Tutorial − Introduction

+ +

This tutorial is intended to introduce you to the CodeIgniter framework and the basic principles of MVC architecture. It will show you how a basic CodeIgniter application is constructed in step-by-step fashion.

+ +

In this tutorial, you will be creating a basic news application. You will begin by writing the code that can load static pages. Next, you will create a news section that reads news items from a database. Finally, you'll add a form to create news items in the database.

+ +

This tutorial will primarily focus on:

Model-View-Controller basics
Routing basics
Form validation
Performing basic database queries using "Active Record"

+ +

The entire tutorial is split up over several pages, each explaining a small part of the functionality of the CodeIgniter framework. You'll go through the following pages:

Introduction, this page, which gives you an overview of what to expect.
Static pages, which will teach you the basics of controllers, views and routing.
News section, where you'll start using models and will be doing some basic database operations.
Create news items, which will introduce more advanced database operations and form validation.
Conclusion, which will give you some pointers on further reading and other resources.

+ +

Enjoy your exploration of the CodeIgniter framework.

Now that the database and a model have been set up, you'll need a method to get all of our posts from our database. To do this, the database abstraction layer that is included with CodeIgniter — Active Record — is used.
