Show input in embedded form in symfony2 - php

Question

I'm trying to create an embedded form in symfony2 that will consist of a Contact form that will have embedded a ContactPhonenumber form to add phone numbers.
I have followed the instructions in Symfony2 documentation about embedding forms but I can't find a way to show at least an input field for phonenumbers. If I do it without errors, I only get back a label for the embedded phonenumber form.
How can I show an input there?
My code is:
My two entity form classes:
class ContactType extends AbstractType
{
/**
* #param FormBuilderInterface $builder
* #param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('contactType')
->add('title')
->add('name')
->add('givenName')
->add('middleName')
/*->add(
'contactPhonenumbers',
'collection',
array( 'type' => new ContactPhonenumberType($options) )
)
*/
->add('contactPhonenumbers', new ContactPhonenumberType($options) )
;
}
//.......
//More functions
//.......
}
class ContactPhonenumberType extends AbstractType
{
public function __construct(array $options=null) {
$this->options = $options;
}
/**
* #param FormBuilderInterface $builder
* #param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('position')
->add('number')
->add(
$builder->create(
'contact',
'searchable',
array(
'data_class' => '....Bundle\Entity\Contact',
'class' => '....Bundle:Contact',
'dataroute' => '...._contact_searchable',
'classlistview' => new ....Bundle\Component\Listview\ContactList
)
)->addViewTransformer(
new NameToIdTransformer(
$options[ 'em' ],
$options[ 'request' ],
$this,
array(),
'....Bundle:Contact'
)
)
)
->add(
$builder->create(
'phonenumberType',
'searchable',
array(
'data_class' => '....Bundle\Entity\PhonenumberType',
'class' => '.....Bundle:PhonenumberType',
'dataroute' => '...._phonenumbertype_searchable',
'classlistview' => new ....\Component\Listview\PhonenumberTypeList
)
)->addViewTransformer(
new NameToIdTransformer(
$options[ 'em' ],
$options[ 'request' ],
$this,
array(),
'...Bundle:PhonenumberType'
)
)
)
;
}
}
And my function on controller
public function newAction( Request $request )
{
$em = $this->getDoctrine()->getManager();
$entity = new Contact();
// $number = new ArrayCollection();
// $number[] = new ContactPhonenumber();
// $entity->setContactPhonenumbers( $number );
$form = $this->createCreateForm( $entity );
return $this->render(
'...Bundle:Contact:new.html.twig',
array(
'entity' => $entity,
'form' => $form->createView()
)
);
}
And the form in twig:
<div class="widget-body">
{{ form_start( form, { 'attr': { 'class': 'form-horizontal', 'role': 'form', 'novalidate': 'novalidate' } } ) }}
{{ form_errors( form ) }}
{{ form_row( form.contactType ) }}
{{ form_row( form.title ) }}
{{ form_row( form.name ) }}
{{ form_row( form.givenName ) }}
{{ form_row( form.middleName ) }}
------>
{{ form_row(form.contactPhonenumbers) }}
<--------
{{ form_row( form.salutation ) }}
{{ form_row( form.address ) }}
{{ form_row( form.superiorContact ) }}
<div class="form-group">
<hr>
</div>
<div class="form-group">
<div class="col-sm-2"></div>
<div class="col-sm-10">
{{ form_widget( form.submit ) }}
{{ form_widget( form.cancel ) }}
</div>
</div>
{{ form_row( form._token ) }}
{{ form_end( form, { 'render_rest': false } ) }}
