Upload profile picture in registration process - FOSUserBundle - symfony

Question

I have a problem in the registration process when using FOSUserBundle. Instead of the real path of the image I'm trying to upload, in the database, it always saves initial value under the path column and the image is not uploaded in the directory I have defined.
