我遇到了Symfony 2.5的一些问题我需要基于我从控制器传递的一些参数来修改表单，但我无法初始化$ options数组到任务。
我的文件：
// ordersContrroller.php $orders=new OrdersM(); $form = $this->createForm(new ListOrdersType(), $orders, array('id'=>1)); // ListOrdersType.php use Symfony\Component\Form\AbstractType; use Symfony\Component\Form\FormBuilderInterface; use Symfony\Component\Form\FormEvent; use Symfony\Component\Form\Event\DataEvent; use Symfony\Component\Form\FormEvents; use Doctrine\ORM\EntityRepository; use Symfony\Component\OptionsResolver\OptionsResolverInterface; class ListOrdersType extends AbstractType { public function getDefaultOptions(OptionsResolverInterface $resolver) { $resolver->setDefaults(array( 'data_class' => 'Acme\MyBundle\Form\Model\OrdersM', 'id'=>1, )); } public function buildForm(FormBuilderInterface $builder, array $options) { var_dump(array_keys($options)); $builder->add('orders', 'entity', array( 'class' => 'AcmeMyBundle:Orders', 'property' => 'name', 'query_builder' => function($repository) use ($options) { return $repository->createQueryBuilder('o') ->where('o.id='.$options['id']) ->orderBy('o.id', 'ASC' ) ; } )); } public function getName() { return 'orders'; } }我有两个截然不同的问题。 当我把选项数组放在che控制器数组中时（'id'=> 1）
我发现以下错误：
选项“id”不存在。 已知选项包括：“action”，“attr”，“auto_initialize”，“block_name”，“by_reference”，“cascade_validation”，“compound”，“constraints”，“csrf_field_name”，“csrf_message”，“csrf_protection”，“csrf_provider” “，”csrf_token_id“，”csrf_token_manager“，”data“，”data_class“，”disabled“，”empty_data“，”error_bubbling“，”error_mapping“，”extra_fields_message“，”inherit_data“，”意图“，”invalid_message“， “invalid_message_parameters”，“label”，“label_attr”，“mapped”，“max_length”，“method”，“pattern”，“post_max_size_message”，“property_path”，“read_only”，“required”，“translation_domain”，“trim “，”validation_groups“，”虚拟“
就像声明解析器的默认选项时未声明选项一样。
当我尝试在query_builder函数上使用键$ option ['id']上的$ options数组时，我得到以下错误：
注意：未定义索引：**** / Form / Type / ListOrdersType.php第56行中的id
那个是这个：
->where('o.id='.$options['id'])id $选项是ony one，但我真的需要在EntityType.php文件中使用不同的参数进行查询，我真的需要以某种方式将它们传递给选项。
我错过了什么？ Tx适合您的时间。
I'm encountering some problem with Symfony 2.5 i've the need to dinamicaly modify a form based on some parameters that i've to pass from the controller but i cant initializate the $options array to the task.
My Files:
// ordersContrroller.php $orders=new OrdersM(); $form = $this->createForm(new ListOrdersType(), $orders, array('id'=>1)); // ListOrdersType.php use Symfony\Component\Form\AbstractType; use Symfony\Component\Form\FormBuilderInterface; use Symfony\Component\Form\FormEvent; use Symfony\Component\Form\Event\DataEvent; use Symfony\Component\Form\FormEvents; use Doctrine\ORM\EntityRepository; use Symfony\Component\OptionsResolver\OptionsResolverInterface; class ListOrdersType extends AbstractType { public function getDefaultOptions(OptionsResolverInterface $resolver) { $resolver->setDefaults(array( 'data_class' => 'Acme\MyBundle\Form\Model\OrdersM', 'id'=>1, )); } public function buildForm(FormBuilderInterface $builder, array $options) { var_dump(array_keys($options)); $builder->add('orders', 'entity', array( 'class' => 'AcmeMyBundle:Orders', 'property' => 'name', 'query_builder' => function($repository) use ($options) { return $repository->createQueryBuilder('o') ->where('o.id='.$options['id']) ->orderBy('o.id', 'ASC' ) ; } )); } public function getName() { return 'orders'; } }I've TWO distinct problems. When i put the options array in che controller array('id'=>1)
i recive the following error:
The option "id" does not exist. Known options are: "action", "attr", "auto_initialize", "block_name", "by_reference", "cascade_validation", "compound", "constraints", "csrf_field_name", "csrf_message", "csrf_protection", "csrf_provider", "csrf_token_id", "csrf_token_manager", "data", "data_class", "disabled", "empty_data", "error_bubbling", "error_mapping", "extra_fields_message", "inherit_data", "intention", "invalid_message", "invalid_message_parameters", "label", "label_attr", "mapped", "max_length", "method", "pattern", "post_max_size_message", "property_path", "read_only", "required", "translation_domain", "trim", "validation_groups", "virtual"
Like the option is not declared during the declaration of the defaults options of the resolver.
And ofcorse when i try to use the $options array on the key $option['id'] on the query_builder function i get the following error:
Notice: Undefined index: id in ****/Form/Type/ListOrdersType.php line 56
that ofc is this one:
->where('o.id='.$options['id'])The id $option is ony one , but i realy need to make my query in the EntityType.php files dinaic following differents parameters, i realy need to pass them over options in some way.
What i'm missing? Tx for your time.
最满意答案
尝试这样（ getDefaultOptions更改为setDefaultOptions ）：
class ListOrdersType extends AbstractType { public function setDefaultOptions(OptionsResolverInterface $resolver) { $resolver->setDefaults(array( 'data_class' => 'Acme\MyBundle\Form\Model\OrdersM', 'id'=> null, )); } public function buildForm(FormBuilderInterface $builder, array $options) { $builder->add('orders', 'entity', array( ... 'query_builder' => function($repository) use ($options) { return $repository->createQueryBuilder('o') ->where('o.id= :id') ->orderBy('o.id', 'ASC' ) ->setParameter('id', $options['id']) ; } )); } ... } $orders=new OrdersM(); $form = $this->createForm(new ListOrdersType(), $orders, array('id'=>1));Try like this (getDefaultOptions changed to setDefaultOptions):
class ListOrdersType extends AbstractType { public function setDefaultOptions(OptionsResolverInterface $resolver) { $resolver->setDefaults(array( 'data_class' => 'Acme\MyBundle\Form\Model\OrdersM', 'id'=> null, )); } public function buildForm(FormBuilderInterface $builder, array $options) { $builder->add('orders', 'entity', array( ... 'query_builder' => function($repository) use ($options) { return $repository->createQueryBuilder('o') ->where('o.id= :id') ->orderBy('o.id', 'ASC' ) ->setParameter('id', $options['id']) ; } )); } ... } $orders=new OrdersM(); $form = $this->createForm(new ListOrdersType(), $orders, array('id'=>1));更多推荐
