Mettre à jour une image et conserver l'ancienne si le champ est vide

J'ai un formulaire dans mon interface d'administration qui me permet de publier un article en téléchargeant une image et j'ai un autre formulaire qui me permet de modifier un article. Lorsque je modifie mon article, je voudrais conserver l'image précédente si le champ est vide (donc "null") ou instancier ma nouvelle image en supprimant l'image précédente s'il y en avait une, mais je n'ai pas réussi.Mettre à jour une image et conserver l'ancienne si le champ est vide

Actuellement, si je modifie mon article en laissant vide mon image de champ, doctrine définit mon champ image_id à NULL dans la base de données.

J'ai une entité "Image" liée à OneToOne avec mon entité "Article" et EditArticleType qui définit les données de l'élément actuel à sa valeur par défaut.

Mon contrôleur:

public function modifierArticleAction(Article $article, Request $request, $id)

En vous entité article essayez de modifier chaque champ d'image comme ceci:

public function setImage($image) 
{ 
    if (!is_null($image)) { 
     $this->image = $image; 
    } 

    return $this; 
}

...

public function setImage10($image) 
{ 
    if (!is_null($image)) { 
     $this->image10 = $image; 
    } 

    return $this; 
}

Cette logique doit empêcher la définition de l'entité image si elle est nulle.
