问题描述

Symfony2 Form 组件似乎无法处理这种常见情况.下面是我想要的在我的 html

代码如下:

 ->add('code', 'choice', array('选择' =>大批('食物' =>数组('披萨','汉堡','冰淇淋'),'音乐' =>数组('小马','小','口袋'),),'多个' =>真的,'扩展' =>真的,'必需' =>真的));

实际上给出了错误的输出:

这很奇怪,因为 expanded =>false 正确处理

请问这种情况如何处理?

解决方案

好的,这里是 form_theme 解决方案

{% block _user_code_widget %}<div {{ block('widget_container_attributes') }}>{% 用于名称,form.vars.choices 中的选项 %}<ul><li class="checkbox_category"><input type="checkbox" class="checkallsub"/>{{ 姓名 }}{% for key,choice in choice %}
  • {{ form_widget(form[key]) }}{{ form_label(form[key]) }}
  • {% 结束为 %}{% 结束为 %}

    {% 结束块 %}

    当然缺少额外的 js 层,但您明白了.

    It seems that Symfony2 Form component does not handle this common case. Below is what I want in my html

    The code looks like :

            ->add('code', 'choice', array(
                'choices' => array(
                    'Food'  => array('pizza', 'burger', 'icecream'),
                    'Music' => array('poney', 'little', 'pocket'),
                ),
                'multiple' => true,
                'expanded' => true,
                'required' => true
            ));
    

    Which gives in reality the wrong output :

    It's wierd because the case with expanded => false is correctly handled

    How to handle that case please ?

    解决方案

    Ok so here's the form_theme solution for this

    {% block _user_code_widget %}
        <div {{ block('widget_container_attributes') }}>
            {% for name, choices in form.vars.choices %}
                <ul>
                    <li class="checkbox_category">
                        <input type="checkbox" class="checkallsub" /> {{ name }}
                    </li>
    
                    {% for key,choice in choices %}
                        <li class="indent">
                            {{ form_widget(form[key]) }}
                            {{ form_label(form[key]) }}
                        </li>
                    {% endfor %}
                </ul>
            {% endfor %}
        </div>
    {% endblock %}
    

    Of course the extra js layer is missing, but you get the idea.
