symfony 2 form input fields are not rendered - php

Question

I'm trying to create simple form but for some reason input fields are not rendered. The source code shows that the open and close tag of form are rendered but not the input fields itself.
Here is the code
namespace SDProjectBundle\Forms;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
class UserForm extends AbstractType
{
public function formBuilder(FormBuilderInterface $builder, array $options)
{
$builder->add('email', 'text')
->add('password', 'password')
->add('Send', 'submit');
}
public function getName()
{
return 'app_users';
}
}
namespace SDProjectBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\Request;
use SDProjectBundle\Forms\UserForm;
use SDProjectBundle\Entity\User;
class UsersController extends Controller
{
public function addAction(Request $request)
{
$form = $this->createForm(new UserForm(), new User());
return $this->render('SDProjectBundle:Users:add.html.twig', array(
'form' => $form->createView(),
));
}
}
add.html.twig
{{ form_start(form) }}
{{ form_widget(form) }}
{{ form_end(form) }}
What I'm doing wrong?

Answer 1

You implements the wrong method in the form class: you need to implements the buildForm method of your custom form type.
Practically, in the UserForm class, you need to put this:
public function buildForm(FormBuilderInterface $builder, array $options)
instead of
public function formBuilder(FormBuilderInterface $builder, array $options)
Hope this help

Answer 2

If you want to render the form component try with
{{ form_widget(form) }}
instead of
{{ form_label(form) }}
If you want to render only the label of the field you need to specify the field as:
{{ form_label(form.email) }}
A complete manually rendered version of your form can be:
{{ form_start(form) }}
{{ form_errors(form) }}
<div>
{{ form_label(form.email) }}
{{ form_errors(form.email) }}
{{ form_widget(form.email) }}
</div>
<div>
{{ form_label(form. password) }}
{{ form_errors(form. password) }}
{{ form_widget(form. password) }}
</div>
<div>
{{ form_widget(form. Send) }}
</div>
{{ form_end(form) }}

Try this in your TWIG:
{% block form_row %}
{% spaceless %}
<div class="form-group">
{{ form_label(form) }}
<div>
{{ form_widget(form) }}
</div>
</div>
{% endspaceless %}
{% endblock form_row %}
