SESSION参数不会转移到其他页面

我有一个登录页面,在登录时设置'id'的_SESSION参数。登录后,用户被重定向到index.php页面,此时会话参数仍然设置,我知道这是因为我可以用PHP打印它。但是,当导航到account.php页面时,参数会丢失,我不知道为什么。

此处询问的大多数其他问题都是因为没有使用session_start但我在account.php页面上使用了这个问题。

任何解决这个问题的帮助都会很感激。

account.php页面的代码如下:

<?php session_start(); ?>
<?php
$con=mysqli_connect("localhost","tkernick96","Tylerkernick1996","users");

if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}

$id = $_SESSSION['id'];

$query = mysqli_query($con,"SELECT * FROM users WHERE id = $id");

$row = mysqli_fetch_array($query,MYSQLI_ASSOC);
    $firstname = $row ['firstname'];
    $lastname = $row ['lastname'];
    $email = $row ['email'];
    $age = $row ['age'];
    $nationality = $row ['nationality'];
    $language1 = $row ['language1'];
    $language2 = $row ['language2'];
    $language3 = $row ['language3'];
    $language4 = $row ['language4'];
    $language5 = $row ['language5'];

$form = "<div id='header'>
           <img src='logo.png' id='logo'>
           <div id='headerdiv'>
            <table id='login'>
              <tr>

                  <h3 style='margin-top: 0px'><a href='signup.php'>Sign Up Now!</a></h3>
                </td>

2 个答案:

答案 0 :(得分:2)

它应该是$_SESSION而不是$_SESSSION

您应该看到具有正确错误报告级别的警告,例如

error_reporting(E_ALL);

答案 1 :(得分:0)

您使用的是IIS吗? 如果是,则应检查php.ini文件(在c:\ php或c:\ windows下),找到session.save_path参数,并确保指向存在的文件夹。 然后编辑该文件夹的权限并为IUSR用户授予读/写权限。

如果您正在使用Apache,您应该找到启动守护程序的用户(您可以在/etc/apache2/apache.conf中找到它),然后确保该用户在该文件夹中具有r / w权限那个php.ini session.save_path指向。

之后重启IIS或Apache。

希望它有所帮助。
