Question

在我的搜索过滤器 （FormBuilder）中返回过滤结果列表，我有一个与对象相关的表单（多个复选框）< / em>的。它不起作用。我认为我的存储库存在问题，无法获得数组与对象结果。

<?php namespace AdminBundle\Controller; use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route; use Symfony\Bundle\FrameworkBundle\Controller\Controller; use Symfony\Component\HttpFoundation\Response; use Symfony\Component\HttpFoundation\Request; use Symfony\Bridge\Doctrine\Form\Type\EntityType; use Symfony\Component\Form\Extension\Core\Type\EmailType; use Symfony\Component\Form\Extension\Core\Type\SubmitType; use Symfony\Component\Form\Extension\Core\Type\TextareaType; use Symfony\Component\Form\Extension\Core\Type\TextType; use Symfony\Component\Validator\Constraints as Assert; use AdminBundle\Entity\Products; use AdminBundle\Form\ProductsType; class ProductsController extends Controller { /** * @Route("/", name="homepage") */ public function indexAction(Request $request) { $form = $this->createFormBuilder() ->add('category', 'entity', array( 'class' => 'AdminBundle:Category', 'label' => false, 'choice_label' => 'name', 'required' => false, 'expanded' => true, 'placeholder' => 'Tous', 'multiple' => true )) // ... ;

这是我的存储库：

<?php namespace AdminBundle\Repository; class ProductsRepository extends \Doctrine\ORM\EntityRepository { public function ListAll($data) { $query = $this->createQueryBuilder('a')->orderBy('a.updated','DESC'); // CATEGORY if($data['category'] !== null) { $query ->innerJoin('a.category', 'cat') ->andWhere('cat.id = :catid') ->setParameter('catid', $data['category']) ; /* $query ->leftJoin('a.category', 'category') ->setParameter('category', $data['category']) ; */ } // ... } }

此存储库仅适用于单个选择：multiple => false。当我设置multiple => true时，我得到关于对象与数组的SQL违规。

如何处理多个复选框的存储库？

您必须使用ChoiceType而不是entityType

class CategoryRepository extends \Doctrine\ORM\EntityRepository
{
public function getForSearch()
{
    $qb = $this->createQueryBuilder('category');

    $qb->orderBy('category.name');
    $query = $qb->getQuery();

    $results = $query->getResult();
    $categories = array();

    foreach ($results as $category) {
        $categories[$category->getName()] = $category->getId();
    }

    return $categories;
}

表格

$categories = $em->getRepository(Category::class)->getForSearch();

 ->add('categories', ChoiceType::class, array(
            'choices' => $categories,
            'required' => false,
            'placeholder' => 'Select',
        ))

在控制器中：

if ($search_form->isSubmitted() && $search_form->isValid()) {
        $data = $search_form->getData();
        $em->getRepository(Product::class)->ListAll($data);

我也认为我们可以使用数据转换器，但我不知道如何做到这一点
