$var[0]['id'] is the correct syntax for the array you posted, are you
sure it is really the content of $var? Not rather $var['Post'][0]
['id']?
Btw, you shouldn't do the findByTitle twice, this is better:
$var = $this->Post->findByTitle($this->data['Post']['title']);
if (!empty($var))
{
$this->redirect('/posts/view/' . $var[0]['id']);
}
Hope this helps,
Michael
