How can I see that validation fulfills and its rules are in effect,
But I do not see the display of validation errors when it is not passed and the data in the input fields when the Form is filled when redirecting back.

Answer 1

Let me show you my method which also uses validation on Laravel 5.2 and find out what the difference you have with this code:
The Controller which handles the request:
$validator = \Validator::make($request->all(), [
'data1' => 'required',
'data2' => 'required|in:bla1,bla2,bla3',
'data3' => 'required|array',
'data3.*' => 'required|json',
'data4' => 'required_if:data2,bla2',
]);
if ($validator->fails()) {
$request->flash();
return \Response::make(\View::make('theform')
->withErrors($validator)
->withInput($request->all())
->render()
, 406);
}
The form which contains the form which has been submitted and redrawn with error logs, named 'theform':
<input type="text" class="form-control" name="trip_name" id="trip_name"
placeholder="Gezi ismi" value="{{ old('trip_name') }}">
#if ($errors->has('trip_name'))
<span class="help-block">
<strong>{{ $errors->first('trip_name') }}</strong>
</span>
#endif
This is one way to show it. You can also view it your way as:
#if( count($errors) > 0 )
<div class="alert alert-danger">
<ul>
#foreach( $errors->all() as $error )
<li>{{ $error }}</li>
#endforeach
</ul>
</div>
#endif

Answer 2

Well, the problem did not stop there ))
I create the validation through my own class Request and divide routes for GET and POST and defined separate methods for them in my Controller.
1. app/Http/routes.php
Route::get('/contact_form/{prm?}', ['uses'=>'Admin\ContactformController#show_form_get'])->name('contact_form');
Route::post('/contact_form', ['uses'=>'Admin\ContactformController#show_form_post']);
2. app/Http/Requests/ContactRequest.php - my custom Request class with validation rules:
<?php
namespace App\Http\Requests;
use App\Http\Requests\Request;
class ContactRequest extends Request
{
public function authorize()
{
return true; //false
}
public function rules()
{
return [
'name' => 'required|max:10',
//'name' => 'exists:users,name',
'email' => 'required|email',
'site'=>'required',
];
}
} //__/class ContactRequest
3. app/Http/Requests/ContactRequest.php - my Controller with POST and GET handling:
<?php
namespace App\Http\Controllers\Admin;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Requests\ContactRequest; //custom Request class with validation rules
use App\Http\Controllers\Controller;
use \Illuminate\Support\Facades\Validator;
class ContactformController extends Controller {
public $show_controller_method = array(__METHOD__);
/** Method handler http-request with GET
*/
public function show_form_get( ){
$this->show_controller_method[] = 'showform()';
if( view()->exists('default.contact_form') ){
return view('default.contact_form')->withInfoMethodController($this->show_controller_method);
}
else { abort(404); }
} //__/public function show_form_get()
/** Method handler http-request with POST
*/
public function show_form_post( ContactRequest $request ){
if( $request->isMethod('post') ):
dump( $request->all() );
endif;
}
3. The view remained the same and there is a return of data "old inputs":
value="{{ old('name') }}" value="{{ old('email') }}" and so on...
and errors of validation if they exist:
#if( count($errors) > 0 )
<div class="alert alert-danger">
<ul>
#foreach( $errors->all() as $error ) <li>{{ $error }}</li> #endforeach
</ul>
</div>
#endif
Now the validation works (if it passes successfully - I see a dump() the POST.
If the validation falls, then a redirect occurs, but there are no validation errors and there are no old inputs.
Tell me please what I'm doing is not right?
