How to Correctly Set the Base URL in CodeIgniter to Avoid 'Object Not Found' Errors?

Determining the Base URL in CodeIgniter

When using CodeIgniter, accessing resources and URLs within the application can often involve including the full path. To reduce this code duplication and improve portability, it's recommended to establish a base URL that can be used throughout the application.

In your case, you've encountered difficulties while attempting to set up the base URL. You modified the $config['base_url'] in config.php but encountered "object not found" errors upon accessing resources.

To resolve this issue, you need to ensure that the base URL is set correctly in config.php. Navigate to the config.php file and update the $config['base_url'] value as follows:

$config['base_url'] = 'http://localhost/Appsite/website/';
$config['index_page'] = '';

This will set the base URL for your application to 'http://localhost/Appsite/website/'. If you're deploying the application online, ensure you update the base URL accordingly.

Additionally, you can modify the .htaccess file (located outside the application folder) to remove 'index.php' from URLs. This will give your URLs a cleaner appearance:

RewriteEngine on
RewriteCond  !^(index\.php|assets|image|resources|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/ [L,QSA]

After setting these configurations, you can access URLs and resources within your application using the base_url() helper. This helper can be loaded by adding the following line to your autoload.php file:

$autoload['helper'] = array('url');

Now, you can use the base_url() helper to generate the base URL for your application:

<a href="<?php%20echo%20base_url();?>contollerName/methodName"> click here</a>

Accessing images:

<img  src="<?php%20echo%20base_url();?>images/images.PNG%E2%80%9D>

Accessing%20CSS:

<link%20rel=" stylesheet type="text/css" href="<?php%20echo%20base_url();?>assets/css/style.css" alt="How to Correctly Set the Base URL in CodeIgniter to Avoid 'Object Not Found' Errors?" >

By following these steps, you can set up the base URL in CodeIgniter and access application resources and URLs more efficiently.
