带参数的 symfony2 搜索表单查询生成器

Question

这是左侧页面的图片我在提交时有一个表格我希望它使用用户输入的信息在右侧显示找到的车辆如果用户不去表格页面显示所有汽车。在这两种情况下，用户应该只看到价格不为 0

的汽车

这是我的表格，以备不时之需，但我在这里没问题 VoitureType3.php :

$builder
->add('marque', EntityType::class,array(
        'class' => 'SpoiledCarFrontOfficeBundle:Marque',
        'required'      => true, 
        'empty_value'   => '== Choisissez une Marque ==',
         ))

       ->add('modele', DependentFormsType::class,array(
       'entity_alias'   => 'modele_by_marque',
       'parent_field'   => 'marque',
       'empty_value'    => '== Choisissez un Modele =='


         ))
    ->add('chevaux', 'choice', array( 'choices' => array('4' => '4', '5' => '5', '6' => '6', '7' => '7', '8' => '8', '9' => '9', '10' => '10', '11' => '11', '12' => '12', '13' => '13', '14' => '14', '15' => '15', '16' => '16'),'expanded' => false, 'required' => true,
     'multiple' => false,   'label' => 'Nombre de Chevaux' )) 
    ->add('boitevitesse', 'choice', array( 'choices' => array('Automatique' => 'Automatique', 'Manuelle' => 'Manuelle', 'Sequentielle' => 'Sequentielle'),'expanded' => false, 'required' => true,
     'multiple' => false,   'label' => 'Boite de Vitesse' ))       

这是我的控制器：

  $filterForm = $this->createForm('SpoiledCar\FrontOfficeBundle\Form\VoitureType3');

 $em = $this->getDoctrine()->getManager();
  $voiturefind = $em->getRepository('SpoiledCarFrontOfficeBundle:Voiture')->myFindAll($filterForm);
 $voitures  = $this->get('knp_paginator')->paginate($voiturefind,$this->get('request')->query->get('page', 1),6); 

// Bind values from the request
$filterForm->handleRequest($request);

 if ($filterForm->isSubmitted() && $filterForm->isValid()) {
  return $this->render('FOSUserBundle:Profile:listTable.html.twig', array(
        'voitures' => $voitures,


 ));
   }
   return $this->render('FOSUserBundle:Profile:listTable.html.twig', array(
        'voitures' => $voitures,
        'filterForm' => $filterForm->createView(),

  ));

我遇到了这个错误：

  Attempted to call an undefined method named "andWhere" of class "Doctrine\ORM\Query". 

这是我的查询生成器，我认为问题出在此处，但我不知道我到底做错了什么

public function myFindAll(FormInterface $filterForm)
{

  $qb = $this->createQueryBuilder('p')
    ->Where('p.prix IS NOT NULL')
    ->getQuery();
 if ($filterForm->has('marque')) {
 $qb->andWhere( $qb->expr()->like('u.marque', ':marque'))
  ->setParameter('marque', '%'. $filterForm->get('marque')->getData().'%');
  }
  if ($filterForm->has('modele')) {
 $qb->andWhere( $qb->expr()->like('u.modele', ':modele'))
 ->setParameter('modele', '%'. $filterForm->get('modele')->getData().'%');
  }

 if ($filterForm->has('boitevitesse')) {
 $qb->andWhere( $qb->expr()->like('u.boitevitesse', ':boitevitesse'))
->setParameter('boitevitesse', '%'. $filterForm->get('boitevitesse')- >getData().'%');
  }

 if ($filterForm->has('chevaux')) {
$qb->andWhere( $qb->expr()->like('u.chevaux', ':chevaux'))
->setParameter('chevaux', '%'. $filterForm->get('chevaux')->getData().'%');
}

return $qb->getResult();
}

Answer 1

在其余可选表达式之前调用 getQuery() 方法...

尝试 "move it" :

public function myFindAll(FormInterface $filterForm)
{
     $qb = $this->createQueryBuilder('p');

     /***/

     return $qb->getQuery()->getResult();
}
