Updating and Deleting a Cached Image Using Liipimaginebundle

Question

I am using liipimaginebundle and everything works fine except for deleting and updating cached images when updating the original image. I would like to know how I can do this

config.yml

liip_imagine: resolvers: default: web_path: ~ filter_sets: cache: ~ travel_75_55: quality: 80 filters: thumbnail: { size: [75, 55], mode: outbound } travel_270_161: quality: 75 filters: thumbnail: { size: [270, 161], mode: outbound} 

And this is Object: Image

 /** * Image * * @ORM\HasLifecycleCallbacks */ class Image { //................. public $file; public function setFile($file) { $this->file = $file; if (null !== $this->url) { $this->tempFilename = $this->url; $this->url = null; $this->alt = null; } } public function getFile() { return $this->file; } private $tempFilename; /** * @ORM\PrePersist() * @ORM\PreUpdate() */ public function preUpload() { if (null === $this->file) { return; } $this->url = $this->file->guessExtension(); $this->alt = $this->file->getClientOriginalName(); } /** * @ORM\PostPersist() * @ORM\PostUpdate() */ public function upload() { if (null === $this->file) { return; } if (null !== $this->tempFilename) { $oldFile = $this->getUploadRootDir().'/'.$this->id.'.'.$this->tempFilename; if (file_exists($oldFile)) { unlink($oldFile); } } $this->file->move( $this->getUploadRootDir(), $this->id.'.'.$this->url ); } /** * @ORM\PreRemove() */ public function preRemoveUpload() { $this->tempFilename = $this->getUploadRootDir().'/'.$this->id.'.'.$this->url; } /** * @ORM\PostRemove() */ public function removeUpload() { if (file_exists($this->tempFilename)) { unlink($this->tempFilename); } } public function getUploadDir() { return 'uploads/img/travels'; } protected function getUploadRootDir() { return __DIR__.'/../../../../web/'.$this->getUploadDir(); } public function getWebPath() { return $this->getUploadDir().'/'.$this->getId().'.'.$this->getUrl(); } }

Here is a solution that works great

 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 a 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()); } } }
