我正在使用PHP建立論壇,並試圖建立用戶組

[英]I'm using PHP to make a forum, and trying to make usergroups

這是我的“ config.php”文件:

    <?php
/******************************************************
------------------Required Configuration---------------
Please edit the following variables so the forum can
work correctly.
******************************************************/

//We log to the DataBase
mysql_connect('', '', '');
mysql_select_db('');

//Username of the Administrators
$admin='Hexagon';
$mod='test1';

/******************************************************
-----------------Optional Configuration----------------
******************************************************/

//Forum Home Page
$url_home = 'index.php';

//Design Name
$design = 'default';


/******************************************************
----------------------Initialization-------------------
******************************************************/
include('init.php');
    ?>

這是我的“ delete_topic.php”文件:

<?php
//This page let delete a topic
include('config.php');
if(isset($_GET['id']))
{
    $id = intval($_GET['id']);
if(isset($_SESSION['username']))
{
    $dn1 = mysql_fetch_array(mysql_query('select count(t.id) as nb1, t.title, t.parent, c.name from topics as t, categories as c where t.id="'.$id.'" and t.id2=1 and c.id=t.parent group by t.id'));
if($dn1['nb1']>0)
{
if($_SESSION['username']==$admin)
if($_SESSION['username']==$mod)
{
?>

但是由於某些原因,$ mod組中的任何人都無法刪除主題。 這讓我很討厭,因為我需要主持人刪除主題和編輯帖子,但他們甚至無法刪除主題。 有什么建議么? 這是我正在從事的一個非常大的項目,對我來說很重要的一點是,我可以擁有mods和admin,以使兩者之間有所不同。 [順便說一句,數據庫信息填寫在MY config.php文件中]

解決此問題的一種好方法是在用戶(或成員)表中創建一個字段,並將此字段稱為“ user_levels”,在其中設置
管理員為1
主持人為2
其他成員為3或為空或為0(隨心所欲)。
比您可以設置會話$_SESSION['user_levels']並始終按以下方式檢查該會話

if ($_SESSION['user_levels']==1 || $_SESSION['user_levels']==2) 
{ 
   // Grant him permission to delete the record 
} 
else 
{ 
   // tell him that he is not authorize to delete it 
}

您的問題在這里。

if($_SESSION['username']==$admin)
if($_SESSION['username']==$mod)
{

發生的情況是,如果不滿足$ admin條件,您將發現自己已超出允許刪除的范圍...我想您可能希望這樣做

if($_SESSION['username']==$mod || $_SESSION['username']==$admin)
{

另外,由於不建議使用mysql,請開始使用mysqli。
