Laravel 5.7验证错误未显示

Question

I have the following function below that is logging in fine and redirecting fine in both options however I am not getting any errors!! - How can I also override the error messages?

Blade:

   <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>

Function:

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

in order to replace the error message, create an array for the custom messages:

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

You can look at the docs here .

Answer 2

Validation rules:

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

Custom messages if validation fails

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

Validate input with rules, adding in custom messages

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

Answer 3

buddy, you don't pass any request parameter for that it's not working

public function processLogin(Request $request) {

// Let's create some simple validation rules for login

$rules = array(

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

// let's check the guest filled in all the correct details :)

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

// Let's 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 incorrect let's give them this :)

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

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

don't forget to import request class

use Illuminate\Http\Request;

remove cache to give the following command on your terminal

php artisan config:cache 
php artisan view:clear 
php artisan route:clear

Okey, so you are trying to change the "default" errors messages, and not create a new rule. I see some above have been answering but this is my 2 cents, very clean and simple.

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!';
}
