CARA LOGIN MENGGUNAKAN 3 TABLE Di PHP

Mohon Bantuannya Suhu, Bagaimana Caranya agar bisa login menggunakan 3 table yang terhubung

contoh 1 : Berhasil Login Menggunakan 2 Table

if($_SESSION['admin'] || $_SESSION['SISWA'] || $_SESSION['GURU']){

$ambil = $koneksi->query("SELECT * FROM login, siswa WHERE login.username='$username' AND login.password='$password' AND login.kode_login='$kode_login' and siswa.status='aktif' and siswa.kode_login='$kode_login' ");

Contoh 2 : Gagal Login Menggukan 3 Table

if($_SESSION['admin'] || $_SESSION['SISWA'] || $_SESSION['GURU']){

$ambil = $koneksi->query("SELECT * FROM login, siswa, guru WHERE login.username='$username' AND login.password='$password' AND login.kode_login='$kode_login' and siswa.status='aktif' and siswa.kode_login='$kode_login' and guru.kode_login='$kode_login' ");

Kira Kira Salahnya Dimana Yah Suhu untuk contoh 2; terima kasih.

    $ambil = $koneksi->query("SELECT * FROM login 
                              INNER JOIN siswa ON login.kode_login = siswa.kode_login AND siswa.status = 'aktif'
                              INNER JOIN guru ON login.kode_login = guru.kode_login
                              WHERE login.username = '$username' 
                              AND login.password = '$password' 
                              AND login.kode_login = '$kode_login'");
}

Saya menggunakan INNER JOIN untuk menggabungkan tabel siswa dan guru dengan login.

Kondisi WHERE digunakan untuk memeriksa username, password, dan kode_login.

Pastikan bahwa variabel $username, $password, dan $kode_login telah disanitasi sebelum digunakan dalam query untuk mencegah SQL Injection.

Masalah pertama

$_SESSION['admin'] = $data[kode_login];
$_SESSION['SISWA'] = $data[kode_login];
$_SESSION['GURU'] = $data[kode_login];

apakah ini benar penulisannya solusinya

 $data['kode_login'];

Masalah kedua data pada field ada atau tidak karena terdapat huruf besar dan huruf kecil tidak konsistem Solusi

$data['level']

Masalah Ketiga di select mysql tentukan apa yang yang mau dipilih jangan sampai sama nama fieldnya

"SELECT * FROM login 
INNER JOIN siswa ON login.kode_login = siswa.kode_login AND 
siswa.status = 'aktif'
INNER JOIN guru ON login.kode_login = guru.kode_login
WHERE login.username = '$username' AND login.password = '$password' 
AND login.kode_login = '$kode_login'"

solusinya

"SELECT login.kode_login, login.username, login.password, login.level 
FROM login 
INNER JOIN siswa ON login.kode_login = siswa.kode_login AND 
siswa.status = 'aktif'
INNER JOIN guru ON login.kode_login = guru.kode_login
WHERE login.username = '$username' AND login.password = '$password' 
AND login.kode_login = '$kode_login'"

tetap nggak bisa suhu,kira kira apa nya yah contoh script

<?php
  error_reporting(E_ALL ^ (E_NOTICE | E_WARNING));
  ob_start();
  session_start();
  include "koneksi/koneksi.php";

  if($_SESSION['ADMIN'] || $_SESSION['SISWA'] || $_SESSION['GURU']){
  
    }else{
