Question

我有两个实体，产品和功能（例如：宽度，高度，构图......）和另一个中间实体 ProductFeature 两个其他实体之间的关系。

我想在添加新产品时显示表单中的所有功能：

form

table

当我们在 PrestaShop 中添加新产品时，它看起来有点像。我试图使用该集合，但我失败了。

ProductType

class ProductType extends AbstractType
{

public function buildForm(FormBuilderInterface $builder, array $options)
{

    $builder
        //.....
        ->add('productFeatures', 'collection', array(
        'type' => new ProductFeatureType(),
        ))
    ;
}

public function setDefaultOptions(OptionsResolverInterface $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => 'Project\StoreBundle\Entity\Product'
    ));
}

}

ProductFeatureType

class ProductFeatureType extends AbstractType
{

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('value', 'text');
}

public function setDefaultOptions(OptionsResolverInterface $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => 'Project\StoreBundle\Entity\ProductFeature'
    ));
}

}

类型特征

class FeatureType extends AbstractType
{

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('name', 'text', array(
         'required' => true,
         'label' => 'Feature',
         'attr' => array('class' =>'form-control'),
         ))
    ;
}

public function setDefaultOptions(OptionsResolverInterface $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => 'Project\StoreBundle\Entity\Feature'
    ));
}


}

form.html.twig

                    {% for feature in form.productFeatures %}
                        <div class="form-group">
                            {{ form_label(form.feature, null, { 'label_attr': {'class': 'col-sm-3 control-label'} }) }}
                            <div class="col-sm-7">

                            {{ form_row(feature.name) }}

                            </div>
                            {{ form_errors(form.feature) }}
                        </div>
                    {% endfor %}
