It will show you how a basic CodeIgniter application is constructed in step-by-step fashion.</p> <p>In this tutorial, you will be creating a <strong>basic news application</strong>. 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.</p> <p>This tutorial will primarily focus on:</p> <ul> <li>Model-View-Controller basics</li> <li>Routing basics</li> <li>Form validation</li> <li>Performing basic database queries using "Active Record"</li> </ul> <p>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:</p> <ul> <li>Introduction, this page, which gives you an overview of what to expect.</li> <li><a href="static_pages.html">Static pages</a>, which will teach you the basics of controllers, views and routing.</li> <li><a href="news_section.html">News section</a>, where you'll start using models and will be doing some basic database operations.</li> <li><a href="create_news_items.html">Create news items</a>, which will introduce more advanced database operations and form validation.</li> <li><a href="conclusion.html">Conclusion</a>, which will give you some pointers on further reading and other resources.</li> </ul> <p>Enjoy your exploration of the CodeIgniter framework.</p> </div> <!-- END CONTENT --> <div id="footer"> <p> Previous Topic: <a href="../overview/goals.html">Goals</a> · <a href="#top">Top of Page</a> · <a href="../index.html">User Guide Home</a> · Next Topic: <a href="static_pages.html">Static pages</a> </p> <p><a href="http://codeigniter.com">CodeIgniter</a> · Copyright © 2006 - 2014 · <a href="http://ellislab.com/">EllisLab, Inc.</a></p> </div> </body> </html>
