所以我无法从子表单中获取属性。场景是我制作了一个工作表，其中选择了“雇主”。如果用户是应用程序管理员，他们可以选择所有雇主。如果用户是与多个雇主一起工作的工人，他们会在表单中选择雇主。否则（如果他们有一个雇主），我想用雇主集渲染一个隐藏字段。此外，Employer 子表单应自行处理此问题。

我的策略是在雇主子表单中设置一些属性，但是当我将这些属性添加到工作表单时，它们并没有通过（特别是“价值”）。

有谁知道我如何传播这些属性？

EmployerType（子表单）

<?php

namespace Agency\Work\WorkBundle\FormType;

use Agency\Work\WorkBundle\Transformer\EmployerTransformer;
use Agency\Work\WorkBundle\Transformer\SnowflakeTransformer;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;

class EmployerType extends AbstractType
{

    private $options;
    private $usor;
    private $single;
    private $biller;

    // public function __construct($usor) {
    //     $this->usor=$usor;
    public function __construct( array $options=array() ) {
        $this->usor=$options['usor'];
        $this->em=$options['em'];
        $this->single= ( 1 == $this->usor->getEmployer()->count() );
    }

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

        $builder->create( 'employer'
            , 'entity'
            , array(
                'class'        => 'Agency\Work\WorkBundle\Entity\Employer'
                , 'query_builder' =>
                function ( $repository ) {
                    $qb = $repository->createQueryBuilder( 'b' )
                    ->addOrderBy( 'b.name' );
                    if ( ! $this->usor->isAdmin() ) {
                        $qb->join( 'b.usor', 'u' )->andWhere( "u=$this->usor" );
                    }
                    return $qb;
                }
            )
        )
        ;

        if ($this->single) {
            $builder->setOption('data'
                , $this->single?( $this->usor->getEmployer()->first()->getId() ):''
                );
            $transformer=new EmployerTransformer( $this->em );
            $builder->addModelTransformer($transformer);
        }

        var_dump($builder->getOptions());
    }

    /**

     *
     * @param object  $resolver
     */
    public function setDefaultOptions( OptionsResolverInterface $resolver ) {
        $resolver->setDefaults( array(
                'class'        => 'Agency\Work\WorkBundle\Entity\Employer'
                , 'label'      => 'Employer'
                , 'label_attr' => array( 'class' => 'txtl' )
            ) );
    }

    public function getParent() {
        return $this->single ? 'hidden' : 'entity';
    }

    /**
     *
     *
     * @return unknown
     */
    public function getName() {

        return 'employer';
    }

}

WorkType（子表单）

<?php

namespace Agency\Work\WorkBundle\FormType;

use Agency\Work\WorkBundle\Transformer\EmployerTransformer;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;

class WorkType extends AbstractType
{

    public function buildForm( FormBuilderInterface $builder, array $options ) {
        $securityContext = $options['attr']['securitycontext'];
        if ( isset( $options['attr']['em'] ) ) { $em = $options['attr']['em'];} else {$em=null;}
        $usor    = $securityContext->getToken()->getUser();

        $builder->add(
            $builder->create ( 'employer'
                , new EmployerType( array( 'usor' => $usor, 'em'=>$em ) )
            )
            )
            ;


        $builder
        ->add( 'workDate'
            , null
            , array(
                'label'      => 'End'
                , 'label_attr' => array( 'class' => 'txtl' )
                , 'attr'       => array( 'class' => 'dateEnd' )
            )
        );

    }


    /**
     *
     *
     * @param object  $resolver
     */
    public function setDefaultOptions( OptionsResolverInterface $resolver ) {
        $resolver->setDefaults( array(
                'data_class' => 'Agency\Work\WorkBundle\Entity\Consent'
            ) );
    }


    /**
     *
     *
     * @return unknown
     */
    public function getName() {
        return 'jobtype';
    }


}

非常有趣的代码格式，但很难阅读。乍一看似乎是这里的错误

'query_builder' =>
                function ( $repository ) {
                    $qb = $repository->createQueryBuilder( 'b' )
                    ->addOrderBy( 'b.name' );
                    if ( ! $this->usor->isAdmin() ) {
                        $qb->join( 'b.usor', 'u' )->andWhere( "u=$this->usor" );
                    }
                    return $qb;
                }

您使用闭包作为回调函数，因此需要使用use关键字为闭包提供上下文。

'query_builder' => function ( $repository ) use ($usor) {
    $qb = $repository
        ->createQueryBuilder( 'b' )
        ->addOrderBy( 'b.name' );
    if ( ! $usor->isAdmin() ) {
        $qb->andWhere('b.usor = :u')->setParameter('u', $usor);
    }
    return $qb;
}
