Magento - steps checkout and additional module - magento

Question

Thanks for this forum. I often read it and this is my first question.
The question concerns Magento (1.9.1.0). I wanted to add an additional module that allows customer to write a comment on the order. I've been able to find a module that suits my need on the web. It works perfectly, but there is a big problem: it joins in the final step of the checkout (in particular, after the payment phase). And so, if the customer pays by bank transfer, marking or similar payments, the problem doesn't arise: Magento passes to the next step (order comment) and then order completion.
The problem arises in case of Paypal payment, as Magento redirects customer to Paypal.com and, after making the payment, returns to the store by the end of the order (without going to the next step of the comment). The comment form consisted of 19 files that, once installed in Magento, don't modify any existing files.
I would like to include this form after shipping_method step (and not after payment step) and, therefore, I think I have to modify the file (of the module) that is called Abstract.php (app/code/community/Brainvire/Ordercomment/Controller/Onepage/Abstract.php).
I would be very grateful if you could help me edit that file.
<?php
require_once 'Mage/Checkout/controllers/OnepageController.php';
class Brainvire_Ordercomment_Controller_Onepage_Abstract extends
Mage_Checkout_OnepageController {
/*
* Saving the Payment at Checkout
*/
public function savePaymentAction()
{
$this->_expireAjax();
if ($this->getRequest()->isPost()) {
$data = $this->getRequest()->getPost('payment', array());
try {
$result = $this->getOnepage()->savePayment($data);
}
catch (Mage_Payment_Exception $e) {
if ($e->getFields()) {
$result['fields'] = $e->getFields();
}
$result['error'] = $e->getMessage();
}
catch (Exception $e) {
$result['error'] = $e->getMessage();
}
$redirectUrl = $this->getOnePage()->getQuote()->getPayment()->getCheckoutRedirectUrl();
if (empty($result['error']) && !$redirectUrl) {
$this->loadLayout('checkout_onepage_ordercomment');
$result['goto_section'] = 'ordercomment';
}
if ($redirectUrl) {
$result['redirect'] = $redirectUrl;
}
$this->getResponse()->setBody(Zend_Json::encode($result));
}
}
/*
* Saving the order comment
*/
public function saveOrdercommentAction()
{
$this->_expireAjax();
if ($this->getRequest()->isPost()) {
$_brainvire_Ordercomment = $this->getRequest()->getPost('ordercomment');
Mage::getSingleton('core/session')->setBrainvireOrdercomment($_brainvire_Ordercomment);
$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));
}
}
}
How do I edit this php code to insert Ordercomment after shipping_method step and before payment step?
Thanks

Answer 1

I was able to move the order-comment section by editing two files:
First: Brainvire\Ordercomment\Block\Onepage.php
class Brainvire_Ordercomment_Block_Onepage extends Mage_Checkout_Block_Onepage
{
/**
* getting the steps of Checkout page
*/
public function getSteps()
{
...
$stepCodes = array('billing', 'shipping', 'shipping_method', 'ordercomment', 'payment', 'review'); // moved 'ordercomment' before 'payment'
...
}
}
And then the file you mentioned: Brainvire\Ordercomment\Controller\Onepage\Abstract.php
Remove the savePaymentAction() method and replace with this:
class Brainvire_Ordercomment_Controller_Onepage_Abstract extends Mage_Checkout_OnepageController {
/**
* Shipping method save action
*/
public function saveShippingMethodAction()
{
if ($this->_expireAjax()) {
return;
}
if ($this->getRequest()->isPost()) {
$data = $this->getRequest()->getPost('shipping_method', '');
$result = $this->getOnepage()->saveShippingMethod($data);
/*
$result will have erro data if shipping method is empty
*/
if(!$result) {
Mage::dispatchEvent('checkout_controller_onepage_save_shipping_method',
array('request'=>$this->getRequest(),
'quote'=>$this->getOnepage()->getQuote()));
$this->getOnepage()->getQuote()->collectTotals();
$this->getResponse()->setBody(Mage::helper('core')->jsonEncode($result));
if (empty($result['error']) && !$redirectUrl) {
$this->loadLayout('checkout_onepage_ordercomment');
$result['goto_section'] = 'ordercomment';
}
}
$this->getOnepage()->getQuote()->collectTotals()->save();
$this->getResponse()->setBody(Mage::helper('core')->jsonEncode($result));
}
}
/*
* Saving the order comment
*/
public function saveOrdercommentAction()
{
$this->_expireAjax();
if ($this->getRequest()->isPost()) {
$_brainvire_Ordercomment = $this->getRequest()->getPost('ordercomment');
Mage::getSingleton('core/session')->setBrainvireOrdercomment($_brainvire_Ordercomment);
$result = array();
$result['goto_section'] = 'payment';
$result['update_section'] = array(
'name' => 'payment-method',
'html' => $this->_getPaymentMethodsHtml()
);
$this->getResponse()->setBody(Zend_Json::encode($result));
}
}
}
Once you get this working, you should move these customizations into an override module, or at least copy the modified files to app/code/local, so the original code stays intact.
