What is CodeIgniter?
CodeIgniter is an Application Development Framework – a toolset – for PHP website developers.
Its purpose is to let you construct projects much faster than if you were programming code from the start by providing a rich set of libraries for common activities, as well as a simple interface and logical structure to access these libraries.
By reducing the amount of code required for a given operation, CodeIgniter allows you to focus more creatively on your project.

Conclusion
This lesson did not cover all that a full-fledged tutorial would, but it did introduce you to the most important modules, developing controllers, and models.
We hope that our CodeIgniter instructional login page (form) offered you some insight into some of CodeIgniter’s basic design patterns, which you may build on.
Frequently Asked Questions
How does this CodeIgniter login or registration system work?
User signup form (with email verification optional), password hashing via PHP password_hash() / password_verify(), login form with session start, remember-me cookie, logout, password reset via emailed token. Foundation block for any user-facing capstone.
What CodeIgniter and PHP versions does this project require?
Most projects in this batch use CodeIgniter 3 (CI3 – the dominant version on tutorial sites) which runs on PHP 5.6 to PHP 8.1. A few newer projects use CodeIgniter 4 which requires PHP 7.4+. Check the system/CodeIgniter.php file or composer.json for exact version. To run: extract to your htdocs (XAMPP/WAMP/Laragon), update application/config/database.php with your MySQL credentials, import the included .sql file via phpMyAdmin, browse to the project folder URL.
How do I set up the database for this CodeIgniter project?
Open phpMyAdmin (or MySQL client), create a new empty database (typical names: ci_school, ci_pos, etc.). Import the included .sql file via the Import tab. Edit application/config/database.php: set ‘hostname’ to localhost, ‘database’ to the new DB name, ‘username’ and ‘password’ to your local MySQL credentials. If using CodeIgniter 4: edit .env with database.default.* settings.
Can I use this CodeIgniter project for a BSIT capstone or thesis?
Yes, but extend it. A bare CRUD app is too narrow for full capstone scope. Add: user roles via session checks, reports/dashboards (Chart.js + AJAX), PDF exports (TCPDF library), email notifications (CodeIgniter Email library), real domain extension (analytics, audit log, multi-branch support). Pair with Chapter 1-5 documentation matching your panel’s rubric.
Why am I getting ‘An Error Was Encountered’ or ‘404 Page Not Found’ errors?
Three common CodeIgniter issues: (1) Wrong base_url in application/config/config.php, set $config[‘base_url’] to your actual project URL (e.g. http://localhost/myproject/). (2) Apache mod_rewrite not enabled, run sudo a2enmod rewrite (Linux) or check XAMPP/WAMP config. (3) Missing .htaccess in project root with proper RewriteRule. For DB errors: verify credentials in application/config/database.php match your MySQL setup.
Where can I find more CodeIgniter projects with source code?
Browse the CodeIgniter Projects hub for the full library. For broader PHP capstones see PHP Projects (300+ vanilla PHP + MySQL systems). For modern PHP MVC alternatives see Laravel Projects (74 systems). For BSIT-focused capstone idea lists see 150 Best Capstone Project Ideas.
