我正在使用PHP创建一个论坛,并尝试创建用户组

This is my "config.php" file:

    <?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');
    ?>

and this is my "delete_topic.php" file:

<?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)
{
?>

    echo '<h2>The topic you want to delete doesn\'t exist.</h2>';

    echo '<h2>You must be logged as an administrator to access this page: <a href="login.php">Login</a> - <a href="signup.php">Sign Up</a></h2>';
}
}
else
{
    echo '<h2>The ID of the topic you want to delete is not defined.</h2>';
}

?>

yet for some reason anyone in the $mod group cannot delete topics. This has been irking me for some time, as I need moderators to be able to delete topics, and edit posts, but they can't even delete the topic. Any suggestions? This is a really big project I'm working on and it is important to me that I can have mods AND admins as to differ between the two. [btw, the database info is filled out in MY config.php file]

    Your problem is here..

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

    What's happening is if the $admin conditional is not satisfied, you're finding yourself out of the block that allows deleting... I think you may want this instead

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

    Also please start using mysqli as mysql is deprecated.
