Symfony2 - simplecms : how add extras data? - php

Question

I've a problem in my form for the entity Page from simplecms
I want to add an item in the array Extras, so i added it in my formtype :
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Cmf\Bundle\SimpleCmsBundle\Doctrine\Phpcr\Page;
class PageType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('title', 'text', array(
'label' => 'Titre',
'attr' => array('placeholder' => 'Titre complet de la page')
))
->add('name', 'text', array(
'label' => 'Label',
'attr' => array('placeholder' => 'nom-simplifie-de-la-page')
))
->add('body', 'ckeditor')
->add('locale', 'hidden')
->add('publishable')
->add('extras_link','text', array(
'property_path' =>"extras['link']",
));
}
The vars are in class Page (i didnt had to override it) and functions removeExtra() and addExtra() too (necessary to my form alimentation)
/**
* Add a single key - value pair to extras
*
* #param string $key
* #param string $value - if this is not a string it is cast to one
*/
public function addExtra($key, $value)
{
$this->extras[$key] = (string) $value;
}
/**
* Remove a single key - value pair from extras, if it was set.
*
* #param string $key
*/
public function removeExtra($key)
{
if (array_key_exists($key, $this->extras)) {
unset($this->extras[$key]);
}
}
form is working, but when i submit, it find removeExtra() but not addExtra()
"Found the public method "removeExtra()", but did not find a public "addExtra()" on class Symfony\Cmf\Bundle\SimpleCmsBundle\Doctrine\Phpcr\Page"
Somebody already had this problem? or know how to add data in extras?
THX (sorry for my english)

This is a limitation of the form layer unfortunately. The logic that looks for the right method only finds a adder with one parameter. What we ended up doing is using the burgov/key-value-form-bundle : https://github.com/Burgov/KeyValueFormBundle/
This required a PR like this to enabled in SeoBundle: https://github.com/symfony-cmf/SeoBundle/pull/158
from the code in Page::setExtras i think this should already work, though a similar PR to the one on SeoBundle would make it slightly more efficient.
