php 会话变量被覆盖

Question

我制作了一个登录页面，该页面应该根据不同的组是否使用正确的详细信息登录来为他们分配会话['级别']。假设管理员登录，他获取 session['admin'] session['member'] 和 session['council'] ，这些都取决于他从数据库中的用户级别。 但是当我检查会话数组时我得到： id、用户名、管理员、管理员、管理员而不是 ID、用户名、管理员、理事会、成员。 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");
}

，检查每个用户凭据的函数是：

    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 . " | ";
    }

Answer 1

您将“admin”、“member”和“council”会话变量设置为相同的值：

$_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发生的情况：

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