Add PHP function in CakePHP model array

Question

I have an array of behaviour $actas.Problem is when I adding date() function on the array string,it's return an error:

Example:

public $actas = array(
'Uploader.Attachment'=>array( 
      'books' => array(
            'maxWidth' => 1200,
            'maxHeight' => 1200,
            'extension' => array('pdf'),
            'nameCallback' => '',
            'append' => '',
            'prepend' => '',
            'tempDir' => TMP,
            'uploadDir' => '/var/www/html/apps/webroot/files/uploads/books' . date('d-m-Y'),//this  is where I want to add the function.
            'transportDir' => ''
            )
       )
   );

however it's not working. I also do like this:

 public $actas = array(
    'Uploader.Attachment'=>array( 
          'books' => array(
                'maxWidth' => 1200,
                'maxHeight' => 1200,
                'extension' => array('pdf'),
                'nameCallback' => '',
                'append' => '',
                'prepend' => '',
                'tempDir' => TMP,
                'uploadDir' => "/var/www/html/apps/webroot/files/uploads/books'".date('d-m-Y')."'",//this  is where I want to add the function.
                'transportDir' => ''
                )
           )
       );

also not worked.

So my question is how to do that? If I have a lot of mistaken,please tell me so I can learn more about the matter.

Thanks in advance.

ahh ok I was not looking at it with my OO hat on. you can't do this because:

Properties
Class member variables are called "properties". You may also see them referred to using other terms such as "attributes" or "fields", but for the purposes of this reference we will use "properties". They are defined by using one of the keywords public, protected, or private, followed by a normal variable declaration. This declaration may include an initialization, but this initialization must be a constant value--that is, it must be able to be evaluated at compile time and must not depend on run-time information in order to be evaluated.

you need to use the __construct() method
