Quick Little Tip Regarding Cakephp forms

Occasionally when I am coding something in Cake that requires a form, I run into a problem if I use something like

if( !empty($this->data) ) ...

If there is another method that posts to the URL that the above code rests on (an Auth class trying to preserve the page the person was trying to reach, for example), then chances are good the method will think the user is trying to post to that method as well.

Anyway, my quick solution to ensure that only the data *I* want is posted is this:

if( !empty($this->data['ModelName']) ) { ..

This ensures that the method is only looking for the data that we want to post to it.
