public function store(Request $request)
{
//this method will be called when we signup for members
$this->validate($request, [
'title' => 'required|max:255',
'body' => 'required',
]);
return 'success';
}
this will automatically redirected to homepage of Laravel without any exception
i need a validation message there
eg. title is required
Laravel has performed the redirect and stored the errors in the session. It is up to you to modify your view to display the errors that have been put in the session.
You can read more about displaying validation errors in the documentation here.
Code example from that link: (add this to your view)
#if (count($errors) > 0)
<div class="alert alert-danger">
<ul>
#foreach ($errors->all() as $error)
<li>{{ $error }}</li>
#endforeach
</ul>
</div>
#endif

When I use return view('login')->withErrors($validator->errors());, I get the errors returned if any. Now, if I use the Redirect method/class, it doesn't return the data.
I need to use redirect. I tested it in several ways, going through the different errors, but nothing works. I've read documentation, blogs and everything I do doesn't work.
I already tried return Redirect::back()->withErrors(['msg' => 'The Message']); and in the blade `{{ session()->get('msg') }}, but nothing .
I need some help as I have tried many things and nothing works.
Controller:
public function checkUserExists(Request $request)
{
$email = $request->input('email');
$validator = Validator::make(
$request->all(),
[
'email' => ['required', 'max:255', 'string', 'email'],
'g-recaptcha-response' => ['required', new RecaptchaRule],
],
$this->messages
);
if ($validator->fails()) {
// return view('login')->withErrors($validator->errors());
// return Redirect::back()->withErrors(['msg' => 'The Message']);
return Redirect::route('login')->withErrors($validator->errors());
// return Redirect::route('login')->withErrors($validator);
// return redirect()->back()->withErrors($validator->errors());
// return Redirect::back()->withErrors($validator)->withInput();
}
...
}
At the moment my bucket is just with this:
{{-- Errors --}}
#if ($errors->any())
<div class="alert alert-danger" role="alert">
<ul>
#foreach ($errors->all() as $key => $error)
<li>
{{ $error }}
</li>
#endforeach
</ul>
</div>
#endif
Version of Laravel: "laravel/framework": "^7.29",
try this code to pass the errors back to the view:
public function checkUserExists(Request $request)
{
$email = $request->input('email');
$validator = Validator::make(
$request->all(),
[
'email' => ['required', 'max:255', 'string', 'email'],
'g-recaptcha-response' => ['required', new RecaptchaRule],
],
$this->messages
);
if ($validator->fails()) {
return redirect()->back()->withErrors($validator)->withInput();
}
...
}
& in your view, you can access the errors using with:
{{-- Errors --}}
#if ($errors->any())
<div class="alert alert-danger" role="alert">
<ul>
#foreach ($errors->all() as $error)
<li>{{ $error }}</li>
#endforeach
</ul>
</div>
#endif
this should work if your view is correct
and you are using the correct path to your view
in your redirect()->back() method
I am coding in Laravel 5.6 and i have a layout file called errors.blade with the contents of:
#if(session('status'))
<div class="alert alert-dismissible alert-success">
<button type="button" class="close" data-dismiss="alert">×</button>
{{ session('status') }}
</div>
#endif
#if(count($errors))
<div class="alert alert-dismissible alert-danger">
<button type="button" class="close" data-dismiss="alert">×</button>
#foreach($errors as $error)
<ul>
<li>{{ $error }}</li>
</ul>
#endforeach
</div>
#endif
And my controller that insterts data into db and uses the $this->validate is:
public function store()
{
$this->validate(request(), [
'first_name' => 'required',
'last_name' => 'required',
'email' => 'required|email',
'username' => 'required',
'password' => 'required|confirmed',
'discord' => 'required'
]);
Admin::create([
'first_name' => request('first_name'),
'last_name' => request('last_name'),
'email' => request('email'),
'username' => request('username'),
'password' => bcrypt(request('password')),
'discord' => request('discord'),
]);
return redirect('/admin/login')->with('status', 'Install successfully completed. Use the form below to login to your account.');
}
As you can see i am sending back a session with the name of status which i have setup to show in my errors file, which works perfectly. But as soon as i leave a field blank or mismatch the passwords on purpose i get this from the actual $errors:
This is happening on all pages. I don't know what exactly is the problem. The status messages work, but the error message here doesn't work. It happens with any error with validator or even with the:
return redirect()->route('admin-login')->withErrors('Incorrect
Username or Password.');
Just a little more info, i am using a guard for admin and guard for the default laravel web to separate sessions of admin and regular users. I don't know if this could be any of the cause. Any help is greatly appreciated to remove this road block for me and any other users who have ran or may run into this.
Change the #foreach to this:
#foreach($errors->all() as $error)
I use Laravel 5.4 on hosting. My validation method is working, but it doesn't show messages. I do all the needed operations for displaying errors but it doesn't work.
#if($errors->has('recipient'))
<div class="form-group">
<label class="col-lg-2 control-label"></label>
<div class="col-lg-10">
<div class="alert alert-danger">
<ul>
#foreach ($errors->get('recipient') as $error)
<li>{{ $error }}</li>
#endforeach
</ul>
</div>
</div>
</div>
#endif
I use {{ csrf_field() }} tokens. Validation rules work if wrong user types are used, but messages are not displayed.
My send method:
public function send(Request $request)
{
$this->validator($request->all())->validate();
$this->create($request->all());
return redirect($this->redirectToAfterSendMessage);
}
My validator code:
protected function validator(array $data)
{
return Validator::make($data, [
"$this->recipient" => [
'sometimes',
'required',
'email',
'exists:users,email',
Rule::notIn([auth()->user()->email])
],
"$this->subject" => 'sometimes|required|min:10',
"$this->message" => 'sometimes|required|min:50',
], $this->validator_messages());
}
My routes:
Route::get('/compose', 'InboxController#compose') ->name('compose');
Route::post('/compose', 'InboxController#send');
Result of dump($errors):
ViewErrorBag {#244 ▼
#bags: []
}
EDITED
To fix your current problem, change $errors->get('recipient') to $errors->all().
It should look like this:
#foreach ($errors->all() as $error)
<li>{{ $error }}</li>
#endforeach
--
This isn't a direct solution for your question. However an even better approach (imo) than yours are custom requests. You can quickly generate custom requests by using the following command:
php artisan make:request CustomRequest
After that you can change type from Request to CustomRequest
public function send(CustomRequest $request)
{
$this->create($request->all());
return redirect($this->redirectToAfterSendMessage);
}
And in CustomRequest.php your extract your validation logic like so:
<?php
namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;
class CustomRequest extends FormRequest
{
/**
* Determine if the user is authorized to make this request.
*
* #return bool
*/
public function authorize()
{
return true;
}
/**
* Get the validation rules that apply to the request.
*
* #return array
*/
public function rules()
{
return [
'name' => 'required',
'email' => 'required',
'message' => 'required',
];
}
public function messages()
{
return [
'name.required' => 'Name is required.',
'email.required' => 'Email is required.',
'message.required' => 'Message is required.',
];
}
}
Hope this helps.
You need to change:
"$this->recipient"
"$this->subject"
"$this->message"
To:
'recipient'
'subject'
'message'
I have some trouble with validation in Laravel 5.2
When i try validate request in controller like this
$this->validate($request, [
'title' => 'required',
'content.*.rate' => 'required',
]);
Validator catch error, but don't store them to session, so when i'm try to call in template this code
#if (isset($errors) && count($errors) > 0)
<div class="alert alert-danger">
<ul>
#foreach ($errors->all() as $error)
<li>{{ $error }}</li>
#endforeach
</ul>
</div>
#endif
Laravel throw the error
Undefined variable: errors (View: /home/vagrant/Code/os.dev/resources/views/semantic/index.blade.php)
When i'm try validate with this code
$validator = Validator::make($request->all(), [
'title' => 'required',
'content.*.rate' => 'required'
]);
if ($validator->fails()) {
return redirect()
->back()
->withInput($request->all())
->withErrors($validator, 'error');
}
Variable $error also not available in template but if i try to display errors in controller
if ($validator->fails()) {
dd($validator->errors()->all());
}
Errors displays but i can't access to them from template.
What's wrong?
Update as of Laravel 5.2.27
Laravel now supports the web middleware by default as you can see here: source
In other words, you no longer need to wrap your routes around the web middleware group because it does it for you in the RouteServiceProvider file. However, if you are using a version of Laravel between 5.2.0 and 5.2.26, then refer to the method below:
Below only applies to Laravel 5.2.0 to 5.2.26
Without seeing your routes.php or Kernel.php file, here is what I suspect is happening.
The way middlewares work has changed from 5.2 and 5.1. In 5.1, you will see this in your app/Http/Kernel.php file:
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,
];
This array is your application's global HTTP middleware stack. In other words, they run on every request. Take a note at this particular middleware: Illuminate\View\Middleware\ShareErrorsFromSession. This is what adds the $errors variable on every request.
However, in 5.2, things have changed to allow for both a web UI and an API within the same application. Now, you will see this in that same file:
protected $middleware = [
\Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
];
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',
],
];
The global middleware stack now only checks for maintenance. You now have a middleware group called "web" that includes a bulk of the previous global middleware. Remember that it is like this to allow for both a web UI and an API within the same application.
So how do we get that $errors variable back?
In your routes file, you need to add your routes within the "web" middleware group for you to have access to that $errors variable on every request. Like this:
Route::group(['middleware' => ['web']], function () {
// Add your routes here
});
If you aren't going to build an API, another option is to move the "web" middlewares to the global middleware stack like in 5.1.
Try using
return redirect()->back()
->withInput($request->all())
->withErrors($validator->errors()); // will return only the errors
Try to replace:
->withErrors($validator, 'error');
with:
->withErrors($validator);
// Replace
Route::group(['middleware' => ['web']], function () {
// Add your routes here
});
// with
Route::group(['middlewareGroups' => ['web']], function () {
// Add your routes here
});
I have my working validation code in laravel 5.2 like this
first of all create a function in model like this
In model add this line of code at starting
use Illuminate\Support\Facades\Validator;
public static function validate($input) {
$rules = array(
'title' => 'required',
'content.*.rate' => 'required',
);
return Validator::make($input, $rules);
}
and in controller call this function to validate the input
use Illuminate\Support\Facades\Redirect;
$validate = ModelName::validate($inputs);
if ($validate->passes()) {
///some code
}else{
return Redirect::to('Route/URL')
->withErrors($validate)
->withInput();
}
Now here comes the template part
#if (count($errors) > 0)
<div class="alert alert-danger">
<ul>
#foreach ($errors->all() as $error)
<li>{{ $error }}</li>
#endforeach
</ul>
</div>
#endif
and Above all the things you must write your Route like this
Route::group(['middleware' => ['web']], function () {
Route::resource('RouteURL', 'ControllerName');
});
Wrap you Routes in web middleware like below:
Route::group(['middleware' => ['web']], function () {
// Add your routes here
});
and In app\Http\Kernel.php move \Illuminate\Session\Middleware\StartSession::class from the web $middlewareGroups to $middleware
Hope it will solve your problem.
Route
Route::group(['middlewareGroups' => ['web']], function () {
// Add your routes here
Route::resource('/post', 'PostController');
});
Functions
public function store(Request $request){
$this->validate($request, [
//input field names
'title' => 'required|max:20',
'body' => 'required',
]);
}
View
#if (count($errors) > 0)
<div class="alert alert-danger">
<ul>
#foreach ($errors->all() as $error)
<li>{{ $error }}</li>
#endforeach
</ul>
</div>
#endif
This will work
Route::group(['middlewareGroups' => ['web']], function () {
// Add your routes here
});
as well as this also works
Route::post('location',array(
'as'=>'location',
'middlewareGroups'=>'web',
'uses'=>'myController#function'
));
// Controller
$this->validateWith([
'title' => 'required',
'content.*.rate' => 'required',
]);
// Blade Template
#if ($errors->has('title'))
<span class="error">
<strong>{{ $errors->first('title') }}</strong>
</span>
#endif
#if ($errors->has('anotherfied'))
<span class="error">
<strong>{{ $errors->first('anotherfied') }}</strong>
</span>
#endif

I am creating a CRUD of books and what I wanted to do is like the generated auth files that if someone registers and didn't input any in the textbox, a flash message will return. I am doing that now in my crud but I can only make a flash message when a book is successfully created. This is my store function
public function store(Request $request)
{
$this->validate($request, [
'isbn' => 'required|',
'title' => 'required',
'author' => 'required',
'publisher' => 'required'
]);
Session::flash('msg', 'Book added!');
$books = $request->all();
Book::create($books);
return redirect('books');
}
And in my home.blade.php
#if(Session::has('msg'))
<div class="alert alert-success">
{{ Session::get('msg') }}
</div>
#endif
This actually works but I want to show some ready generated error flash when someone didnt complete fields. How can I do that?
It's pretty simple, first there's a sweet nice feature that is the redirect()->with()
So your controller code could be:
public function store(Request $request)
{
$this->validate($request, [
'isbn' => 'required|',
'title' => 'required',
'author' => 'required',
'publisher' => 'required'
]);
if(Book::create($books)){
$message = [
'flashType' => 'success',
'flashMessage' => 'Book added!'
];
}else{
$message = [
'flashType' => 'danger',
'flashMessage' => 'Oh snap! something went wrong'
];
}
return redirect()->action('BooksController#index')->with($message);
}
Then on your view:
#if (Session::has('flashMessage'))
<div class="alert {{ Session::has('flashType') ? 'alert-'.session('flashType') : '' }}">
<button type="button" class="close" data-dismiss="alert" aria-hidden="true">×</button>
{{ session('flashMessage') }}
</div>
#endif
Bonus you can put this on your footer, so the alerts boxes will vanish after 3 seconds:
<script>
$('div.alert').delay(3000).slideUp(300);
</script>
You could get the individual errors for a field
{!! $errors->first('isbn'); !!}
or you can get all the errors
#foreach ($errors->all() as $error)
<div>{{ $error }}</div>
#endforeach
you can use try catch like this
try{
$books = $request->all();
Book::create($books);
Session::flash('msg', 'Book added!');
}
catch(Exception $e){
Session::flash('msg', $e->getmessage());
}
