In my symfony2 application, I have an attribute of type json_array :
/**
* @ORM\Column(name="rights", type="json_array", nullable=true)
*/
protected $rights = array();
The data for this attributeis an associative array as follows :
$allRights = array(
Associate::READ_PROFILE => array('all' => false),
Associate::UPDATE_PROFILE => array('all' => false),
Associate::READ_CONTACT => array('all', 'created' => false),
);
I want to be able to edit this attribute with a collection of checkboxes collections ie. I want one line per key of the first level and then one checkbox per key of the second level.
I have starter a form type which calls a custom type :
<?php
namespace AppBundle\Form\User;
use AppBundle\Entity\User\Associate;
use AppBundle\Form\DataTransformer\RightsToArrayTransformer;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\Form\FormEvent;
use Symfony\Component\Form\FormEvents;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
use Symfony\Component\Validator\Constraints as Assert;
class AssociateRightsType extends AbstractType
{
/**
* @param FormBuilderInterface $builder
* @param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('rights', 'fmu_rights', array(
'label' => false,
));
}
/**
* @param OptionsResolverInterface $resolver
*/
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'AppBundle\Entity\User\Associate',
'validation_groups' => array('Default', 'rights'),
'cascade_validation' => true,
));
}
/**
* @return string
*/
public function getName()
{
return 'appbundle_user_associate_rights';
}
}
In this custom type I have added a dataTransformer :
<?php
namespace AppBundle\Form\Type;
use AppBundle\Application\User\AssociateManager;
use AppBundle\Entity\User\Associate;
use AppBundle\Form\DataTransformer\RightsToArrayTransformer;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\Form\FormInterface;
use Symfony\Component\Form\FormView;
use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
class RightsType extends AbstractType
{
/**
* @var AssociateManager
*/
private $associateManager;
public function __construct(AssociateManager $associateManager)
{
$this->associateManager = $associateManager;
}
/**
* @param FormBuilderInterface $builder
* @param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$transformer = new RightsToArrayTransformer();
$builder->addModelTransformer($transformer);
}
/**
* @return string
*/
public function getName()
{
return 'fmu_rights';
}
}
In this data transformer I make sure the data is ouputed in the right format :
<?php
namespace AppBundle\Form\DataTransformer;
use AppBundle\Entity\User\Associate;
use Symfony\Component\Form\DataTransformerInterface;
class RightsToArrayTransformer implements DataTransformerInterface
{
/**
* @param mixed $data
* @return array|mixed
*/
public function transform($data)
{
return is_array($data) ? $data + $this->getRights() : $this->getRights();
}
/**
* @param mixed $data
* @return array
*/
public function reverseTransform($data)
{
return $data;
}
private function getRights()
{
$allRights = array(
Associate::READ_PROFILE => array('all'),
Associate::UPDATE_PROFILE => array('all'),
Associate::READ_CONTACT => array('all', 'created'),
Associate::UPDATE_CONTACT => array('all', 'created'),
Associate::DELETE_CONTACT => array('all', 'created'),
Associate::IS_BOSS => array('all'),
);
foreach ($allRights as $right => $parameters) {
$allRights[$right] = array();
foreach ($parameters as $parameter) {
$allRights[$right][$parameter] = false;
}
}
return $allRights;
}
}
and I have a custom view that makes the right visual ouput :
{% block fmu_rights_widget %}
{% if attr.class is defined %}
{% set attr = attr|merge({'class': attr.class ~ ' input-sm form-control fmu_rights'}) %}
{% endif %}
{% set rights = form.vars.data %}
{% for right, parameters in rights %}
<div class="row padding-v">
<div class="col-md-2">
{{ right }}
</div>
<div class="col-md-10">
{% for parameter, value in parameters %}
{% set name = id ~ '[' ~ loop.index ~ ']' ~ right ~ '[' ~ parameter ~ ']' %}
<label for="{{ name }}">{{ parameter }}</label>
<input type="checkbox" id="{{ name }}" name="{{ name }}" {% if value %}checked{% endif %}>
{% endfor %}
</div>
</div>
{% endfor %}
{% endblock %}
However, the data returned when I send my form is the original data output, not the modified data. I guess I've done it wrong in the view. How can I edit this data correctly and be able to manipulate it the reverse transform function of my data transformer ?
