I have tried this with plugins and preferences and I seem to be missing the best practise method.

Why would Magento render the page so early that you can't modify the layout via plugin?

Am I missing something here?

I want to add an extra layout handle if the product has a certain attribute with x value. What is best practise here?

Possibly it isn't necessary to use a plugin if the event is provided.

Try use the event


The event is dispatched in


protected function loadLayoutUpdates()
    /* dispatch event for adding handles to layout update */
        ['full_action_name' => $this->request->getFullActionName(), 'layout' => $this->layout]

    return $this;

Actually I think that magento 2 plugins is rather powerful feature, but, let me say, it breaks out of the application architecture. I’d rather prefer the event usage to the plugin usage.

  • This would run for every layout load for the sake of one type of product. I just can't bring myself to do it. Mar 15, 2017 at 13:51
  • You can check in your own observer class any product parameter, attribute or attribute set. Only if it correspond your specific condition - add layout handle to layout.

    It is an example for magento 1 - but I assume, for magento 2 there are no essential distinctions: magebase.com/magento-tutorials/creating-custom-layout-handles

  • Would you recommend this with performance in mind? Mar 15, 2017 at 14:15
  • I can't see any performance problem, using the event only for the product page with simplest verification by product attribute.
