codeigniter Base url in Codeigniter Setting your base url in Codeigniter
Example
You will need to set your base URL in application/config/config.php
If it is not set, then CodeIgniter will try to guess the protocol and path to
your installation, but due to the security concerns the hostname will be set
to $_SERVER['SERVER_ADDR'] if available, or localhost otherwise.
The auto-detection mechanism exists only for convenience during
development and MUST NOT be used in production!
$config['base_url'] = '';
It should be filed like
$config['base_url'] = 'http://localhost/projectname/';
$config['base_url'] = 'http://www.example.com/';
Always good to use / at end of base_url
When you do not set your base URL you might run into some errors where you can not load your CSS, images, and other assets items. And also you might have trouble submitting forms as some users have come across.
Update
If you do not want to set your base URL another way is.
Create a new core file in application/core/MY_Config.php
And paste this code
<?php
class MY_Config extends CI_Config {
public function __construct() {
$this->config =& get_config();
log_message('debug', "Config Class Initialized");
// Set the base_url automatically if none was provided
if ($this->config['base_url'] == '')
{
if (isset($_SERVER['HTTP_HOST']))
{
$base_url = isset($_SERVER['HTTPS']) && strtolower($_SERVER['HTTPS']) !== 'off' ? 'https' : 'http';
$base_url .= '://'. $_SERVER['HTTP_HOST'];
$base_url .= str_replace(basename($_SERVER['SCRIPT_NAME']), '', $_SERVER['SCRIPT_NAME']);
}
else
{
$base_url = 'http://localhost/';
}
$this->set_item('base_url', $base_url);
}
}
}
