如何在Laravel中自定义错误消息？

Question

这是我的代码：

public function store(Request $request){

    $this->validate($request, [
        'name' => 'required',
        'email' => 'required|email',
        'content' => 'required|min:10',
    ]);

    $new_array = array();
    $new_array['name'] = $request->name;
    $new_array['email'] = $request->email;
    $new_array['content'] = $request->content;
    contact::create($new_array);

    return back();
}

现在我需要为这些过滤器设置一些新的错误信息（例如：required，email，..） 。

当前，这是默认的错误消息required：

名称字段是必需的。

我该如何更改？

Answer 1

您可以使用以下命令创建 Laravel 请求来处理验证

php artisan make:request RequestName

您将在 app\Http\Request 中找到该文件

在文件中，您将找到 rules() 函数，您可以在其中提及所有规则

 public function rules()
    {
        return [
            'name' => 'required',
        ];
    }

您可以为自定义消息创建 message() 函数，例如

 public function messages()
    {
        return[
            'name.required' => 'The name field is required.'
        ];
    }

在控制器方法中添加此请求

public function methodName(RequestName $request)
    {
       //Your code
    }

Crate rules

public function user_registration_rules(array $data)
{
  $messages = [
    'full-name.required' => 'Please enter full name',     
    'address.required' => 'Please enter address'
  ];

  $validator = Validator::make($data, [
    'full-name' => 'required|min:5|max:70', 
    'address' => 'required'     
  ], $messages);

  return $validator;
}

Use in controller like this

$validator = $this->user_registration_rules($request_data);   
if($validator->fails())
{
  return redirect()->back()->withErrors($validator)->withInput();
}

按照此操作：查看：

<div class="col-md-3">
    {{Form::label('Deposit Amount')}}
    {{Form::text('deposit_amount',Input::old('deposit_amount'),array('class'=>"form-control"))}}
    <span class="error">{!!$errors->first('deposit_amount')!!}</span>
    </div>

控制器

 use App\Http\Requests;
    use Illuminate\Http\Request;
    use Illuminate\Support\Facades\Input;
    use DB;
    use Hash;
    use Auth;
    use App\PaymentModel;
    use Redirect;
    use Response;

class TransactionController extends Controller
{
  public function payment(Request $request){

   $validator = Validator::make(Input::all(),  PaymentModel::Rules(), PaymentModel::$message);
   if ($validator->fails())
   {
      return \Redirect::back()->withErrors($validator)->withInput();
  }
  else
  {

    $deposit_amount=Input::get("deposit_amount");

    $obj = new PaymentModel();

    $obj->deposit_amount=$deposit_amount;

    if ($obj->save()) {

        Session::flash('success', 'Saved Successfully !!');

    } else {
      Session::flash('error', 'Some thing went wrong!!');
    }

    }

    return Redirect::action('TransactionController@payment');
  }
  }

模型

   public static function Rules(){
         $rules= array(
        'deposit_amount'=>'required|numeric',       
        ); 
       return $rules;
    }

     public static  $messages=array(
         'deposit_amount.required'=>'Please Enter Amount ',
        'deposit_amount.numeric'=>'Deposit Amount Must be a number ', 
        );
