Hello i found solution
if you work on yii2 advanced template so components can`t put in "root directory" if you put so class not found error get
so solution is if you work on "frontend" so components put in that directory then used custom widget it will works ;)

I am working on a requirement of where I have to include all common methods like pagination, etc. which were used in my views into all my views. For this purpose I thought helper file is useful and created helper file in common\helpers\ directory with name Common as helper file name. I am facing difficulty in using this helper file in my view file.
I have included this helper file in my view as
use common\helpers\Common;
When I open the page I am getting error as "Class 'common\helpers\Common' not found"
My helper file: Common.php
namespace common\helpers;
class Common
{
protected $_file;
protected $_data = array();
public function __construct($file)
{
$this->_file = $file;
}
public static function getCommonHtml($id=NULL)
{

}

}
I googled for this & got few solutions but they never worked.
You need to declare your new namespace in your composer.json:
"autoload": {
"psr-4": {
...
"common\\": "common/"
}
},
And the run:
composer dump-autoload
Alternatively you could declare alias for new namespace, so Yii autoloader will handle it (like in advanced template):
Yii::setAlias('#common', dirname(__DIR__))
But Yii autoloader will be dropped in Yii 2.1, so I would stick to composer-way (or do both - alias may be useful not only for autoloading).
I created a service provider named AdminServiceProvider
namespace App\Providers;
use Modules\Orders\Models\Orders;
use Illuminate\Support\ServiceProvider;
use View;
class AdminServiceProvider extends ServiceProvider
{
public function boot()
{
$comments = Orders::get_new_comments();
View::share('comments', $comments);
}
public function register()
{
}
}
Registered the provider
App\Providers\AdminServiceProvider::class,
Now I try to attach it to the controller
namespace App\Http\Controllers\admin;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use App\Providers\AdminServiceProvider;
class AdminController extends Controller
{
public $lang;
public function __construct()
{
}
public function index(){
return view('admin/dashboard');
}
}
Now I get this error message
Undefined variable: comments
This is the first time I try to use a custom service provider and don't know exactly how it works I'm sure there's something missing Hope you can help. Thanks in advance.
[UPDATE]
removed use App\Providers\AdminServiceProvider; from the controller
php artisan clear-compiled solved the problem but I want to attach it to some controllers not all controllers as the $comments are sent to all contollers in my app. So how to attach the service provider to specific controllers not all of them?
For the undefined variable run: php artisan clear-compiled will solve it
If you want to share a variable in some of your views you can create a middleware and assign it to the views you want to share the data with:
First create a middleware: php artisan make:middleware someName
Then in the handle function you add your view sharing logic:
$comments = Orders::get_new_comments();
view()->share('comments',$comments);
return $next($request);
Then register your middleware under the $routeMiddleware array and
give it an alias.
Then attach it to your routes like:
Route::group(['middleware'=> 'yourMiddlewwareName'], function(){
//your routes
});
If you have all your admin views in one directory (views\admin for example) you can use view composer in AdminServiceProvider:
public function boot()
{
view()->composer('admin.*', function($view){
$view->with('comments', Orders::get_new_comments());
});
}
It will attach comments variable to each view in your views\admin directory.
You can also attach a variable to some specific views or folders like this:
view()->composer(['admin.posts.*', 'admin.pages.index'], function($view){
$view->with('comments', Orders::get_new_comments());
});
I'm trying to load a listener but symfony keeps throwing this error:
ClassNotFoundException in appDevDebugProjectContainer.php line 1783:
Attempted to load class "CommandeListener" from namespace "Louvre\ReversationBundle\Services\Listeners".
Did you forget a "use" statement for another namespace?
My class is properly writen (i guess):
<?php
namespace Louvre\ReservationBundle\Services\Listeners;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Component\HttpKernel\Event\FilterResponseEvent;
class CommandeListener {
public function checkCommand(FilterResponseEvent $event){
if (!$event->isMasterRequest() && $event->getRequest()->get('_route') == "louvre_reservation_step1") {
return;
}
$url = $this->router->generate("louvre_reservation_step1");
$response = new RedirectResponse($url);
$event->setResponse($response);
}
}
Its path is
src/Louvre/ReservationBundle/Services/Listeners/CommandeListener.php
and here is the yaml service
louvre_reservation.commande.listener:
class: Louvre\ReversationBundle\Services\Listeners\CommandeListener
tags:
- { name: kernel.event_listener, event: kernel.request, method: checkCommande }
I have other services which work perfectly.
they are declared the same way.
I googled the problem but could not find an answer.
Does anyone already faced this problem?
Thanks in advance
It looks like you made a typo in your class include. You wrote "Reversation" instead of "Reservation" which make your code looks into the "Reversation" folder which does not exists.
I have a controller that calls a helper class in my app/helpers directory and then that helpers calls another class within it's namespace, but it can't find that class.
So here is my controller:
<?php
namespace App\Controllers\Dash;
use \App\Models\SalesFlyer;
use \App\Helpers\MyPdf;
class FlyerBuilderController extends BaseController {
public function getPdf($flyerId = null) {
$flyer = new SalesFlyer();
$flyerData = $flyer->getSalesFlyerName($flyerId);
$flyerPath = public_path().'/assets/media/flyers/'.Session::get('userid').'/'.$flyerData->name.'-'.$flyerId.'.html';
return MyPdf::downloadPdf($flyerPath, $flyerData->name);
}
}
It catches MyPdf class perfectly fine. Here is MyPdf class:
<?php
namespace App\Helpers;
class MyPdf {
public static function downloadPdf($filePath, $filename) {
$client = new PdfCrowd("anthonythomas", "1ebd0d6e3ec1dfa83a6c5f3dd32906f0");
// other code here
}
}
The PdfCrowd class is within App\Helpers namespace like so:
<?php
namespace App\Helpers;
//
// Pdfcrowd API client.
//
class PdfCrowd { }
Class 'App\Helpers\PdfCrowd' not found
Here is my start/global.php file:
<?php
ClassLoader::addDirectories(array(
app_path().'/commands',
app_path().'/controllers',
app_path().'/controllers/dash',
app_path().'/controllers/dash/product',
app_path().'/models/Product',
app_path().'/models',
app_path().'/database/seeds',
app_path().'/helpers',
));
Then here is my composer:
"autoload": {
"classmap": [
"app/commands",
"app/controllers",
"app/controllers/dash",
"app/controllers/dash/product",
"app/models",
"app/models/Product",
"app/helpers",
"app/database/migrations",
"app/database/seeds",
"app/tests/TestCase.php"
]
}
Any idea why I'm getting that error?..
Everything looks fine but you also have to remember to
composer dump-autoload
Every time you create a new class. Also, check the file
vendor/composer/autoload_classmap.php
You must see your Helper class there.
But if you use PSR-4, you can use the same namespace and you won't have execute composer dump-autoload again:
"autoload": {
"psr-4": {
"App\\Helpers\\": "app/helpers"
}
},
Just remember to remove "app/helpers", from the classmap.
Ok for a shared hosting provider... EVERYTIME you add a new namespace and update composer even with psr-4 it seems, you have to replace the vendor directory with the current one on your local machine for it to actually go through! This saved me so much hours of time after I realized I had to replace the vendor directory everytime a composer dump-autoload was issued locally.
This is the problem: I haven't be able to load a class from a namespace.
I'm developing a restful app and I'm trying to follow the Entity/Service/Repository way to access and give format to the requested data. The thing is that I cannot load any class from Services. I have created a folder inside my app called api, and within it the others 3 folders: api/entities/, api/services/ and api/repositories/. There are 2 more folders inside services: validators and datapickers.
As it is a RESTulf app, I also created an api folder inside the controllers folde: controllers/api/.
Here is the the current tree of my app folder:
app/
api/
entities/
repositories/
services/
datapickers/
MemberData.php
ConsumeData.php
validators/
...
models/
controllers/
api/
members.php
(other restful controllers)
languages/
...
In first instance, this is my Autoload section from start.php:
Autoloader::directories(array(
path('app').'models',
path('app').'libraries',
path('app').'api'
));
Autoloader::namespaces(array(
'Api' => path('app').'api',
));
And this is MemberData.php:
<?php
namespace Api\Services\Datapickers;
use Api\Repositories as Repo;
class MemberData
{
/* Do some stuff */
}
Now, when I try to use MemberData in controllers/api/members.php:
<?php
use Api\Services\Datapickers\MemberData;
class Api_Members_Controller extends Api_Base_Controller
{
public function get_index($id = null)
{
if (!empty($id))
$this->params->data = MemberData::getById($id);
else
{
$this->params->data = MemberData::getAll(
Input::get('offset'),
Input::get('limit')
);
}
return Response::json($this->params, 200);
}
}
I get the following:
Unhandled Exception
Message:
Class 'Api\Services\Datapickers\MemberData' not found
Location:
/path_to_project/application/controllers/api/members.php on line 15
which is this line: $this->params->data = MemberData::getById($id);
I autoload the api folder and register the base api namespace in start.php but I still keep receiving the same error. IT's like Laravel doesn't recognize the api namespace or something like that.
I tried to register the full namespace:
Autoloader::namespaces(array(
'Api\Services\Datapickers' => path('app').'api/services/datapickers',
));
but the error I got was: Call to undefinde method 'Api\Services\Datapickers\MemberData::getById()'. This was just a test (I don't want to register every sub-namespace in the Autoloader).
