我无法以学生身份登录
问题描述：
我面临的问题是当我以管理员身份登录时，该网站将直接进入管理主页。当我尝试以学生身份登录但没有任何反应。请帮我纠正错误。我无法以学生身份登录
这里是管理/ function.php
function login_user(){
global $con;
if(isset($_POST['submit'])){
//row dari database
//get from
$email = $_POST['email'];
$email_query=query("SELECT * FROM learn_users WHERE user_email='{$email}'");//sql language
if(mysqli_num_rows($email_query)==0){
//mysqli_num_rows akan kira berapa row dalam table itu
$_SESSION['email_not_valid']=$email;//sebelum redirect tu tambah nih blh masukkan
redirect("index.php");
}else{
$password = escape_string($_POST['password']);
$query = query ("SELECT * FROM learn_users WHERE user_email = '{$email}' AND user_password = '{$password}'");
confirm($query);
while($row = fetch_array($query)){
$db_user_email = $row['user_email'];
$db_user_password = $row['user_password'];
$db_user_role = $row['user_role'];
$db_username=$row['username'];
}
//set the user role, here is user role admin function, klaw user enter punya detail same as database will send the detail to $_session for hold the detail
if($email == $db_user_email && $password == $db_user_password && $db_user_role == "admin"){
$_SESSION['user_email'] = $db_user_email;
$_SESSION['user_role'] = $db_user_role;
$_SESSION['username']=$db_username;
//Go to the right page if password and email is correct and user role is admin
redirect("../admin/index.php");
}
if($email == $db_user_email && $password == $db_user_passwor && $db_user_role == "student"){
$_SESSION['user_email'] = $db_user_email;
$_SESSION['user_role'] = $db_user_role;
$_SESSION['username'] = $db_username;
redirect("../student/index.php");
}elseif($$email !== $db_username && $password !== $db_user_password){
redirect("index.php");
}else{
//Go to login page if two IF above not satisfied
redirect("index.php");
}
}
}
}
function admin_session(){
if(!isset($_SESSION['user_email']) && $_SESSION['user_role']!=='admin'){//session hanya boleh pegang satu account sahaja, untuk pakai remember me (keguaan)}
//isset mesti ada data
}else{
}
}
function student_session(){
if(isset($_SESSION['user_email']) && $_SESSION['user_role']=='student'){
//stay in student page
}else{
redirect("../login/index.php");
}
}
function student_logout(){
unset($_SESSION['user_email']);
unset($_SESSION['user_role']);
unset($_SESSION['username']);
redirect("../login/index.php");
}
function admin_logout(){
unset($_SESSION['user_email']);
unset($_SESSION['user_role']);
unset($_SESSION['username']);
//unset buang data
//Delete all session variables, xkan putar balik
//session_destroy();
//Jump to login page
redirect("../login/index.php");
}
function email_check(){//kalau user berjaya ditambah pakai function tersebut
if(empty($_SESSION['email_not_valid'])){
//if session is empty, then nt display any data.
}else{
//if session is not empty, then display message
?>
<div class ="alert alert-danger alert-dismissible" role="alert">

<strong>Strong;</strong><b><?php echo $_SESSION['email_not_valid']?></b>is not registered into this system.

这里的编码是编码的login.php：
<?php require MODEL_ROOT . '/admin/functions.php'; ?>
<div class="container">
<div class="row">
<div class="col-md-4 col-md-offset-4">
<div class="login-panel panel panel-default">
<div class="panel-heading">
<h3 class="panel-title">Please Sign In</h3>
</div>
<div class="panel-body">
<?php
email_check();//for email checking purposed
?>
<form role="form" action="" method="post">
<?php login_user() ?>
<fieldset>
<div class="form-group">
<!--for checking the user have enter email format to this column, if user enter wrong format, it will have error-->
<input class="form-control" placeholder="E-mail" name="email" type="email" autofocus>
</div>
<div class="form-group">
<input class="form-control" placeholder="Password" name="password" type="password" value="">
</div>
<div class="checkbox">
<label>
<input name="remember" type="checkbox" value="Remember Me">Remember Me
</label>
</div>
<!-- Change this to a button or input when using this as a form -->
<input type="submit" name="submit" class="btn btn-lg btn-success btn-block" value ="Login">
<!--<a href="index.html" class="btn btn-lg btn-success btn-block">Login</a>-->
</fieldset>
</form>
</div>
</div>
</div>
</div>
</div>
这里是我的student.php编码：
<?php require MODEL_ROOT . '/admin/functions.php';?>
<?php require VIEW_ROOT . '/templates-student/header.php';
student_session();
?>
<div id="wrapper">
<?php require VIEW_ROOT.'/templates-student/navigation.php';?>
<!-- Page Content -->
<div id="page-wrapper">
<div class="container-fluid">
<div class="row">
<div class="col-lg-12">
<h1 class="page-header">Blank</h1>
<?php
if($pages_url=="add_subject"){
require VIEW_ROOT . '/templates-admin/form-admin/form_add_subject.php';
}elseif($pages_url == "no page"){
echo "No page displayed";
}elseif($pages_url == "logout"){
admin_logout();//logout function
}elseif($pages_url=="manage_subject"){
manage_subject();
delete_subject();
}elseif($pages_url=="edit_subject"){
require VIEW_ROOT . '/templates-admin/form-admin/form_edit_subject.php';
}
else{
}
?>
</div>
<!-- /.col-lg-12 -->
</div>
<!-- /.row -->
</div>
<!-- /.container-fluid -->
</div>
<!-- /#page-wrapper -->
</div>
<!-- /#wrapper -->

如果这是逐字发布的，那么你的代码中应该有一个错字$ db_user_password：
if($email == $db_user_email && $password == $db_user_passwor && $db_user_role == "student"){
要在未来尝试捕获这样的错误，您可能需要尝试使用PHP严格错误报告模式。在脚本的头部，加入这一行：
error_reporting(E_STRICT);
这样，当你使用一个未声明的变量，which'll帮助你赶上错别字在您的编码程序应该抛出通知。

在部分登录错误代码
if($email == $db_user_email && $password == $db_user_passwor && $db_user_role == "student"){
$_SESSION['user_email'] = $db_user_email;
$_SESSION['user_role'] = $db_user_role;
$_SESSION['username'] = $db_username;
redirect("../student/index.php");
}
感谢你帮我解决问题。它运行良好 –
