How do you handle 404 errors in CodeIgniter?

In CodeIgniter, handling 404 errors— which occur when a requested page is not found— can be customized to improve user experience. Here’s how you can do it effectively:

1. Customizing the show_404() Method

You can customize the default behavior for 404 errors by overriding the show_404() method in a controller. This allows you to specify what happens when a page isn’t found. Here’s a simple

Example

<?php
class MyController extends CI_Controller {
    public function show_404() {
        // Load a custom 404 view
        $this->load->view('custom_404');
    }
}
?>

Creating a Custom 404 Error View

To enhance the user experience, you can create a custom 404 error view. This view can contain helpful information, such as navigation links to other pages or a search bar. Here’s how you can do it:

  • Create a new file named custom_404.php in the application/views/errors/ directory.
  • Design the view to include user-friendly content. For example:

Example

<?php
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Page Not Found</title>
</head>
<body>
    <h1>Oops! Page Not Found (404)</h1>
    <p>Sorry, but the page you were looking for doesn't exist.</p>
    <a href="<?php echo site_url(); ?>">Return to Home</a>
</body>
</html>
?>

By customizing the show_404() method in a controller and creating a user-friendly error view, you can handle 404 errors in CodeIgniter more effectively. This not only informs users that the page they requested is unavailable but also guides them to other resources on your site.
