Controller::set(), as you can see, adds a variable with the supplied
name & value to the $viewVars array which, in turn, is made available
to the View object. However, you're not creating a *local* variable
with the given name & value. For that, you'd need to first asign it to
a variable, then use set() to make it available to the View:
$foo = 'bar';
$this->set('foo', $foo);
If you need to set several vars for the view but need to use them in
the controller, you can do:
$foo = 'foo';
$bar = 'bar';
...
$this->set(compact('foo', 'bar'));
... which will do the same thing.
One other thing you should know about: Cake will screw with your
variable names if you're not careful. If there's an underscore in the
variable name and you use compact(), you have to take an extra measure
or Cake will create a camel-cased variable name (no, I don't
understand why). So, if you do:
$this->set(compact('foo_bar'));
... you'll end up with a $fooBar variable in the View instead of
$foo_bar. To avoid this, do:
$foo_bar = 'whatever';
$this->set(compact('foo_bar'), false);
