I've noticed many sites are able to use a username or page title as an action. How is this done?
For example instead of www.example.com/users/my_username (where the users action 开发者_开发问答is generic and responsible for fetching user data) how could I make this www.example.com/my_username?
Thanks very much.
All modern frameworks follow router ideology. So for this task you just need to write yet another route.
How to do this - is a specific task for particular framework.
In CodeIgniter it would be a route like zerkms said. You can define routs in /system/application/config/routes.php. Here's the CodeIgniter documentation on URI routing. Essentially you take the part of the URL (such as the username) specified in your route as a variable and can do a lookup against your db with it.
With mod_rewrite you could write a rule that redirects www.example.com/user/my_username (or without the user) to www.example.com/user/?name=my_username.
