Symfony 形式的电台选项之间的换行符 (<br>)

Newline (lt;brgt;) between radio choices in Symfony form(Symfony 形式的电台选项之间的换行符 (lt;brgt;))

问题描述

我有这个表单生成代码..:

I have this form generation code..:

$form = $this->createFormBuilder($task)
            ->add('mode', 'choice', array(
                'label' => false,
                'choices' => array(
                  'mode1' => '1',
                  'mode2' => '2',
                  'mode3' => '3',
                ),
                'multiple' => false,
                'expanded' => true,
                'required' => true,
            ))
            ->getForm();

问题在于呈现的表单具有内联选项(无线电输入)，它们之间没有 <br/> 标记.

The problem is that rendered form has choices (radio inputs) inline, without <br/> tags between them.

另外，我找不到如何使用 twig 模板呈现表单，所以不要触摸 PHP 代码，例如，我如何在我的单选按钮列表中专门装饰"每个选项.

Also, i cannot find how do i render form with a twig template so do not touch PHP code, for example, how can i specially 'decorate' each choice in my radio buttons list.

 <div style='margin:25px'>
            {{ form_start(form_options) }}
            {{ form_widget(form_options) }}
            {{ form_end(form_options) }}
        </div>

如何扩展它?

推荐答案

你可以随意渲染每个表单域.不要使用 {{ form_widget(form_options) }} 使用 {{ form_row (form.fieldName) }} 然后您可以根据需要添加 html 和样式:这是一个例子:

You can render each form field as you like. Do not use {{ form_widget(form_options) }} use {{ form_row (form.fieldName) }} then you can add html and style as you like : This is an exemple :

<div class="checkbox-list">
<label class="checkbox-inline col-md-6">
    <div class="checker" id="uniform-inlineCheckbox21">
        <span class="">
            {{form_row(form.fieldName)}}
        </span>
    </div> 
    fieldName
</label>

您还可以传递对象列表并手动创建您的输入:

You can also pass a list of object and create manually your input :

{% for language in languages %}
<div class="checkbox-list">
    <label class="checkbox-inline col-md-6">
        <div class="checker" id="uniform-inlineCheckbox21">
            <span class="">
                <input type="checkbox"  name="langues[]" id="course{{loop.index}}" value="{{language.id}}" data-title="{{language.designation}}">
            </span>
        </div> 
        {{language.designation}}
    </label>
</div>
{% endfor %}

最后一个解决方案，您可以使用 form_theme 并通过 symfony 覆盖选择小部件用户:http://symfony.com/fr/doc/current/cookbook/form/form_customization.html

Last solution you can use form_theme and override the choices widget user by symfony : http://symfony.com/fr/doc/current/cookbook/form/form_customization.html
