Question

我下面有以下功能，可以正常登录和重定向两个选项，但是我没有收到任何错误！ -如何也可以覆盖错误消息？

刀片：

   <div>
      {{ Form::label('username', 'Username') }}
      {{ Form::text('username', Input::old('username'), array('class' => 'form-control', 'required' => 'required')) }}

       <div class="invalid-feedback">{{ $errors->first('username') }}</div>

功能

：

public function processLogin() {

    // Lets create some simple validation rules for login

    $rules = array(

        'username' => 'required',
        'password' => 'required',
    );

    // Lets check the guest filled in all the correct details :)

    $validator = Validator::make(Input::all(), $rules);

    // Lets redirect back to login page if they have not

    if ($validator->fails()) {
        return Redirect::to('/')
            ->withErrors($validator)
            ->withInput(Input::except('password')); //Sends back only room name
    } else {
        // We will create an array of login information :)

        $loginData = array(
            'username' => Input::get('username'),
            'password' => Input::get('password'),
        );

        // Lets Login

        if (Auth::attempt($loginData)) {
            // If they logged in correct lets give them this :)

            return Redirect::away('https://google.co.nz/');
        } else {
            // If not they can have this

            return Redirect::to('/');
        }
    }

Answer 1

为了替换错误消息，请为自定义消息创建一个数组：

    $customMessages = [
        'username.required' => 'Username cannot be empty.',
        'password.required' => 'Password cannot be empty.',
    ];
    $validator = Validator::make($request->all(),$rules,$customMessages);

您可以查看文档here。

验证规则：

$rules = [
                'username' => 'required',
                'password' => 'required',
            ];

如果验证失败，则自定义消息

 $messages = ['username' => 'error with username.',
'password'=>'error with password.'];

使用规则验证输入，添加自定义消息

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

嘿哥们，您没有传递任何请求参数，因为它不起作用

public function processLogin(Request $request) {

// Lets create some simple validation rules for login

$rules = array(

    'username' => 'required',
    'password' => 'required',
);

// Lets check the guest filled in all the correct details :)

$validator = Validator::make(Input::all(), $rules);

// Lets redirect back to login page if they have not

if ($validator->fails()) {
    return Redirect::to('/')
        ->withErrors($validator)
        ->withInput(Input::except('password')); //Sends back only room name
} else {
    // We will create an array of login information :)

    $loginData = array(
        'username' => Input::get('username'),
        'password' => Input::get('password'),
    );

    // Lets Login

    if (Auth::attempt($loginData)) {
        // If they logged in correct lets give them this :)

        return Redirect::away('https://google.co.nz/');
    } else {
        // If not they can have this

        return Redirect::to('/');
    }
}

别忘了导入请求类

use Illuminate\Http\Request;

删除缓存以在终端上提供以下命令

php artisan config:cahce 
php artisan view:clear 
php artisan route:clear

Okey，因此您尝试更改“默认”错误消息，而不创建新规则。我看到上面有一些答案，但这是我的2美分，非常干净和简单。

public function store(Request $request)
{
    $messages = [
        'username.required' => 'You must have a username!',
        'password.required' => 'Please add a password...'
    ];

    $request->validate([
        'username' => 'required',
        'password' => 'required'
    ], $messages);

   // And here is the code that should be executed if the validation is valid

   return 'Everything seems to work!';
}
