Where to use form helper?

[eluser]Unknown[/eluser]
Hi,

I have a question about form helper.

I know that the logic can't be separated from the presentation entirely, although that is the focus of MVC.

I'm using the form helper to create a form, but I don't know if I should be putting this in my view or my controller, and then passing $data to the view and echoing it out there.

Any input?
