我正在使用JavaScript购物车。现在，我想使用php通过Gmail将购物车详细信息发送给管理员。 我无法从购物车中提取数据并将其组合在邮件的邮件正文中。 我现在知道要发送电子邮件。 我不想使用数据库，也不想使用会话来管理我的购物车。 下面是我的代码。请帮忙！

从快速阅读您的代码开始，我觉得您需要更改：
const handleClick=()=>{ alert(item_name.current.value)}
具有：
function displayCart() {
var cartArray = shoppingCart.listCart();
...
我什么也没尝试，所以也许我没抓住重点，在这种情况下，我道歉。

使用功能或控制名称，图标和价格以及详细信息的JavaScript发送电子邮件（需要添加2），但我唯一建议不要为此使用php，因为这样做会很困难您需要添加很多代码。...如果这对不起您，对javascript不好。
更新！！！ 您不能使用javascript发送直接电子邮件；（请勿使用php来做一个简单的管理面板并添加功能，因此当单击购买时，它将发送您使用javascript添加的功能，因此这将使一切变得超级简单，并且不要添加登录到管理面板只需为该域创建一个私有域，并使其类似于/ products / admin / adminpanel / admin / registers / product / productview @ siteadmins123
或者ldk只是用非常简单的代码制作一个登录页面，因为99.9％的人不会再这样考虑
