Question

我做了一个登录页面，根据他们是否使用正确的详细信息登录，应该为会话['级别'指定不同的组。说管理员登录他得到会话['admin']会话['成员']和会话['理事会']，这些都依赖于他在数据库中的用户级别。但当我检查会话数组时，我得到： id，username，admin，admin，admin而不是 id，username，admin，council，member。我用于查询的代码是

//normal user
$queryN= mysql_query("SELECT * From users where username='$username' and hashed_password ='$dash' AND
level='member' LIMIT 1");
//normal council member
 $queryC = mysql_query("SELECT * From users where username='$username' and hashed_password ='$dash' AND
level='council' LIMIT 1");
//normal admin
$queryA = mysql_query("SELECT * From users where username='$username' and hashed_password ='$dash' AND
level='admin' LIMIT 1");
//Check whether the query was successful or not      
//normal user
if(mysql_num_rows($queryN) == 1)
{session_regenerate_id();
$resultN = mysql_fetch_assoc($queryN);  
$_SESSION['user_id'] = $resultN['id'];
$_SESSION['username'] = $resultN['username'];       
$_SESSION['member'] = $resultN['level']; 
session_write_close();
redirect_to("../public/index.php");
}
//admin user
elseif(mysql_num_rows($queryA) == 1){
session_regenerate_id();
$resultA = mysql_fetch_assoc($queryA);   
$_SESSION['user_id'] = $resultA['id'];
$_SESSION['username'] = $resultA['username']; 
$_SESSION['admin'] = $resultA['level']; 
$_SESSION['member'] = $resultA['level'];
$_SESSION['council'] = $resultA['level']; 
session_write_close();
redirect_to("../public/staff.php");
}

//council user
elseif(mysql_num_rows($queryC) == 1){
session_regenerate_id();
$resultC = mysql_fetch_assoc($queryC);  
$_SESSION['user_id'] = $resultC['id'];
$_SESSION['username'] = $resultC['username'];  
$_SESSION['council'] = $resultC['level']; 
$_SESSION['member'] = $resultC['level'];
session_write_close();
redirect_to("../public/index.php");
}else{
//Login failed
redirect_to("../public/login.php");
}

以及检查每个用户凭据的功能是：

    session_start();
    $_SESSION['ERRMSG_ARR'] = array(); 
    function logged_in() {
        return isset($_SESSION['level']);
    }

    function confirm_logged_in() {
if(!isset ($_SESSION['member']) || (trim($_SESSION['member']) == '')) {
$_SESSION['ERRMSG_ARR'][] = 'You were not Authorised to view that page';
            redirect_to("login.php");
        }
    }
function confirm_login_council() {
if(!isset ($_SESSION['council']) || (trim($_SESSION['council']) == '')) {
        $_SESSION['ERRMSG_ARR'][] = 'Sorry but you were not Authorised to view that page';
        redirect_to("login.php");
        }
    }
function confirm_login_admin(){
if(!isset($_SESSION['admin']) || (trim($_SESSION['admin']) == '')) {
    $_SESSION['ERRMSG_ARR'][] = 'Unfortunately for you; You were not Authorised to view that page';
            redirect_to("login.php");
        }
    }

并检查我使用的会话数组值：

  foreach($_SESSION as $value){
        echo $value . " | ";
    }

您正在设置＆＃34; admin＆＃34;，＆＃34;会员＆＃34;和＆＃34;理事会＆＃34;会话变量为相同的值：

$_SESSION['admin'] = $resultA['level']; 
$_SESSION['member'] = $resultA['level'];
$_SESSION['council'] = $resultA['level'];

尝试使用密钥进行打印，以更清楚地了解正在进行的操作：

foreach($_SESSION as $key => $value){
  echo $key, ':', $value , ' | ';
}

会话变量被覆盖php
