How to share one method to all controllers in Laravel? - laravel

Question

How to share one method to all controllers with different DI, view and parameters? I need something like this:
public function method(Model $model)
{
$baseData = [
'model' => $model,
'route' => route('$route', [$param => $model]),
];
return view($view);
}

All controllers extend App\Http\Controllers\Controller so you can just place it there
<?php
namespace App\Http\Controllers;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Foundation\Auth\Access\AuthorizesRequests;
use Illuminate\Foundation\Bus\DispatchesJobs;
use Illuminate\Foundation\Validation\ValidatesRequests;
use Illuminate\Routing\Controller as BaseController;
class Controller extends BaseController
{
use AuthorizesRequests, DispatchesJobs, ValidatesRequests;
public function method(Model $model, $route, $param, $view)
{
// Declared but not used
$baseData = [
'model' => $model,
'route' => route($route, [$param => $model]),
];
return view($view);
}
}
And use it with $this->method()
For example in HomeController
<?php
namespace App\Http\Controllers;
use App\User;
class HomeController extends Controller
{
/**
* Show the application dashboard.
*
* #return \Illuminate\Contracts\Support\Renderable
*/
public function index()
{
$user = User::first();
return $this->method($user, 'home', 'user', 'welcome');
}
}
Now accessing domain.tld/home will return the welcome view

If you want to share function to all controller best way will make service in service folder of app.
step to make service:-
1.create service using artisan command
php artisan make:service service_name and define function that to share to all controller in your project.
after making service your have to register this service with provider.make a provider using artisan command.
php artisan make provider:provider_name and you will see 2 function register and boot
register function is used to register your created service and boot for call already register service
register service like this
public function register()
{
$this->app->bind('App\Services\servicename', function( $app ){
return new serviceclassname;
});
}
3.Go config folder ,open app.php where you will get providers array. In this provider you have to define you provider like App\Providers\providerclassname::class,
call this service in controllers like use App\Services\serviceclassname;
public function functionname(serviceclassname serviceobject)
{
serviceobject->functionname();
}
