Symfony2 form in base.html.twig - symfony

Question

I am new to Symfony2 and I am just trying some stuff to learn Symfony2.
Currently, I have a few controllers which can perfrom some simple tasks. A simple crud controller for example.
Al my pages extend a base.html.twig file and insert their block into it. Now I want to add a login part to my base file, because I want to be able to login at every page. I was thinking to use the formbuilder for this, but this is php code which can not be in a html.twig file. I have absolutly no idea how to handle this. Can someone push me in the right direction of give my some working example?
Thanking in advance
Actions:
public function loginFormAction(Request $request){
// create a task and give it some dummy data for this example
$message = "";
$account = new Account();
$account->setEmail('login#login.nl');
$form = $this->createFormBuilder($account)
->add('email', 'text')
->add('wachtwoord', 'text')
->add('login', 'submit')
->getForm();
$form->handleRequest($request);
if ($_POST != null && $_POST['form']['email'] != null) {
$repository = $this->getDoctrine()->getRepository('AcmeBlogBundle:Account');
$email =$_POST['form']['email'];
$wachtwoord =$_POST['form']['wachtwoord'];
$foundAccount = $repository->findOneByemail($email);
if (!$foundAccount) {
$message = "Ingevuld email en wachtwoord komen niet overeen.";
}else if($foundAccount->getWachtwoord() == $wachtwoord){
$session = $request->getSession();
$session->set('name', $foundAccount->getVoornaam() . " " . $foundAccount->getAchternaam());
$session->set('email', $foundAccount->getEmail());
//return $this->redirect($this->generateUrl('melding', array('melding' => 'mooiman')));
//return $this->render('AcmeBlogBundle:Account:melding.html.twig', array('melding' => 'Hallo, '.$foundAccount->getVoornaam() . " " . $foundAccount->getAchternaam()));
$message = 'Hallo, '.$foundAccount->getVoornaam() . " " . $foundAccount->getAchternaam();
$form = $this->createFormBuilder()
->add('logout', 'submit')
->getForm();
return $this->render('AcmeBlogBundle:Account:login.html.twig', array('form'=> $form->createView(), 'message' => $message));
}else{
$message = "Ingevuld email en wachtwoord komen niet overeen.";
}
}
return $this->render('AcmeBlogBundle:Account:login.html.twig', array('form'=> $form->createView(), 'message' => $message));
}
public function logoutFormAction(Request $request){
// create a task and give it some dummy data for this example
$session = $request->getSession();
$message = 'Hallo, '.$session->get('name');
$form = $this->createFormBuilder()
->add('logout', 'submit')
->getForm();
$form->handleRequest($request);
if ($_POST != null) {
$account = new Account();
$account->setEmail('login#login.nl');
$form = $this->createFormBuilder($account)
->add('email', 'text')
->add('wachtwoord', 'text')
->add('login', 'submit')
->getForm();
$session->set('name', null);
$session->set('email', null);
$message = "U bent nu uitgelogd";
}
return $this->render('AcmeBlogBundle:Account:login.html.twig', array('form'=> $form->createView(), 'message' => $message));
}
Base.html.twig:
{% if(app.session.get('name') == null) %}
{{ render(controller('AcmeBlogBundle:Account:loginForm')) }}
{% else %}
{{ render(controller('AcmeBlogBundle:Account:logoutForm')) }}
{% endif %}

Answer 1

You can include whole output of other controller/action in template. Just include this in your taplate:
<div id="sidebar">
{{ render(controller('YourBundle:User:login')) }}
</div>
This will inject whole output of YourBundle/UserController/loginAction to the #sidebar div. Remember that YourBundle/UserController/loginAction template can't extend other twig templates and hould be simple.
You can read more about embedding controllers here http://symfony.com/doc/current/book/templating.html#embedding-controllers
[EXAMPLE]:
An form action:
/**
* #Route("/contact", name="contact")
*/
public function contactAction(Request $request){
$form = $this->createFormBuilder()
->setAction($this->generateUrl('contact'))
->add('email', 'email', array(
'constraints' => array(
new \Symfony\Component\Validator\Constraints\Email()
)
))
->add('add', 'submit')
->getForm()
;
if ($request->getMethod() == 'POST') {
$form->handleRequest($request);
if ($form->isValid()) {
//do whatever you want and redirect
return $this->redirect($this->generateUrl('homepage'));
}else{
// this must be a full page (extending from base tamplate)
// that show form and errors
return $this->render(
'YourBundle:ControllerName:contact_faild.html.twig',
array('form' => $form->createView())
);
}
}
return $this->render(
'YourBundle:ControllerName:contact.html.twig',
array('form' => $form->createView())
);
}
There must be action URL in form "->setAction($this->generateUrl('contact'))" because form should be handled on separate request.
Next a form template (YourBundle:ControllerName:contact.html.twig):
{{ form(form) }}
Then we need an extra template for showing form errors when something went wrong. That should extend base template and probably override place where form appear in the first time
A form with errors tempalte (YourBundle:ControllerName:contact_faild.html.twig):
{% extends '::base.html.twig' %}
{% block sidebar -%}
{{ form(form) }}
{% endblock sidebar %}
And base teplate:
(...)
{% block sidebar %}
<div id="sidebar">
{{ render(controller('ClickAdUserBundle:User:contact')) }}
</div>
{% endblock %}
(...)

read this
you will find some html/twig code, put that in a "login.html.twig" and include it where you want

Answer 3

If you're completly new to Symfony2 i can suggest the symfony2 symblock tutorial
You'll work with Doctrine 2, creating Forms and design them, Twig Layouts and all the other stuff while creating a little blog.
Taken from the example, you would create the form in your controller like this
// src/Blogger/BlogBundle/Controller/PageController.php
public function contactAction()
{
$enquiry = new Enquiry(); //This creates an Instance of the Entity you need for the form
$form = $this->createForm(new EnquiryType(), $enquiry);
$request = $this->getRequest();
if ($request->getMethod() == 'POST') {
$form->bindRequest($request);
if ($form->isValid()) {
// Perform some action, such as sending an email
// Redirect - This is important to prevent users re-posting
// the form if they refresh the page
return $this->redirect($this->generateUrl('BloggerBlogBundle_contact'));
}
}
return $this->render('BloggerBlogBundle:Page:contact.html.twig', array(
'form' => $form->createView()
));
}
and the form as .html.twig would look like this
{# src/Blogger/BlogBundle/Resources/views/Page/contact.html.twig #}
{% extends 'BloggerBlogBundle::layout.html.twig' %}
{% block title %}Contact{% endblock%}
{% block body %}
<header>
<h1>Contact symblog</h1>
</header>
<p>Want to contact symblog?</p>
<form action="{{ path('BloggerBlogBundle_contact') }}" method="post" {{ form_enctype(form) }} class="blogger">
{{ form_errors(form) }}
{{ form_row(form.name) }}
{{ form_row(form.email) }}
{{ form_row(form.subject) }}
{{ form_row(form.body) }}
{{ form_rest(form) }}
<input type="submit" value="Submit" />
</form>
{% endblock %}
I hardly suggest working through this tutorial to have a nice start with symfony2
