Question

如何使用此格式返回自定义错误消息？

$this->validate($request, [
  'thing' => 'required'
]);

Answer 1

要获取自定义错误消息，您需要在第三个参数上传递自定义错误消息，例如

$this->validate(
    $request, 
    ['thing' => 'required'],
    ['thing.required' => 'this is my custom error message for required']
);

Answer 2

对于多字段，角色和字段角色特定消息

$this->validate(
        $request, 
        [   
            'uEmail'             => 'required|unique:members',
            'uPassword'          => 'required|min:8'
        ],
        [   
            'uEmail.required'    => 'Please Provide Your Email Address For Better Communication, Thank You.',
            'uEmail.unique'      => 'Sorry, This Email Address Is Already Used By Another User. Please Try With Different One, Thank You.',
            'uPassword.required' => 'Password Is Required For Your Information Safety, Thank You.',
            'uPassword.min'      => 'Password Length Should Be More Than 8 Character Or Digit Or Mix, Thank You.',
        ]
    );

Answer 3

您需要先在视图页面中添加以下行，以显示错误消息：

<div class="row">
        <div class="col-md-4 col-md-offset-4 error">
            <ul>
                @foreach($errors->all() as $error)
                    <li>{{$error}}</li>
                @endforeach
            </ul>
        </div>
    </div>

这是一个演示控制器，错误消息将显示在该页面上：

public function saveUser(Request $request)

 {
     $this->validate($request,[
        'name' => 'required',          
        'email' => 'required|unique:users',          
        ]);
  $user=new User();
  $user->name= $request->Input(['name']);
  $user->email=$request->Input(['email']);
  $user->save();
  return redirect('getUser');
 }

Answer 4

https://laravel.com/docs/5.3/validation#working-with-error-messages

$messages = [
    'required' => 'The :attribute field is required.',
];

$validator = Validator::make($input, $rules, $messages);

＆＃34;在大多数情况下，您可能会在语言文件中指定自定义消息，而不是直接将它们传递给Validator。为此，请在resources / lang / xx / validation.php语言文件中将消息添加到自定义数组。＆＃34;

Laravel 5.3使用$ this-＆gt; validate（）返回自定义错误消息
