How to edit embedded form with file upload in symfony2 and doctrine mongodb - mongodb

Question

I have document called aboutMe
and it has another embedded document called projects to add many projects (prototype)
The projects has project name and image for the project.
i created a formType for aboutMe document and i embedded the project form inside the aboutMe form to be able to add many projects prototype.
The problem is updating the project->image when the user didn't change the old project image.
doctrine updating the old embedded project document with a null image.
I Need to keep the old image name if the user didn't upload a new one

And here's the controller that i want to be able to keep the old image
/**

*
* #Route("/profile/about-me/update", name="profile_about_me_update")

{
$dm = $this->get('doctrine.odm.mongodb.document_manager');
$user = $this->getUser();
$entity = $dm->getRepository('AboutMeIndex')->findOneBy(array('user.$id' => (int)$user->getId()));
if (!$entity) {
throw $this->createNotFoundException('Unable to find entity Document.');
}
$editForm = $this->createForm(new AboutMeIndexType(), $entity);
$editForm->submit($request);
if ($editForm->isValid()) {
if($entity->getProjects()->getImage() is newImage){
$entity->uploadEmbeddedPhotos('projects', 'profile/aboutMe/');
}else{
// Keep the old Image
}
$dm->persist($entity);
$dm->flush();
}
}
