Question

我继承了一个小型办公室游泳池网站。最近我的主机升级了我的服务器，PHP脚本停止工作。我现在能够解决一些错误并抑制其他错误，但登录后不会保留$ user_id。登录后，我可以看到＆＃34;玩家＆＃34;链接。选择其中一个链接会显示页面，但无法访问用户。请求的任何新页面都表现得好像没有登录。我确定代码已经很老了。我只需要重新开始并完成赛季。我不知道该怎么做。希望可以阅读。

Answer 1

据我了解代码：登录后，user_id不会保存在Session中。此行$_session['userid']= $user_id;始终将用户ID设置为不存在的变量。

也许这有效：

<?  
session_start();

include "functions.php";
include "uiFunctions.php";

// log in/out sequence
if ($logout) $user_id = 0;
if ($login_step)
{
    $check = dbFetch("SELECT id FROM users WHERE user='".$userName."' AND 
pass=PASSWORD('".$userPass."') AND ((activated>0 AND 
banned=0) OR is_admin=1)");

    if ($check[0])
    {
        $user_id = $check[0];
        $page    = "";
        dbQuery("UPDATE users SET last_login=NOW() WHERE 
id='".$user_id."'");
        $_SESSION['userid']= $user_id; // Write in session
    }
}

// Read from session
$user_id = $_SESSION['userid'];
$user_info  = dbFetch("SELECT full_name, is_admin FROM users WHERE 
id='".$user_id."'");
$user_name  = $user_info[0];
$user_admin = $user_info[1];

$page_path = $_SERVER['PHP_SELF'];

PHP变量$ user_id代码停止工作
