该属性和方法都不存在，并在自定义类中有公共访问FieldType

问题描述：

我在我的symfony项目中添加了一个自定义的FieldTypeExtension。我想延长SubmitType中，SubmitTypeExtension.php样子：该属性和方法都不存在，并在自定义类中有公共访问FieldType

class SubmitTypeExtension extends AbstractTypeExtension 
{ 
    /** 
    * Returns the name of the type being extended. 
    * 
    * @return string The name of the type being extended 
    */ 
    public function getExtendedType() 
    { 
     return SubmitType::class; 
    } 

    public function configureOptions(OptionsResolver $resolver) 
    { 
     $resolver->setDefined(array('button_image','button_color')); 
    } 

    public function buildView(FormView $view, FormInterface $form, array $options) 
    { 
     if (isset($options['button_image'])) { 
      $parentData = $form->getParent()->getData(); 

      $buttonImage = null; 
      if (null !== $parentData) { 
       $accessor = PropertyAccess::createPropertyAccessor(); 
       $buttonImage = $accessor->getValue($parentData, $options['button_image']); 
      } 

      $view->vars['button_image'] = $buttonImage; 
     } 
     if (isset($options['button_color'])) { 
      $parentData = $form->getParent()->getData(); 

      $buttonColor = null; 
      if (null !== $parentData) { 
       $accessor = PropertyAccess::createPropertyAccessor(); 
       $buttonColor = $accessor->getValue($parentData, $options['button_color']); 
      } 

      $view->vars['button_color'] = $buttonColor; 
     } 
    } 
}

我称之为一个自定义类型的字段类型：

class VereinType extends AbstractType 
{ 
    public function buildForm(FormBuilderInterface $builder, array $options) 
    { 
     $builder 
      ->add('name', TextType::class) 
      ->add('save', SubmitType::class, array(
       'label' => 'Speichern', 
       'button_image' => 'check', 
       'button_color' => 'rgba(13, 135, 13, 1)' 
      )) 
     ; 
    } 

    public function configureOptions(OptionsResolver $resolver) 
    { 
     $resolver->setDefaults(array(
      'data_class' => 'TeilnehmerBundle\Entity\Verein', 
     )); 
    } 
}

我需要这个定制我的submitType用glyphicon。在services.yml我已经添加了服务

app.submit_type_extension: 
    class: TeilnehmerBundle\Form\Extension\SubmitTypeExtension 
    tags: 
     - { name: form.type_extension, extended_type: Symfony\Component\Form\Extension\Core\Type\SubmitType }

但现在我得到以下错误

Neither the property "check" nor one of the methods "getCheck()", "check()", "isCheck()", "hasCheck()", "__get()" exist and have public access in class "TeilnehmerBundle\Entity\Verein".

的问题是，我不能有任何财产

{% extends 'bootstrap_3_layout.html.twig' %} 

{%- block submit_widget -%} 
    {% set attr = attr|merge({class: (attr.class|default('btn-default') ~ ' btn btn-lg btn-sm')|trim}) %} 
    {%- if label is empty -%} 
     {%- if label_format is not empty -%} 
      {% set label = label_format|replace({ 
      '%name%': name, 
      '%id%': id, 
      }) %} 
     {%- else -%} 
      {% set label = name|humanize %} 
     {%- endif -%} 
    {%- endif -%} 
    <button type="{{ type|default('submit') }}" {{ block('button_attributes') }}><span class="glyphicon glyphicon-{{ button_image }}" aria-hidden="true" style="color: {{ button_color }};"></span><b>{{ translation_domain is same as(false) ? label : label|trans({}, translation_domain) }}</b></button> 
{%- endblock submit_widget -%}

就像我添加的两个，因为我只用它们来定制我的按钮。任何人都可以帮助我吗？

尝试添加'映射=> FALSE'在你的表单生成器？我认为，如果这些参数仅用于视图渲染，只需在表单构建器的'attr'下添加值并在模板构件（不带扩展名）中访问它们即可。 – ejuhjav

是的，但这不是按钮标签的属性。我必须在之间加上一些东西，并在表单构建器中使用'attr'，我只能在按钮标签中传递一些东西。当我在'label'中添加内容时，HTML代码被打印出来，并且不能被正确解释。 – user3296316

映射不是SubmitType :-( – user3296316

修改下面我SubmitTypeExtension：

class SubmitTypeExtension extends AbstractTypeExtension 
{ 
    /** 
    * Returns the name of the type being extended. 
    * 
    * @return string The name of the type being extended 
    */ 
    public function getExtendedType() 
    { 
     return SubmitType::class; 
    } 

    public function configureOptions(OptionsResolver $resolver) 
    { 
     $resolver->setDefined(array('button_image','button_color')); 
    } 

    public function buildView(FormView $view, FormInterface $form, array $options) 
    { 
     if(isset($options['button_image'])) 
      $view->vars['button_image'] = $options['button_image']; 
     else 
      $view->vars['button_image'] = NULL; 

     if(isset($options['button_color'])) 
      $view->vars['button_color'] = $options['button_color']; 
     else 
      $view->vars['button_color'] = NULL; 
    } 

    /** 
    * @param OptionsResolverInterface $resolver 
    */ 
    public function setDefaultOptions(OptionsResolverInterface $resolver) 
    { 
     $resolver->setDefaults(array(
      'button_image' => null, 
      'button_color' => null, 
     )); 
    } 
}

现在一切工作正常:)
