I am using Laravel 5.2. I got the following error:
[Symfony\Component\Debug\Exception\FatalErrorException]
Class '\App\Providers\Weixin\WeixinApiProvider' not found
The program runs fine if I move the class file from app/Providers/MyProviders to app/Providers and change the namespace from App\Providers\MyProviders to App\Providers.
But why can't i create the file under app/Providers/MyProviders/ and set the namespace accordingly? Any help?
this is my class file like:
<?php
namespace App\Providers\Weixin;
use Illuminate\Support\ServiceProvider;
class WeixinApiProvider extends ServiceProvider{
/**
* Bootstrap any application services.
*
* #return void
*/
public function boot()
{
//
}
/**
* Register any application services.
*
* #return void
*/
public function register()
{
$this->app->singleton('WeixinApi',function(){
return new \App\Services\WeixinApi();
});
}
}

There is a posting from 2016 that describes how to implement Yasumi:
https://www.yasumi.dev/
into Laravel. But this looks like it completely outdated now. What is the correct way to implement it into Laravel 9?
Post I am referencing from 2016:
https://stackoverflow.com/a/41266340/8207054
I am using this code (AppServiceProvider):
<?php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use Carbon\Carbon;
class AppServiceProvider extends ServiceProvider
{
/**
* Register any application services.
*
* #return void
*/
public function register()
{
$this->app->singleton('yasumi', \Yasumi\Yasumi::create('USA', Carbon::now()->format('Y')));
}
/**
* Bootstrap any application services.
*
* #return void
*/
public function boot()
{
//
}
}
but it causes this error: Illuminate\Container\Container::bind(): Argument #2 ($concrete) must be of type Closure|string|null
You can send function as the second parameter to singleton method like this:
$this->app->singleton('yasumi', function () {
return \Yasumi\Yasumi::create('USA', Carbon::now()->format('Y'));
});
I know there are so many answer, but I cannot really solve this.
I did follow this answer (How to make a REST API first web application in Laravel) to create a Repository/Gateway Pattern on Laravel 5.7
I have also the "project" on github, if someone really kindly want test/clone/see : https://github.com/sineverba/domotic-panel/tree/development (development branch)

use App\Interfaces\LanInterface;
use Illuminate\Database\Eloquent\Model;
class LanRepository extends Model implements LanInterface
{
protected $table = "lans";
public function getAll()
{
return 'bla';
}
}
I did add also App\Providers\RepositoryServiceProvider::class, in providers section of config\app.php
This is finally the controller (I know that it is not complete):
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Gateways\LanGateway;
class LanController extends Controller
{
private $lan_gateway;
/**
* Use the middleware
*
* #return void
*/
public function __construct(LanGateway $lan_gateway)
{
$this->middleware('auth');
$this->lan_gateway = $lan_gateway;
}
/**
* Display a listing of the resource.
*
* #return \Illuminate\Contracts\Support\Renderable
*/
public function index()
{
$this->lan_gateway->getAll();
return view('v110.pages.lan');
}
}
And the error that I get is
Target [App\Interfaces\LanInterface] is not instantiable while building [App\Http\Controllers\LanController, App\Gateways\LanGateway].
I did try:
php artisan config:clear
php artisan clear-compiled
I think #nakov might be right about it being case-sensitive. I don't believe PHP itself cares about upper/lowercase namespaces, but the composer autoloader and the Laravel container use key->value array keys, which do have case-sensitive keys, to bind and retrieve classes from the container.
To ensure the names always match, try using the special ::class constant instead, like this:
<?php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use App\Repositories\LanRepository;
use App\Interfaces\LanInterface;
class RepositoryServiceProvider extends ServiceProvider
{
public function register()
{
$this->app->bind(
LanInterface::class,
LanRepository::class
);
}
}
In my case i forgot to enlist the provider to confit/app.php that's why the error.
Clear the old boostrap/cache/compiled.php:
php artisan clear-compiled
Recreate boostrap/cache/compiled.php:
php artisan optimize
I am trying to understand the packages in laravel which I should be able to upload to github subsequently.
I got everything working except for the controller of my package, haven't worked on views yet.
But I am getting the following error when I visit my localhost website http:\guam.dev\people
ReflectionException
Class Dashboard does not exist
This is my Directory structure.
laravel
-vendor
--student
---people
----composer.json
----src
-----PeopleServiceProvider.php
-----Controllers
------SuperAdmin
-------Dashboard.php
-----Routes
-----Views
This is my PeopleServiceProvider.php
namespace Student\People;
use Illuminate\Support\ServiceProvider;
class PeopleServiceProvider extends ServiceProvider
{
/**
* Bootstrap the application services.
*
* #return void
*/
public function boot()
{
include __DIR__ . '/Routes/routes.php';
$this->loadViewsFrom(__DIR__.'/Views/SuperAdmin/Dashboard', 'People');
}
/**
* Register the application services.
*
* #return void
*/
public function register()
{
$this->app->make('Student\People\Dashboard');
}
}
Controller file : Dashboard.php
namespace Student\People;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
class Dashboard extends Controller
{
/**
* Display a listing of the resource.
*
* #return \Illuminate\Http\Response
*/
public function index()
{
return view('app');
}
}
What am I doing wrong ? I am following an old tutorial, but there isn't much explanation about controllers there.
I've a view composer written like this
view()->composer('masterbox.partials.pipeline', function($view) {
// Some vars and code
});
In one of my view I do as follow
#include('masterbox.partials.pipeline', ['my_var' => 1])
When i'm trying it on my browser everything is fine, but when I run a simple test everything blows up ... After some debugging I found out the closure wasn't executed at all.
$this->visit('/connect/customer/subscribe')
->type($faker->firstName, 'first_name')
->type($faker->firstName, 'first_name')
->type($faker->lastName, 'last_name')
->type($faker->email, 'email')
->type($faker->phoneNumber, 'phone')
->type($password, 'password')
->type($password, 'password_confirmation')
->press("S'inscrire");
Note : It visits a page, fills the form and subscribe, then it redirects on the page with the #include and it returns a big error, part of it is
exception 'ErrorException' with message 'Undefined variable: my_var' in /Users/Loschcode/Google Drive/projects/my_project_lo/website/storage/framework/views/7e11f284c02bc38adc60b5f8a0545df65d7cf5ec.php:7
I'm afraid it an issue, it's a fresh Laravel 5.2 I downloaded a few days ago. Any guess ? Any method to debug this ? Thanks
Working solution
I ended up trying anything. My problem was my service provider organization.
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
class ComposerServiceProvider extends ServiceProvider
{
/**
* Bootstrap the application services.
*
* #return void
*/
public function boot()
{
foreach (glob(app_path().'/Http/ViewComposers/*.php') as $filename){
require_once($filename);
}
}
/**
* Register the application services.
*
* #return void
*/
public function register()
{
//
}
}
If you have a similar organization and problem, replace the require_once by a simple require and everything will go fine.
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
class ComposerServiceProvider extends ServiceProvider
{
/**
* Bootstrap the application services.
*
* #return void
*/
public function boot()
{
foreach (glob(app_path().'/Http/ViewComposers/*.php') as $filename){
require($filename);
}
}
/**
* Register the application services.
*
* #return void
*/
public function register()
{
//
}
}
i have below contract/interface which is binded by a service provider ,however the i get below error :
ReflectionException in RouteDependencyResolverTrait.php line 81:
Class App\Http\Controllers\RocketShipContract does not exist
What am i doing wrong ?
Contract
namespace App\Contracts\Helpers;
Interface RocketShipContract
{
public function blastOff();
}
The concrete class
namespace app\Contracts;
use App\Contracts\Helpers\RocketShipContract;
class RocketShip implements RocketShipContract
{
public function blastOff()
{
return 'Houston, we have ignition';
}
}
The service provider
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use App\Contracts\RocketShip;
class RocketShipServiceProvider extends ServiceProvider
{
protected $defer = true;
/**
* Bootstrap the application services.
*
* #return void
*/
public function boot()
{
//
}
/**
* Register the application services.
*
* #return void
*/
public function register()
{
$this->app->bind('App\Contracts\Helpers\RocketShipContract', function($app){
return new App\Contracts\RocketShip($app['HttpClient']);
});
}
/**
* Get the services provided by the provider.
*
* #return array
*/
public function provides()
{
return ['App\Contracts\Helpers\RocketShipContract'];
}
}
The controller
public function test(RocketShipContract $rocketship)
{
$boom = $rocketship->blastOff();
return view('test.index', compact('boom'));
}
The error you're getting hints at the problem: the class is being resolved in the App\Http\Controllers namespace. That's because you need to specify the full namespace of your interface in the controller.
So either include it with a use statement:
use App\Contracts\Helpers\RocketShipContract;
Or type hint the full namespace:
public function test(App\Contracts\Helpers\RocketShipContract $rocketship)
{
// ...
}
