About Lesson
The View is responsible for the presentation of the Model (data) in a certain format. A view is a simple web page created using HTML. We can call a view by using a Controller.
How to create a view?
<html>
<head>
<title>About Us</title>
</head>
<body>
<h1>infovistar.com</h1>
</body>
</html>
Save the file as about_us.php in your /app/Views directory.
How to load a view?
The view() method is used to load a view in a Controller.
| Load a view in CodeIgniter 3 | Load a view in CodeIgniter 4 |
|---|---|
| $this->load->view(‘about_us’); | echo view(‘about_us’); |
Now we can set this view to our about_us() method in the Home.php controller.
<?php
namespace App\Controllers;
class Home extends BaseController {
public function about_us() {
echo view('about_us');
}
}
?>
Add dynamic data to the View
We can pass data from the controller to the view by way of an array or an object in the second parameter of the view method.
Here is an example using an array:
$data = array(
'title' => infovistar.com',
'heading' => About Us',
'message' => 'Welcome to CodeIgniter‘'
);
echo view('about_us', $data);
Example:
Controller: Home.php
<?php
namespace AppControllers;
class Home extends BaseController {
public function about_us() {
$data = array(
'title' => 'infovistar.com',
'heading' => 'About Us',
'message' => 'Welcome to CodeIgniter'
);
echo view('about_us', $data);
}
}
?>
View: about_us.php
<html>
<head>
<title><?php echo $title; ?></title>
</head>
<body>
<h1><?php echo $heading; ?></h1>
<h6><?php echo $message; ?></h6>
</body>
</html>
