如何從URL傳遞變量DBcontroller

Question

我在Laravel新我嘗試這樣做：

路由器

Route::get('productdetails/{id}', function($id){ 
'ProductDetailsController@productdetails' .$id; 

}）;

ProductDetailsController

<?php 

namespace App\Http\Controllers; 

use Illuminate\Http\Request; 
use DB; 
use App\Http\Requests; 
use App\Http\Controllers\Controller; 

class ProductDetailsController extends Controller 
{ 
    public function inventory(){ 
    $inventory = DB::select('select * FROM inventory WHERE barcode = ?', [$id]);; 
    return view('productdetails',['inventory'=>$inventory]); 
    } 
} 

和我：

NotFoundHttpException在RouteCollection.php線161：

路線正確的語法是：

Route::get('productdetails/{id}', 'ProductDetailsController@inventory'); 

和方法應該是這樣的：

public function inventory($id) 
{ 
    ....
