form validation not working in laravel - php

Question

I am working on laravel 5.3.30 and created a profile page with form and try to validate the data when the form is submitted but I am not getting any errors after submitting the form, its just refresh the page.
Route File:
Route::get('/', function () {
return view('main');
});
Auth::routes();
Route::get('/home', 'HomeController#index');
Route::get('logout', '\App\Http\Controllers\Auth\LoginController#logout');
Route::resource('profile','ProfileController');
Profile Form:
{!! Form::open(array('route'=>'profile.store')) !!}
<div class="form-group">
{{Form::label('first_name','Firstname')}}<span class="required">*</span>
{{Form::text('first_name',null,['class'=>'form-control','placeholder'=>'Enter Firstname'])}}
</div>
<div class="form-group">
{{Form::label('last_name','Lastname')}}<span class="required">*</span>
{{Form::text('last_name',null,['class'=>'form-control','placeholder'=>'Enter Lastname'])}}
</div>
{{Form::submit('Create',array('class'=>'form-submit btn btn-success btn-block btn-lg'))}}
{!! Form::close() !!}
Validation in Profile Controller:
public function store(Request $request)
{
$this->validate($request,array(
'first_name'=>'required|max:255',
'last_name'=>'required|max:255'
));
}
When I submit the form without filling anything, it just refresh the page and does not show any errors. Please suggest something. Thanks in advance.

Answer 1

It looks like you forget to send error from controller and print in view.
here is controller code should look like
public function store(Request $request)
{
$this->validate($request,array(
'first_name'=>'required|max:255',
'last_name'=>'required|max:255'
));
// include this line incase of validation error
return $validator->errors()->all();
}
You need to print error in view in order to know user
#if (count($errors) > 0)
<div class="alert alert-danger">
<ul>
#foreach ($errors->all() as $error)
<li>{{ $error }}</li>
#endforeach
</ul>
</div>
#endif
