Official documentation
Frequently Asked Questions
What does this CodeIgniter CRUD example demonstrate?
Basic Create, Read, Update, Delete operations against one Model. Foundation tutorial showing CodeIgniter MVC structure: routes, controllers loading models, form validation library, view templates. Use as a learning step before tackling a full 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.
