<h1>Tutorial<a class="headerlink" href="#tutorial" title="Permalink to this headline">¶</a></h1>
|
|
<p>This tutorial is intended to introduce you to the CodeIgniter4 framework
|
|
and the basic principles of MVC architecture. It will show you how a
|
|
basic CodeIgniter application is constructed in a step-by-step fashion.</p>
|
|
<p>If you are not familiar with PHP, we recommend that you check out
|
|
the <a class="reference external" href="https://www.w3schools.com/php/default.asp">W3Schools PHP Tutorial</a> before continuing.</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 class="simple">
|
|
<li>Model-View-Controller basics</li>
|
|
<li>Routing basics</li>
|
|
<li>Form validation</li>
|
|
<li>Performing basic database queries using CodeIgniter’s “Query Builder”</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 class="simple">
|
|
<li>Introduction, this page, which gives you an overview of what to
|
|
expect.</li>
|
|
<li><a class="reference internal" href="static_pages.html"><span class="doc">Static pages</span></a>, which will teach you the basics
|
|
of controllers, views and routing.</li>
|
|
<li><a class="reference internal" href="news_section.html"><span class="doc">News section</span></a>, where you’ll start using models
|
|
and will be doing some basic database operations.</li>
|
|
<li><a class="reference internal" href="create_news_items.html"><span class="doc">Create news items</span></a>, which will introduce
|
|
more advanced database operations and form validation.</li>
|
|
<li><a class="reference internal" href="conclusion.html"><span class="doc">Conclusion</span></a>, which will give you some pointers on
|
|
further reading and other resources.</li>
|
|
</ul>
|
|
<p>Enjoy your exploration of the CodeIgniter framework.</p>
