Displaying the Error Messages in Laravel after being Redirected from controller

Question

How can I display the validation message in the view that is being redirected in Laravel ?

Here is my function in a Controller

public function registeruser()
{
    $firstname = Input::get('firstname');
    $lastname = Input::get('lastname');
    $data  =  Input::except(array('_token')) ;
    $rule  =  array(
                'firstname'       => 'required',
                'lastname'         => 'required',
                   ) ;
    $validator = Validator::make($data,$rule);
    if ($validator->fails())
    {
    $messages = $validator->messages();
    return Redirect::to('/')->with('message', 'Register Failed');
    }
    else
    {
    DB::insert('insert into user (firstname, lastname) values (?, ?)',
                                array($firstname, $lastname));
    return Redirect::to('/')->with('message', 'Register Success');
    }
    }

I know the below given code is a bad try, But how can I fix it and what am I missing

@if($errors->has())
    @foreach ($errors->all() as $error)
        <div>{{ $error }}</div>
    @endforeach
@endif

Update : And how do I display the error messages near to the particular fields

Answer 1

Laravel 4

When the validation fails return back with the validation errors.

if($validator->fails()) {
    return Redirect::back()->withErrors($validator);
}

You can catch the error on your view using

@if($errors->any())
    {{ implode('', $errors->all('<div>:message</div>')) }}
@endif

UPDATE

To display error under each field you can do like this.

<input type="text" name="firstname">
@if($errors->has('firstname'))
    <div class="error">{{ $errors->first('firstname') }}</div>
@endif

For better display style with css.

You can refer to the docs here.

UPDATE 2

To display all errors at once

@if($errors->any())
    {!! implode('', $errors->all('<div>:message</div>')) !!}
@endif

To display error under each field.

@error('firstname')
    <div class="error">{{ $message }}</div>
@enderror

Answer 2

If you want to load the view from the same controller you are on:

if ($validator->fails()) {
    return self::index($request)->withErrors($validator->errors());
}

And if you want to quickly display all errors but have a bit more control:

 @if ($errors->any())
     @foreach ($errors->all() as $error)
         <div>{{$error}}</div>
     @endforeach
 @endif

Answer 3

@if ($errors->has('category'))
    <span class="error">{{ $errors->first('category') }}</span>
@endif

Answer 4

A New Laravel Blade Error Directive comes to Laravel 5.8.13

// Before
@if ($errors->has('email'))
    <span>{{ $errors->first('email') }}</span>
@endif

// After:
@error('email')
    <span>{{ $message }}</span>
@enderror

Answer 5

to Make it look nice you can use little bootstrap help

@if(count($errors) > 0 )
<div class="alert alert-danger alert-dismissible fade show" role="alert">
    <button type="button" class="close" data-dismiss="alert" aria-label="Close">
        <span aria-hidden="true">&times;</span>
    </button>
    <ul class="p-0 m-0" style="list-style: none;">
        @foreach($errors->all() as $error)
        <li>{{$error}}</li>
        @endforeach
    </ul>
</div>
@endif

Answer 6

$validator = Validator::make($request->all(), [ 'email' => 'required|email', 'password' => 'required', ]);

if ($validator->fails()) { return $validator->errors(); }

Answer 7

{!! Form::text('firstname', null !!}

@if($errors->has('firstname')) 
    {{ $errors->first('firstname') }} 
@endif

Answer 8

This is also good way to accomplish task.

@if($errors->any())
  {!! implode('', $errors->all('<div class="alert alert-danger">:message</div>')) !!}
@endif

We can format tag as per requirements.

Answer 9

Below input field I include additional view:

@include('input-errors', ['inputName' => 'inputName']) #For your case it would be 'email'

input-errors.blade.php

@foreach ($errors->get($inputName) as $message)
    <span class="input-error">{{ $message }}</span>
@endforeach

CSS - adds red color to the message.

.input-error {
    color: #ff5555;
}

In case of using toastr use the following to show the error with floating message

@if($errors->any()) 
     <script type="text/javascript">
         toastr.error({{ implode(' ', $errors->all()) }});
    </script> 
@endif

Move all that in kernel.php if just the above method didn't work for you remember you have to move all those lines in kernel.php in addition to the above solution

let me first display the way it is there in the file already..

protected $middleware = [

    \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
];

/**
 * The application's route middleware groups.
 *
 * @var array
 */
protected $middlewareGroups = [
    'web' => [
        \App\Http\Middleware\EncryptCookies::class,
        \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
        \Illuminate\Session\Middleware\StartSession::class,
        \Illuminate\View\Middleware\ShareErrorsFromSession::class,
        \App\Http\Middleware\VerifyCsrfToken::class,
    ],

    'api' => [
        'throttle:60,1',
    ],
];

now what you have to do is

protected $middleware = [
    \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
     \App\Http\Middleware\EncryptCookies::class,
        \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
        \Illuminate\Session\Middleware\StartSession::class,
        \Illuminate\View\Middleware\ShareErrorsFromSession::class,
        \App\Http\Middleware\VerifyCsrfToken::class,
];

/**
 * The application's route middleware groups.
 *
 * @var array
 */
protected $middlewareGroups = [
    'web' => [

    ],

    'api' => [
        'throttle:60,1',
    ],
];

i.e.;
