Random Coding

Basic usage

Unzip Codeigniter 2.20 into a folder called ‘Codeigniter’

1. You need a controller (application/controller/pages.php)


<?php

class Pages extends CI_Controller {

	public function view($page = 'home')
	{

		if ( ! file_exists(APPPATH.'/views/pages/'.$page.'.php'))
	{
		// Whoops, we don't have a page for that!
		show_404();
	}

	$data['title'] = ucfirst($page); // Capitalize the first letter

	$this->load->view('templates/header', $data);
	$this->load->view('pages/'.$page, $data);
	$this->load->view('templates/footer', $data);
	}
}

<?php

class Pages extends CI_Controller {

public function view($page = 'home')

{

if ( ! file_exists(APPPATH.'/views/pages/'.$page.'.php'))

{

// Whoops, we don't have a page for that!

show_404();

}

$data['title'] = ucfirst($page); // Capitalize the first letter

$this->load->view('templates/header', $data);

$this->load->view('pages/'.$page, $data);

$this->load->view('templates/footer', $data);

}

2. You need a view method (application/views/pages/home.php)


Hello World

Hello World

3. and maybe a header (application/views/templatesfooter.php)


<html>
<head>
	<title><?php echo $title ?> - Codehavens CodeIgniter Basics</title>
</head>
<body>
	<h1>CodeIgniter Basics</h1>

<html>

<head>

<title><?php echo $title ?> - Codehavens CodeIgniter Basics</title>

</head>

<body>

<h1>CodeIgniter Basics</h1>

4. and footer (application/views/templates/footer.php)


<strong>&copy; 2014</strong>
</body>
</html>

</body>

</html>

5. Run the url in your browser
http://localhost/Codeigniter/index.php/pages/view/home
(without a .php extension)
You should then be able to see an output that has a title(name of page), header and content of home.php, with a footer.
