One form, many actions

[eluser]Sector[/eluser]
Hello, once again I'm stuck on something, and not being able to find a solution that's not hackerish is nagging at me.

I have a form, and it contains many checkboxes. (one for each item in a table).
At the end of that form, you can press multiple submit buttons. The form is a POST
form that points to the controller action with method delegate. I envisioned this method because I cannot let a form point to multiple URLs.

What I want to happen is: if a person checks a few checkboxes and presses the 'delete' button, I want to delegate page to reroute to action/delete, with exactly the same POST array.

How can I accomplish this with Code Igniter?

Thanks very much in advance!
