我的表单类型

<?php
namespace L3O1\UserBundle\Form\Type;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;

class ProfileFormType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        // add your custom field
        $builder->add('profilePictureFile');
    }

    public function getParent()
    {
        return 'fos_user_profile';
    }

    public function getName()
    {
        return 'l3o1_user_profile';
    }
}

我的编辑在edit_content.html.twig

中

     <form action="{{ path('fos_user_profile_edit') }}" method="POST" {{ form_enctype(form) }} class="fos_user_profile_edit">

    <!-- left column -->
    <div class="col-md-4 col-sm-6 col-xs-12">
      <div class="text-center">
        <h6>Upload a different photo...</h6>
        <img src="/ProjetSVN/web{{app.user.getWebProfilePicturePath}}" class="avatar img-circle img-thumbnail" alt="avatar">
        {{ form_row(form.profilePictureFile, {'label': 'Profile picture'}) }}
        {{ form_widget(form.profilePictureFile, {'attr': {'class': 'form-control' }})}}
      </div>
    </div>
<div class="form-group">
          <label class="col-md-3 control-label"></label>
          <div class="col-md-8">
            <input type="submit" class="btn btn-primary" value="Save change" type="button">
            <input class="btn btn-default" value="Cancel" type="reset">
          </div>
        </div>
      </form>

感谢您的帮助！

我解决了这个问题。这是因为在我的树枝上，我用{{ form_widget(form.file) }}而不是{{ form_widget(form) }}！但我不确定为什么会这样理解。看来，通过FOSUB，当您更新个人资料时，您必须输入密码进行验证。这就是为什么，我认为它不会上传或更新数据库。

使用FOSUserBundle上传个人资料照片
