我正在使用带有FOS用户包（master）的Symfony2 2.6.4，并且我很难尝试将部分注册从主页传递到注册页面。

目标

我希望用户从主页开始并填写一些信息，然后按提交。我希望将用户传递到注册页面并预先填写他们已经在首页上填写的项目。

我尝试过的事情：
我不确定什么是可行的，并且已经花了很多时间在这上面。我尝试扩展注册控制器，但在我开始处理我的问题之前出现错误，所以我停止了。我的最后一个想法是将会话中的变量传递给被覆盖的注册表单类型，看看我是否可以在那里预填充它。

以前有人做过这样的事情吗？他们肯定不容易。

功劳归于@NawfalSerrar 谢谢你的想法。我很接近，但还不够近！

所以我最终做的是这个。

这是执行该工作的控制器操作。

/**
 * @Route("/", name="Home")
 */
public function indexAction(Request $request)
{
    $form = $this->createForm(new RegisterFormType());
    $form->handleRequest($request);
    if ($form->isValid()) {
        $data = $form->getData();
        $user = new User();
        $session = $this->get('session');
        $registration = array();
        $registration['firstName'] = $data['first'];
        $registration['lastName'] = $data['last'];
        $registration['middleInit'] = $data['middle'];
        $registration['email'] = $data['email'];
        $session->set('registration', $registration);
        return $this->redirect($this->generateUrl("fos_user_registration_register"));
    }
    return $this->render('Bundle:Page:index.html.twig', array(
        'form' => $form->createView(),
    ));
}

然后是前端的表单。

{{ form_start(form,{'attr': {'class': 'reg-page'}}) }}
  <div class="reg-header">
      <h1>Get Started!</h1>
      <p>Already Signed Up? Click <a href="page_login.html" class="color-green">Sign In</a> to login
          your account.</p>
  </div>
  {{ form_errors(form) }}
  <div class="row">
      <div class="col-sm-6">
          {{ form_label(form.first) }}
          {{ form_widget(form.first, {'attr': {'class': 'form-control margin-bottom-10'}}) }}
      </div>
      <div class="col-sm-6">
          {{ form_label(form.middle) }}
          {{ form_widget(form.middle, {'attr': {'class': 'form-control margin-bottom-10'}}) }}
      </div>
      <div class="col-sm-6">
          {{ form_label(form.last) }}
          {{ form_widget(form.last, {'attr': {'class': 'form-control margin-bottom-10'}}) }}
      </div>
  </div>
  {{ form_label(form.email) }}
  {{ form_widget(form.email, {'attr': {'class': 'form-control'}}) }}
  <div class="row">
      <div class="col-lg-6 text-right">
          {{ form_widget(form.save, {'attr': {'class': 'btn-u'}}) }}
      </div>
  </div>
{{ form_end(form) }}

注册页面如下所示。

{% extends '::base.html.twig' %}
{% block body %}
    {% set tokens = app.session.get('registration') %}
    {% if tokens['firstName'] is defined %}
        {% set firstName = tokens['firstName'] %}
    {% endif %}
    {% if tokens['middleInit'] is defined %}
        {% set middleInit = tokens['middleInit'] %}
    {% endif %}
    {% if tokens['lastName'] is defined %}
        {% set lastName = tokens['lastName'] %}
    {% endif %}
    {% if tokens['email'] is defined %}
        {% set email = tokens['email'] %}
    {% endif %}
    {{ form_start(form) }}
    {{ form_errors(form) }}
    {{ form_label(form.firstName, 'First Name', {label_attr: {class: 'foo'}}) }}
    {% if firstName is defined %}
        {{ form_widget(form.firstName, { attr: {class: 'TestClass'}, value : firstName  }) }}
    {% else %}
        {{ form_widget(form.firstName, { attr: {class: 'TestClass'} }) }}
    {% endif %}
    {{ form_label(form.middleInitial) }}
    {% if middleInitial is defined %}
        {{ form_widget(form.middleInitial, { attr: {class: 'TestClass'}, value : middleInit }) }}
    {% else %}
        {{ form_widget(form.middleInitial, { attr: {class: 'TestClass'}}) }}
    {% endif %}
    {{ form_label(form.lastName) }}
    {% if lastName is defined %}
        {{ form_widget(form.lastName, { attr: {class: 'TestClass'}, value : lastName }) }}
    {% else %}
        {{ form_widget(form.lastName, { attr: {class: 'TestClass'}}) }}
    {% endif %}
    {{ form_label(form.email) }}
    {% if email is defined %}
        {{ form_widget(form.email, { attr: {class: 'TestClass'}, value : email }) }}
    {% else %}
        {{ form_widget(form.email, { attr: {class: 'TestClass'}}) }}
    {% endif %}
    {{ form_label(form.plainPassword.first) }}
    {{ form_widget(form.plainPassword.first) }}
    {{ form_label(form.plainPassword.second) }}
    {{ form_widget(form.plainPassword.second) }}
    <div>
        <input type="submit" value="{{ 'registration.submit'|trans }}"/>
    </div>
    {{ form_end(form) }}
{% endblock %}

希望这有帮助！
