How to Fix CodeIgniter Base URL for Production Deployment?

Fixing CodeIgniter Base URL for Production Deployment

Deploying a CodeIgniter application from a development environment to a production server can result in URL issues. When moving the application to a new address, the base URL needs to be adjusted accordingly.

Suppose your development environment had the URL testurl.com and you've now moved it to someurl.com/mysite. Upon trying to access a function like /home/test, it incorrectly directs you to someurl.com/home/test, which is not the desired behavior. The correct URL should be someurl.com/mysite/home/test.

Solution:

To resolve this issue, ensure that the $config['base_url'] parameter is set correctly in your config.php file. This parameter specifies the absolute base URL of your application, including the protocol.

Proper Syntax:

<code class="php">$config['base_url'] = "http://somesite.com/somedir/";</code>
Copy after login

Absolute URL:

Note that the base URL should be absolute, including the http:// or https:// protocol. This will ensure that your URLs are consistent and work across different environments.

Use of URL Helper:

If you're using the CodeIgniter URL helper, calling base_url() will output the above string. You can pass arguments to base_url() or site_url() to generate specific URLs relative to the base URL.

Example:

<code class="php">echo base_url('assets/stylesheet.css'); // http://somesite.com/somedir/assets/stylesheet.css
echo site_url('mycontroller/mymethod'); // http://somesite.com/somedir/index.php/mycontroller/mymethod</code>
Copy after login
