How to customize the 404 page in CodeIgniter?

To customize the 404 page in CodeIgniter, follow these steps:

1. Create a new view file for your custom 404 page. You can name it something like 404.php and save it in your application/views directory.
2. Customize the content of the 404 page in this view file. You can add any error message, images, or styling you want to use for your custom 404 page.
3. Open the application/config/routes.php file in your CodeIgniter project.
4. Add a route for the 404 error page by adding the following line to the routes.php file:

1

$route['404_override'] = 'errors/not_found';

1. Create a new controller file named Errors.php in your application/controllers directory.
2. In the Errors.php controller file, create a method named not_found that loads the custom 404 view file you created earlier. Here is an example of how you can do this:

<?php
class Errors extends CI_Controller {
    public function not_found() {
        $this->load->view('404');
    }
}

1. Save the Errors.php controller file and make sure that your custom 404 view file is properly named and located in the application/views directory.
2. Test your custom 404 page by navigating to a non-existent page in your CodeIgniter project. You should now see your custom 404 page instead of the default CodeIgniter 404 error page.

By following these steps, you can easily customize the 404 page in your CodeIgniter project to match your website's design and branding.

What is the recommended error reporting level for 404 pages in CodeIgniter?

In CodeIgniter, it is recommended to set the error_reporting level to E_ERROR in the production environment for 404 pages. This means that only fatal errors will be displayed, helping to ensure that sensitive information is not leaked to users.

What is the best way to design the layout of the custom 404 page in CodeIgniter?

Designing the layout of a custom 404 page in CodeIgniter involves customizing the view file and configuring the error handling in the controller. Here is a step-by-step guide to designing the layout of the custom 404 page in CodeIgniter:

1. Create a custom 404 view file: Create a new view file in the views folder of your CodeIgniter application, named 404.php. This file will contain the HTML code for the custom 404 page layout, including a message informing the user that the page they are looking for does not exist.
2. Customize the 404 view file: In the 404.php view file, you can add additional HTML elements such as a header, footer, navigation menu, and styling using CSS to match the overall design of your website. You can also include a search bar or links to popular pages to help users navigate to other parts of your site.
3. Configure the error handling in the controller: In the controller file responsible for handling errors, such as the default controller or a custom error controller, you need to set up the code to load the custom 404 view file when a page is not found. You can do this by using the show_404() function provided by CodeIgniter.

Here is an example of how to configure the error handling in the controller:

1

3

5

public function show_404_page()
{
  $this->output->set_status_header('404');
  $this->load->view('404');
}

In this example, when a page is not found, the show_404_page() method is called, which sets the HTTP status code to 404 and loads the custom 404 view file.

1. Testing the custom 404 page: To test the custom 404 page, you can intentionally enter a non-existent URL in your browser and verify that the custom 404 page is displayed with the layout you designed.

By following these steps, you can effectively design the layout of the custom 404 page in CodeIgniter and provide a user-friendly error page for visitors when they encounter a page not found.
