Hi

I'm writing a function in my controller; this is supposed to take in a form, process it, register the user in DB, send a confirmation email etc etc.

to avoid this function to be too cluttered, I was thinking of calling some sub-functions (eg:

function registration()
{
  //process form..

  _insertInDb($formdata)

  _send_mail($address);

  //load confirmation view..
}

function _send_mail($to)
{
  //code here
}

function _insertInDb($formdata)
{
  //other code here...
}

I'm not sure whether writing all the functions in the controller would be best practice -maybe I should insert all 'supporting' function (eg send_mail and insertInDb in this example) in another file and then import them?

This would probably make the controller much more readable.. what's your view?
