在Laravel开发的电子商务项目中，购物车页面未显示任何内容

问题描述

在我的电子商务项目中，购物车页面不起作用。购物车页面显示为空白页面。我在我的项目中安装了 composer要求“ darryldecode / cart” 的购物车。这是第一个项目，我找不到错误。如果能帮忙解决这个问题，将对您有很大的帮助。

CartController.php

<?php
    
namespace App\Http\Controllers;
    
use Illuminate\Http\Request;
use App\Product;
use App\Category;
    
class CartController extends Controller
{

    public function add(Product $products)
    {
        dd($products);
    
        // add the product to cart
        \Cart::session(auth()->id())->add(array(
         'id' => $products->id,'name' => $products->prod_name,'price' => $products->prod_price,'image' => $products->prod_image_path,'quantity' => 1,'attributes' => array(),'associatedModel' => $products
       ));
       return redirect()->route('products');     
   }
    
   public function index()
   {
        $cartItems = \Cart::Session(auth()->id())->getContent();
        return view('cart')->with(compact('cartItems')); 
    }
}
