Partial User Registration on Home Page (index) - php

Question

I am using Symfony2 2.6.4 with the FOS User Bundle (master) and I am having a hard time trying to pass a partial registration from the home page to the registration page.
The Goal
I want a user to start on the home page and fill out some info and press submit. I want the user to be passed to the registration page and pre fill the items that they have already filled out on the front page.
Things I have tried:
I am unsure what is feasable and have already spend too much time on this. I tried extending the registration controller but I am getting errors before I can even start on my issue so I stopped. My last thought was to pass the variables in a session to the overridden registration form type and see if I can pre-populate it there.
Has anyone done anything like this before? They sure don't make it easy.

Credit goes to #NawfalSerrar Thank you for the idea. I was close but not close enough!
So what I ended up doing was this.
This is the controller action that does that work.
/**
* #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(),
));
}
Then the form on the front end.
{{ form_start(form,{'attr': {'class': 'reg-page'}}) }}
<div class="reg-header">
<h1>Get Started!</h1>
<p>Already Signed Up? Click Sign In 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) }}
Registration page looks like this.
{% 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 %}
Hope this helps!
