Laravel Controller does not recognise an instance class function-CodePudding

I created class which load DB data.

   <?php

namespace App\Repositories;

use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\Log;

class FantasticRepository
{
        private function getFantastic($id)
        {
            $user = Auth::user();
            $companyId = $user->id;
            $tableName = "elites";
            return \DB::table($tableName )->where('id', $id)->first();
       }

}

But a controller can not call a function of the class I created.

use App\Repositories\FantasticRepository;

class FooController extends Controller
{
    private FantasticRepository $fantasticRepository;
    public function getFantastic(Request $request)
    {

       $ke = $fantasticRepository->getInformation($request->id);
      return view('ke.index',compact($ke));
    }
   }

My Error log says

local.ERROR: Undefined variable: fantasticRepository {"userId":4,"exception":"[object] (ErrorException(code: 0): Undefined variable: fantasticRepository at /Users/Developments/abc/app/Http/Controllers/FooController.php:36) [stacktrace] #0 /Users/Developments/app/Http/Controllers/FooController.php(36): Illuminate\Foundation\Bootstrap\HandleExceptions->handleError(8, 'Undefined varia...', '/Users/...', 36, Array)

Is a laravel app able to use an external class?

CodePudding user response：

in Laravel we can import call with use.

use App\Repositories\FantasticRepository;
class FooController extends Controller 
{     
   use FantasticRepository;     
   
   public function getFantastic(Request $request)     
   {         
        $ke = $this->getFantastic($request->id);
        return view('ke.index',compact($ke));     
   }    
}

CodePudding user response：

You need dependency injection. You can do that on constructor or in function argumants.

public function __construct(private FantasticRepository $fantasticRepository) {}

//or

public function getFantastic(Request $request, FantasticRepository $fantasticRepository) {}

CodePudding user response：

You cannot use the private function outside of its class so you have to define getFantastic function as public function to use it in controller

 private function getFantastic($id)
        {
            $user = Auth::user();
            $companyId = $user->id;
            $tableName = "elites";
            return \DB::table($tableName )->where('id', $id)->first();
       }

 public function getFantastic($id)
        {
            $user = Auth::user();
            $companyId = $user->id;
            $tableName = "elites";
            return \DB::table($tableName )->where('id', $id)->first();
       }
