每次单击“添加到购物车”按钮时，如何在会话数组中添加值？

Question

每次我点击添加购物车按钮我都会传递一个id值并从数据库中获取数据，我想保存一个会话数组。

<?php session_start() ?>
<?php require 'config.php' ?>
<?php 
  if (isset($_POST['id'])) {
    $sql = "SELECT product_name, product_price FROM products WHERE id=".$_POST['id'];   
    $result = $mysqli->query($sql) or die($mysqli->error);

    $result = $result->fetch_assoc();

    if (isset($_SESSION['cart'])) {
        if (isset($_SESSION['cart']['id'])) {
            unset($_SESSION['cart']['id']);
        }
    }

    $_SESSION['cart']['id'] = $result;

    $cart = count($_SESSION['cart']);
    //$cart = json_encode($_SESSION['cart']['id']);

    echo $cart;
  }
?>

尝试这样的事情：

.no-scroll::-webkit-scrollbar {display:none;}
.no-scroll::-moz-scrollbar {display:none;}
.no-scroll::-o-scrollbar {display:none;}
.no-scroll::-google-ms-scrollbar {display:none;}
.no-scroll::-khtml-scrollbar {display:none;}

section {
    ...
    overflow-x: scroll;
    -ms-overflow-style: -ms-autohiding-scrollbar;
}
