我是这方面的初学者，我提前道歉。我整晚都在冲浪，试图找到问题的答案。然后我看到了这个程序员平台。
这是我的问题，我的函数运行得很好。我有这个购物车，用户可以选择许多产品并提交它。但它只向我的数据库中插入一个值。有人能帮我吗？

1( 假设您使用$_POST['submitbtn']验证购物车，看起来您只是在插入一个产品。
2( 如果您已经将产品存储在卡库中，为什么要从$_POST接收产品？
也许这会有所帮助：
foreach($this->cart->contents() as $items)
{
$data = array(
"product_name" => $items["name"],
"quantity" => $items["qty"],
"product_price" => $items["price"]
);
$this->db->insert('occasion', $data);
}
