Description

It is possible to dynamically inject variables in content view templates by listening to the  ezpublish.pre_content_view  event.

The event listener method receives an eZ\Publish\Core\MVC\Symfony\Event\PreContentViewEvent object

Example

The following example will inject foo and osTypes variables in all content view templates.

?
<?php
 
namespace Acme\DemoBundle\EventListener;
use eZ\Publish\Core\MVC\Symfony\Event\PreContentViewEvent;
 
class PreContentViewListener
{
    public function onPreContentView( PreContentViewEvent $event )
    {
        // Get content view object and inject whatever no need.
        // You may add some custom business logic here.
        $contentView = $event->getContentView();
        $contentView->addParameters(
            array(
                 'foo'          => 'bar',
                 'osTypes'      => array( 'osx', 'linux', 'win' )
            )
        );
    }
}
