javascript - 根据我数据库中的 id 将数据从 html 对象传递到另一个对象

Question

所以我有两个文件:index.php和details modal.php。在索引 .php 文件中，我设法创建一个动态对象，该对象显示存储在数据库中的产品的标题、价格和图像。那就是完美的。正如您在图像中看到的那样，每个产品都有一个按钮，上面写着 Detalles(详细信息)，该按钮是动态生成的。该按钮在页面顶部打开一个小窗口(称为detailsmodal.php)。我想根据我选择的产品显示其中的数据。我尝试从数据库调用数据，但它只能调用产品一的数据(这意味着如果我单击产品2，它仍然显示产品1的数据)我该如何解决这个问题？这是一些屏幕截图以及我的index.php 和detailsmodal.php 代码。

Answer 1

因为您给所有模态都提供了相同的 id，所以它将始终调用具有相同 id 的第一个模态。只需查看更新后的代码。

<?php
require_once'core/init.php';
include'includes/head.php';
?>
<!--Navegacion-->
<?php
include('includes/navigation.php');
?>
<!-- Cabecera-->
<?php
include('includes/headerfull.php');
?>
<!--left side bar-->
<?php
include('includes/leftbar.php');


?>
<?php
$sql =  "SELECT * FROM products WHERE featured = 1";
$featured= $db->query($sql);
?>
