I am trying to register events with the service provider but I keep getting reflection class error. I have searched and could not find a solution, perhaps this is an issue with the core.
// AppServiceProvider.php
<?php namespace App;
use Illuminate\Support\ServiceProvider;
use App\Events\UserEventHandler;
class AppServiceProvider extends ServiceProvider {
public function register() {
// Events
$this->app->events->subscribe(new UserEventHandler);
}
}
// UserEventHandler.php
<?php namespace App\Events;
class UserEventHandler {
/**
* Handle user login events.
*/
public function onUserLogin($event)
{
echo 'subscriber logged in'; exit;
}
/**
* Register the listeners for the subscriber.
*
* #param Illuminate\Events\Dispatcher $events
* #return array
*/
public function subscribe($events)
{
$events->listen('auth.login', 'UserEventHandler#onUserLogin');
}
}
$this->app->events->subscribe(new UserEventHandler); is firing fine, because I can reach the subscribe method, however $events->listen('auth.login', 'UserEventHandler#onUserLogin'); is returning an exception Class UserEventHandler does not exist
I have tried the same code on global.php and works fine, so the problem lies on the ServiceProvider, I have tried both methods register() and boot() and get the same error.
[UPDATED]
I have found that you need to specifically specify the full namespace when listening for the event.
public function subscribe($events)
{
$events->listen('auth.login', 'App\Events\UserEventHandler#onUserLogin');
}
You need to declare the full path to the class if it is in a different directory to the service provider.

I'd like to share data with all views via the AppServiceProvider. Moreover, I'd like to check the guard type first to give some specific output for each user type.
I tried to check the guard in AppServiceProvider via Auth::guard('admin')->check() but it returns false. However, the same if statement works perfectly in my Controllers.
I've also included Illuminate\Support\Facades\Auth and Illuminate\Support\Facades\View.
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\View;
class AppServiceProvider extends ServiceProvider
{
public function boot()
{
if (Auth::guard('admin')->check()) {
// Share data with views
}
}
}
The if statement returns false, although I'm logged in as admin.
you need view composer for this.
<?php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use Auth;
use DB;
class AppServiceProvider extends ServiceProvider
{
/**
* Bootstrap any application services.
*
* #return void
*/
public function boot()
{
view()->composer('*', function ($view)
{
if (Auth::guard('admin')->check()) {
}
});
}
/**
* Register any application services.
*
* #return void
*/
public function register()
{
//
}
}
If you want to pass data in views.
view()->composer('*', function ($view)
{
if (Auth::guard('admin')->check()) {
$admin = DB::table('admins')->first(); // for example
$view->with(compact('admin'));
}
});
I'm trying to apply a sort of "repository-pattern" to a custom service.
What I'd like to do is to actually bind this library to my custom service provider to create an abstraction layer and, eventually, switch that library with another one in the future.
I'm trying to move the 'providers' and 'aliases' references from config/app.php to my service provider, but I get a Class 'GoogleMaps' not found error.
I've added App\Providers\GeoServiceProvider::class to config/app.php providers array and this is my relevant code:
GeoServiceProvider.php(my custom service provider)
<?php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
class GeoServiceProvider extends ServiceProvider
{
/** * Register services.
*
* #return void
*/
public function register()
{
$this->app->bind(\App\Interfaces\GeoInterface::class, \App\Services\GoogleGeoService::class);
$this->app->alias(\GoogleMaps\Facade\GoogleMapsFacade::class, 'GoogleMaps');
}
/**
* Bootstrap services.
*
* #return void
*/
public function boot()
{
}
}
GeoInterface.phpinterface defining standard methods
<?php
namespace App\Interfaces;
interface GeoInterface
{
public function geoCode();
}
GoogleGeoService.php(The actual library implementation)
<?php
namespace App\Services;
use App\Interfaces\GeoInterface;
class GoogleGeoService implements GeoInterface
{
public function geoCode()
{
$response = \GoogleMaps::load( 'geocoding' ) <--- HERE IS WHERE I GET THE ERROR
->setParamByKey( 'latlng', "45.41760620,11.90208370")
->setEndpoint( 'json' )
->get();
$response = json_decode($response, true);
return $response;
}
}
TestController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Interfaces\GeoInterface;
class TestController extends Controller
{
protected $geoService;
public function __construct(GeoInterface $geoService) {
$this->geoService = $geoService;
}
public function index() {
return $this->geoService->geoCode();
}
}
Thank you,

I have setting options which has controller and I need to get some of it's data on header and footer which need to be load globally.
How do I do that?
I've read some questions in this website but none of them helped me as I expected, or I didn't get those! either way I need your help to solve this issue of mine.
Thanks.
there are many ways to do that
but one of them that refer in laravel document is using boot
Sharing Data With All Views
Occasionally, you may need to share a piece of data with all views
that are rendered by your application. You may do so using the view
facade's share method. Typically, you should place calls to share
within a service provider's boot method. You are free to add them to
the AppServiceProvider or generate a separate service provider to
house them:
<?php
namespace App\Providers;
use Illuminate\Support\Facades\View;
class AppServiceProvider extends ServiceProvider
{
/**
* Bootstrap any application services.
*
* #return void
*/
public function boot()
{
View::share('key', 'value');
}
/**
* Register the service provider.
*
* #return void
*/
public function register()
{
//
}
}
you can share a variable inside boot method of AppServiceProvider.php
for example you have categories table and Category Model and you want to share it to all views
<?php
namespace App\Providers;
use Illuminate\Support\Facades\View;
class AppServiceProvider extends ServiceProvider
{
/**
* Bootstrap any application services.
*
* #return void
*/
public function boot()
{
$categories = Category::All();
View::share('categories', 'categories');
}
/**
* Register the service provider.
*
* #return void
*/
public function register()
{
//
}
}
but if you want to have header and footer for your site simply you can use master file and extend it to other views
document
Getting issue with Laravel Observer
I created a user observer when i'm doing api call in order to fetch single user also i'm getting list of all user exist in table. what i'm doing wrong.
Here my ObserverProvider and UserObserver which i register in app.php
ObserversServiceProvider
namespace App\Providers;
use App\User;
use App\Observers\UserObserver;
use Illuminate\Support\ServiceProvider;
class ObserversServiceProvider extends ServiceProvider {
/**
* Bootstrap the application services.
*
* #return void
*/
public function boot() {
User::observe(UserObserver::class);
}
/**
* Register the application services.
*
* #return void
*/
public function register() {
}
}
UserObserver
namespace App\Observers;
use App\User;
class UserObserver
{
/**
* Listen to the User created event.
*
* #param User $user
* #return void
*/
public function created(User $user) {
// doing something
}
}
I'm getting list of all user when i'm doing.
$user = User::where('user_id',1)->first();
I've set up a package in laravel 4 via the artisan workbench command. I created a facade class and followed this tutorial to come up with the following service provider, facade and root classes:
src/Spoolphiz/Infusionsoft/InfusionsoftServiceProvider.php:
namespace Spoolphiz\Infusionsoft;
use Illuminate\Support\ServiceProvider;
class InfusionsoftServiceProvider extends ServiceProvider {
protected $defer = false;
/**
* Bootstrap the application events.
*
* #return void
*/
public function boot()
{
$this->package('spoolphiz/infusionsoft');
}
/**
* Register the service provider.
*
* #return void
*/
public function register()
{
// Register 'infusionsoft' instance container to our Infusionsoft object
$this->app['infusionsoft'] = $this->app->share(function($app)
{
return new Spoolphiz\Infusionsoft\Infusionsoft;
});
}
/**
* Get the services provided by the provider.
*
* #return array
*/
public function provides()
{
return array();
}
}
src/Spoolphiz/Infusionsoft/Facades/Facade.php:
namespace Spoolphiz\Infusionsoft\Facades;
use Illuminate\Support\Facades\Facade;
class Infusionsoft extends Facade {
/**
* Get the registered name of the component.
*
* #return string
*/
protected static function getFacadeAccessor() { return 'infusionsoft'; }
}
Finally I've set up the underlying class thats to be connected to the facade at src/Spoolphiz/Infusionsoft/Infusionsoft.php:
namespace Spoolphiz\Infusionsoft;
//use Spoolphiz\Infusionsoft\iSDK;
/*
This is hackish and a un-laravel way to handle the requirement of \iSDK but unfortunately the xmlrpc3.0 lib doesn't want to correctly encode values when run with a namespace. Will try to resolve this later.
*/
require_once(__DIR__.'/isdk.php');
class Infusionsoft extends \iSDK {
protected $_app;
/**
* Init the sdk
*
*/
public function __construct( $connectionName )
{
$this->_app = parent::cfgCon($connectionName);
}
public function test()
{
dd('works');
}
}
I set up the service provider and the facade alias of Infusionsoft in app/config/config.php.
When I try running methods belonging to the extended iSDK class against an instance of Spoolphiz\Infusionsoft\Facade\Infusionsoft I get undefined method errors, such as the following:
Call to undefined method Spoolphiz\Infusionsoft\Facades\Infusionsoft::loadCon()
Why is this? The whole point of facades is to be able to call methods against its root class...
Looks like I was being stupid. I was developing this package in the laravel workbench. Once it was done I submitted it to packagist and set up a requirement for it in the same laravel app. Having the package installed in vendors directory and in the workbench caused some sort of conflict.
Lesson learned: make sure you dont have the same package in your workbench and in your application's vendors directory.
