After numerous requests, today we are launching a new screencast series on Nettuts+ that will focus exclusively on the CodeIgniter PHP framework. Over the course of about 10 videos, I’ll teach you exactly how to use this framework. Ultimately, we’ll work our way up to building a custom CMS. Without further ado, here’s day one!

    Hi, I followed the tutorial and when I tried to go to http://localhost:8888/ci/index.php/site/, I get a blank page. Any idea what could be missing? I’m relatively new to PHP. Thanks!

      I found the answer below. Reason is I need to extends CI_Controller instead of Controller. Thanks to Ben!

    hello people!! i am trying out the code of the video but for some reason i am not seeing any results coming from the get(‘test’)… in the getall function the if statement shows the query as empty, also i get an error message saying Message: Undefined variable: data (site_model, function getall, “return $data” line)

    How to make the first echo work? I am 2.1.3. http://localhost:8080/ci/index.php/site

    <?php

    class Site extends CI_Controller {

    function index() {

    echo 'hello world';
    }

    This is the first video I’ve watch in your series about CI. It’s very
    usefull for me and others.I have followed your guide from the start to
    the end of your video.But I don’t know why my localhost noticed
    error ”

    Severity: Notice

    Message: Undefined property: Site_model::$db

    Filename: models/site_model.php

    Line Number: 6

    Fatal error: Call to a member function get() on a non-object in D:xampphtdocsciapplicationmodelssite_model.php on line 6

    ”

    Even if I copy your source code to htdocs folder, It noticed the same error :(

    Can any one (or the author) help me to resolved my problem? Thanks in advance
