Question

我正在使用我的laravel应用程序中的pw更改表单。我想将验证器与自定义错误消息一起使用。

我的代码如下所示：

  $rules = [
    'username' => 'required|max:255',
    'oldpassword' => 'required|max:255',
    'newpassword' => 'required|min:6|max:255|alpha_num',
    'newpasswordagain' => 'required|same:newpassword',
  ];
  $messages = [
     'username.required' => Lang::get('userpasschange.usernamerequired'),
     'username.max:255' => Lang::get('userpasschange.usernamemax255'),
     'oldpassword.required' => Lang::get('userpasschange.oldpasswordrequired'),
     'oldpassword.max:255' => Lang::get('userpasschange.oldpasswordmax255'),
     'newpassword.required' => Lang::get('userpasschange.newpasswordrequired'),
     'newpassword.min:6' => Lang::get('userpasschange.newpasswordmin6'),
     'newpassword.max:255' => Lang::get('userpasschange.newpasswordmax255'),
     'newpassword.alpha_num' => Lang::get('userpasschange.newpasswordalpha_num'),
     'newpasswordagain.required' => Lang::get('userpasschange.newpasswordagainrequired'),
     'newpasswordagain.same:newpassword' => Lang::get('userpasschange.newpasswordagainsamenewpassword'),
 ];

  $validator = Validator::make($request->all(), $rules, $messages);
  $validator->setCustomMessages($messages);

  Log::debug("custommessages: " . json_encode($messages));
  Log::debug("messages: " . json_encode($validator->messages()));

在日志中 custommessages 会显示我的自定义信息，但在下一行中会显示原始的消息。

我正在使用official doc。

有人遇到这个问题吗？

Answer 1

重写和推荐的方法。参考手册https://laravel.com/docs/5.5/validation#creating-form-requests

使用请求文件。

运行php artisan make:request UpdateUserPasswordRequest
写入请求文件

namespace App\Http\Requests;

class UpdateUserPasswordRequest extends FormRequest
{
    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        // only allow updates if the user is logged in
        return \Auth::check();
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        return [
            'username' => 'required|max:255',
            'oldpassword' => 'required|max:255',
            'newpassword' => 'required|min:6|max:255|alpha_num',
            'newpasswordagain' => 'required|same:newpassword',
        ];
    }

    /**
     * Get the validation attributes that apply to the request.
     *
     * @return array
     */
    public function attributes()
    {
        return [
            'username'            => trans('userpasschange.username'),
            'oldpassword'             => trans('userpasschange.oldpassword'),
            'newpassword'             => trans('userpasschange.newpassword'),
            'newpasswordagain'       => trans('userpasschange.newpasswordagain'),
        ];
    }

    /**
     * Get the validation messages that apply to the request.
     *
     * @return array
     */
    public function messages()
    {
// use trans instead on Lang 
        return [
     'username.required' => Lang::get('userpasschange.usernamerequired'),
     'oldpassword.required' => Lang::get('userpasschange.oldpasswordrequired'),
     'oldpassword.max:255' => Lang::get('userpasschange.oldpasswordmax255'),
     'newpassword.required' => Lang::get('userpasschange.newpasswordrequired'),
     'newpassword.min:6' => Lang::get('userpasschange.newpasswordmin6'),
     'newpassword.max:255' => Lang::get('userpasschange.newpasswordmax255'),
     'newpassword.alpha_num' =>Lang::get('userpasschange.newpasswordalpha_num'),
     'newpasswordagain.required' => Lang::get('userpasschange.newpasswordagainrequired'),
     'newpasswordagain.same:newpassword' => Lang::get('userpasschange.newpasswordagainsamenewpassword'),
      'username.max:255' => 'The :attribute field must  have under 255 chars',
        ];
    }

在UserController中

<?php namespace App\Http\Controllers;


// VALIDATION: change the requests to match your own file names if you need form validation
use App\Http\Requests\UpdateUserPasswordRequest as ChangePassRequest;
//etc

class UserCrudController extends Controller
{
public function chnagePassword(ChangePassRequest $request)
{
 // save new pass since it passed validation if we got here
}
}

Answer 2

对于Laravel 7.x ， 6.x ， 5.x
定义了自定义规则后，您可以在控制器验证中使用它，例如：

$validatedData = $request->validate([
       'f_name' => 'required|min:8',
       'l_name' => 'required',
   ],
   [
      'f_name.required'=> 'Your First Name is Required', // custom message
      'f_name.min'=> 'First Name Should be Minimum of 8 Character', // custom message
      'l_name.required'=> 'Your Last Name is Required' // custom message
   ]
);

对于本地化，您可以使用：

['f_name.required'=> trans('user.your first name is required'],

希望这对您有帮助...

Answer 3

在Validator::make

中指出消息后

$validator = Validator::make($request->all(), $rules, $messages);

你不应该再说一遍

$validator->setCustomMessages($messages); // don't do that

注意

更好使用请求验证的方法是移动them to another file

Answer 4

$messages = [
     'username.required' => Lang::get('userpasschange.usernamerequired'),
     'username.max' => Lang::get('userpasschange.usernamemax255'),
     'oldpassword.required' => Lang::get('userpasschange.oldpasswordrequired'),
     'oldpassword.max' => Lang::get('userpasschange.oldpasswordmax255'),
     'newpassword.required' => Lang::get('userpasschange.newpasswordrequired'),
     'newpassword.min' => Lang::get('userpasschange.newpasswordmin6'),
     'newpassword.max' => Lang::get('userpasschange.newpasswordmax255'),
     'newpassword.alpha_num' => Lang::get('userpasschange.newpasswordalpha_num'),
     'newpasswordagain.required' => Lang::get('userpasschange.newpasswordagainrequired'),
     'newpasswordagain.same:newpassword' => Lang::get('userpasschange.newpasswordagainsamenewpassword'),
 ];

尝试不要使用：255和：6结尾。

错误：

'username.max:255' => Lang::get('userpasschange.usernamemax255'),

正确：

'username.max' => Lang::get('userpasschange.usernamemax255'),

Laravel 5.5使用自定义消息进行验证
