User Registration and Login Script with PHP and MySQL

By
In this tutorial we will discuss how to create user registration and login management system with PHP and MySQL in simple procedural way. user registration and login system is most important thing for any kind of web applications and it is common thing too, and session plays important role in this type of system, for that we have to use session, In this tutorial, we are going to use PHP sessions to keep user login status, see the live demo of php mysql login signup script or you can also download this script, and i have updated this script with php server side validations, so how to do login php let’s start.
User Registration and Login Script with PHP and MySQL

First of all create a database and table as below.
you can create it by importing following sql command in to your phpmyadmin.
database : dbtest
table : users

--
-- Database: `dbtest`
--

-- --------------------------------------------------------

--
-- Table structure for table `users`
--

CREATE TABLE IF NOT EXISTS `users` (
  `userId` int(11) NOT NULL AUTO_INCREMENT,
  `userName` varchar(30) NOT NULL,
  `userEmail` varchar(60) NOT NULL,
  `userPass` varchar(255) NOT NULL,
  PRIMARY KEY (`userId`),
  UNIQUE KEY `userEmail` (`userEmail`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;
copy-paste the above sql code into phpmyqdmin to create database and table.

Now we have to create following files..
–dbconnect.php
–register.php
–index.php
–home.php
–logout.php

dbconnect.php

contains code for localhost connection and database selection.

<?php

 // this will avoid mysql_connect() deprecation error.
 error_reporting( ~E_DEPRECATED & ~E_NOTICE );
 // but I strongly suggest you to use PDO or MySQLi.
 
 define('DBHOST', 'localhost');
 define('DBUSER', 'root');
 define('DBPASS', '');
 define('DBNAME', 'dbtest');
 
 $conn = mysql_connect(DBHOST,DBUSER,DBPASS);
 $dbcon = mysql_select_db(DBNAME);
 
 if ( !$conn ) {
  die("Connection failed : " . mysql_error());
 }
 
 if ( !$dbcon ) {
  die("Database Connection failed : " . mysql_error());
 }


NOTE : we have to start session in all the pages.
>> I have used here simple HTML5 required attribute to validate the following register and login forms.
if you want to know more about validations click here : validations

register.php

contains simple html form and few lines of php code.
save this file as ‘register.php‘, this file contains simple html form with all the required registration fields except user id because it’s auto incremented and some php code for registering a new user. all the user registration process can be done in this single php file.

<?php
 ob_start();
 session_start();
 if( isset($_SESSION['user'])!="" ){
  header("Location: home.php");
 }
 include_once 'dbconnect.php';

 $error = false;

 if ( isset($_POST['btn-signup']) ) {
  
  // clean user inputs to prevent sql injections
  $name = trim($_POST['name']);
  $name = strip_tags($name);
  $name = htmlspecialchars($name);
  
  $email = trim($_POST['email']);
  $email = strip_tags($email);
  $email = htmlspecialchars($email);
  
  $pass = trim($_POST['pass']);
  $pass = strip_tags($pass);
  $pass = htmlspecialchars($pass);
  
  // basic name validation
  if (empty($name)) {
   $error = true;
   $nameError = "Please enter your full name.";
  } else if (strlen($name) < 3) {
   $error = true;
   $nameError = "Name must have atleat 3 characters.";
  } else if (!preg_match("/^[a-zA-Z ]+$/",$name)) {
   $error = true;
   $nameError = "Name must contain alphabets and space.";
  }
  
  //basic email validation
  if ( !filter_var($email,FILTER_VALIDATE_EMAIL) ) {
   $error = true;
   $emailError = "Please enter valid email address.";
  } else {
   // check email exist or not
   $query = "SELECT userEmail FROM users WHERE userEmail='$email'";
   $result = mysql_query($query);
   $count = mysql_num_rows($result);
   if($count!=0){
    $error = true;
    $emailError = "Provided Email is already in use.";
   }
  }
  // password validation
  if (empty($pass)){
   $error = true;
   $passError = "Please enter password.";
  } else if(strlen($pass) < 6) {
   $error = true;
   $passError = "Password must have atleast 6 characters.";
  }
  
  // password encrypt using SHA256();
  $password = hash('sha256', $pass);
  
  // if there's no error, continue to signup
  if( !$error ) {
   
   $query = "INSERT INTO users(userName,userEmail,userPass) VALUES('$name','$email','$password')";
   $res = mysql_query($query);
    
   if ($res) {
    $errTyp = "success";
    $errMSG = "Successfully registered, you may login now";
    unset($name);
    unset($email);
    unset($pass);
   } else {
    $errTyp = "danger";
    $errMSG = "Something went wrong, try again later..."; 
   } 
    
  }
  
  
 }

Now, after creating registration page, then move ahead to create login page.
i’ve written this login script with little bit security to prevent your website from sql injection.



index.php/login page

this file also contains html form with two input box which will take user email and user password entered by user and then after submitting the form, the php code will match that user email and password combination in database and when it finds both results in table then it will start a session and allow user to access home page else it will show appropriate message.

<?php
 ob_start();
 session_start();
 require_once 'dbconnect.php';
 
 // it will never let you open index(login) page if session is set
 if ( isset($_SESSION['user'])!="" ) {
  header("Location: home.php");
  exit;
 }
 
 $error = false;
 
 if( isset($_POST['btn-login']) ) { 
  
  // prevent sql injections/ clear user invalid inputs
  $email = trim($_POST['email']);
  $email = strip_tags($email);
  $email = htmlspecialchars($email);
  
  $pass = trim($_POST['pass']);
  $pass = strip_tags($pass);
  $pass = htmlspecialchars($pass);
  // prevent sql injections / clear user invalid inputs
  
  if(empty($email)){
   $error = true;
   $emailError = "Please enter your email address.";
  } else if ( !filter_var($email,FILTER_VALIDATE_EMAIL) ) {
   $error = true;
   $emailError = "Please enter valid email address.";
  }
  
  if(empty($pass)){
   $error = true;
   $passError = "Please enter your password.";
  }
  
  // if there's no error, continue to login
  if (!$error) {
   
   $password = hash('sha256', $pass); // password hashing using SHA256
  
   $res=mysql_query("SELECT userId, userName, userPass FROM users WHERE userEmail='$email'");
   $row=mysql_fetch_array($res);
   $count = mysql_num_rows($res); // if uname/pass correct it returns must be 1 row
   
   if( $count == 1 && $row['userPass']==$password ) {
    $_SESSION['user'] = $row['userId'];
    header("Location: home.php");
   } else {
    $errMSG = "Incorrect Credentials, Try again...";
   }
    
  }
  
 }
?>

        </div>
   
    </form>
    </div> 

</div>

</body>
</html>
<?php ob_end_flush(); ?>


after registration page and login page we need to create ‘home‘ page which shows users dashboard, which is authentic page and this page cannot access without logging in.

home.php

this page shows welcome message of logged in user with username and a hyper link to logout the user and redirects the ‘logout.php’ page.

<?php
 ob_start();
 session_start();
 require_once 'dbconnect.php';
 
 // if session is not set this will redirect to login page
 if( !isset($_SESSION['user']) ) {
  header("Location: index.php");
  exit;
 }
 // select loggedin users detail
 $res=mysql_query("SELECT * FROM users WHERE userId=".$_SESSION['user']);
 $userRow=mysql_fetch_array($res);
?>

logout.php

this page contains only few lines of php code to unset and destroy the current logged in users session, and after destroying the session the page automatically redirect to the ‘index/login’ page.

<?php
 session_start();
 if (!isset($_SESSION['user'])) {
  header("Location: index.php");
 } else if(isset($_SESSION['user'])!="") {
  header("Location: home.php");
 }
 
 if (isset($_GET['logout'])) {
  unset($_SESSION['user']);
  session_unset();
  session_destroy();
  header("Location: index.php");
  exit;
 }

  8. I've had a few problems with this code, specifically the registration and log-in pages. When I hit submit on the registration page after filling out the form, I keep getting a message that there was an error and that registration failed.

    I decided to test the log-on page, and created some records in the DB (using PHPmyadmin) and then using this information to log in. Again I got an error that I could not log-in, despite the log-in information being correct.

    Any ideas what the problem is here? It seems to a problem with connecting to the DB.

  10. Hi,
    how can you protect multiple pages apart from the index.php?
    does the session apply to any file in the same directory (or sub directories) or does the in the head of the index.php need to be included in every file that i want protected?
    thanks.

    1. yes by defining a session you can protect the pages you want...

    1. Hi Dineas,

      Yes above home page code is for all users and as you have three types of users in your system , for that you have to create role based login system so , give roles to the users and create three pages for users,
      alter your table and add role field then in login code fetch user role and redirect them to specific page.
      and please use PDO or MySQLi.

    1. Hi Omar....

      Make sure you have put the "header("Location: home.php")" function on login button click
      like this :

      if(isset($_POST['btn-login']))
      {
      $email = mysql_real_escape_string($_POST['email']);
      $upass = mysql_real_escape_string($_POST['pass']);
      $res=mysql_query("SELECT * FROM users WHERE email='$email'");
      $row=mysql_fetch_array($res);

      if($row['password']==md5($upass))
      {
      $_SESSION['user'] = $row['user_id'];
      header("Location: home.php");
      }
      else
      {
      echo "wrong details !!!";
      }

      }

      hence this is working script...

  67. I have a question about the Logout.php portion, the second part of the IF statement seems redundant to me.

    else if(isset($_SESSION['user']) != "")

    You have an unset check as the first condition, so it will only move on if $_SESSION is set, why wouldn't you leave the second condition as ($_SESSION != "")? Seems redundant to repeat the set check. However i can understand the set and not empty check in one line

    ReplyDelete
    Replies
    1. Hi there, the first condition will never let you open "logout.php" if the user is not logged in. and the second else condition, if user is logged in he cannot open "logout.php" so in the both condition user cannot open logout.php page directly. it will work silently for destroying session.

  81. Hi,

    The registration works well, however the login doesn't. To prove this I removed the md5# from the source code and the table so I can test properly. I have tried every possible way to try and make it work. Screenshots below.

    After registering: https://gyazo.com/b9dffa8524917d54000586d6ece30282
    Changed the password type to text to prove this: https://gyazo.com/6f0bcbf6fdedbeec43260bec17e8fb52

    Please give me a solution to this, thanks.
