所以我一直在做一个网站，我试图制作一个带有结账系统的功能性购物车。但是，购物车不允许在 Mozilla Firefox 中删除添加的项目，在其他浏览器上它运行良好；我不知道为什么会这样。
此外，我的第二个问题是，在 checkout.php 函数中，每当我在购物车页面中按下结帐按钮时，它不会将订单电子邮件发送到业务电子邮件。有什么办法可以让我完成这项工作吗？下面我已经把所有必要的代码。谢谢你。
购物车.php：
<link rel="stylesheet" href = "styles/styling.css" media="all" />
<?php
session_start();
include("adminarea/includes/DBcon.php");
include ("functions/php1.php");
include ("header.php");
require 'obj.php';
?>
<body>
<?php
//Fetches information from the database and displays them with the help of obj.php
if(isset($_GET['pID'])){
$res = mysqli_query($connection, 'select * from product where pID='.$_GET['pID']);
$prod = mysqli_fetch_object($res);
$obj = new obj();
$obj->pID = $prod->pID;
$obj->pName = $prod->pName;
$obj->pPrice = $prod->pPrice;
$obj->qty = 1;
//to check if products exists in cart or not
$index = -1;
$cart = unserialize(serialize($_SESSION['cart']));
for($i=0;$i<count($cart);$i++)
if($cart[$i]->pID==$_GET['pID'])
{
$index = $i;
break;
}
if($index==-1)
$_SESSION['cart'][] = $obj;
else{
$cart[$index]->qty++;
$_SESSION['cart']=$cart;
}
echo "
<script>
window.open('cart.php','_self')
</script>
";
}
if(!(isset($_SESSION['cart']))){
echo "
<script>
alert('Shopping cart is empty!')
</script>
";
echo "
<script>
window.open('products.php','_self')
</script>
";
}
//if statement to delete the chosen product inside the cart
if(isset($_GET['index']))
{
$cart = unserialize(serialize($_SESSION['cart']));
unset ($cart[$_GET['index']]);
$cart = array_values($cart);
$_SESSION['cart'] = $cart;
}
?>

结帐.php：
<?php
//starting the session
session_start();
$from = "[email protected]"; //from
$feedback = "Purchase details";
$to = "[email protected]";//direction
$email = "Email from: $from \r\n";
mail("[email protected]", $feedback, $from);
header("Location: index.php"); //returns the user back to homepage
echo "
<script>

</script>
";
?>
在我看来你的mail()电话是不正确的
参数的顺序应该是：地址、主题、电子邮件正文，然后是发件人。发件人应采用以下格式From: [email protected]
因此，将您的代码调整为如下所示：
$from = "[email protected]"; //from
$feedback = "Purchase details";
$to = "[email protected]";//direction
$email = "Email from: $from \r\n";
mail($to, $feedback, $email, "From: $from");
