To do this just follows the following steps:

  • Open config.php from system/application/config directory and replace

$config[‘index_page’] = “index.php” by $config[‘index_page’] = “”

  • Create a “.htaccess” file in the root of CodeIgniter directory (where the system directory resides), open the file using your favorite text editor, write down the following script and save it:

Windows change to

RewriteEngine on
RewriteBase /ci/
RewriteCond $1 !^(index\.php|<span style="color: #ff0000;">js</span>|css|images|javascript)
RewriteRule ^(.*)$ index.php/$1 [L]

Mac change to

RewriteEngine on
RewriteCond $1 !^(index\.php|resources|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]
  • In some case the default setting for uri_protocol does not work properly. To solve this problem just replace

$config[‘uri_protocol’] = “AUTO” by $config[‘uri_protocol’] = “REQUEST_URI” fromsystem/application/config/config.php
