使用Laravel 5.1,是否只有在满足两个条件时才需要字段?

在下面的代码示例中,在规则中,我有field2_en和field2_de。我为每个字段设置了2个required_if规则,如果满足2 OR或者required_if规则中的1个,则该字段变为必需字段。这不是我想要的。这就是我想要的:

  • 我希望只有在language = en AND时才需要field2_en radiobutton = 2
  • 我希望仅当language = de AND时才需要field2_de radiobutton = 2

AddRequest.php

namespace App\Http\Requests\Post;

use App\Http\Requests\Request;

class AddRequest extends Request
{

    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return auth();
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        return [
            'language'              => ['required', 'in:en,de'],
            'field1_en'             => ['required_if:language,en'],
            'field1_de'             => ['required_if:language,de'],
            'radiobutton'           => ['required', 'in:1,2'],
            'field2_en'             => ['required_if:language,en', 'required_if:radio,2'],
            'field2_de'             => ['required_if:language,de', 'required_if:radio,2']
        ];
    }
}

我已经能够有时候()像下面这样或者使用扩展,但我想知道是否有其他方法可以做到这一点,因为我使用的是laravel-jsvalidation插件而且它没有使用这种有时有条件的验证。

protected function getValidatorInstance()
{
    $validator = parent::getValidatorInstance();

    $validator->sometimes('field2_en', 'required|min:2', function($input)
    {
        return ($input->language == 'en' && $input->radiobutton == '2');
    });

    ...

    return $validator;
}
