A view is just a web page i.e combination of HTML and CSS also called front view, or a page fragment, like a header, footer, sidebar, etc. In fact, views can flexibly be embedded within other views (within other views, etc., etc.)
In codeigniter Views are never called directly, Views must be loaded by a controller in an MVC framework, the Controller acts as a traffic cop, so it is responsible for fetching a particular view with certain data.
In this post we will discuss about Passing data from controller to view in codeigniter.
Creating a View
Let’s start a simple blog site . So create
Header.php
Menu.php
Body.php
Footer.php
Header.php
<html> <head> <title>Technolila blog</title> </head>
Menu.php
<nav> <li>Home</li><li>Blog</li> </nav>
Body.php
<body> <h1>Welcome to Technolila!</h1> </body>
Footer.php
<footer> <p>Developed By: Technolila.com</p> </footer> </html>
Now save the file in your application/views/ director or you can save this file in a folder within views folder like main application/views/main.

Loading a View
In codeigniter you can load view by following method,
$this->load->view('name');
The .php file extension does not need to be specified unless you use something other than .php.
Loading multiple views
In codeigniter we can load multiple view according to our needs by $this->load->view() this method, they all appears in our front end page accordingly.
For example
<?php
Class Tech extends CI_Controller {
public function index()
{
$data['page_title'] = 'Technolila Blogs';
$this->load->view('header');
$this->load->view('menu');
$this->load->view(‘body’, $data);
$this->load->view('footer');
}
}
?>
Storing Views within Sub-directories
Like above we said , view file can be saved in views/main folder so for this we need to include the directory name loading the view Example $this->load->view(‘directory_name/file_name’); And above code look like
<?php class Tech extends CI_Controller {
public function index(){
$data['page_title'] = 'Technolila Blogs';
$this->load->view('main/header');
$this->load->view('main/menu');
$this->load->view('main/body’, $data);
$this->load->view('main/footer');
} } ?>
Adding Dynamic Data to the View
Generally in codeigniter data passed from controller to view through array or object. Generally array or an object in the second parameter of the view loading method. Code looks like
$data = array( 'title' => 'Technolila', 'heading' => 'My Heading', 'message' => 'My Message' ); $this->load->view(body, $data);
Let’s try it with Our controller file. Open it add this code:
<?php class Tech extends CI_Controller {
public function index() {
$data['page_title'] = 'Technolila Blogs';
$data['footertext'] = 'Power by Technolila.com';
$data['menu'] = 'Home';
$data['content'] = 'Welcome to Technolila';
$this->load->view('main/header');
$this->load->view('main/menu');
$this->load->view('main/body’, $data);
$this->load->view('main/footer');
} } ?>
Now in open view file header,menu,body,footer
Header.php
<html> <head> <title><?php echo $page_title; ?></title> </head>
Menu.php
<nav> <li><?php echo $menu; ?></li> </nav>
Body.php
<body> <h1><?php echo $content; ?></h1> </body>
Footer.php
<footer> <p><?php echo $footertext; ?></p> </footer> </html>
Creating Loops
Suppose we have more than one menu like home,blog,contact then how can we pass menu variable . Here we need loops in view page. Let’s see example
<?php class Tech extends CI_Controller {
public function index() {
$data['page_title'] = 'Technolila Blogs';
$data['footertext'] = 'Power by Technolila.com';
$data['menu'] = array('Home', 'Blog', 'Contact');
$data['content'] = 'Welcome to Technolila';
$this->load->view('main/header');
$this->load->view('main/menu');
$this->load->view('main/body’, $data);
$this->load->view('main/footer');
} } ?>
Now open menu.php and write Menu.php
<nav> ?php foreach ($menu as $item){?> <li><?php echo $item;?></li> <?php }?> </nav>
