Removing index.php in CodeIgniter using .htaccess file - .htaccess

Question

I'm currently developing a website using CodeIgniter and I recently stumbled upon a routing & .htaccess problem.
Basically, the structure of my simple website (let's call my project 'CIExample' for the sake of simplicity) is as follow:
-Home
-About Us
-Our Service
-News
-Contact Us
which I implemented using a Page controller. This controller has 5 functions which called respective page's view, i.e:
Home(), which calls the view 'Home'
About(), which calls the view 'About Us' and so on..
Previously, to access 'Home', I would need to type http://localhost/CIExample/index.php/page/home into the url window, but after setting the following routes I was able to remove the 'page' (classname) part:
$route['default_controller'] = 'page/home';
$route['home'] = 'page/home';
$route['about'] = 'page/about';
$route['service'] = 'page/service';
$route['news'] = 'page/news';
$route['contact'] = 'page/contact';
However, the tricky part came when I try to remove the 'index.php'.
I want to be able to access the home page by typing http://localhost/CIExample/home.
So I did a lot of searches on CI forum/tutorial/stack overflow, and found some codes for .htaccess file:
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ index.php/$1 [L]
or http://ellislab.com/forums/viewthread/197675/#929904
I tried both codes but none works..
http://localhost/CIExample/home would direct me to 404 not found page, but http://localhost/CIExample/index.php/home would work just fine.
I wonder what went wrongs? Is it my routes.php or .htaccess or both?
Thanks.
Note: I've also changed my 'config/config.php' file -> $config['index_page'] = '';
EDIT:
Finally it works!
After tweaking the config.php file in config folder and set the following $config['uri_protocol'] = 'PATH_INFO'; (from 'AUTO').
Available Values:
| 'AUTO' Default - auto detects
| 'PATH_INFO' Uses the PATH_INFO
| 'QUERY_STRING' Uses the QUERY_STRING
| 'REQUEST_URI' Uses the REQUEST_URI
| 'ORIG_PATH_INFO' Uses the ORIG_PATH_INFO
Dunno what's the different but according to one of the comments in http://www.jotorres.com/2011/12/removing-index-php-from-url-in-codeigniter/, the same code might/might not work in the production server.
Anyone can explain the reason maybe?

Answer 1

You just need to paste this in your .htaccess file:
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]
</IfModule>
and make this alternation to your application/config/config.php file:
$config['index_page'] = '';

Answer 2

I have use following method, it is working perfectly in UBUNTU...!!
First of all verify that you have enabled mod_rewrite (you can verify using phpinfo()) in your index.php file.
IF DISABLED mod_rewrite then RUN:
1. sudo a2enmod rewrite
2. sudo gedit /etc/apache2/sites-available/defaut
just replace "AllowOverride None" to "AllowOverride All" in Tag(<'Directory /var/www/'>)
3. Then please run sudo service apache2 restart
Ok Good...
Now in your root directory of Codeigniter -> Find .htaccess file, if not found then press ctrl+h , still not found then create a file .htaccess
In .htaccess
Paste following code :
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /ROOT DIRECTORY NAME/
# Directs all EE web requests through the site index file
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>
Ok finally just replace ROOT DIRECTORY NAME
DONT FORGOT TO REMOVE index.php from application/config/config.php file
Make that line like
$config['index_page'] = '';

I use this htaccess for all my CodeIgniter projects. It supports subfolders too.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
#Removes access to the system folder by users.
#Additionally this will allow you to create a System.php controller,
#previously this would not have been possible.
#'system' can be replaced if you have renamed your system folder.
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php?/$1 [L]
#When your application folder isn't in the system folder
#This snippet prevents user access to the application folder
#Submitted by: Fabdrol
#Rename 'application' to your applications folder name.
RewriteCond %{REQUEST_URI} ^application.*
RewriteRule ^(.*)$ /index.php?/$1 [L]
#Checks to see if the user is attempting to access a valid file,
#such as an image or css document, if this isn't true it sends the
#request to index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>
<IfModule !mod_rewrite.c>
# If we don't have mod_rewrite installed, all 404's
# can be sent to index.php, and everything works as normal.
# Submitted by: ElliotHaughin
ErrorDocument 404 /index.php
</IfModule>

In your system/application/config/config.php, Change
$config['index_page'] = "index.php";
To
$config['index_page'] = "";
And in your .htaccess,add this:
RewriteEngine on
RewriteCond $1 !^(index\.php|images|stylesheets|scripts|robots\.txt)
RewriteRule ^(.*)$ /index.php/$1 [L]
