Form Validation And URL Validation

[eluser]ralfo[/eluser]
Hi all,

I'm really liking codeigniter, love the simplicity and rapid development aspects.

Now, I want to use the form validation class to validate ALL data coming into my application.

This is fine when the data coming in is from a form (of course lol).

However, I want to use it to validate the URL segments too.

Can this be done?

Would be really neat and tidy if it could, otherwise I will be using the form validation class to validate form data, but my own custom classes/functions to validate URL segments (eg domain.com/order/book/345 - test that 345 is within the specified bounds using the form validation class that already exists).

Please advise
