What I usually do for my forms is to put them in an element. So, for
Post model, I'd have in views/posts/add.ctp a line with
$this->element('posts/form'). And the file
views/elements/posts/form.ctp includes all of the logic for creating
the form, including whether to show an add or edit form, stuff for
admins only, etc.

switch ($this->params['action'])
{
case 'edit':
echo $form->create('Post', array('action' => 'edit'));
echo $form->hidden('Post.id');
echo $form->hidden('Post.user_id');
break;

case 'add':
default:
echo $form->create('Post', array('action' => 'add'));
echo $form->hidden('Post.user_id', array('value' => $user_id));
}

This way, you can include the form in your add or edit views, as well
as in your index view. Put a debug($this->params) in your view
somewhere to get an idea how that's set up.
