codeigniter Let's start: Hello World Let's use the controller a little more
Example
Now we'll try going for a little more complex example, using the capabilities of the controller to fill in the view.
Here is our view:
/application/views/hello_world.php
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Hello World</title>
</head>
<body>
<h1><?php echo $greetings;?></h1>
</body>
</html>
Now we have a placeholder for our greetings to be displayed.
Here is how we change the controller in order for this to work:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Hello_world extends CI_Controller {
public function __construct() {
parent::__construct();
}
public function greetings(){
$data = array('greetings'=>'Hello World');
$this->load->view('hello_world',$data);
}
}
The $data array is prepared with the information to be injected into the view, using the same label (greetings) that has been recalled inside the view.
The final result is the same as with the first example, but we are now using more of the potentiality of the framework!
