Laravel foreach所有產品的總價

Question

在 Laravel 中，如果我想獲取購物車中所有產品的總價，我應該在我的代碼中添加什么？ 這是 cart.blade.php 文件：

@extends('layouts.app')
@section('content')

<main class="container">

  <section class="row justify-content-center">

   <h1 class="text-center mb-5">Products on your cart:</h1>

  </section>

  <section class="row justify-content-center">

  @foreach(Auth::user()->computers()->get() as $computer)

  <div class="col-12 col-md-4">

   <h2 class="text-center">{{$computer->name}}</h2>
   <img class="card-img-top" src="{{Storage::url($computer->img)}}" alt="">
   <form action="{{route('computers.removepc',['id'=>$computer->id])}}" method="POST">
   @csrf 
   <center><button class="btn btn-danger mb-5" type="submit">Remove</button></center>
   <p class="text-center">Price: {{$computer->price}}</p> //This is the single price of each product

   </div>

 @endforeach


 </section>

 <section class="row justify-content-center">
  <h1>Here I want the total price</h1> //Here is , for example, where i want the total price of all computers in the cart
 </section>

 </main>
 @endsection

感謝幫助！

嘗試在@foreach 上方添加 $total 變量，如下所示：

<?php $total = 0; ?>

然后在@foreach 中添加以下內容：

 <?php $total+= $computer->price  ?>

然后go到你想要的地方output總寫：

   {{$total}}
