我正在研究一个包含3个步骤的注册系统。
第1步 - 用户输入用户名，系统在数据库中搜索 用户名。如果找到用户名，它会检查帐户状态（即： 没有创建密码，完整但没有验证，注册和 验证）。
如果找不到用户，则会将用户定向到步骤2 。
如果status =未创建密码，则会将用户定向到步骤3 。
如果状态=已完成但未经过验证/注册和验证，则显示错误消息。
第2步 - 用户输入个人详细信息。
页面存储用户输入
步骤3 - 用户创建密码，系统连接到数据库并将用户信息INSERT到用户表。一个成功的消息是 显示。
通过在提交上一个表单时显示新表单，我已经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）。我尝试使用＆＃39;标题（＆＃39;位置：？user = $ uname＆＃39;）;＆＃39;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.';
}
}

聚苯乙烯。我已经研究过创建一个会话，当用户离开页面Destroy PHP session on page leaving时会被破坏。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编写代码，非常感谢您协助我们制定更好的多步注册流程。
答案 0 :(得分：2)
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持续时间。
$currentStep = $_POST['step'];
与您需要的数据进行比较，或者直接从数组中使用它。

我选择关注隐藏变量＆＃39;我将前一个表单中的值存储在当前表单的隐藏输入中的方法。从而使我能够将值传递给下一个表单。如果你愿意的话，有一种雪球效应。以下是一个例子：
表单1
<form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>">
<div class="form-group">
<label for="Uname">Username: </label><br>
<input type="text" name="uname" class="form-control" id="Uname" required>
</div>
<div class="form-group">
<label for="repeat_Uname">Repeat Username: </label><br>
<input type="text" name="r_uname" class="form-control" id="repeat_Uname" required>
</div>
<input type="submit" name="username_chck" class="btn btn-default" value ="Next">
</form>
表格2
<form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>">
<div class="form-group">
<label for="Email">Email: </label>
<input type="email" name="email" class="form-control" id="Email" required <?php if (isset($_POST['email'])=== true){echo 'value="', strip_tags($_POST['email']),'"';}?>>
</div>
<input type="hidden" name="username" <?php if (isset($_POST['username'])=== true){echo 'value="', strip_tags($_POST['username']),'"';}else{echo "value=\"$username\"";}?>>
<input type="submit" name="user_info" class="btn btn-default" value ="Next">
<强>解释
下面是我的代码的框架，可以帮助您了解我如何显示表单
if(empty($_POST['form1'])=== false){
$username = mysqli_real_escape_string($con, $_POST['username']);
// display form 2
}elseif(empty($_POST['form2'])=== false){
//display form 3
}
请注意第二种表单中提交按钮之前的隐藏输入类型。
虽然为了这个例子我选择在标签中包含if语句，但您也可以选择处理页面顶部的表单（标签之前）。
