title: CodeIgniter: Is it possible to remove the controller & function from the URL using routes or .htaccess?
body: <p>I have a database consisting of a table called "pages".
  I have a controller called "site" and a function called "page"... <a href="http://website.com/site/page/page_id" rel="nofollow">http://website.com/site/page/page_id</a>. </p>
  
  <p>In the page function it currently looks for the 3th URI segment (page_id), then finds and matches this to a page row in the database and displays the row results.</p>
  
  <p>My question is, is it possible to route/change my URL from <a href="http://website.com/site/page/page_id" rel="nofollow">http://website.com/site/page/page_id</a> to 
  <a href="http://website.com/page_id" rel="nofollow">http://website.com/page_id</a>. And then obviously change my function to find the first URI segment??</p>
  
  <p>My current .htaccess file removes the "index.php", and looks like this:</p>
  
  <pre><code>&lt;IfModule mod_rewrite.c&gt;
  RewriteEngine On
  RewriteBase /db
  
  #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]
  
  #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
  #This last condition enables access to the images and css folders, and the robots.txt file
  #Submitted by Michael Radlmaier (mradlmaier)
  RewriteCond $1 !^(index\.php|images|robots\.txt|css)
  RewriteRule ^(.*)$ index.php/$1 [L]
  &lt;/IfModule&gt;
  
  &lt;IfModule !mod_rewrite.c&gt;
  # If we don’t have mod_rewrite installed, all 404’s
  # can be sent to index.php, and everything works as normal.

  ErrorDocument 404 /index.php
  &lt;/IfModule&gt;
