User Registration in PHP with Login: Form with MySQL and Code Download

by Vincy. Last modified on July 19th, 2022.

User registration with login is an essential component of a website. I will help you build a simple, light-weight user registration in PHP with login backed by MySQL database. Read on!

There are lots of PHP components for user registration available on the Internet. But these contain heavy stuff with lots of dependencies.

The code should be lightweight, secure, feature-packed and customizable. The example you are going to see now will have these attributes and will be sufficient for any website.

User Registration in PHP with Login Form

What is inside?

  2. Create user registration and login form
  3. Registration and login form validation

Example code for user registration in PHP

In this example, I have created user registration in PHP with the login script.

On the landing page, it shows a login form with a signup link. The registered user can enter their login details with the login form. Once done, he can get into the dashboard after successful authentication.

If the user does not have an account, then he can click the signup option to create a new account.

The user registration form requests username, email, password from the user. On submission, PHP code allows registration if the email does not already exist.

This example code has client-side validation for validating the entered user details. And also, it includes contains the server-side uniqueness test. The user email is the base to check uniqueness before adding the users to the MySQL database.

Create user registration and login form

I have created three HTML view login form, registration form and the dashboard for this code.

Below HMTL code is for displaying the login form to the user. In this form, it has two inputs to allow the user to enter their username and password.

Without these details, a validation code will not allow the login to proceed. The login form tag’s on-click attribute is with loginValidation(). This function contains the login form validation script.

On submitting this login form, the PHP code will validate the user. If the users clear the authentication, then it will redirect him to the dashboard.

If the user attempts to log in with the wrong data, then the code will display a login error message in the login form. If you want to limit the failed login attempts, the linked article has an example of that.

Following is a user registration form to get minimal user data from the user. All form fields are mandatory.

It will pass-through a JavaScript validation before processing the user registration in PHP.

On submitting the registration form fields, it will invoke the signupValidation() JavaScript method. In this method, it validates with the non-empty check, email format, and the password match.

After validation, the PHP registration will take place with the posted form data.

    require_once './Model/Member.php';

Registration and login form validation

I have used JavaScript to validate the form before submitting the request to PHP backend.

On invalid data submission, the code will return a boolean false. It forces the user to enter the required fields by highlighting them.

Process user registration in PHP

After submitting the form details, it processes user registration in the PHP code.

This code uses default form submit to post data to the PHP. If you want the user registration code with AJAX, then we have to prevent the default submit with a script.

I have added this code at the beginning of the user-registration-form.php. It checks if the user submitted the form. Then, it invokes the registerMember() method defined in the Member model.

I have shown the Member model class code below. It contains all the functions related to this user registration and login example.

In the registerMember() function, it checks if the posted email already exists. If so, it truncates the registration flow and returns the error. Otherwise, it creates the Insert query to add the member record into the MySQL database.

The loginMember() function checks if there is any match for the entered login details. If the match found, it clears the authentication and allows the user to access the dashboard.

Model/Member.php

<?php
namespace Phppot;

    private $ds;

PHP login authentication code

The code in the login-form.php file above invokes the authentication function after login.

User dashboard

This is the user dashboard code. It shows a welcome message with the logged-in member name. It also has an option to logout from the current session.

At the top of the home.php file, I have done the session based authorization check. This is to ensure that, users who do not have access to this page are redirected to login page.

If a not-logged-in user tries to access this page, the session will be cleared and he will be redirected to login page.

home.php

<?php
session_start();
if (isset($_SESSION["username"])) {
    $username = $_SESSION["username"];
    session_write_close();
} else {
    // since the username is not set in session, the user is not-logged-in
    // he is trying to access this page unauthorized
    // so let's clear all session variables and redirect him to index
    session_unset();
    session_write_close();
    $url = "./index.php";
    header("Location: $url");
}

?>

Logout

Following logout script is common code. You can use it any of your PHP projects. It clears the complete user session and redirects the user to the home / login page.

logout.php

<?php
// clear all the session variables and redirect to index
session_start();
session_unset();
session_write_close();
$url = "./index.php";
header("Location: $url");

DataSource.php

This class is a wrapper for MySQL / mysqli with PreparedStatement. You can use it in any of your PHP and MySQL projects. It is available in the download project zip linked at the end of this tutorial.

MySQL database script

Below SQL script shows the MySQL database table’s create statement. It also has the specification for the key and indexes.

User registration MySQL schema

    Hi, awesome guide. Is it possible to use this guide and incorporate the OTP registration somehow?

    Regarding OTP code, how do I give option to either receive by SMS or email? For SMS OTP, what do I need to do to set it up?

    Thanks

    • Vincy says:

      Hi Rashmi,

      For OTP registration, you need to get service from a OTP service provider. Then use their API to integrate it.

  • Manpreet Singh says:

    Thanks you.
    Very nice article for PHP professional.

    I have successfully registered.

  • Sahmain says:

    May I ask what is the use of the $paramType = ‘s’?

  • Abhishek says:

    I want to become a good php developer, how can I start my journey?

    • Vincy says:

      Hi Abhishek,

      Choose a PHP book and learn it systematically. Then start developing a project and learn through coding.

  • Chittaranjan Ghosh says:

    AS usual your tutorials are really good to learn from.
    I was wondering if you use any framework for your projects, as it seems to me that you are confident enough in custom coding that hardly requires any framework.

    • Vincy says:

      Hi Ghosh,

      Thank you. I do not use frameworks as much as possible. I wish to code always in a light-weight way with lesser footprint.

  • Prof. Mbah Anthony says:

    I am developing a software with thousands of fieldsets whose inputs are submitted individually. Can you help me with the process? I’ll be glad if you can.

  • Mervin says:

    Wow…Vincy you simply magic. I am trying to create a savings and credit system. The rest of the system is almost done. And so far so good.

  • Jeff says:

    Not only is the really clean code, it’s well explained, and for me at least, nicely free of all sorts of other randomly confusing stuff, like depending on lots of huge libraries but only using a tiny bit of each library, which often makes it hard to see what is going on and what’s randomly extra. Thanks again, I am getting back into web development after many years away from it and your tutorials are very clear to me. Thanks again.

  • tony bonell says:

    Your code as an example helps too many people at all levels.

    thank you for your codes

  • dennis says:

    A big help for a beginner like me and wants to continue my in progress in programming , i know programming must be good in mathematics Thanks for the author of this code

  • Chris says:

    Am very much impressed by this tutorial, thanks alot admin, as long as you will be here to answer our questions.

    I have been using WordPress, and they have a function called get_current_user_id();

    How can i create such function or get the details of the user that has logged in and viewing the dashboard using your code above?

    • Vincy says:

      Hi Chris,

      This project is written with plain PHP. To use this in WordPress, lot of changes should be done. If you are using WordPress, then you should probably using the login and registration provided with the CMS itself instead of building something custom.

  • Nichola says:

    Thanks for these works.

  • Corey says:

    I love everything about this site, detailed guide on various php jobs. Keep it up vicy

    But want know if there is way to keep the validation function in another page, and then called the function like this

    if(isset(‘submitbook’)) {
    echo book_validation ();
    }

    Does having both php and html in One page, poses a security

    • Vincy says:

      Hi Corey,

      Thank you. Sure, you can have both PHP and HTML on same page. It does not have any security issues. Having said that, try to separate the business logic and view as much as possible. It will help for maintenance and enhancements.

    • Vincy says:

      Hi Jarvis,

      In the download bundle, there is a SQL file and it has the database structure. Import that file using PHPMyAdmin or any database client. Then your database is setup and ready.

    Thank you so much for the code you supplied! I appreciate it so much!
    When I run the code, user-registration.php gives an error.
    The error_log shows this:

    [07-May-2021 09:46:15 Africa/Johannesburg] PHP Warning: call_user_func_array() expects parameter 1 to be a valid callback, first array member is not a valid class name or object in /home/engincoz/eztermz/testing/login/lib/DataSource.php on line 165

    PHP Fatal error: Uncaught Error: Call to a member function execute() on bool in /home/engincoz/eztermz/testing/login/lib/DataSource.php:100

    seems to be this statement in dataSource.php giving problems:
    [165] call_user_func_array(array($stmt,’bind_param’), $paramValueReference);

    Any suggestions?

    • Vincy says:

      Hi Christoph,

      Looks like you have given the wrong username and password to connect to the database.

    Wow this is so good to be true, Thanks man

      Hi Karthick,

      You are have a very old version of PHP and you should upgrade to solve this issue.

  • Raju says:

    Hi, Vincy thanks a lot for this tutorial. I want forgot password page for this script. Please provide…

  • Sachithra says:

    Great work…Hey thank you… Can you help me to reset password in this website.

  • Roystan says:

    HI, thanks for the script. I installed it but issue when I tried to register a user. “Page is not working with HTTP Error 500”.Not sure where is the problem here. Can you help? thanks

  • Volker says:

    thank you so much Vincy. It saved me days of work.

  • Khalid says:

    Is this Script hack proof?

    • Vincy says:

      Hi Khalid,

      Yes, it uses PreparedStatement and protected from SQL injection issues.

  • Patrick says:

    wow!!! thank you Vincy i’m appreciated for your work and thank you for help me. God bless you.

  • John Rambo says:

    Nice work, I copy ur code and do some modification to meet my need. If possible, can I set the no activity session timeout? for example if no activity for 15 minutes, session will expired.

    • Vincy says:

      Hi John,

      Yes you can do that easily. When the user login, store the login timestamp and use the timediff and invalidate the user session.

  • Chenard says:

    hi,

    For some reason, I could not get it right. The page after registration came out blank. I know I make a mistake somewhere as it might due to not connecting to the mydatabasePHP or something.
    Any advice? Thank you

    • Vincy says:

      Hi Chenard,

      All you need to do is proper setup of database and specify the DB configuration in Datasource file and the user registration will happen without any issues.

  • john says:

    many thanks my friend GOD BLESS YOU

  • Miya says:

    Here, the registration form gets automatically submitted when the page refreshed. So, after a registration, if page is refreshed, it simply shows the error ‘Username already exists’. How to avoid this automatic resubmission of form happening when the page refreshes? Please help.

    • Vincy says:

      Hi Miya,

      You can redirect to a page after submission. In that case to display the succession message use session. Then this resubmission on refresh will not happen. This is a common pattern and solution.

      Either redirect or AJAX is the solution.

  • Ugochukwu Anusi says:

    Pls where should I place the DataSource.php File

  • nicholas says:

  • Marc says:

    What software did you use for Php? :C

      Hi Marc,

  • Shah says:

    I’m a beginner in PHP and doing pet clinics system for final year project university. I want to use your code for guidance in PHP. Do I have to change the database name?
    Thank you for sharing your knowledge and great work.

    • Vincy says:

      Hi Shah,

      Yes, you should change the database name to what you already have in Datasource.php

  • Keza says:

    hello how can i do to display the email too after the username on the welcome page? thank you

    • Vincy says:

      In member.php, $_SESSION[“username”] = $memberRecord[0][“username”]; this line stores the username in session. You can use the same technique. Store the registered user’s email in session and get that in the welcome page and display it.

  • Emily Favour says:

    Thanks so much for this. I’m new to PHP but this help me so much. Please I want users to be redirected to a new page after successful registration rather than viewing the “You have registered successfully” message. How to I do that?
    Thanks in anticipation.

    • Vincy says:

      Hi Emily,

      Refer Member.php, public function loginMember() – this function and if ($loginPassword == 1) { this part of the if block takes care of redirecting the user after login. You can use that part and do redirect the user after registration.

  • Ebonge Pierre says:

    Thanks so much for this. I wish to have my users redirected to another page after successful registration. How do I do that?
    Thanks

    • Vincy says:

      Hi Pierre,

      In the file Model.php, there is a line that redirects after success “./home.php”. Change it to the file to which you want to redirect.

  • Thato says:

    Hi Thanks for your simple and easy to follow tutorials, if i wanted to use phone number instead of email can i just change the emails values to number? or would i have to start from scratch with input for numbers?

    • Vincy says:

      Hi Thato,

      Welcome. Using phone number in this registration and login is possible. But for validation, you need to send OTP and validate the phone number. To send OTP you will need access to a third-party API provider.
