PHP多步注册过程
[英]PHP multi-step registration process
问题描述
I am working on a registration system which comprises of 3 total steps. 
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 user is not found, user is directed to Step 2 . 如果未找到用户，则将用户转至步骤2 。
If status = no password created, the user is directed to Step 3 . 如果status =未创建密码，则将用户转至步骤3 。
If status = complete but not verified / registered and verified, Display error message. 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.
The page stores user inputs 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.
I have managed to figure out and complete the coding for the first 2 steps, by displaying a new form when the previous form has been submitted. 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。
Problem: However, I have just realised that I am unable to retrieve data from the previous form (ie: at step 3 I am unable to retrieve the Username from Step 1). 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）。 I have tried using the 'header('location: ?user=$uname');' 我试过使用'header（'location：？user = $ uname'）;' approach however this doest work because the URL gets reset when I submit the new form and I lose the username again. 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。 How do I create a proper multi-step form using ONLY PHP and how do I store the input values so I could use them at the last step. 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。 Below is my code: 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. PS。 I have looked into creating a session which gets destroyed when the user navigates away from the page Destroy PHP session on page leaving . 我已经研究过创建一个会话，当用户导航离开页面时， 会在页面离开时销毁PHP会话 。 However I find that it's not very user friendly as it doesn't work properly if the user has multiple tabs open. 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。 I understand that I need to implement a javascript function to make it work properly. 我知道我需要实现一个javascript函数才能使它正常工作。 I do not know how to code in javascript and would really appreciate your assistance on making a better multi-step registration process. 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。

As mentioned above, store the POST data from each step in the session variable. 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;
You can then use something like currentStep in the session to determine where they last were. 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'];
And compare to what data you need available, or just use it directly from the array. 并与您需要的数据进行比较，或者直接从数组中使用它。

I opted to follow the 'hidden variable' method where I store the values form the previous form in hidden inputs of the current form. 我选择遵循'隐藏变量'方法，我将前一个表单中的值存储在当前表单的隐藏输入中。 Thus enabling me to pass the values on to the next form. 从而使我能够将值传递给下一个表单。 A sort of snowball effect, if you will. 如果你愿意的话，有一种雪球效应。 Below is an example: 以下是一个例子：
Form 1
<form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>"> <div class="form-group"> <label for="Uname">Username: </label><br> <input type="text" name="uname" class="form-control" id="Uname" required> </div> <div class="form-group"> <label for="repeat_Uname">Repeat Username: </label><br> <input type="text" name="r_uname" class="form-control" id="repeat_Uname" required> </div> <input type="submit" name="username_chck" class="btn btn-default" value ="Next"> </form>
Form 2
<form method="post" action="<?php echo htmlspecialchars($_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=\"$username\"";}?>>
<input type="submit" name="user_info" class="btn btn-default" value ="Next">
Explanation
Below is a skeleton of my code which should help you understand how I have displayed the forms
if(empty($_POST['form1'])=== false){
$username = mysqli_real_escape_string($con, $_POST['username']);
// display form 2
}elseif(empty($_POST['form2'])=== false){
//display form 3
}
Note the hidden input type before the submit button in the second form . 请注意第二种形式的提交按钮之前的隐藏输入类型 。
While I have opted to include the if statements within the tags for the sake of this example, you could alternatively choose to process the forms at the top of your page (before the tag).
