セッション変数を取得する問題

Question

私のlogin.phpをmain.phpの私のホームページにリダイレクトしようとしています。ログインに失敗した場合はログインしたメッセージをエコーし​​ます。これは、スクリプトの速い部分を無視してまで私を演出します

場所：http://localhost/projects/ibill_v3/html/loginformfail.html#home

これも存在しません。これを修正する方法はありますか、あまりにも複雑にしていますか？どんな助けでも大歓迎です！

main.php（ホームページ）

<?php 
    session_start(); 
include "loginform.php"; 
if (isset($_SESSION['user_session']) and $_SESSION['user_session']!=""){ 
    echo 'working'; 
} 
else { 
    echo 'not working'; 
} 
?> 

loginform.php

<?php 
$con=mysqli_connect('localhost','root','cornwall','ibill'); 
// This code creates a connection to the MySQL database in PHPMyAdmin named 'ibill': 

$username=""; 
$password=""; 

if (isset ($_POST['username'])){ 
$username = mysqli_real_escape_string($con, $_POST['username']); 
} 
if (isset ($_POST['password'])){ 
$password = mysqli_real_escape_string($con, $_POST['password']); 
} 
//These are the different PHP variables that store my posted data. 

$login="SELECT * FROM users WHERE username='$username' AND password='$password'"; 
$result=mysqli_query($con, $login); 
$count=mysqli_num_rows($result); 
//This is the query that will be sent to the MySQL server. 
if($count==1) 
{ 
    $_SESSION["user_session"]=$username; 
    header('Location: http://localhost/projects/ibill_v3/html/main.php#home'); 
    exit(); 
} 
//This checks the 'user_details' database for correct user registration details and if successful, directs to home page. 
else { 
    header('Location: http://localhost/projects/ibill_v3/html/loginformfail.html'); 
    exit(); 
} 
//If login details are incorrect 

/** Error reporting */ 
error_reporting(E_ALL); 
ini_set('display_errors', 1); 
ini_set('display_startup_errors', 1); 
?>

ステップ1：login.phpにloginform.phpし提出する上でアクションを設定（アクション= "loginform.phpを"）

step2：loginform.phpでセッションを開始し、リダイレクトの場所をmain.phpに変更します

<?php 
 
session_start(); 
 
$con=mysqli_connect('localhost','root','cornwall','ibill'); 
 
// This code creates a connection to the MySQL database in PHPMyAdmin named 'ibill': 
 

 
$username=""; 
 
$password=""; 
 

 
if (isset ($_POST['username'])){ 
 
$username = mysqli_real_escape_string($con, $_POST['username']); 
 
} 
 
if (isset ($_POST['password'])){ 
 
$password = mysqli_real_escape_string($con, $_POST['password']); 
 
} 
 
//These are the different PHP variables that store my posted data. 
 

 
$login="SELECT * FROM users WHERE username='$username' AND password='$password'"; 
 
$result=mysqli_query($con, $login); 
 
$count=mysqli_num_rows($result); 
 
//This is the query that will be sent to the MySQL server. 
 
if($count==1) 
 
{ 
 
    $_SESSION["user_session"]=$username; 
 
    header('Location:main.php'); 
 
    exit(); 
 
} 
 
//This checks the 'user_details' database for correct user registration details and if successful, directs to home page. 
 
else { 
 
    header('Location: main.php'); 
 
    exit(); 
 
} 
 
//If login details are incorrect 
 

 
/** Error reporting */ 
 
error_reporting(E_ALL); 
 
ini_set('display_errors', 1); 
 
ini_set('display_startup_errors', 1); 
 
?>

ステップ3：main.php削除で "loginform.php" を含みます。

<?php 
 
    session_start(); 
 
if (isset($_SESSION['user_session']) and $_SESSION['user_session']!=""){ 
 
    echo 'working'; 
 
} 
 
else { 
 
    echo 'not working'; 
 
} 
 
?>
