PHP Login Page Example.

Are you looking for PHP login script, in this post I want to discuss how to create a simple PHP login with welcome page using MySQL database. This will explain you creating user tables, posting form values and storing and destroying the session values. If you are a PHP beginner take a quick look at this live demo with Username : test Password : test. This post has been updated with mysqli.


PHP Login Page Example



Download Script     Live Demo

New Tutorials: Ajax Login Page with Shake Effect and PHP Login System with PDO Connection.

Database
MySQL admin table columns id, username, passcode.
CREATE TABLE admin
(
id INT PRIMARY KEY AUTO_INCREMENT,
username VARCHAR(30) UNIQUE,
passcode VARCHAR(30)
);



Password Encryption PHP Login Script with Encryption.

Config.php
Database configuration file.
<?php
define('DB_SERVER', 'localhost');
define('DB_USERNAME', 'username');
define('DB_PASSWORD', 'password');
define('DB_DATABASE', 'database');
$db = mysqli_connect(DB_SERVER,DB_USERNAME,DB_PASSWORD,DB_DATABASE);
?>

New Tutorial: PHP Login Script with Encryption.

Login.php
Contains PHP and HTML code.
<?php
include("config.php");
session_start();
if($_SERVER["REQUEST_METHOD"] == "POST")
{
// username and password sent from Form
$myusername=mysqli_real_escape_string($db,$_POST['username']);
$mypassword=mysqli_real_escape_string($db,$_POST['password']);
$passwordSecure=md5($mypassword);
$sql="SELECT id FROM admin WHERE username='$myusername' and passcode='$passwordSecure'";
$result=mysqli_query($db,$sql);
$row=mysqli_fetch_array($result,MYSQLI_ASSOC);
$active=$row['active'];
$count=mysqli_num_rows($result);


// If result matched $myusername and $mypassword, table row must be 1 row
if($count==1)
{
session_register("myusername");
$_SESSION['login_user']=$myusername;

header("location: welcome.php");
}
else
{
$error="Your Login Name or Password is invalid";
}
}
?>
<form action="" method="post">
<label>UserName :</label>
<input type="text" name="username"/><br />
<label>Password :</label>
<input type="password" name="password"/><br/>
<input type="submit" value=" Submit "/><br />
</form>

lock.php
Session verification. If no session value page redirect to login.php
<?php
include('config.php');
session_start();
$user_check=$_SESSION['login_user'];

$ses_sql=mysqli_query($db,"select username from admin where username='$user_check' ");

$row=mysqli_fetch_array($ses_sql,MYSQLI_ASSOC);

$login_session=$row['username'];

if(!isset($login_session))
{
header("Location: login.php");
}
?>


welcome.php

<?php
include('lock.php');
?>
<body>
<h1>Welcome <?php echo $login_session; ?></h1>
</body>


logout.php

    A few hints:
    – Using addslashes() for escaping is bad practice
    – Storing passwords unencrypted is bad practice
    – session_register() is deprecated
    – A valid location headers require a full URL
    – lock.php makes no sense. The existence of a username and / or user ID in the session is sufficient, if the authentication was done properly. (Unless you want to check for every single request if a user account has been disabled or deleted.)

    why you place double check is it neccessary on that place . on welcome page include. instead of that placing if(!$_SESSION['login_user']):
    gogto login page

    @yu You need to create a database and use the username and password you used for that to connect to the database. Just using what is already there won't do anything as you found out (unless you did use the username root and password yes)

    ReplyDelete
  36. AnonymousJune 13, 2011 at 7:39 PM

    1. don't store passwords, use an md5 hash or better
    2. salt passwords before you create the hash
    3. store users, salt and password in different tables, where only a limited php page and limited mysql user can verify the login
    4. validate input always, unless its trusted
    5. use mysql procedures for ckecking user
    6. encrypt salt, note that this is ok but almost useless
    7. if your brave, and have a good memory, use 100% unique sql tables and fields..i.e.
    zu53Rs, xP4s5w0rds, y541ts
    zuSERs, xPAsSwOrds, ySAlts

    Not a bad little login example. Most examples don't use SESSIONS. Your example isn't perfect, but with a few tweaks it isn't bad now.

    1) You should encrypt passwords.

    2) On a few of the php files, the session_start() was not the FIRST line of code. Thus causing a error entry in the error_log. So ensure session_start(); is the VERY VERY VERY first line of code in each file that it is in!

    3) Also, another minor error creating an entry in error_log. It is because on when a user isn't logged in, the session variable is null/nothing/empty... And you don't check if it is empty, you just assume there is a value and perform a database query with an empty username.

    Lock.php:

    session_start();
    if(!isset($_SESSION['login_user'])){
    header("location:login.php");

    you can change this :

    change admin to database phpmyadmin you table,so will work.

    Thanks for this, helped me to understand sessions better.

    Anyone wanting to store the passwords in an MD5 can so so easily by firstly ensuring the passwords are MD5 in the database (store it in a VARCHAR) and then simply add $mypassword=md5($mypassword); under $mypassword=addslashes($_POST['password']);

    Easy
