Update and remove cached image using Liipimaginebundle

Here is a solution that works fine

services:    project.cacheimage_listener:        class: Project\DashboardBundle\Listener\CacheImageListener        arguments: ["@liip_imagine.cache.manager"]        tags:            - { name: doctrine.event_listener, event: postUpdate }            - { name: doctrine.event_listener, event: preRemove }

create the listener

namespace Project\DashboardBundle\Listener;use Doctrine\ORM\Event\LifecycleEventArgs;use Project\DashboardBundle\Entity\Image;class CacheImageListener{protected $cacheManager;public function __construct($cacheManager){    $this->cacheManager = $cacheManager;}public function postUpdate(LifecycleEventArgs $args){    $entity = $args->getEntity();    if ($entity instanceof Image) {        // clear cache of thumbnail        $this->cacheManager->remove($entity->getUploadDir());    }}// when delete entity so remove all thumbnails related public function preRemove(LifecycleEventArgs $args){    $entity = $args->getEntity();    if ($entity instanceof Image) {        $this->cacheManager->remove($entity->getWebPath());    }}}
