            </tr> @endforeach </tbody>
    </table>
    <form action="{{route('store.product.create')}}" method="GET">

    </form>
@endsection

这是我的控制器页面：

<?php

namespace App\Http\Controllers;

use App\Models\Category;
use App\Models\Product;
use Illuminate\Http\Request;

class ProductController extends Controller {
    /**
     * Display a listing of the resource.

        return view('product.index',$data);
    }
    
    /**

     * @return \Illuminate\Http\Response
     */
    public function create() {
        $category=array( 'category' =>Category::all() );
        return view('home',$category);
    }
    
    /**
     * Store a newly created resource in storage.

    public function store(Request $req) {
        $product =new Product();

        $product->Product_code= $req->input('Product_code');
        $product->Category_id= $req->input('Category_id');
        $product->save();
        return redirect()->route('store.product.index',['products'=>$product->id]);
    }
    
    /**
     * Display the specified resource.
     * @param int $id
     * @return \Illuminate\Http\Response
     */
    public function show($id) {
        $category=array( 'category' =>Category::all() );
        return view('product.show',$category, ['product' => Product::findOrFail($id)]);
    }
    
    /**

    }

    /**

    public function update(Request $request) {
        $product=Product::find($request->id);
        $product->Product_name=$request->input('Product_name');
        $product->Product_description= $request->input('Product_description');
        $product->Product_image= $request->input('Product_image','public');
        $product->Product_code= $request->input('Product_code');
        $product->Category_id= $request->input('Category_id');
        $product->save();
        return redirect()->route('store.product.index', ['product'=> $product->id]);
    }

    public function destroy($id) {
        $product = Product::findOrFail($id);
        $product->delete();
        echo ("User Record deleted successfully.");
        return redirect()->route('product.index');
    }
}
