Symfony 2 添加动态表单;来自数据库的值

Symfony 2 add dynamic form; values from database

我想创建一个 google 类别匹配(来自数据库的第一个字段类别和第二个字段来自 google 类别的用户自动完成字段)表单,其中我有一个实体 CategoriesConfig :

 private $id;

/**
 * @var string
 *
 * @ORM\Column(name="category_site", type="string", length=100)
 */
private $categorySite;

/**
 * @var string
 *
 * @ORM\Column(name="category_google", type="string", length=100)
 */
private $categoryGoogle;

在我的控制器中,我尝试了这个

 /**
 * @Route("/adminDashboard/categoriesMatching", name="googleShopping_categories")
 * @Security("has_role('ROLE_SUPER_ADMIN')")
 */
public function categoriesMatchingAction(Request $request)
{
    // create a task and give it some dummy data for this example
    $idSite = $this->get('session')->get('_defaultWebSite')->getId();
    $categories = $this->getDoctrine()->getRepository('DataSiteBundle:SiteCategory')->findBy(array('IdSite' => $idSite));;
    $categories_config = new CategoriesConfig();
    //var_dump($categories);exit;
    $form = $this->createForm(new CategoriesConfigType($categories), $categories_config);


    return $this->render('GoogleShoppingBundle:Default:categoriesMatching.html.twig', array(
        'form' => $form->createView()
    ));
}

我的表单类型:CategoriesConfigType:

    class CategoriesConfigType extends AbstractType
    {
    /**
     * @param FormBuilderInterface $builder
     * @param array $options
     */
    private $site_categories;

     public function __construct ($site_categories) {
        $this->site_categories = $site_categories;
    }
    public function buildForm(FormBuilderInterface $builder, array $options)
    {   
        foreach($this->site_categories as $k => $categorie){
            $builder
                ->add('categorySite')
                ->add('categoryGoogle');
        }
    }

    /**
     * @param OptionsResolver $resolver
     */
    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'Sp\GoogleShoppingBundle\Entity\CategoriesConfig'
        ));
    }
  }

我希望类别行与行字段一样多(网站 itecategorie 和 google 类别)

结果是这样的:

提前致谢!

你在$this->categories上的循环是无效的,因为你每次添加的元素都具有相同的名称(categorySitecategoryGoogle),所以FormBuilder每次都会替换表单字段,而不是再添加一个。

但是,如果您希望表单处理 CategoryConfig 集合,则需要采用不同的方法。

1) 创建一个 CategoriesConfigType(如您所做),但谁只负责 一个 CategoriesConfig 实体

class CategoriesConfigType extends AbstractType
{     
    public function buildForm(FormBuilderInterface $builder, array $options)
    {   
        $builder
            ->add('categorySite')
            ->add('categoryGoogle');
    }

    /**
     * @param OptionsResolver $resolver
     */
    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'Sp\GoogleShoppingBundle\Entity\CategoriesConfig'
        ));
    }
}

2) 然后使用 CollectionType field 将您的表单作为整个 CategoryConfigTypes 集合进行操作:

class YourCollectionType extends AbstractType
{     
    public function buildForm(FormBuilderInterface $builder, array $options)
    {   
        $builder->add('categoriesConfigs', CollectionType::class, array(
            'entry_type'   => CategoriesConfigType::class,
            'entry_options'  => array('required'  => false)
        );
    }
}
