CakePHP: How can I read in controller the string value of a flash message if set?

I need to know this so I can append messages (flashes) if needed.

This way I can give the user the full feedback and avoid one flash being overwritten (in a redirect, for ex, where the last controller, usualy, can do that).

I read the documentation and I did't find any option to be given in setFlash() in order to require this appending.

I know there is a Session::read(), but I do not know what key to search for..

Thank you!

The flash message could be retrieved by using this :

$message = $this->Session->read('Message.flash.message');
echo $message;

What you are looking for is:

$this->Session->read('Message');

Message is the key that hold the session messages for the current user, be it flash messages or auth messages. A simple pr($this->Session->read()) will give you output similar to:

Array(
    ['Auth'] => array(
        ... your auth keys and values here
    ),
    ['Message'] => array(
        ['flash'] => ... your current flash message array (if any)
        ['auth'] => ... your current auth message array (if any)
    )
)

Although I am not sure why you are worried. When you do 

$this->Session->setFlash('your message');
$this->redirect('/');

Even if you do have a redirect, the session message will persist and will display on the redirected page. You just need to make sure you are outputting the flash messages.
