我是PHP和STACKOVERFLOW的新手，我有这个项目来创建一个简单的预订房间。 我已经让它在简单的PHP上做CRUD但现在我想创建数据表，以便我可以显示我的数据看起来更好。但我真的不知道如何使用这个数据表，我已经将数据库配置和表更改为我想要的那个，但它仍然返回空 这是我的代码片段，因此用户将输入日期并重定向到此页面，我还包括数据表的脚本
<?php
include ("connect.php");
session_start();
$datebook = $_POST["datepicker"];
$_SESSION['date']=$datebook;
$nim= $_SESSION['nim'];
echo('Selected Date=');
echo($datebook);
mysqli_close($connect);
?>

这个是针对serverSide.php的数据表引用的那个
