如何在php中使用會話將文本框數據傳遞到下一頁

Question

我想將文本框數據傳遞到下一頁（demo2），我需要將所有數據一起保存在我的數據庫中我嘗試使用會話，我傳遞的值正在發送到下一頁，但我希望文本框數據被傳遞...

下面是我的代碼

演示1.php

<?php
session_start();
 if($_POST)
 {
        if($_POST['act'] == "add")
    {
        $firstname = $_POST['firstname'];
        $lastname = $_POST['lastname'];
        $nationality = $_POST['nationality'];   

        $conn = mysql_connect("localhost","root","");
        $db = mysql_select_db("reg",$conn);

    }
}

echo "Session variables are set.";

if(@$_GET)
{
      $_SESSION["firstname"] = "$firstname";
      $_SESSION["lastname"] = " $lastname"; 
      $_SESSION["nationality"] = "$nationality"; 
      echo $firstname;
      echo $lastname;
      echo $nationality;
}
 ?>
    <!DOCTYPE html>
<html lang="en">

<body>
    <form  method="POST">

            <?php if(isset($_GET['id'])) { ?>
            <input type="hidden" name="act" value="edit"/>
            <input type="hidden" name="id" value="<?php echo $id; ?>"/>

            <?php } else{ ?>
            <input type="hidden" name="act" value="add"/>
            <?php } ?>

                                                                                <label> FirstName</label>

                                                          $_SESSION["nationality"] = "Indian";  ?>

將錨標記代碼替換為：

<a href="demo2.php?firstname=<?php $_POST['firstname'] ?>&lastname=<?php $_POST['lastname'] ?>&nationality=<?php $_POST['nationality'] ?>"> <input type="button" id="next" name="next" value="next" ></a>

在 demo2.php 上：

$fname = $_GET['firstname'];
$lname = $_GET['lastname'];
$nationality = $_GET['nationality'];
