Symfony2表单小部件容器属性

Question

我需要为widget容器设置一个类，但不知道Symfony如何将属性传递给“widget_container_attributes”块

小部件容器模板：

{% block form_widget %}
{% spaceless %}
    <div {{ block('widget_container_attributes') }}>
        {{ block('field_rows') }}
        {{ form_rest(form) }}
    </div>
{% endspaceless %}
{% endblock form_widget %}

示例结果：

<div class="MY-CLASS">
    <label class="required" for="page_title">Title</label>
    <input type="text" value="Next subpage" maxlength="500" required="required" name="page[title]" id="page_title">
</div>

我该怎么做？

Answer 1

试

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

    {% block field_rows %}
    {% spaceless %}
        {% for child in form %}
        {{ form_row(child) }}
    {% endfor %}
    {% endspaceless %}
    {% endblock field_rows %}

    {% block field_row %}
    {% spaceless %}
        <div class="myclass">
          {{ form_label(form, label|trans) }}
          {{ form_widget(form) }}
          {{ form_errors(form) }}                            
       </div>
    {% endspaceless %}
    {% endblock field_row %}
