我正在研究一个包含3个步骤的注册系统.
Step 1 – user enters a username, system searches the database for the
username. IF the username is found, it checks the account status (ie:
no password created, complete but not verified, registered and
verified).
如果未找到用户,则将用户转至步骤2.
如果status =未创建密码,则将用户转至步骤3.
如果status = complete但未验证/注册和验证,则显示错误消息.
Step 2 – user enters personal details.
该页面存储用户输入
Step 3 – user creates a password, the system connects to the database and INSERTs user info to the user table. A success message is
displayed.
通过在提交上一个表单时显示新表单,我设法找出并完成前两个步骤的编码.
问题：但是,我刚刚意识到我无法从上一个表单中检索数据(即：在步骤3中,我无法从步骤1中检索用户名).我试过使用’header(‘location：？user = $uname’);’然而,这种方法很有效,因为当我提交新表单时,URL会被重置,我又会丢失用户名.如何使用ONLY PHP创建正确的多步骤表单,如何存储输入值,以便在最后一步使用它们.以下是我的代码：
<?php
include 'includes/session_info.php';
if(isset($_SESSION['user_id'])){
header('Location: index.php');
}
$errors = array();
if(empty($_POST['user_info']) === false){
require ('core/dbcon.php');
$usr_email = mysqli_real_escape_string($con, $_POST['email']);
$usr_joined = mysqli_real_escape_string($con, $_POST['joined']);
$usr_recruited = mysqli_real_escape_string($con, $_POST['recruited']);
if($usr_email){
//direct user to password form
}else{
$errors[] = 'Please complete all fields marked with a Red Asterisk.';
}
$form2 = $usr_email.'<br>'.$usr_joined.'<br>'.$usr_recruited;
}
if(empty($_POST['username_chck']) === false){
require ('core/dbcon.php');
$username = mysqli_real_escape_string($con, $_POST['uname']);
$rpt_uname = mysqli_real_escape_string($con, $_POST['r_uname']);
if($username && $rpt_uname){
if($username == $rpt_uname){
$query = mysqli_query($con, "SELECT status FROM users WHERE username = '$username'") or die(mysqli_error($con));
// Display registration form if Username is not found.
if(mysqli_num_rows($query) == 0){
$form1;
}
// Actions performed If username entered already exists in the database.
elseif(mysqli_num_rows($query) == 1){
$status = mysqli_fetch_assoc($query);
if($status['status'] == 0){
$errors[] = '<b>'.$username.'</b> is already registered and awaiting to be verified by our admins. Feel free to contact an Admin via the website or in-game to get verified.';
}elseif($status['status'] == 1){
//header("Location:?create_pwd&user=$username");
}elseif($status['status'] > 1){
$errors[] = '<b>'.$username.'</b> is already registered and verified by our Admins. Please log in to access you account.
If you have forgotten your password you can rest your password <a class="navbar-link error_link" id="intext-link" href="login.php?fp"><b>here</b></a>.';
}
}elseif(mysqli_num_rows($query) > 1){
$errors[] = 'An error has occurred. Looks like a there is more than one member with that username. Please contact the Administrator for assistance.';
}
}else{
$errors[] = 'Please ensure that the username entered in both fields match.';
}
}else{
$errors[] = 'Please complete all required fields.';
}
}

PS.我已经研究过创建一个会在用户导航离开页面Destroy PHP session on page leaving时被销毁的会话.但是我发现它不是非常用户友好,因为如果用户打开了多个标签,它就无法正常工作.我知道我需要实现一个javascript函数才能使它正常工作.我不知道如何使用javascript进行编码,非常感谢您在制定更好的多步注册流程方面提供的帮助.
最佳答案 如上所述,存储会话变量中每个步骤的POST数据.
// Step 1 submit
$_SESSION['steps'][1] = $_POST;
// Step 2 submit
$_SESSION['steps'][2] = $_POST;
// Step 3 submit
$_SESSION['steps'][3] = $_POST;
然后,您可以在会话中使用类似currentStep的内容来确定它们的最后位置.
$currentStep = $_POST['step'];
并与您需要的数据进行比较,或者直接从数组中使用它.
