是否可以做我想要的东西?为表单构建器创建自定义选项添加方法

我知道如何创建一个表单字段:

public function buildForm(FormBuilderInterface $builder, array $options) 
{ 
    $builder 
     ->add('field', null, array_of_options) 
    ; 
} 

add method第三个参数是像predifined选项数组:labelattr,等等...如果你做这样的事情:

$builder 
    ->add('field', null, array('my_option' => 'my value')); 

你会得到这样的错误:

The option "my_option" 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", "data", "data_class", "disabled", "empty_data", "error_bubbling", "error_mapping", "extra_fields_message", "grouping", "inherit_data", "intention", "invalid_message", "invalid_message_parameters", "label", "label_attr", "mapped", "max_length", "method", "pattern", "post_max_size_message", "precision", "property_path", "read_only", "required", "rounding_mode", "translation_domain", "trim", "validation_groups", "virtual" 

我已阅读并理解this但它不是我在找的东西。我不想通过控制器的createForm方法传递选项。

我想要的是为add method中的第三个参数的数组创建自定义option

对不起,如果我不清楚!

我已经解决了这个问题。

首先,回答@ hcoat的评论,我想有3 custom optionsopen_colclose_colcol_dims)为form theming。我通过他们在attr选项:

public function buildForm(FormBuilderInterface $builder, array $options) 
{ 
    $builder 
     ->add('field1', null, array('attr' => array('open_col' => true, 'col_dims' => '2-8'))) 
     ->add('field2', null, array('attr' => array('close_col' => true, 'col_dims' => '6-8'))) 
    ; 
} 

和检索的那些选项值如下:

{% block form_row %} 
{% spaceless %} 



{% set open_col, close_col = 'open_col', 'close_col' %} 
    {% if open_col in attr|keys %} 
    <div class="mws-form-row"> 
     <div class="mws-form-cols"> 
      <div class="mws-form-col-{{ (open_col in attr|keys) ? attr['col_dims']:'4-8' }}"> 
    {% elseif close_col in attr|keys %} 
      <div class="mws-form-col-{{ (open_col in attr|keys) ? attr['col_dims']:'4-8' }}"> 
    {% else %} 
    <div class="mws-form-row"> 
    {% endif %} 

     {{ form_label(form) }} 
     <div class="mws-form-item"> 
      {{ form_widget(form) }} 
     </div> 
    {% if close_col in attr|keys %} 
      </div> 
     </div> 
    </div> 
    {% elseif open_col in attr|keys %} 
    </div> 
    {% else %} 
    </div> 
    {% endif %} 
{% endspaceless %} 
{% endblock form_row %} 

它工作正常!

我认为你的解决方案并不完美。当然,它的工作,但你应该考虑另一种解决方案。

您应该使用允许您添加自己的属性的选项解析器。 http://symfony.com/doc/current/components/options_resolver.html

因此,在您formType类,你应该添加以下方法:

public function setDefaultOptions(OptionsResolverInterface $resolver) 
{ 
    $resolver->setDefaults(
     array(
      'my_option' => 'my_default_value', 
     ) 
    ); 
} 

然后你就可以在树枝模板得到这个属性为:

{{ my_option }} //it return"my_defaul_value" 
    {{ form.your_field_name.my_option }} //it retun your field value
