Open application/config/config.php and set your base_url(). E.g: $config['base_url'] = 'http://localhost/code/';
Create .htaccess file under /code folder (Where application and system folder is) like below:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
create .htaccess file in \code\
as
RewriteEngine On
RewriteBase /code/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
and in config/config.php
$config['base_url'] = 'http://localhost/code';
Hope it will help you.
