One example, that we often see, is something along the following lines in the controller:
if($this->User->save($this->data)) {
$this->Session->setFlash(... some stuff for the view ... );
$this->redirect(array('action'=>'success'));
}
$this->Session->setFlash(... some stuff for the view ... );
$this->redirect(array('action'=>'success'));
}
If all we are doing is displaying a “success” page back to the user, do we really need to bother with a redirect()?
To me it seems a little easier to do:
if($this->User->save($this->data)) {
$this->set('arrayOfMessages', $myPreviouslyPreparedArrayOfMessages);
$this->render('success');
}
$this->set('arrayOfMessages', $myPreviouslyPreparedArrayOfMessages);
$this->render('success');
}
Not really a big deal one way or another, but something to consider (especially for those very high traffic servers ;)).
P.S. As some readers pointed out, the obvious draw back is that $this->render() will cause the data re-submit prompts when refreshing or going back in the browser.
