how to configure codeigniter mod_rewrite on wamp?

There are total 4 easy steps that you need to follow (I am considering you have WAMP installed on C:\wamp and CodeIgniter has been to extracted to C:\wamp\www\codeigniter\):

1. Create a .htaccess file as mentioned in http://codeigniter.com/wiki/mod_rewrite but replace RewriteBase / with RewriteBase /codeigniter/ according to your path.
2. Place this file in C:\wamp\www\codeigniter\ folder
3. Open the httpd.conf file either from WAMP->Apache->httpd.conf or manually from C:\wamp\bin\Apache\conf\httpd.conf then locate the line #LoadModule rewrite_module modules/mod_rewrite.so and replace the hash(#) from the beginning so that the complete line becomes LoadModule rewrite_module modules/mod_rewrite.so. Now Restart Apache.
4. Finally open the file C:\wamp\www\codeigniter\application\config\config.php and replace $config['index_page'] = "index.php"; with this $config['index_page'] = "";

Your URLs should now be clean example http://localhost/codeigniter/blog etc.

In case it didn't work, refer to the official wiki: http://codeigniter.com/wiki/mod_rewrite

1. Follow the steps above (ans 1) to get mod_rewrite enabled.

2. To check if enabled, use the WAMPManager menu like so:wampmanager -> Apache -> Module (Scroll the list and make sure is ticked)

3. create/edit .htaccess on your root CI folder where index.php located.

   <IfModule mod_rewrite.c>    RewriteEngine On    RewriteCond %{REQUEST_FILENAME} !-f    RewriteCond %{REQUEST_FILENAME} !-d    RewriteRule ^(.*)$ index.php/$1 [L]</IfModule>

   CodeIgniter URLs

4. Edit config.php to $config['index_page'] = '';

create/edit .htaccess on your root CI folder (where index.php is located)

<IfModule mod_rewrite.c>    RewriteEngine On    RewriteCond %{REQUEST_URI} ^system.*    RewriteCond %{REQUEST_FILENAME} !-f    RewriteCond %{REQUEST_FILENAME} !-d    RewriteRule ^(.*)$ index.php?/$1 [L]    RewriteRule ^(.*)$ /index.php?/$1 [L]</IfModule>
