查看商城源码时 看到的做下笔记
文件包括: test.php,cart.php
一. test.php(商品显示页面)
<?php
$cart_list = !empty($_COOKIE['cart_list'])?unserialize($_COOKIE['cart_list']):array();
//例子使用数组实际会用mysql
$product_list = array(
array(
'pid' => 1,
'name' => '商品1号',
'money' => '10.5元',
'logo' => ''
),
array(
'pid' =>2,
'name' => '商品2号',
'money' => '23.5元',
'logo' => ''
)
);
?>

<?php endforeach; ?>

</body>
</html></span>
<?php
header('Content-type:text/html; charset=utf-8');
//查看cookie里面有没有购物车数据 有就返回序列化后的结果
$cart_list = !empty($_COOKIE['cart_list'])?unserialize($_COOKIE['cart_list']):'';
if(isset($_POST['id']) && isset($_POST['product'])){
$id = $_POST['id']; //给每个商品ID一个数组来保存数据
$cart_list[$id]['name'] = $_POST['product'];
$cart_list[$id]['id'] = intval($id);
$cart_list[$id]['time'] = time();
//设置cookie保存购物车
setcookie('cart_list', serialize($cart_list), 0, '/');
