In magento 1 i can do it like this

$session            = Mage::getSingleton('core/session');
$session->addSuccess($this->__('Your Request has been received. One of our sales representatives will contact you shortly.'));

Same thing how can i do it in Magento2? Tried this but not working .

  • You can set and get the values by session, do you want use only session ? have you tried Message\ManagerInterface $messageManager – Krishna ijjada Jul 26 '16 at 17:26

In Magento 2, we can do achieve this in two steps:

First, we need to assign the message to 'messageManager' from your module as below:

$this->messageManager->addSuccess(__('This is a success message.'));

Secondly, we need to assign a placeholder for the message through frontend layout xml used in the module as given below inside the <body> tag:

<referenceContainer name="page.messages">
        <block class="Magento\Framework\View\Element\Template" name="ajax.message.placeholder" template="Magento_Theme::html/messages.phtml"/>
        <block class="Magento\Framework\View\Element\Messages" name="messages" as="messages" template="Magento_Theme::messages.phtml"/>

The above layout update will make use of the magento's message template to display the messages.

  • ,How to I add this reference container in backend – Jaisa Feb 8 '18 at 6:16
  • Is the XML really needed here? – Wouter Jun 28 '18 at 6:44

Magento2 is using MessageInterface to add all message, please use below code to show Messages

Magento Message Framework class


use below code in your file to add messages,

protected _messageManager;

public function __construct(\Magento\Framework\View\Element\Template\Context $context, \Magento\Framework\Message\ManagerInterface $messageManager) {
        $this->_messageManager = $messageManager;

and then add below functions in your methods to show messages:

$this->_messageManager->addError(__("Error Message"));
$this->_messageManager->addSuccess(__("Success Message"));

I hope this will help you fixing your issue.

  • which file i want to add this code – Naveenbos Jul 27 '16 at 6:03

You can try below code to add success or error Messages.

$this->messageManager was in parent class calling from


$this->messageManager = $context->getMessageManager();

class Post extends \Magento\Framework\App\Action\Action

    public function __construct(
        \Magento\Framework\App\Action\Context $context
    ) {
    public function execute()

$data = $this->getRequest()->getPostValue();

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();       
$question = $objectManager->create('Myvendor\Mymodule\Model\Feedback');

/****** set your data *********/

$this->messageManager->addSuccess( __('Thanks for your valuable feedback.') );

/* ***** OR

$this->messageManager->addError('There is something went wrong');

You can assign messages to messageManager


You can find some more information on how to Display notification messages

Hope this helps.

    Do not use the Object Manager directly. – Jisse Reitsma Nov 12 '17 at 9:14

Custom layout file

<referenceContainer name="page.messages">
        <block class="Magento\Framework\View\Element\Messages" name="messages" as="messages"/>

Use this in your custom layout file to show the Error message and Success message for your custom template file.

Custom Controller file

                    __('Thanks for Submission'));
    }catch (\Exception $e) {
                    __('We can\'t process your request right now. Sorry, that\'s all we know.'));
