我的编辑表单上的表单集合的 Twig 渲染有问题。 表单加载没有问题，但集合字段的标签加倍并从选项修改为数字，jsfiddle 将显示我的意思。

Twig 模板:

田间 Twig :

{% block _survey_question_answerId_entry_widget %}
    <div class="row multiple-choice-container">
        <div class="form-group">
            {{ form_label(form.value, null, {'label_attr': {'class': 'col-sm-2 control-label'} } ) }}
            <div class="col-md-8">
                <div class="input-group">
                    <div class="input-group-addon">
                        <span class="glyphicon glyphicon-record" aria-hidden="true"></span>
                    </div>
                    {{ form_widget(form.value, {'attr': {'class': 'form-control'} } ) }}
                    {{ form_errors(form.value) }}
                </div>
            </div>
            <div class="col-md-2">
                <div class="btn-group">
                    <a href="#" class="add-choice btn btn-default" aria-label="Add Choice">
                        <span class="glyphicon glyphicon glyphicon-plus" aria-hidden="true"></span>
                    </a>
                    <a href="#" class="remove-choice btn btn-default" aria-label="Remove Choice">
                        <span class="glyphicon glyphicon glyphicon-minus" aria-hidden="true"></span>
                    </a>
                </div>

最佳答案

    ->add('answerId', CollectionType::class, [
        'entry_options' => [
          'label' => false,
        ],
        'entry_type' => AnswerType::class,
        'allow_add' => true,
        'allow_delete' => true,
        'label' => false,
        'by_reference' => false,
    ])

这应该可以完成工作
