I would think to just put it in an "if" construct and execute the statement
if the expression evaluates to true, no?
function mypage($id = null) {
if (empty($id)){
$id = $this->Post->find('first', array('order' => array('Post.id
DESC')));
}
$this->Post->recursive = 0;
$this->set('posts', $this->paginate());
$this->set('mainpost', $this->Post->read(null, $id));
}
