Add Alerts

Shopware gives you the possibility to print out alert messages at the top of a page, coming from a Controller or a Subscriber. This is done via so-called flashes.

To do this we call one of two methods. The parameters for both methods are identical however:

  • type - The alert message type. This is one of: 'info' (blue), 'warning' (orange) or 'error' (red)
  • message - The text you want to be printed in the message. (Hint: You can use snippets by calling $this-trans('snippet.name'))

The methods are:

In a Controller​

$this->addFlash(<type>, <message>)

In a Subscriber​

$this->session->getFlashBag()->add(<type>, <message>)

tip

The message will be shown only once on the next possible page that includes the alert.html.twig Template.
