CodeIgniter base_url (), the link in localhost gives me a live server


I am working on web page in CodeIgniter in my localhost but this webpage is also in live server.

It uses base_url() for all links.

For example:

<link rel="stylesheet" href="<?= base_url() ?>assets/style.css">
<script src="<?= base_url() ?>assets/jquery-ui.min.js"></script>
<a href="<?= base_url() ?>show/edit/other">

When I click on link in localhost it gives mi live server address, so I can't do anything in localhost.

Can somebody help me please?

You can create two folders inside application/config one for production(live server) and one for development(localhost)

  • development => application/config/development
  • production => application/config/production

Then copy any file in the main application/config folder and paste it into both development and production folders.


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


$config['base_url'] = '';

Based on your ENV constant in index.php it will load settings from either production or development folders. So if ENV == 'development' the settings in application/config/development will get used.

If you want a relative path to your assets, add this to the HEAD of your html

<base href="<?php echo base_url();?>" />

Then you can just ref your assets like so

<link rel="stylesheet" href="assets/styles.css" />
