PHP会话没有传递到不同的页面（基本）

Question

我想通过一个变量从（register.php）到（submit.php），最后到（yes.php） - 请注意，我已经包括'session_start （）;”在每个页面中作为主要PHP页面上的“包含”。

register.php - 1

<div id = "content"> 
<form action="submit.php" method="post"> 
     <ul> 
      <li> 
       Username*:<br> 
       <input type="text" name="username"> 
      </li> 
      <br> 
      <li> 
       Email Address*:<br> 
       <input type="text" name="email"> 
      </li> 
      <br> 
      <li> 
       Telephone Number*:<br> 
       <input type="text" name="telephone"> 
      </li> 
      <br> 
      <li> 
       Telephone Again*: <br> 
       <input type="text" name="telephoneagain"> 
       <br> 
       </li> 
      <li> 
       <input type="submit" name="submit"> 

      </li> 
     </ul> 
    </form> 
</header> 

这是一个非常基本的登记表。 然后它被发送到

submit.php - 2

<?php 
<div id = "content"> 
<div id = "feature"> 
Your username is: <?php echo $_POST['username']; ?> <br> 
Your email address is: <?php echo $_POST['email']; ?> <br> 
Your telephone number is: <?php echo $_POST['telephone']; ?> <br> 
Just to confirm your telephone number: <?php echo $_POST['telephoneagain']; ?> 
<br> 
<br> 
</div> 
<div id = "validation"> 
Is this correct? <br> 
<li> <a href="yes.php"> Yes </a> </li> 
<li> <a href="register.php"> No </a> </li> 
<?php 
$_SESSION['username'] = $username; 
$_SESSION['email'] = $email; 
$_SESSION['telephone'] = $telephone; 
$_SESSION['telephoneagain'] = $telephoneagain; 
?> 
</div> 
</header> 

同样相当基础，忽视缺乏验证。所以在这里，我可以通过register.php输入用户名。然后，我点击“是”表示信息是正确的。

yes.php - 3

<?php 
$_POST['username']; 
?> 
<?php 
if(isset($_SESSION['username'])) 
    echo $_SESSION['username']; 
?> 
<?php 
$sql = "INSERT INTO users (username, email, telephone, telephoneagain) 
VALUES ('$username', '$email', '$telephone', '$telephoneagain')"; 
?> 

这里的问题是，变量没有从以前的页面传递，因此该页面无法找到他们。

人都在问我有没有在session_start（）的最后一页上，这里是完整的代码

这是yes.php - 3

<?php 
    include 'includes/yes/yeshead.php'; 
      include 'includes/yes/yesheader.php'; 
      include 'includes/yes/yescontent.php'; 
      include 'includes/yes/yesnav.php'; 
      include 'includes/yes/yesfooter.php'; 
    include 'core/init.php'; ?> 

的init.php包含在session_start（ ）;

<?php 
session_start(); 
error_reporting(-1); 

require 'core/database/connect.php'; 
require 'core/users.php'; 

$current_file = explode('/', $_SERVER['SCRIPT_NAME']); 
$current_file = end($current_file); 
$errors = array(); 
?>

亚历克斯帮助我解决了这个问题。我会给他回答点，但他发表评论，所以这将足够

Answer 2

直升机，尝试在submit.php：

$_SESSION['username'] = $_POST['username']; 
$_SESSION['email'] = $_POST['email']; 
$_SESSION['telephone'] = $_POST['telephone']; 
$_SESSION['telephoneagain'] =$_POST['telephoneagain']; 

和yes.php：

$username = $_POST['username']; 
$email = $_POST['email']; 
$telephone = $_POST['telephone']; 
$telephoneagain =$_POST['telephoneagain']; 

Answer 3

前人有关会议的代码，使用session_start();。

您正在使用与会话相关的文件，之后包含一个包含session_start();的文件。首先包含包含session_start();的文件。

在yes.php所以用这个：

<?php 
    include 'core/init.php'; 
    include 'includes/yes/yeshead.php'; 
      include 'includes/yes/yesheader.php'; 
      include 'includes/yes/yescontent.php'; 
      include 'includes/yes/yesnav.php'; 
      include 'includes/yes/yesfooter.php'; 
    ?> 

因此，请确保您在使用会话的每个代码添加session_start();，否则将无法正常工作。
