Why Isn't My CodeIgniter base_url() Function Working?

Troubleshooting base_url() Function in CodeIgniter

When attempting to utilize the base_url() function within a CodeIgniter project, it may sometimes yield unexpected results. To address this, it's crucial to ensure the URL Helper has been correctly loaded.

1. Use Autoload File:
   Within your application/config/autoload.php file, verify that the following line is included (around line 67):

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

2. Manual Loading:
   If the Autoload file method is not preferred, you can manually load the URL Helper within your controller:

   $this->load->helper('url');

3. Understanding Return Value:
   It's important to note that base_url() does not automatically print or echo its value. Instead, it returns the base URL of the website, which can then be echoed:

   echo base_url();

4. Base URL Configuration:
   Ensure that the base_url property within application/config/config.php is not empty. If left blank, CodeIgniter will attempt to guess the correct URL based on the environment.
