What is Codeigniter?
• CI is a powerful PHP framework with a very
small footprint, built for PHP coders who need
a simple and elegant toolkit to create fullfeatured web applications

About CodeIgniter
● CodeIgniter is a lightweight web application
framework written in PHP that adopts the modelview-controller approach to development
● Open source
● Well-supported by an active community
● Excellent “by example” documentation
● Easy to configure
● Supports multiple database
● Was built by EllisLab.

Controllers
Controller is simply a class file that is named in
a way that can be associated with a URI
– localhost/index.php/hello/

 Function
◦ function can be add to the controller and called by
the URI segment
 localhost/index.php/hello/index

Controllers
In This Particular Code
www.your-site.com/index.php/first/bdosdn/world
<?php
class First extends Controller{
function index() {
echo “<h1> Hello CUET !! </h1> “;
}
function

bdosdn(

$location ) {
echo “<h2> Hello $location !! </h2>”;

}
}
?>
// Output Will be “Hello world !!”

• Note:
• The ‘Index’ Function always loads by default. Unless there is a second
segment in the URL
•Class names must start with an Uppercase Letter.

VIEWS
• View is simply a web page, or a page
fragment, like a header, footer, sidebar, etc.
– views can flexibly be embedded within other
views (within other views, etc., etc.)
– views are never called directly, they must be
loaded by a controller

• Loading a View
– $this->load->view('name');
• name is the name of your view file

VIEWS


A Webpage or A page Fragment



Should be placed under “application/views”

web_root/myci/system/application/views/myview.php
<html>
<title> My First CodeIgniter Project</title>
<body>
<h1> Welcome ALL … To My .. ::: First Project :::
. . . </h1>
</body>
</html>

$this->load->view(‘myview’);

Data Passing to a VIEW from Controller
function index() {
$var = array(
‘full_name’ => ‘Amzad Hossain’,
‘email’ => ‘tohi1000@yahoo.com’
);
$this->load->view(‘myview’, $var);
}

<html>
<title> ..::Personal Info::.. </title>
<body>
Full Name : <?php echo $full_name;?>
E-mail
: <?php echo $email;?> <br />
</body>
</html>

<br />

• Models are PHP classes that are designed to
work with information in a database
– $this->load->model('Model_name');

Models

Models Should be placed Under “application/models/”
class Log extends CI_Model
{
public function sample($data)
{
$this->load->database();
$q=$this->db->query("SELECT * from tbl_user where username='$data[username]'
and password='$data[password]'");
$res = $q->result();
if (!empty($res)) {
