You should save each separately. Set up your association as HABTM.
Event model:
public $hasAndBelongsToMany = array(
'Tag' => array(
'className' => 'Tag',
'joinTable' => 'events_tags',
'foreignKey' => 'event_id',
'associationForeignKey'=> 'tag_id'
)
);
Tag model:
public $hasAndBelongsToMany = array(
'Post' => array(
'className' => 'Event',
'joinTable' => 'events_tags',
'foreignKey' => 'tag_id',
'associationForeignKey'=> 'event_id'
)
);
In your controller action:
$this->set('tags', $this->Event->Tag->find('list'));
In your view:
echo $form->label('Tag', 'Tag(s)', array('class' => 'Required'));
echo $form->error('Tag', 'Please choose at least one tag.');
echo $form->select('Tag', $tags, null, array('class' => 'Required',
'multiple' => 'checkbox'));
back in the controller action:
/* ensure that at least one Tag was chosen
*/
$this->Event->Tag->set($this->data);
if (!$this->Event->Tag->validates())
{
$this->Event->Tag->invalidate('Tag');
}
else if ($this->Event->save($this->data))
