Registration and Login Form in PHP Using OOP

This article will help you to create object oriented user registration and login forms. Use the following procedure.

Step 1

Create a database using the following query.

Create database oopregister.

Step 2

Create a table using the following query:

CREATE TABLE IF NOT EXISTS `users` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`trn_date` datetime NOT NULL,
`name` varchar(50) NOT NULL,
`username` varchar(50) NOT NULL,
`email` varchar(50) NOT NULL,
`password` varchar(50) NOT NULL,
PRIMARY KEY (`id`)
);

Step 3

Create a class file named class.php, a database connection is also included in this file (don’t forget to change your database username and password):

<? php
define('HOST', 'localhost');
define('USER', 'root');
define('PASS', '');
define('DB', 'oopregister');
class DB
{
function __construct() {
$con = mysql_connect(HOST, USER, PASS) or die('Connection Error! '.mysql_error());
mysql_select_db(DB, $con) or die('DB Connection Error: ->'.mysql_error());
}
}
class User
{
public
function __construct() {
$db = new DB;
}
public
function register($trn_date, $name, $username, $email, $pass) {
$pass = md5($pass);
$checkuser = mysql_query("Select id from users where email='$email'");
$result = mysql_num_rows($checkuser);
if ($result == 0) {
$register = mysql_query("Insert into users (trn_date, name, username, email, password) values ('$trn_date','$name','$username','$email','$pass')") or die(mysql_error());
return $register;
} else {
return false;
}
}
public
function login($email, $pass) {
$pass = md5($pass);
$check = mysql_query("Select * from users where email='$email' and password='$pass'");
$data = mysql_fetch_array($check);
$result = mysql_num_rows($check);
if ($result == 1) {
$_SESSION['login'] = true;
$_SESSION['id'] = $data['id'];
return true;
} else {
return false;
}
}
public
function fullname($id) {
$result = mysql_query("Select * from users where id='$id'");
$row = mysql_fetch_array($result);
echo $row['name'];
}
public
function session() {
if (isset($_SESSION['login'])) {
return $_SESSION['login'];
}
}
public
function logout() {
$_SESSION['login'] = false;
session_destroy();
}
}
?>

Step 4

Create a register file named register.php as in the following:

<?php
include_once 'class.php';
$user = new User();
if ($_SERVER["REQUEST_METHOD"] == "POST"){
$trn_date = date("Y-m-d H:i:s");
$register = $user->register($trn_date,$_REQUEST['name'],$_REQUEST['username'],$_REQUEST['email'],$_REQUEST['password']);
if($register){
echo "Registration Successful!";
}
else
{
echo "Entered email already exist!";
}
}
?>
<html>
<head>
<title>Registration</title>
<link rel="stylesheet" href="style.css" />
</head>
<body>
<div class="form">
<h1>Registration</h1>
<form action="" method="post">
<input type="text" name="name" placeholder="Please Enter Name" required />
<br />
<input type="text" name="username" placeholder="Please Enter Userame" required />
<br />
<input type="text" name="email" placeholder="Please Enter Email" required />
<br />
<input type="password" name="password" placeholder="Please Enter Password" required />
<br />
<input type="submit" name="submit" value="Register" />
</form>
<p>Alredy Registered?<a href="login.php"> Login Here</a></p>
</div>
</body>
</html>

Step 5

Create a login file named login.php as in the following:

<?php
session_start();
include_once 'class.php';
$user = new User();
if ($user->session())
{
header("location:index.php");
}
$user = new User();
if ($_SERVER["REQUEST_METHOD"] == "POST"){
$login = $user->login($_REQUEST['email'],$_REQUEST['password']);
if($login){
header("location:index.php");
}
else
{
echo "Login Failed!";
}
}
?>
<html>
<head>
<title>Log In</title>
<link rel="stylesheet" href="style.css" />
</head>
<body>
<div class="form">
<h1>Log In</h1>
<form action="" method="post">
<input type="text" name="email" placeholder="Please Enter Email" required />
<br />
<input type="password" name="password" placeholder="Please Enter Password" required />
<br />
<input type="submit" name="submit" value="Login" />
</form>
<p>Not registered yet?<a href="register.php"> Register Here</a></p>
</div>
</body>
</html>

Step 6

Create an index file named index.php as in the following:

<?php
session_start();
include_once 'class.php';
$user = new User;
$id = $_SESSION['id'];
if (!$user->session()){
header("location:login.php");
}
if (isset($_REQUEST['q'])){
$user->logout();
header("location:login.php");
}
?>
<html>
<head>
<title>Dashboard</title>
<link rel="stylesheet" href="style.css" />
</head>
<body>
<div class="form">
<h1>Welcome <?php $user->fullname($id);?></h1>
<p align="right"><a href="?q=logout">LOGOUT</a></p>
</div>
</body>
</html>

Step 7

Create a style file named style.css as in the following:

body {
font - family: Arial, Sans - Serif;
}
a {
color: #78b941; text-decoration:none;}
a:hover {text-decoration:underline;}
.form {width: 300px; margin: 0 auto;}
input[type= 'text'], input[type = 'password'] {
width: 200 px;border - radius: 2 px;border: 1 px solid# CCC;padding: 10 px;color: #333; font-size: 14px; margin-top: 10px;}
input[type= 'submit'] {
padding: 10 px 25 px 8 px;color: #fff;background - color: #78b941; text-shadow: rgba(0,0,0,0.24) 0 1px 0; font-size: 16px; box-shadow: rgba(255,255,255,0.24) 0 2px 0 0 inset,# fff 0 1 px 0 0;border: 1 px solid #6faf38; border-radius: 2px; margin-top: 10px; cursor:pointer;}
input[type= 'submit']: hover {
background - color: #80c248;}

Step 8

After creating all the preceding files and running the program, the following will be the output screens of the registration and login forms.

Registration Screen.
Login Screen.
Dashboard Screen.
