Php 从数组中获取项并将其放入数据库,php,arrays,Php,Arrays,我仍在学习，如果这很简单，我很抱歉。。。我试图实现的是一个在线商店结账系统（别担心，它不会被使用，它只是为了我自己的学习，所以任何草率的代码都不会影响一个贫穷的企业主，但是任何草率的代码都是值得赞赏的） 因此，我让客户选择产品，然后将其存储在阵列中，并显示在篮子中。然后，我想将用户带到一个签出页面，这样他们可以单击“订单”，然后将这些项目连同他们的用户名一起更新到数据库中的“订单”表中 我仍在掌握数组（可能是我所处学习阶段的标识符），因此当我有几个不同的数组时，我不确定如何将这些项目（基本上只是

我仍在学习，如果这很简单，我很抱歉。。。我试图实现的是一个在线商店结账系统（别担心，它不会被使用，它只是为了我自己的学习，所以任何草率的代码都不会影响一个贫穷的企业主，但是任何草率的代码都是值得赞赏的）

因此，我让客户选择产品，然后将其存储在阵列中，并显示在篮子中。然后，我想将用户带到一个签出页面，这样他们可以单击“订单”，然后将这些项目连同他们的用户名一起更新到数据库中的“订单”表中

我仍在掌握数组（可能是我所处学习阶段的标识符），因此当我有几个不同的数组时，我不确定如何将这些项目（基本上只是ISBN编号和价格）从我的购物篮带到结账页面。我要做的是展示我是如何创建每个数组的，以及我是如何在篮中显示它的，希望这将是您可能需要的一切！非常感谢您的阅读，我们将非常感谢您的帮助。。我希望这个问题也能帮助其他处于我这个阶段的人

<?php require "displaylist.php" ?

以下是一个应该让您开始学习的示例


<?php

$dbh = new PDO('mysql:host=localhost;dbname=mysql', 'username', 'password');
$stmt = $dbh->prepare('insert into orders (isbn, price) values (?, ?)');

if (isset($_SESSION['list']))
{
  foreach ($_SESSION['list'] as $item)
  {
    $stmt->execute(array($item['bookisbn'], $item['bookprice']));
  }
}
?>



不确定您想做什么，但我假设您想将存储在$\u会话['list']中的图书值插入mysql中的'orders'表中。以下是我对它的看法（假设“username”存储在某个会话变量中）：


那么到底是什么不起作用呢？您的displaylist.php文件中是否显示了任何内容？所以问题是，如何将
$\u SESSION['list']
中的数据获取到我的数据库中？@SenorPuerco不抱歉，displaylist.php工作正常，将所有这些项目放入数据库是最重要的struggle@AndrewR是的，你的权利！对不起，我没有说清楚！我将编辑，因此我们需要有关数据库设置的详细信息。您使用的是什么类型的数据库，您的表是什么样子的，等等。如果使用
mysql\uu
函数，请确保在将输入发送到数据库之前对其进行了清理。
