OnepageController.php and write the following fucntion
public function saveCheckoutstepAction()
{
$this->_expireAjax();
if ($this->getRequest()->isPost()) {
//Grab the submited value
$_entrant_name = $this->getRequest()->getPost('entrant_name',"");
$_entrant_phone = $this->getRequest()->getPost('entrant_phone',"");
$_entrant_email = $this->getRequest()->getPost('entrant_email',"");
$_permanent_address = $this->getRequest() ->getPost('permanent_address',"");
$_address = $this->getRequest()->getPost('local_address',"");
Mage::getSingleton('core/session') ->setIpragmatechCheckoutstep(serialize(array(
'entrant_name' =>$_entrant_name,
'entrant_phone' =>$_entrant_phone,
'entrant_email' =>$_entrant_email,
'permanent_address' =>$_permanent_address,
'address' =>$_address
)));
$result = array();
$redirectUrl = $this->getOnePage()->getQuote()->getPayment() ->getCheckoutRedirectUrl();
if (!$redirectUrl) {
$this->loadLayout('checkout_onepage_review');
$result['goto_section'] = 'review';
$result['update_section'] = array(
'name' => 'review',
'html' => $this->_getReviewHtml()
);
}
if ($redirectUrl) {
$result['redirect'] = $redirectUrl;
}
$this->getResponse()->setBody(Zend_Json::encode($result));
}
}
Step4: Save Custom Form information
When checkout_onepage_controller_success_action
event hook is called. Open the Ipragmatech > Checkoutstep > Model >Observer.php and write the following
class Ipragmatech_Checkoutstep_Model_Observer {
const ORDER_ATTRIBUTE_FHC_ID = 'checkoutstep';
public function hookToOrderSaveEvent() {
if (Mage::helper('checkoutstep')->isEnabled()) {
$order = new Mage_Sales_Model_Order ();
$incrementId = Mage::getSingleton ( 'checkout/session' )->getLastRealOrderId ();
$order->loadByIncrementId ( $incrementId );
// Fetch the data
$_checkoutstep_data = null;
$_checkoutstep_data = Mage::getSingleton ( 'core/session' )->getIpragmatechCheckoutstep ();
$model = Mage::getModel ( 'checkoutstep/customerdata' )->setData ( unserialize ( $_checkoutstep_data ) );
$model->setData ( "order_id",$order["entity_id"] );
try {
$insertId = $model->save ()->getId ();
Mage::log ( "Data successfully inserted. Insert ID: " . $insertId, null, 'mylog.log');
} catch ( Exception $e ) {
Mage::log ( "EXCEPTION " . $e->getMessage (), null, 'mylog.log' );
}
}
}
}
