PHP Login and Registration Script with MySQL Example

On 9/07/2017

PHP Login and Registration Script: User Login/registration system is one of the key components of any membership driven websites and the ability to build them is a must have skill for any web developer. In this post, let us see how to create a complete login and registration system using php and mysql database.

This tutorial is fairly simple and easy to understand, but it covers as much as required to build advanced login/registration system - right from data validation to maintaining php sessions for authenticated access.

MySQL Database for Login/Registration Module

Before entering into the coding part, first let us build the database required for this example.

CREATE DATABASE `testdb`;
USE `testdb`;

CREATE TABLE IF NOT EXISTS `users` (
  `id` int(8) NOT NULL AUTO_INCREMENT,
  `name` varchar(30) NOT NULL,
  `email` varchar(60) NOT NULL,
  `password` varchar(40) NOT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `email` (`email`)
) ENGINE=MyISAM  DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;

Run this sql file in phpmyadmin interface and create the database and table.

PHP Script for Login and Registration System

To build the login/registration system we need to create the following files.

  • index.php - This is the home page of our application
  • register.php - It contains the user sign up form
  • login.php - It contains the login form
  • logout.php - This contains the user logout script
  • dbconnect.php - MySQL database connection script

System Flow for User Login Registration Module

These are the steps breakdown of the user registration/login module we are going to build.

  1. The Home page (index.php) contains links for login and sign up process in top navigation menu.
  2. For new users » click on sigup link » user redirected to registration form » fill up the form and submit » validate the form input » registration succeed » notify user and redirect to login page.
  3. For registered users » click on login link on index.php » user redirected to login page » user provide login credentials » authenticate user and redirect to index page.
  4. For signed in users » show user's name and logout link on navigation bar.
  5. User clicks on logout » delete user details from session variable and destroy session » redirect to Home page.

Note: This tutorial uses twitter bootstrap framework for css. I prefer to use this as it's readily available and you can easily integrate bootstrap with HTML. But if you prefer custom style sheet then you can simply attach one and replace all the class selectors used in the html tags with your own. However the program functionality remains the same and will not be disturbed.

Dbconnect.php

This is where we connect to the mysql database. Keeping database connectivity in a separate file is very handy. This way you can get access to database across multiple files by simply including the file once and access it anywhere.

<?php
//connect to mysql database
$con = mysqli_connect("localhost", "myusername", "mypassword", "testdb") or die("Error " . mysqli_error($con));
?>

Register.php

This php file contains the code for the user registration process. The access to this page will be restricted for signed in user. We do this by checking out the session variable.

<?php
session_start();

if(isset($_SESSION['usr_id'])) {
    header("Location: index.php");
}

include_once 'dbconnect.php';

//set validation error flag as false
$error = false;

//check if form is submitted
if (isset($_POST['signup'])) {
    $name = mysqli_real_escape_string($con, $_POST['name']);
    $email = mysqli_real_escape_string($con, $_POST['email']);
    $password = mysqli_real_escape_string($con, $_POST['password']);
    $cpassword = mysqli_real_escape_string($con, $_POST['cpassword']);
    
    //name can contain only alpha characters and space
    if (!preg_match("/^[a-zA-Z ]+$/",$name)) {
        $error = true;
        $name_error = "Name must contain only alphabets and space";
    }
    if(!filter_var($email,FILTER_VALIDATE_EMAIL)) {
        $error = true;
        $email_error = "Please Enter Valid Email ID";
    }
    if(strlen($password) < 6) {
        $error = true;
        $password_error = "Password must be minimum of 6 characters";
    }
    if($password != $cpassword) {
        $error = true;
        $cpassword_error = "Password and Confirm Password doesn't match";
    }
    if (!$error) {
        if(mysqli_query($con, "INSERT INTO users(name,email,password) VALUES('" . $name . "', '" . $email . "', '" . md5($password) . "')")) {
            $successmsg = "Successfully Registered! <a href='login.php'>Click here to Login</a>";
        } else {
            $errormsg = "Error in registering...Please try again later!";
        }
    }
}
?>

This is how the registration form looks like.

php-sign-up-script

Registration form requires user to fill up name, email id and password and confirm password fields. All the fields are mandatory and user will be asked to provide the data if it is left blank like this.

php-registration-form-validation

Once the user fills out the details and submits the form for sign up, we sanitize the received data to avoid sql injection and validate the form input. If validation fails the user will be shown with the appropriate error message below each form input like this.

php-registration-form-validation-error
php-registration-password-validation

If the validation succeeds the data will be stored in the database and user will be shown with the login link.

Login.php

This file contains the php code for user login process. The access to login form will be restricted for signed in users by checking if the php session is set or not.

<?php
session_start();

if(isset($_SESSION['usr_id'])!="") {
    header("Location: index.php");
}

include_once 'dbconnect.php';

//check if form is submitted
if (isset($_POST['login'])) {

    $email = mysqli_real_escape_string($con, $_POST['email']);
    $password = mysqli_real_escape_string($con, $_POST['password']);
    $result = mysqli_query($con, "SELECT * FROM users WHERE email = '" . $email. "' and password = '" . md5($password) . "'");

    if ($row = mysqli_fetch_array($result)) {
        $_SESSION['usr_id'] = $row['id'];
        $_SESSION['usr_name'] = $row['name'];
        header("Location: index.php");
    } else {
        $errormsg = "Incorrect Email or Password!!!";
    }
}
?>

This file produces a login form similar to this.

php-login-system-script

Login form requires users to provide login credentials (email & password). Both the input fields are mandatory and notify user to fill out if left blank.

php-login-system-form-validation

Here too we sanitize the data and check for user authentication against database records. If it fails, we notify the user with error message like this,

php-login-system-form-validation-error

If the user credentials are legitimate then we create session and store user's id and name in the session variable and redirect to index.php.

Index.php

This is the home page of our application and shows login and sign up menu links for visitors and for signed in members will show their name and logout link respectively.

<?php
session_start();
include_once 'dbconnect.php';
?>

</html>

Logout.php

This file will be fired up when the user clicks on the logout link. The user logout process is fairly simple. It destroy session and unset the user data from the session.

<?php
session_start();

if(isset($_SESSION['usr_id'])) {
    session_destroy();
    unset($_SESSION['usr_id']);
    unset($_SESSION['usr_name']);
    header("Location: index.php");
} else {
    header("Location: index.php");
}
?>

Once you created all the above files, run the app and you will see the home page like this,

php-login-registration-system-home
index.php - Home Page

Now click on the sign up link and you will be redirected to the user registration form,

php-registration-form

Now enter the form details and submit the sign up button. If everything goes right then you will be registered and notified with a message like this,

php-registration-success

Now go to the login form through the login link.

Provide the login credentials and you will be signed in and redirected to the index page.

signed-in-user-home-page
index.php as signed-in user

Click on logout to sign out the session and you will be taken back to the index page again.

home page
After Log out

Download

That's it. You have successfully created user login and registration system in php and mysql.

The login and register buttons on the menu are not there and are replaced by a single button with 3 lines, I do not recognize this and it doesn't seem to correspond to the code.

  24. First thanks for the great tutorial. I've been trying to figure this out for days!! and you are the first resource that I've had success with. Registration is working for me but my login has a bug in it. The system logs me in when I enter a valid user email address and password but the redirect doe not get me to the index.php page, which is at /testdb/index.php/, and I can access it via the browser.

    When I login as a valid registered user the code is inserting "login.php" in the path statement and the browser takes me to /testdb/login.php/index.php, which generates the following error in the browser "ERR_TOO_MANY_REDIRECTS"

    After logging in if I access the index page directly, the page shows the user is signed in.

    Any idea what may be wrong with my code?

    Thanks in advance for whatever assistance you may be able to provide.

    1. Hi! You have to just change the connection details to that of the live server.

      mysqli_connect("localhost", "myusername", "mypassword", "testdb")

      Like 'localhost' should be your live server name/ip and username and password also should be changed. Just get those details from your hosting service if you have trouble.

      Hope this helps.
      Cheers.

    1. Hi! To provide access to only logged-in user, add the below code at the top of the page.

      session_start();
      if(isset($_SESSION['usr_id'])) {
          header("Location: index.php");
      }

  34. everything works great, thank you. is there an easy way to prevent the user from being registered until i approve there account? i suppose i would need to integrate a php mailer?

    ReplyDelete
  35. The code works PERFECT with me. However, I need to know what I should change in the codes to do 2 things:

    1- Make the Password field requires a complex password with minimum 8 characters.
    2- Make the Name field accepts other languages like Arabic.

    Thanks for your help.

    }


    if (!$error) {
    if(mysqli_query($con, "INSERT INTO users(name,email,password,job) VALUES('" . $name . "', '" . $email . "', '" . md5($password) . "', '" . $job . "')")) {

    1. Hey sorry for late reply. I haven't used custom css for any of my tutorials. Only Bootstrap css. Just download it from their official site and make use of it or try loading from cdn.

  38. This remains one of the best introductions to getting a user registration system online - FANTASTIC WORK! Can I ask, is there ANY chance you could also do a password reset for lost/forgotten passwords? I'm keen to stay within the great work you've done, but struggling a bit on how to do this. Please! :) THANK YOU for your great work.

  39. Do you do customisations? I would like to add an email verification process when a new user registers, and the Password Reset feature in case a user forgot the password.
