Re: How to set the incoming $id to be the last post entered

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));
}

Hi

I'm on CakePHP 1.3

I have an action in my posts_controller.php that gets a list of latest posts and the data for a particular post if the $id is set...

function mypage($id = null) {
        $this->Post->recursive = 0;
        $this->set('posts', $this->paginate());
        $this->set('mainpost', $this->Post->read(null, $id));
}

I then use this to display a column or recent posts and the main post if an $id is supplied.

What I would like to do is set the incoming $id to be the last post entered if a specific $id isn't already set in the URL. ie: run this code if $id is null...

        $id = $this->Post->find('first', array('order' => array('Post.id DESC')));

But I'm not sure how to combine these two bits of code together in one function. Assuming that 's the right way to go about what I'm trying to achieve?
