我试图挑战我的自我，但我坚持了(我尝试创建一个php表单，其中包含两个步骤的确认：

当用户填写表单并点击Submit时，它会检查所有条件(姓名、传递等)。如果一切正常，自动重定向用户。
重定向(到同一页)后，用户可以再次检查所有详细信息。如果他们确定，再次点击提交按钮，它重定向到最后一页。

我停留在第二phase...how重定向到最后一页？

我非常初学者，所以我很好奇，什么是可以做得更好或任何建议。

<?php
 // the php code 
session_start();


if ($_SERVER['REQUEST_METHOD'] == "POST") {

// setting up the variables

$title = $_POST['title'];
$fName = trim(filter_input(INPUT_POST,'fName', FILTER_SANITIZE_STRING));
$lName = trim(filter_input(INPUT_POST,'lName',FILTER_SANITIZE_STRING));
$age = intval($_POST['age']);


$_SESSION['title'] = $title;
$_SESSION['fName'] = $fName;
$_SESSION['lName'] = $lName;
$_SESSION['age'] = $age;



//checking for possible errors
if ( $fName == "" || strlen($fName) <= 2 ) {
    $errorMsg1 = "<span>Provide your First name!(minimum 3 characters)</span>";
    $status = false;

}
else if ( $lName == "" || strlen($lName) <= 2 ) {
    $errorMsg2 = "<span>Provide your Last name!(minimum 3 characters)</span>";
    $status = false;

}
else if ( $age < 18 ) {
    $errorMsg3 = "<span>You must be 18 or above!</span>";
    $status = false;

}

else {  $status = true; }

// redirecting to done page

if ($status) {
    header("Location:TEST ZONE.php?status=awaiting");
    }
  }

添加表单中的操作以重定向最终页面。

您已经有了会话中的所有值，所以您也可以在最后一页中访问它。

<?php

 // the php code 
session_start();


if ($_SERVER['REQUEST_METHOD'] == "POST") {

// setting up the variables

$title = $_POST['title'];
$fName = trim(filter_input(INPUT_POST,'fName', FILTER_SANITIZE_STRING));
$lName = trim(filter_input(INPUT_POST,'lName',FILTER_SANITIZE_STRING));
$age = intval($_POST['age']);


$_SESSION['title'] = $title;
$_SESSION['fName'] = $fName;
$_SESSION['lName'] = $lName;
$_SESSION['age'] = $age;



//checking for possible errors
if ( $fName == "" || strlen($fName) <= 2 ) {
    $errorMsg1 = "<span>Provide your First name!(minimum 3 characters)</span>";
    $status = false;

}
else if ( $lName == "" || strlen($lName) <= 2 ) {
    $errorMsg2 = "<span>Provide your Last name!(minimum 3 characters)</span>";
    $status = false;

}
else if ( $age < 18 ) {
    $errorMsg3 = "<span>You must be 18 or above!</span>";
    $status = false;
