Multiple uploads avec VichUploader

**dubitoph** · 12/12/2018, 16h08

Bonjour,

Savez-vous s'il est possible d'envoyer, via un seul formulaire, un nombre indéfini de fichiers avec VichUploader (un annonce contenant plusieurs photos)? J'ai trouvé de la documentation pour un seul fichier mais pas pour plusieurs.

Merci d'avance pour votre réponse.

J'ai une entité Advert qui peut être liée à plusieurs entités Image. Mon but est d'avoir la possibilité, lorsqu'on encode une annonce, de pouvoir y joindre, dans un même formulaire, plusieurs photos. Pour cela, j'utilise vichUploader, LippImagine et le webpack Encore.

Pour se faire voici mes différentes sources :
