That fonction is called by the main view. So for example product / listing.php or product / show.php and not for the sub view files called within the main view file. So normally, you should never have the condition $view->getLayout() === 'show_quantity' valid in your plugin. Are you sure that the js code you're looking at comes from the PHP code you gave in your message ?

I've the same problem with my component for customize products, the html code was duplicated many times but I've solved this problem by creating a page for the component Last edit: 8 years 7 months ago by [Krok](/forum/user/49481-krok "View Krok's Profile").
