How to alter the message shown ("xyz" added to your cart) when we add an item to cart in Drupal 8 commerce 2x. I saw Drupal\commerce_cart\EventSubscriber where the function displayAddToCartMessage(CartEntityAddEvent $event) is written which is responsible for showing the message, is there any method to override it. FINALLY! I Found a solution but i think there has to be a better method than this.I wrote a custom submit handler on Add to Cart Submit => $form['actions']['submit']['#submit'][] = 'example'; and then in function example(array $form, FormStateInterface $form_state) { // TO Unset The message which is shown add an item is added to cart. unset($_SESSION['_symfony_flashes']['status']); // Path To Cart. $link = \Drupal\Core\Url::fromRoute('commerce_cart.page')->toString(); // Your custom message. drupal_set_message(t($get_cart_title.' <a href="@link">added to your cart</a>', array('@link' => $link))); // $get_cart_title is some variable as per requirement. }
