Question

我正在尝试自定义我的symfony2表单choice_widget_expanded部分，并尝试根据此指令引用choice_widget_collapsed的基础（标准）http://symfony.com/doc/current/cookbook/form/form_customization.html

但我收到错误

Notice: Undefined index: choice_widget_collapsed in /var/www/beta/app/cache/dev/twig/ff/8a/9f46c90c543b16e78e981aeda67b.php line 19

这是我的枝条代码：

{% extends '::base.html.twig' %}

{% use 'form_div_layout.html.twig' with choice_widget_collapsed as base_choice_widget_collapsed %}

{% form_theme form _self %}

{% block choice_widget %}
{% spaceless %}
    {% if expanded %}
        {{ block('choice_widget_expanded') }}
    {% else %}
        {{ block('base_choice_widget_collapsed') }}
    {% endif %}
{% endspaceless %}
{% endblock choice_widget %}


{% block choice_widget_expanded %}
{% spaceless %}
    <div {{ block('widget_container_attributes') }}>
    {% for child in form %}
        {{ form_widget(child) }}
        {{ form_label(child) }}
        <br />
    {% endfor %}
    </div>
{% endspaceless %}
{% endblock choice_widget_expanded %}


{% block contents %}

这适用于我在sf 2.2.1的新作曲家安装。您不需要清除模板更改的缓存以在dev环境中注册，但它值得一试。如果使用操作码缓存，也可能需要停止并启动（不重启）apache / php5-fpm。

由于您只修改choice_widget_expanded所有您真正需要的是：

test.html.twig

{% extends '::base.html.twig' %}

{% form_theme form _self %}

{% block choice_widget_expanded %}
{% spaceless %}
    <div {{ block('widget_container_attributes') }}>
    {% for child in form %}
        {{ form_widget(child) }}
        {{ form_label(child) }}
        <br />
    {% endfor %}
    </div>
{% endspaceless %}
{% endblock choice_widget_expanded %}

{% block body %}
<form>
{{ form_row(form.choice) }}
</form>
{% endblock %}

testAction

/**
 * @Template()
 */
public function testAction()
{
    $builder = $this->createFormBuilder();
    $builder->add('choice', 'choice', array(
            'choices'=>array('one'=>'one', 'two'=>'two', 'three'=>'three'),
            'expanded'=>true
    ));
    $form = $builder->getForm();
    return array('form'=>$form->createView());
}

Answer 2

啊..我确信Dylans的回答是正确的，但对于我使用的（2.0.16）symfony2版本，该表单的模板看起来有点不同，choice_widget_expanded没有它自己的块，但它全部在此

{% block choice_widget %}
{% spaceless %}
{% if expanded %}
    <div {{ block('widget_container_attributes') }}>
    {% for child in form %}
        {{ form_widget(child) }}
        {{ form_label(child) }}
        <br />          {# <-------- Here's my addition to the template #}
    {% endfor %}
    </div>
{% else %}
<select {{ block('widget_attributes') }}{% if multiple %} multiple="multiple"{% endif %}>
    {% if empty_value is not none %}
        <option value="">{{ empty_value|trans }}</option>
    {% endif %}
    {% if preferred_choices|length > 0 %}
        {% set options = preferred_choices %}
        {{ block('widget_choice_options') }}
        {% if choices|length > 0 and separator is not none %}
            <option disabled="disabled">{{ separator }}</option>
        {% endif %}
    {% endif %}
    {% set options = choices %}
    {{ block('widget_choice_options') }}
</select>
{% endif %}
{% endspaceless %}
{% endblock choice_widget %}

我当然应该从我自己的代码库中取出代码，而不是从github获取最新版本，doh！
