php - 如何在 Laravel 中合并两个请求

Question

在我的 Laravel (5.1) 项目中，我需要创建一个验证表单的请求。

但是对于这个请求，我想合并两个不同的请求:

第一个请求:

class AdvertisementRequest extends Request {

    public function authorize()
    {

        return true;
    }

    public function rules()
    {
        return [
            'ads_type' => 'required|numeric|in:0,1',
            'category' => 'required|numeric|exists:categories,id',
            'title' => 'required|alpha_num|max:45',
            'description' => 'required|alpha_num|max:2000',
            'price' => 'required|numeric',
        ];
    }

}

第二个请求:

class UserRegisterRequest extends Request {

    public function authorize()
    {

        return true;
    }

    public function rules()
    {
        $rules = [
            'form_type' => 'required|numeric|in:0,1',
            'user_type' => 'required|numeric|in:0,1',
            'phone' => 'required|phone_number',
            'region' => 'required|numeric|exists:regions,id',
            'department' => 'required|numeric|exists:departments,code',
            'postal_code' => 'required|postal_code',
            'city' => 'alpha|max:45',
            'id_city' => 'required|numeric|exists:cities,id',
            'last_name' => 'required|alpha_sp|max:45',
            'first_name' => 'required|alpha_sp|max:45',
            'pseudo' => 'required|alpha|max:45|unique:users',
            'email' => 'required|email|max:255|unique:users',
            'password' => 'required|alpha_num|min:6|max:45',
        ];

        return $rules;
    }
}

我想创建第三个请求，将其他两个请求结合起来:

class UserAdvertisementRegisterRequest extends Request {

    public function authorize()
    {

        return true;
    }

    public function rules()
    {
        $rules = [
            'ads_type' => 'required|numeric|in:0,1',
            'category' => 'required|numeric|exists:categories,id',
            'title' => 'required|alpha_num|max:45',
            'description' => 'required|alpha_num|max:2000',
            'price' => 'required|numeric',

            'form_type' => 'required|numeric|in:0,1',
            'user_type' => 'required|numeric|in:0,1',
            'phone' => 'required|phone_number',
            'region' => 'required|numeric|exists:regions,id',
            'department' => 'required|numeric|exists:departments,code',
            'postal_code' => 'required|postal_code',
            'city' => 'alpha|max:45',
            'id_city' => 'required|numeric|exists:cities,id',
            'last_name' => 'required|alpha_sp|max:45',
            'first_name' => 'required|alpha_sp|max:45',
            'pseudo' => 'required|alpha|max:45|unique:users',
            'email' => 'required|email|max:255|unique:users',
            'password' => 'required|alpha_num|min:6|max:45',
        ];

        return $rules;
    }
}

是否有任何解决方案可以在不重复我的代码的情况下做到这一点？

抱歉我的英语不好:/.

先谢谢您的回复!

最简单的方法是通过以下方式在 UserAdvertisementRegisterRequest::rules 方法中生成验证规则的合并列表:

class UserAdvertisementRegisterRequest extends Request { 
  public function rules()
  {
    return array_merge(
      with(new AdvertisementRequest)->rules(), 
      with(new UserRegisterRequest)->rules()
    );
  }
}
