.htaccess shortening code not working

Question

i would like to shorten http://fpmls.ca/index.php/user/user_postdetail/index/14 to http://fpmls.ca/index.php/post_14.html.

user_postdetail is a controller and index is a function of this controller 14 is id(dynamic)

My .htaccess code is:

RewriteEngine On           
RewriteRule ^post_([0-9]+).html$ index.php/user/user_postdetail/index/$1

I am getting the URL, but "404 Page Not Found: The page you requested was not found." is shown in that page. Any one please help me

Answer 1

Using routes.php in the configuration directory, define the following rule:

$route['post_(:num).html'] = 'user/user_postdetail/$1';

Alternatively, you can leave out the .html and make the your URI suffix in the app's configuration.
