Re: Moving nested if statements out of the view.

Not sure if this is what you want to do; but in one place in my app
I've done some validation on an array of fields in my controller and
used the results of this to build a custom error message string that I
then set to the session:

if (!empty($this->data)) {
$err_msg = $this->_check_kpis($this->data);
if (strcmp($err_msg, "") != 0)
{
$this->Session->setFlash(__($err_msg, true));
}
else
{
// Save the form
}

before rendering the view again. The $err_msg that comes back from my
function call contains the customized message.
