Because Listing is associated with User model, you should have a
user_id field in its table. So, you want Listing.user_id in the form
field.
echo $form->input('Listing.user_id', array('value' => $user['id']));
For an edit action, you'll already have user_id in your $data array,
so the input can just be:
echo $form->input('Listing.user_id');
It's good practice to use the model name in the calls to FormHelper.
It makes things a lot clearer.
