            return view('user.home',compact('data', $data));
        }
        
    }
}

and my Route :

Route::get('/', [HomeController::class, 'index']);

Please help me

Answer 1

Please remove $data from compact() function

 return view('user.home',compact('data'));

You passed the variable ‍$data‍ to the ‍‍‍‍view('user.home', compact('data')) but you have an error in the product.blade I think the problem is on the product. blade file. check that file

Answer 2

You error is in the product.blade.php view and in your controller you're returning the home.blade.php view.

You can avoid the Undefined variable error in your product.blade.php adding an isset in your view like this :

@if(isset($data))
   @foreach($data as $product)
       (...)
   @endforeach
@endif
