$entity ??????? how I can get file content here ?

The file is linked to the attachment entity. You can call the getFileData function in the attachment service class and pass the file id to it.

Thank you very much for your answer.
But how I can get attachment entity from document hook ?

[AgentT]

Inject the service class in the constructor like:

use Espo\Services\Attachment;

class Document{
  public function __construct(Attachment $att)
  {
    $this->attachmentService = $att;
  }
}

Then use $this->attachmentService from the beforeSave function to call the getFileData function.

I'm very much sorry. How I can get attachment entity from Document entity ?

You don't really need the Attachment entity, you just need it's ID.

You can get the ID by going: $entity->get('fileId').

If you need the Attachment, then:

$attachmentEntity = $this->entityManager->getEntity('Attachment', $entity->get('fileId'));
