Symfony搜索框问题

我在使用Symfony和Doctrine制作搜索框时遇到了问题。我使用2.8版本的Symfony。

我的问题是:

  

EntityManager#persist()期望参数1是一个实体对象,给定数组。 500内部服务器错误 - ORMInvalidArgumentException

所以,这是我的搜索框类型的类型:

/**
 * {@inheritdoc}
 */
public function buildForm(FormBuilderInterface $builder, array $options)  {

    $builder->add('searchBox',SearchType::class,array('label'=>'Vous cherchez : Un auteur ? Un éditeur ? Un ouvrage ?','attr'=>array('class'=>'form-control')));

}

/**
 * {@inheritdoc}
 */
public function configureOptions(OptionsResolver $resolver)
{
    $resolver->setDefaults(array(
        'data_class1' => 'SB\MainBundle\Entity\Ouvrages',
        'data_class2' => 'SB\MainBundle\Entity\Auteurs',
        'data_class3' => 'SB\MainBundle\Entity\Editeurs'
    ));
}

编辑后这是我的控制器代码:

public function indexAction(Request $request) {
    $ouvragesVentes = $this->getDoctrine()->getRepository('SBMainBundle:Ouvrages')->getOuvragesVentes();
    $ouvragesEchanges = $this->getDoctrine()->getRepository('SBMainBundle:Ouvrages')->getOuvragesEchanges();
    $categories = $this->getDoctrine()->getRepository('SBMainBundle:Categories')->getAllCats();

    $form = $this->createForm(SearchBoxType::class);
    $form->handleRequest($request);

    if ($form->isSubmitted() && $form->isValid()) {

        $searchBoxValue = $form->getData();

        $bookName = $this->getDoctrine()->getRepository('SBMainBundle:Ouvrages')->getOuvrageName($searchBoxValue);
        $editorName = $this->getDoctrine()->getRepository('SBMainBundle:Editeurs')->getEditeurName($searchBoxValue);
        $autorName = $this->getDoctrine()->getRepository('SBMainBundle:Auteurs')->getAuteurName($searchBoxValue);

        //if author
        if ($searchBoxValue == $autorName){
            return $this->redirect($this->generateUrl('sb_main_auteur'));
        }
        //if editor
        if ($searchBoxValue == $editorName){
            return $this->redirect($this->generateUrl('sb_main_editeur'));
        }
        //if book name
        if ($searchBoxValue == $bookName){
            return $this->redirect($this->generateUrl('sb_main_ouvrage'));
        }
    }

    $datas = array('categories'=>$categories,'form'=>$form->createView(),'ouvragesEchanges'=>$ouvragesEchanges,'ouvragesVentes'=>$ouvragesVentes);
    return $this->render('SBMainBundle:Main:index.html.twig',$datas);
}

编辑:我的formHandler

    protected $request;
protected $form;
protected $em;


//faire une injection de dépendance avec Request,Manager,Form(Objet)
public function __construct(Request $request,EntityManager $em, Form $form){
    $this->request = $request;
    $this->em = $em;
    $this->form = $form;
}

//vérifie si le formulaire est soumis et valide
public function process(){

    if ($this->request->getMethod() == "POST"){
        //récupération des données de la requête de la superglobale $_POST
        $this->form->handleRequest($this->request);
        //si ok, on appel onSuccess()
        if ($this->form->isValid()){
            $this->onSuccess($this->form->getData());
            return true;
        }
    }
    return false;

}

//si formulaire soumis et valide, on presiste l'objet (enregistre dans la DB)
public function onSuccess($object){
    //on persiste dans la DB via le manager Doctrine
    $this->em->persist($object);
    $this->em->flush();
}

我看here,但我认为不是我的问题的解决方案。然后,有人可以告诉我有什么问题?即使使用搜索框,我是否还需要搜索框实体?

感谢您的帮助!

新编辑:

  

缺少一些必需参数(“titreOuvrage”)来生成路由“sb_main_ouvrage”的URL。

sb_main_ouvrage:
path:     /ouvrage/{titreOuvrage}
defaults: { _controller: SBMainBundle:Main:ouvrage}

我的控制器用于映射页面:

    public function ouvrageAction(Ouvrages $ouvrages){
    $ouvrage =  $ouvrages->getTitreOuvrage();
    $categories = $this->getDoctrine()->getRepository('SBMainBundle:Categories')->getAllCats();
    $ouvragesVentes = $this->getDoctrine()->getRepository('SBMainBundle:Ouvrages')->getOuvragesVentesByName($ouvrage);
    $ouvragesEchanges = $this->getDoctrine()->getRepository('SBMainBundle:Ouvrages')->getOuvragesEchangesByName($ouvrage);
    $datas = array('ouvragesVentes'=>$ouvragesVentes,'ouvragesEchanges'=>$ouvragesEchanges,'categories'=>$categories,'ouvrages'=>$ouvrages);
    return $this->render('SBMainBundle:Main:ouvrage.html.twig',$datas);
}

答案 0 :(得分:0)

您的表单没有实体(或多个),这意味着您的$ form-> getData()将返回一个数组。并且,正如错误所示,您无法将数组传递给persist()方法。

如果您的目标是保存数据库中发送的每个搜索,您需要创建一个实体SearchBox(或任何您想要调用它),并相应地设置data_class。

如果您不想存储搜索,则无需调用处理程序。 (因为它除了调用一个persist()之外什么都不做) 而且您不需要实体check how to handle the submit without data_class

顺便说一下。在您的处理程序中,您调用$ form-> isValid()而不使用$ form-> isSubmitted()和此代码

if ($formHandler->process()){
    return $this->redirect($this->generateUrl(''));
}

if ($form->isSubmitted() && $form->isValid()) {
// You will never come here, because $formHandler->process() will return true if your form is valid, and leave your indexAction
}

希望它可以帮助你。

修改

您传递到存储库的数据是

$searchBoxValue = $form->getData();

这会将标记searchBoxValue作为数组返回,因为您要求提供所有表单数据。

但你想要的是获取特定的搜索字段数据,你需要做什么

$searchBoxValue = $form->get('searchBox')->getData();

请注意,我建议使用queryBuilder,或者至少保护您的查询免受sql注入。

e.g

public function getOuvrageName($titre){
    $query = $this->getEntityManager()->createQuery(
        "SELECT o FROM SBMainBundle:Ouvrages o WHERE o.titreOuvrage = :titre ORDER BY o.id DESC "
    )
    ->setParameter('titre', $titre);
    return $query->getResult();
}
