Secure Registration and Login Script with PHP and MySQL using CodeIgniter and Ion Auth

This is a secure registration and login form created using CodeIgniter and Ion Auth. I highly recommend using Ion Auth to secure the login form of your site as this is already tested and proven to prevent SQL Injection. In addition, I use Bootstrap to improve the design of the form. Here’s the instruction on how to setup CodeIgniter, Ion Auth and Bootstrap. 1. Download CodeIgniter

• Extract the files to your server. Example if you’re using XAMPP, extract it to D:\xampp\htdocs

2. Download Ion Auth

• Extract the files under application folder. Example if you extract CodeIgniter in D:\xampp\htdocs\ci-ionauth-reg then extract Ion Auth under D:\xampp\htdocs\ci-ionauth-reg\application

3. Download Bootstrap

• Extract Bootstrap under D:\xampp\htdocs\ci-ionauth-reg. You can choose to create another folder as long as it is relative to the path of the CodeIgniter file. Example, extract the folder under D:\xampp\htdocs\ci-ionauth-reg\assets or D:\xampp\htdocs\ci-ionauth-reg\bootstrap.

Configure CodeIgniter and Ion Auth

Before we configure CodeIgniter, first import the SQL file included with Ion Auth. Open phpMyAdmin as follows: http://localhost/phpmyadmin/ Create a database name loginreg (short for login and registration). Click Import tab and browse the file located under D:\xampp\htdocs\ci-ionauth-reg\application\sql. Choose the file named ion_auth.sql if you’re using MySQL as your database. Open config.php under D:\xampp\htdocs\ci-ionauth-reg\application\config folder. Change the following info into: $config['base_url'] = 'http://localhost:8080/ci-ionauth-reg'; $config['index_page'] = ''; Open database.php under D:\xampp\htdocs\ci-ionauth-reg\application\config folder. Change the following info into: 'hostname' => 'localhost', 'username' => 'root', 'password' => '', 'database' => 'loginreg', Note: I just change some few lines of code of Auth.php under controllers folder like: $this->_render_page('header_view', $this->data); $this->_render_page('auth/login', $this->data); $this->_render_page('footer_view', $this->data); header_view and footer_view includes the code to include Bootstrap file. To open the login form and registration form, visit the following URLs: http://localhost/ci-ionauth-reg/auth/login http://localhost/ci-ionauth-reg/auth/create_user Username: [email protected] Password: password You can also change the registration URL from http://localhost/ci-ionauth-reg/auth/create_user to http://localhost/ci-ionauth-reg/register by setting the routes. Example, open routes.php under config folder. $route['register'] = 'auth/create_user'; You can add the line after $route['default_controller'] = 'welcome'; If you have any question, don’t hesitate to as under the comments below.
