php - Symfony2 and Doctrine - @ORM\PostPersist() does not work -

i have file upload function on symfony2 project. used http://symfony.com/doc/current/cookbook/doctrine/file_uploads.html example.

the problem @orm\postpersist() not trigered , file not stored in specific folder.

here have:

1 entity "manuscript" manage file:

 /**  * @orm\postpersist()  * @orm\postupdate()  */ public function upload() {     if (null === $this->file) {         return;     }      $this->file->move( $this->getuploadrootdir().date('ymdhis').'_'.$this->file->getclientoriginalname() ); } 

i tryed put var_dump() there var_dump() never actioned, never entering there.

in form, have file:

 public function buildform(formbuilderinterface $builder, array $options) {     $builder->add('file', 'file', array('label'=> 'htm file', 'required' => true)); } 

finally, in controller, have

if ($request->ismethod('post')) {          $form->bind($request);          if ($form->isvalid()) {             $em_scipub->persist($enquiry);               $em_scipub->flush();             .... 

i fixed issue, think forgot add @orm\haslifecyclecallbacks

so, in manuscript entity, should that:

/** * manuscripts * * @orm\table(name="manuscripts") * @orm\entity * @orm\haslifecyclecallbacks *  */  class manuscript {   ....
