我有两个PHP页面：index.php和thankyou.php。在index.php中，有一个表单。我正在使用Javascript和ajax验证表单，并将表单值插入到数据库中。在数据库查询后，我将此表单重定向到Thankyou.php。我想要的是将表单字段值传递给thankyou.php。请在下面找到完整的代码。 ：
在标头中运行的SQL查询： -
?php
error_reporting(0);
include_once('cc/connect.php');
if($_SERVER['REQUEST_METHOD'] === 'POST')
{
$str="insert into registration(fname,lname,email,mobile_number,code,designation,organization,comps,city,affid,date_time,status)values('".mysql_escape_string($_POST['txtfname'])."','".mysql_escape_string($_POST['txtlname'])."','".mysql_escape_string($_POST['txtemail'])."','".mysql_escape_string($_POST['txtmobilenumber'])."','".mysql_escape_string($_POST['txtcode'])."','".mysql_escape_string($_POST['desig'])."','".mysql_escape_string($_POST['org'])."','".mysql_escape_string($_POST['comps'])."','".mysql_escape_string($_POST['txtcity'])."','".mysql_escape_string($_POST['txtaff'])."',now(),0)";
$rslt=mysql_query($str);
if(!$rslt)
{
echo '<script type="text/javascript">
alert("We are experiencing some issues, please try later");
</script>
';
}

最简单的方法是使用PHP会话。这些将存储来自与用户的一次交互的数据，以便在另一次交互中检索。
在 connect.php 中，添加：
session_start();
在 index.php 中，在数据库中验证并保存信息后，保存要在$_SESSION数组中的页面之间传递的数据
$_SESSION['fname'] = $_POST['txtfname'];
....
在您完成所有字符串操作后（例如：应用mysql_escape_string之后）将事物保存到会话实际上更好。
现在，只要用户发出另一个请求，您就可以在同一个数组中找到数据。所以在 thankyou.php
$fname = $_SESSION['fname'];
...
这是一个基本的intro to sessions。
下一个注释超出了您的问题，但它是一个非常重要的一课：会话依赖于Cookie来识别用户再次访问时。这意味着精明的用户可以操纵此cookie并打破他的会话或尝试将自己呈现为其他人以绕过您的安全限制。一旦您对基础知识感到满意，请研究如何安全地使用会话！

这听起来像$_SESSION可能派上用场的典型案例。在这种情况下（因为你正在用AJAX做事），你可能想要在你的AJAX处理PHP文件中处理会话...（header.php？）这里的方法如下：
<?php
// FILE-NAME: header.php //<== THE AJAX PROCESSING SCRIPT
//FIRST CHECK IF SESSION EXIST BEFORE STARTING IT:
if (session_status() == PHP_SESSION_NONE || session_id() == '') {
session_start();
}
error_reporting(0);
include_once('cc/connect.php');
if($_SERVER['REQUEST_METHOD'] === 'POST') {
// JUST START SETTING UP THE SESSION DATA IF DATA WAS POSTED...
$_SESSION['fname'] = htmlspecialchars(trim($_POST['txtfname']));
$_SESSION['lname'] = htmlspecialchars(trim($_POST['txtlname']));
$_SESSION['email'] = htmlspecialchars(trim($_POST['txtemail']));
$_SESSION['mobile_number'] = htmlspecialchars(trim($_POST['txtmobilenumber']));
$_SESSION['code'] = htmlspecialchars(trim($_POST['txtcode']));
$_SESSION['designation'] = htmlspecialchars(trim($_POST['desig']));
$_SESSION['organization'] = htmlspecialchars(trim($_POST['org']));
$_SESSION['comps'] = htmlspecialchars(trim($_POST['comps']));
$_SESSION['city'] = htmlspecialchars(trim($_POST['txtcity']));
$_SESSION['affid'] = htmlspecialchars(trim($_POST['txtaff']));
$_SESSION['date_time'] = date("Y-m-d", time());
$_SESSION['status'] = "0";
$str="insert into registration(fname,lname,email,mobile_number,code,designation,organization,comps,city,affid,date_time,status)values('".mysql_escape_string($_POST['txtfname'])."','".mysql_escape_string($_POST['txtlname'])."','".mysql_escape_string($_POST['txtemail'])."','".mysql_escape_string($_POST['txtmobilenumber'])."','".mysql_escape_string($_POST['txtcode'])."','".mysql_escape_string($_POST['desig'])."','".mysql_escape_string($_POST['org'])."','".mysql_escape_string($_POST['comps'])."','".mysql_escape_string($_POST['txtcity'])."','".mysql_escape_string($_POST['txtaff'])."',now(),0)";
$rslt=mysql_query($str);
//... THE REST OF YOUR CODE...
}
然后，在thankyou.php内，你可以这样做：
<?php
// FILE-NAME: thankyou.php
//FIRST CHECK IF SESSION EXIST BEFORE STARTING IT:
if (session_status() == PHP_SESSION_NONE || session_id() == '') {
session_start();
}
// TO GET THE EMAIL, FIRST & LAST NAMES HERE, YOU CAN SIMPLE DO LIKE SO:
$email = isset( $_SESSION['email'] )? $_SESSION['email'] : "";
$firstName = isset( $_SESSION['fname'] )? $_SESSION['fname'] : "";
$lastName = isset( $_SESSION['lname'] )? $_SESSION['lname'] : "";
// ASSUMING YOU WANT TO THANK THE USER BY NAME:
// YOU MAY DO SOMETHING LIKE SO:
$thankYou = "<div class='thank-you'>" . PHP_EOL;
$thankYou .= "<p class='appreciation'>Thank you, " ;
$thankYou .= "<span class='user-name'>{$firstName} {$lastName}</span>";
$thankYou .= " for your E-Mail... bla...bla..</p>" .PHP_EOL;
$thankYou = "</div>" . PHP_EOL;
echo $thankYou;
