如何使用 Laravel 验证复选框？

Question

我正在尝试验证 Laravel 5.3 中的表单。表单有复选框。我至少需要一个复选框 selected 才能使表单有效。这是我的表格

这是我的表格

<div class="form-group {{ $errors->has('gender') ? 'has-error' : ''}}">
    <div class="col-md-2"></div>
    <div class="col-md-10">
        <label for="gender_" class="checkbox-inline">
            {!! Form::checkbox('gender', '', null, ['id' => 'gender_']) !!}
            {{ trans('blogs.gender_') }}
        </label>

        <label for="gender_1" class="checkbox-inline">
            {!! Form::checkbox('gender', '1', null, ['id' => 'gender_1']) !!}
            {{ trans('blogs.gender_1') }}
        </label>

        <label for="gender_2" class="checkbox-inline">
            {!! Form::checkbox('gender', '2', null, ['id' => 'gender_2']) !!}
            Female
        </label>

        {!! $errors->first('gender', '<p class="help-block">:message</p>') !!}
    </div>
</div>

<div class="form-group {{ $errors->has('name') ? 'has-error' : ''}}">
    {!! Form::label('name',trans('blogs.name'),['class' => 'col-md-2 control-label']) !!}
    <div class="col-md-10">
        {!! Form::text('name',null, ['class' => 'form-control']) !!}
        {!! $errors->first('name', '<p class="help-block">:message</p>') !!}
    </div>
</div>

我正在使用 FormRequest 对象。这是我的rules()方法

/**
 * Get the validation rules that apply to the request.
 *
 * @return array
 */
public function rules()
{
    return [
        'gender' => 'required'
    ];
}

但是，验证失败，除非我 select 每个复选框！

如何才能正确确保验证仅在未 select 复选框时才会失败？

您的 rules() 看起来是正确的，因此无需更改。尝试以下：

<div class="form-group {{ $errors->has('gender') ? 'has-error' : ''}}">
  <div class="col-md-2"></div>
  <div class="col-md-10">
    <label for="gender_0" class="checkbox-inline">
      {!! Form::checkbox('gender[]', 0, null, ['id' => 'gender_0']) !!}
      {{ trans('blogs.gender_') }}
    </label>

    <label for="gender_1" class="checkbox-inline">
      {!! Form::checkbox('gender[]', 1, null, ['id' => 'gender_1']) !!}
      {{ trans('blogs.gender_1') }}
    </label>

    <label for="gender_2" class="checkbox-inline">
      {!! Form::checkbox('gender[]', 2, null, ['id' => 'gender_2']) !!}
      Female
    </label>

    {!! $errors->first('gender', '<p class="help-block">:message</p>') !!}
  </div>
</div>

<div class="form-group {{ $errors->has('name') ? 'has-error' : ''}}">
  {!! Form::label('name',trans('blogs.name'),['class' => 'col-md-2 control-label']) !!}
  <div class="col-md-10">
    {!! Form::text('name',null, ['class' => 'form-control']) !!}
    {!! $errors->first('name', '<p class="help-block">:message</p>') !!}
  </div>
</div>

希望对您有所帮助！
