我正在使用Symfony 2.8
我在用户和扇区实体之间有很多与许多关系，插入效果很好，但是编辑表单（编辑表格函数）的创建不起作用。所有代码都在那里：

我会收到错误，说：
类型错误：参数2传递给UserBundle form type prifileaBoutMeformType :: UserBundle form form form type type {clocture}（）必须是教义 common common collections collections collections arraycollection arraycollection，of doctrine orm orm orm orm orm orm orm orm orm orm orm ，in/src/userbundle/form/type/profileaboutmeformtype.php in 383
我应该更改getectors方法以持久汇总吗？或者我需要完全改变我的方法？
所以，是的，基本上回答了我自己的问题。我为这种方法提供了自己的解决方案。我必须更改"编辑表单"的EventListener。
正如我通过存储库查询数据库时所了解的，您会得到 持久票据以及与实体合作时，您会得到 ArrayCollection
我已将 Doctrine common collections arrayCollection $ sector作为$ formmodify函数中的数组$ sector。另外，我也在pre_set_data和postrongubmit事件中更改。
以下是更改事件侦听器的完整代码。
$factory = $builder->getFormFactory();
$formModify = function (FormInterface $form, array $sector, $factory) {
$output = [];
foreach($sector as $sec) {
$output[] = $sec;
}
$formOption = array(
'class' => 'CocoricoUserBundleEntityUserAccreditation',
'multiple' => true,
'auto_initialize' => false,
'required' => false,
'expanded' => true,
'label' => 'Accreditations',
'choice_attr' => function ($output) {
return ['class' => 'attr_checkbox'];
},
'query_builder' => function(EntityRepository $ertt) use ($output) {
// build a custom query, or call a method on your repository (even better!)
$qb = $ertt->createQueryBuilder('g');
$qb->select(array('g'));
$qb->where('g.sector IN (:sector_id)');
$qb->setParameters( array('sector_id' => $output) );
$qb->orderBy('g.name', 'ASC');
return $qb;
},
);
$form->add($factory->createNamed('accreditationdata', EntityType::class, null, $formOption));
};
$builder->addEventListener(FormEvents::PRE_SET_DATA,function (FormEvent $event) use ($formModify,$factory) {
$data = $event->getData();
$form = $event->getForm();
if ($data != null)
$newarray = [];
foreach ($data->getSectors() as $post) {
// $post is not an array
$newarray[] = $post->id;
}
$formModify($event->getForm(), $newarray,$factory);
}
);
$factory = $builder->getFormFactory();
$builder->get('sectors')->addEventListener(FormEvents::POST_SUBMIT,function (FormEvent $event) use ($formModify,$factory) {
$sector = $event->getForm()->getData();
$created_array = array($sector->getId());
$array = [];
foreach($created_array as $secval) {
$array[] = $secval;
}
$formModify($event->getForm()->getParent(), $array,$factory);
}
);
这对我有用。希望它可以帮助其他人采用这种类型的方法。
