为表单构建器添加方法创建自定义选项

有可能做我想做的事吗?

我知道如何创建表单字段:

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

add method的第三个参数是一系列预定义的选项,例如:labelattr等......如果您执行以下操作:

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

你会收到这个错误:

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" 

我已经阅读并了解this,但这不是我想要的。我不想从控制器传递createForm方法中的选项。

我想要的是为option中第三个参数的数组创建自定义add method

对不起,如果我不清楚的话!

我已经解决了这个问题。

首先,要回答@ hcoat的评论,我想为custom options提供3 open_colclose_colcol_dimsform theming)。我在attr选项中传递了它们:

 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')))
    ;
}

并检索这些选项值:

{% 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 %}

一切正常!

我认为你的解决方案并不完美。当然它可以工作,但你应该考虑另一个解决方案。

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

因此,在formType类中,您应该添加以下方法:

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

然后你可以在twig模板中获得这个属性:

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