While I have a progressively growing dislike of frameworks, I'll give you the following advice from what I've observed in other frameworks: Normally, you build a controller class elsewhere which inherits from the base controller class. Let's say it's a controller for blog entries. Now, you populate the (child) controller with the methods you'll need for each action. Like a method to delete blog entries. A method for adding blog entries. Etc. At that point, you have to decide if you're going to use server redirection or standard URLs to get to your controller. That is: http://mysite.com?controller=blog&action=add or http://mysite.com/blog/add/ The latter method is preferred by those who believe there's such a mythical beast as "pretty URLs" preferred by search engines (there isn't). It requires the use of .htaccess files and Apache's mod_rewrite, which you may not have in a shared hosting environment. Hopefully that helps. Paul -- Paul M.
