Question

我正在尝试将变量从（register.php）传递到（submit.php），最后传递给（yes.php） - 请注意我已经包含了＆＃39; session_start（）;＆＃39;在每个页面中作为＆＃39;包含＆＃39;在主要的php页面上。

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注册表格。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>

再次相当基本，忽略缺乏验证。所以在这里，我可以回复一下在register.php上输入的用户名。然后我点击“是”＆＃39;表明信息是正确的。

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上一页传递，因此页面找不到它们。

人们问我最后一页是否有session_start（），这里是完整代码

这是针对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'; ?>

init.php包含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();
?>

非常善良的Alex帮助我解决了这个问题。我会给他答案，但他发表了评论，所以这就足够了

Answer 2

Helo，试试submit.php：

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

并在yes.php中：

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

Answer 3

在与会话相关的代码之前，请使用session_start();。

您包含与会话相关的文件，之后您包含一个包含session_start();的文件。首先包含session_start();包含的文件。

所以在yes.php中使用它：

 <?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，请确保在每个使用会话的代码中添加session_start();，否则它将无效。

PHP会话没有传递到不同的页面（基本）
