symfony - 为表单生成器添加方法创建自定义选项

Question

可以做我想做的事吗？

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 方法的第三个参数是一组预定义选项，例如:label、attr 等...如果您这样做像这样的东西:

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

您将收到此错误:

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但这不是我要找的。我不想从 Controller 传递 createForm 方法中的选项。

我想要的是为add方法中第三个参数的数组创建一个自定义选项。

抱歉，如果我不清楚!

我已经解决了这个问题。

首先，为了回答@hcoat的评论，我想要3个自定义选项(open_col，close_col，col_dims )用于表单主题。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，如下所示:

{% 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 %}

效果很好!
