php/mysql-基于user_level重定向时出现的问题 [英] php / mysql - Issue when redirecting based on user_level

问题描述

我目前正在基于user_level构建一个控制面板.如果用户的权限为(0)，则除了索引页面外，他们无法访问其他任何内容，而级别(1)则可以访问所有内容.

I'm currently building a control panel based on user_level. If a user has level (0) they can't access anything besides the index page, level (1) can access everything.

我的问题是，使用我当前使用的代码...即使将user_level设置为0以上，它也只能将我重定向回索引页面.

My problem is, with the current code I am using... It only redirects me back to the index page, even if I set my user_level above 0.

代码:

<?php
$db_connection = new mysqli(DB_HOST, DB_USER, DB_PASS, DB_NAME);
require_once("config/db.php");

$page_rows = results_per_page;

if (!$db_connection->set_charset("utf8")) {
    $db_connection->errors[] = $db_connection->error;
}

if($_SESSION["user_level"] == 0)
                {
                header('Location: index.php');
                }
?>

如果我尝试使用以下代码......

and If I try using the following code....

<?php
$db_connection = new mysqli(DB_HOST, DB_USER, DB_PASS, DB_NAME);
require_once("config/db.php");

$page_rows = results_per_page;

if (!$db_connection->set_charset("utf8")) {
    $db_connection->errors[] = $db_connection->error;
}

if($_SESSION["user_level"] == 0) {
        header('Location: index.php');
    } else {
        header('Location: download.php');
?>

在download.php页面上显示 HTTP错误500 .

I get HTTP ERROR 500 on the download.php page.

感谢所有帮助. (对不起，"Noob"的错误，这是我的第一个更大的项目.)

All help is appreciated. (Sorry for any 'Noob' mistakes, This is my first bigger project).

推荐答案

您正在使用session，如:

if($_SESSION["user_level"] == 0)
{
    header('Location: index.php');
}

，但会话未在此处开始.在第一行开始会话，如:

but session is not started here. Start the session on first line like:

session_start();

只有在此之后，您才能访问会话变量.

only after that you can access the session variable.
