目前，我的代码有问题。我为过滤日期范围创建了一个系统。在进行数据过滤之前，它将显示所有数据，但是当我输入日期范围并单击按钮时，尽管我输入了正确的日期范围，但仍将显示“未找到已购买的物品”。下面是我的代码
index.php
<?php
require_once "configPDO.php";
$query = "SELECT * FROM booking ORDER BY Book_No DESC";
$sql = $conn->prepare($query);
$sql -> execute();
?>

我会要求您向我展示数据库的结构，以确定您是否遗漏了任何字段名称或匹配了错误的日期格式。如果您提供的话，我也许可以为您提供帮助。
