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

Well that's exactly what I thought (and had actually tried) but when I
added that I got an error message appearing at the top of my view if I
visit the URL without an id...

Then it struck me that $id = $this->Post->find('first', array('order'
=> array('Post.id DESC'))); is returning an array not just the id!

I changed my 'if' to be...

if (empty($id)) {
$latestid = $this->Post->find('first', array('order' =>
array('Post.id DESC')));
$id = $latestid['Post']['id'];
}

...and now it works.

Cheers for the help
