Question

我想从两个表中添加产品，一个来自项目，另一个来自子项目。但是当我尝试从相关的父项添加子项时。父项本身已添加到购物车中。数量变成双倍。冲突是......让我们假设父母的产品有id = 1,2,3，...... 在子表中也有产品也具有相同的id＆s; s = 1,2,3，... 当我尝试添加id = 1的产品时。它将其作为父项并添加数量为double的相同父产品。我不知道如何解决这个问题。我真的对此感到沮丧。请看下面的代码。子项目的方法如下！

public function show($s)
 {
   $sId = Item::find($s);
   Cart::add($sId->id,$sId->sub_title,1,$sId->sub_price);
   return back();
 }

来自父项的方法如下：

public function edit($mealId)
{
  $getId = Menu::find($mealId);
  Cart::add($getId->id,$getId->title,1,$getId->price);
  return back();
}

在购物车索引页面上：

 @extends('layouts.app')

@section('title', 'Cart')
<style media="screen">
a.cross-btn:link{
  text-decoration: none;
}
div.cart-section{
  width: 100%;
  height: auto;
  padding: 40px 25px;
}
</style>
@section('body')

<div class="container">

向购物车添加多个商品时，add（）方法将返回CartItems数组。
