Your data structure for saving should look like this:
array
(
[User] => array
(
[id] => 999
)
[Friend] => array
(
[id] => 888
)
)
so do this:
[code]
if (!empty($this->data)) {
$this->data['User']['id'] = $this->Auth->user('id');
if ( $this->User->save( $this->data ) ) {
...
[/code]
and change your view accordingly!
That should be the correct way for saving the HABTM data that you
have.
Enjoy,
John
