I am currently implementing a behavior where I will check the quote items in cart, then check if it contains my custom attributes. If true, then it will redirect me to a specific page(CMS) page.
This behavior should trigger before place order is processed.

I already tried using, observer events: sales_order_place_before and checkout_submit_before. I was not successful in implementing the redirect in the observer. The place order process seems to ignore redirects from the observer.

Here is my code:


<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
<event name="sales_order_place_before">
    <observer name="observer_name" instance="Package\ModuleName\Observer\BeforePlaceOrder"/>


 public function execute(Observer $observer)
    $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
    /** @var \Magento\Framework\UrlInterface $url */
    $url = $objectManager->create('\Magento\Framework\UrlInterface');

    /** @var \Magento\Framework\App\ResponseInterface $response */
    $response = $objectManager->create('\Magento\Framework\App\ResponseInterface');

    $customerBeforeAuthUrl = $url->getUrl('support-plan-option'); //you can change the routh path to your cms page

    My issue is related to this: magento.stackexchange.com/questions/165208/… I already tried their suggestions from the link. Commented Oct 14, 2019 at 2:37
  • I think you are missing the return $response;

  • I aldread tried returning the whole line of $response->setRedirect($customerBeforeAuthUrl)->sendResponse(); Commented Oct 14, 2019 at 8:03
  • it seems the observer disregards your redirection code, what if you put die() or exit() after you return the $response. check if your redirect code will work after

  • Hi @fnsthird, if I put die or exit, redirection won't go to my desired page it was redirected instead to checkout cart page due to the catch condition from native magento 2 place order process. Commented Oct 15, 2019 at 11:03

Try using the following in your constructor:

  • \Magento\Framework\App\ResponseFactory to set the redirection and

  • \Magento\Framework\UrlInterface to set the URL to redirect.

  • I already tried this approach but still not working. Commented Oct 14, 2019 at 3:05
  • how about using \Magento\Framework\App\Response\RedirectInterface ?

  • also @EubieAluad can you confirm that your event observer is working?

  • yes @fmsthird my observer is working . Also I have tried RedirectInterface. But still redirection isn't working Commented Oct 14, 2019 at 4:19
  • can you include your code implementation in your post

You can simply use this code in your observer to redirect on any specific page.

protected $_redirect;

protected $_actionFlag;

public function __construct(
    \Magento\Framework\App\Response\RedirectInterface $redirect,
    \Magento\Framework\App\ActionFlag $actionFlag
) {
    $this->_redirect = $redirect;
    $this->_actionFlag = $actionFlag;

public function execute(Observer $observer)
    $this->_actionFlag->set('', \Magento\Framework\App\Action\Action::FLAG_NO_DISPATCH, true);
    $this->_redirect->redirect($controller->getResponse(), 'support-plan-option');

Hope this may help you. :)
