Magento – Redirect in OnePage Checkout during checkout in “Shipping Method” to shipping provider’s web (onepage)

checkoutonepage-checkoutredirectshippingshipping-methods

I'm using OnePage module checkout.

I created my shipping method module. If is my method selected, need to redirect to provider's web. Here customer choose closest place to his shipping address and then it's redirected back to checkout. What's the best way where to do redirection? In controller? Is is even possible (isn't it restricted just to "Payment methods")?

UPDATED:
There seems to be two ways:

Redirect just after "Shipping Method" section and to be returned back to OnePage by provider's web after choosing the place. This requires to hack skin/frontend/base/default/js/opcheckout.js and app/code/core/Mage/Checkout/controllers/OnepageController.php, because when it goes back to OnePage from providers's web, it needs to:
1. Save new address (previously choosen in "Shipping" section.
2. Jump jump to next section ("Payment method") – i.e. skip everything up to "Shipping Method".
Another option seems to be to hack OnepageController.php to do redirect at the beginning of successAction() method.

I also wanted to get inspiration from PayPal modules, which do redirect, but I wasn't succeed.

You can do this by Magento event observer functionality whenever magento predispatch a controller then trigger event controller_action_predispatch_youfullaction

Mage::dispatchEvent('controller_action_predispatch_' .
    this->getRequest()->getRouteName(), array('controller_action' => $this));

you need trigger an event when shipping method is select and click save button to goto next button you need event and redirect to third party from observer.

Here is an example that depends on Magento default

checkout onepage and trigger event on
controller_action_predispatch_checkout_onepage_saveShippingMethod

<frontend>
        <events>
            <controller_action_predispatch_checkout_onepage_saveShippingMethod>
                <observers>
                    <my_fire_events>
                        <class>magento38137/observer</class>
                        <method>myredirection</method>
                    </my_fire_events>
                </observers>
            </controller_action_predispatch_checkout_onepage_saveShippingMethod>
        </events>
</frontend>

How to Redirect to Cart When Shipping Address Changes in Magento

Magento saves all checkout step data using AJAX.

Magento has a feature to go back to the cart page whenever an AJAX request goes to onFailure state during any of the checkout steps.

.....
method:'get',
            onFailure:this.ajaxFailure.bind(this),
            onComplete: function(){
 ....
.....
ajaxFailure: function(){
        location.href = this.failureUrl;
    },
......

An AJAX response calls the onFailure() function whenever a header response isHTTP/1.1 500 Internal Server Error`.

 $this->getResponse()->clearHeaders()->setHeader('HTTP/1.1', '500 Internal Server Error')->sendResponse();
 exit;

Or use 403 (permission denied):

$this->getResponse()->clearHeaders()->setHeader('HTTP/1.1', '403 Forbidden')->sendResponse()->sendResponse();
exit;

...Or 503 (service unavailable):

$this->getResponse()->clearHeaders()->setHeader('HTTP/1.1', '503 Service Unavailable')->sendResponse();
exit;

In your case you need to send a 500/403/503 header response code to ensure that the Prototype AJAX onFailure is called.

saveShipping() function saves shipping data using AJAX` and the response is the JSON content.

On receipt of this response the checkout is going to move to the next step.

That means that $this->_redirect('checkout/cart'); is not being run.

Checkout Redirect Issue – Fix Redirect to Cart After Selecting Shipping Method

To me, it clearly sounds like your Magento is badly corrupted.

I can't confirm that because the URL you pasted links to a Shopify website but let me explain.

Regarding the error

That error happens in a very critical file in terms of security, app/code/core/Mage/Payment/Model/Method/Cc.php being the file that handles the Credit Card payment method.

Having an error thrown here in a core file is already a red flag.

On top of that, line 388 does not exist in a native Magento 1.4.0.1 install, you can find the original file here: https://github.com/OpenMage/magento-mirror/blob/1.4.0.1/app/code/core/Mage/Payment/Model/Method/Cc.php

That is a super red flag.

Two possibilities:

the original developer(s) modified the core files, which is a very bad practice but I can't see why they would change this file.
your install got corrupted by a hacker who used a security breach to modify this file in order to steal Credit Card Information.

Unfortunately, I have a bad feeling that you're in the second case.

That bad feeling comes from the fact that the key that does not exist and that triggers the error is SESSIIID. It looks to me that the corrupted file is trying to steal the session ids to be able to retrieve the credit card details.

One of the most famous Magento vulnerability regarding credit card hijacking uses SESSIID (with two i, there's three in your code) and I'm pretty that's what the hacker wanted to achieve: https://www.byte.nl/blog/widespread-credit-card-hijacking-discovered

Fixing the problem

First, I suggest you run the website against MageReport: https://www.magereport.com/

It will help you finding out the vulnerabilities of your website.

Second, I suggest you roll back all the core files to the original ones.

My personal suggestion would be to use the MageRun plugin developed by AOE to find out which core files have been modified: https://github.com/AOEpeople/mpmd#command-mpmdcorehacks

Finally once you've rolled back the core files to their original state, I suggest you install all the missing patches. You can download them here: https://www.magentocommerce.com/download
