在我的symfony2应用程序中,我有一个json_array类型的属性:
/**
* @ORM\Column(name="rights", type="json_array", nullable=true)
*/
protected $rights = array();
此属性的数据是一个关联数组,如下所示:
$allRights = array(
Associate::READ_PROFILE => array('all' => false),
Associate::UPDATE_PROFILE => array('all' => false),
Associate::READ_CONTACT => array('all', 'created' => false),
);
我希望能够使用复选框集合来编辑此属性,即。我希望第一级每个键一行,然后第二级每个键一个复选框。
我有一个表单类型,它调用自定义类型:
<?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';
}
}
在这个自定义类型中,我添加了一个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';
}
}
在这个数据转换器中,我确保以正确的格式对数据进行加密:
<?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;
}
}
我有一个自定义视图,可以产生正确的视觉输出:
{% 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 %}
但是,发送表单时返回的数据是原始数据输出,而不是修改后的数据。 我想我在视图中做错了。如何正确编辑这些数据并能够将其数据变换器的反向变换功能操作?

你的问题是你正在创建一些symfony一无所知的输入字段(复选框)。事实上,当你提交表单时,它可能会抛出一个异常,说它收到了一些它没想到的字段。您需要将这些字段转换为symfony可以理解的内容。你可以用两种方式做到这一点:
