URI routing in codeigniter

I have my CI site working well except the URL's are a bit ugly. What approach should I take to enable me to ro开发者_开发问答ute what is displaying at:

http://domain.com/content/index/6/Planning

to the url:

http://domain.com/Planning

I'm confused about whether this should be be done in the routes file or in my .htaccess

Thanks

There are couple of ways to set up config/routes.php, the suitability depends on your requirements.

1. Route for each page, if you have just a couple of pages that you want to route:

   $route['Planning'] = 'content/index/6';  
   $route['Working'] = 'content/index/7';  
   // etc.
   

2. You can use fallback url, that will match after all other route rules - that means you must set rules that might match this rule before the fallback rule. It also means you loose ID, and have to query database based on the title:

   $route['register'] = 'register'; // this would match the fallback rule  
   $route['([a-z-A-Z1-9_]+)'] = 'content/index/$1'; // letters, numbers and underscore  
   // you'll receive "Planning" as parameter to Content::index method
   

3. Or you can have policy that all urls to content must start with capital letter, in that case you don't have to worry about other route rules

   $route['([A-Z]{1}[a-z-A-Z1-9_]+)'] = 'content/index/$1';  
   // again, you'll receive "Planning" as parameter to Content::index method
   

4. You still want the numerical ID, so you don't have to change the controller/model:

   $route['(\d+)/[a-z-A-Z1-9_]+'] = 'content/index/$1';  
   // routes now look uglier: http://domain.com/6/Planning

you should be able to accomplish that with some of the examples on this page
