Basic CodeIgniter Framework is a beginner course in building web applications with CodeIgniter 4.7, from installation, routing and MVC to databases, forms, file uploads, email, membership with Shield and protection against common vulnerabilities. It suits people with some PHP experience, students, teachers and IT staff who look after CodeIgniter websites.
CodeIgniter is a lightweight PHP framework with a simple structure that is easy to install and quick to learn, which makes it a good starting point for anyone new to frameworks. Splitting work along MVC lines keeps code tidy, lets several people work together and allows later changes without affecting other parts. The current release is CodeIgniter 4.7, which requires PHP 8.2 or later and supports PHP 8.5.
This course builds a solid CodeIgniter 4 foundation step by step, from installation, configuration, routing, controllers and views to the database with migrations, the query builder and models. Learners build create, update and delete features, validate forms, upload files, send email, manage sessions and cookies, add membership with Shield and defend against common vulnerabilities, then finish with a small online shop workshop and deployment. (3 days, 6 hours per day, 18 hours in total, Beginner level.)
Course Details
This course is the 2026 edition of Basic CodeIgniter Framework. It runs for 3 days, 6 hours per day (18 hours in total, 09:00-16:00), as lectures with labs and a workshop. Beginner level. This edition uses CodeIgniter 4.7 on PHP 8.5, replaces the old autoload and base URL settings with the .env file and Composer, and adds migrations, entities, filters, membership with Shield and deployment. It keeps the everyday basics: databases, forms, file uploads, email, sessions, cookies, caching, multiple languages and security. The course focuses on fundamentals for people new to frameworks, unlike PHP OOP and CodeIgniter Framework, which builds an OOP foundation and focuses on REST APIs and SQL Server. Learners take home a lab guide, source code for every lab and their workshop project.

The controller receives the request for a URL defined in the routes, calls the model to read or save data, then passes the data to the view, an HTML and PHP file that renders the page. This separation lets you change the design without touching the logic and reuse models across pages. Shared helper code lives in helpers or libraries, and checks before a page is reached are done with filters.
For SQL injection, use the query builder, models or query binding, which keep values separate from the SQL instead of joining strings yourself. For XSS, escape data before output with esc() every time and consider enabling a Content Security Policy. Turn on CSRF protection through a filter to block forged form posts from other sites, store passwords with password_hash() and hide error details in production.
Create a form with enctype set to multipart/form-data and a file input. In the controller, check the file with validation rules such as uploaded, is_image, mime_in and max_size, get it with $this->request->getFile(), confirm it with isValid(), then store it with store() or move() and save the file name to the database. Always restrict file type and size, and keep CodeIgniter up to date to receive security fixes.
It suits people with some PHP experience who want to start using a framework, students, teachers, lecturers, IT staff and system administrators, and people maintaining CodeIgniter 3 systems. You should be able to write basic PHP, HTML and CSS, understand website design and general database use, and be comfortable with Windows or macOS.
You will be able to install and configure CodeIgniter 4.7, structure an MVC application, create tables with migrations, build create, update and delete features with models, validate forms, handle file uploads and email, manage sessions and cookies, add membership with Shield, defend against XSS, SQL injection and CSRF, and put the site into production. Participants receive a Certificate of Completion with its own number that can be verified online.
Yes. It can be run in-house for your team, with examples adapted to your work, such as practising on a PHP system your team maintains or planning a move from CodeIgniter 3 to CodeIgniter 4. You can request a quotation from this page, or contact us on LINE @itgenius or by phone on 02-570-8449.

PHP and MySQL still power a great many websites and business systems, yet much of the sample code around is written the old way: SQL built by joining strings, passwords stored unsafely, functions that have since been removed, or jQuery for everything. Sites…
Many PHP websites start as procedural code that is quick to write and easy to follow. As the system grows, functions end up scattered across every file, SQL is mixed with HTML, and a change in one place breaks several others until nobody dares to touch it.…
