Question

我有登录系统，当用户成功登录时会应用会话。这是你知道很久的事情，对吗？登录就像一个魅力，但之后不能应用任何会话。我试过var_dump它，print_r它，并且没有任何成功地回应它但没有任何错误。有人可以帮助兄弟吗？

代码

<?php 

require_once $_SERVER["DOCUMENT_ROOT"] . '/project-school/config/init.php';
session_start();

error_reporting(E_ALL); 
ini_set('display_errors', 'On'); 


if (isset($_POST['submit-admin-login']))
{
$username=db_escape($koneksi, $_POST['username']);
$password=db_escape($koneksi, md5($_POST['password']));

 if(empty($username) || empty($password)) 
    {
        $_SESSION['pesan'] = 'Username dan Password Wajib Diisi Dengan Benar';
        $_SESSION['alert'] = 'danger';
        header('location:../login.php');
    }
    else
    {
        $sqladmin= "SELECT * FROM admin WHERE username='$username' AND password='$password'";
        $queryadmin= mysqli_query($koneksi, $sqladmin) or die(mysqli_error($koneksi));          
        $resultadmin= mysqli_num_rows($queryadmin);

        $sqlpengajar= "SELECT * FROM pengajar WHERE username_login='$username' AND password_login='$password'";
        $querypengajar= mysqli_query($koneksi, $sqlpengajar) or die(mysqli_error($koneksi));
        $resultpengajar= mysqli_num_rows($querypengajar);

        if($resultadmin > 0)
        {
            while ($row = mysqli_fetch_array($queryadmin)) {
                $_SESSION['username_admin'] = $row['username'];
                $_SESSION['level']          = $row['level'];    
            }
            echo $_SESSION['username_admin'];
            header('Location: ../view/admin-dashboard.php');
        }
        elseif($resultpengajar > 0)
        {
            while ($row = mysqli_fetch_array($querypengajar)) {
            $_SESSION['nip']                = $row['nip'];
            $_SESSION['nama_lengkap']       = $row['nama_lengkap'];
            $_SESSION['level']              = $row['level'];
            $_SESSION['username_pengajar']  = $row['username_login'];
            $_SESSION['alamat']             = $row['alamat'];
            $_SESSION['tempat_lahir']       = $row['tempat_lahir'];
            $_SESSION['tgl_lahir']          = $row['tgl_lahir'];
            $_SESSION['jenis_kelamin']      = $row['jenis_kelamin'];
            $_SESSION['agama']              = $row['agama'];
            $_SESSION['foto']               = $row['foto'];
            }
            echo $_SESSION['username_pengajar'];
            header('Location: ../view/pengajar-dashboard.php');
        }
        else
        {
            $_SESSION['pesan'] = 'Username atau Password Anda Salah';
            $_SESSION['alert'] = 'danger';
            header('Location: ../login.php');
        }
    }       
}

会话在num_rows

之后开始

Answer 1

尝试在所需语句之前启动会话。像

<?php 
session_start();
require_once $_SERVER["DOCUMENT_ROOT"] . '/project-school/config/init.php';

每当你打算使用会话时，总是在第一次开始会话，否则php不会读取它。

您的sql注射风险很高。了解准备好的语句，以防止sql注入

会话无法正常工作而没有任何错
