How can you validate the number of "multiple" selected?
I have a Post which hasMany, and HABTM relations so saving with :
if ( $this->Post->saveAll( $this->data, array('validate' => 'only') ) )
{//only testing to get errors
but I never get any validation errors for the HABTM model
Category:
public $validate = array(
'Category' => array(
'multiple' => array(
'required' => false,
'allowEmpty' => true,
'rule' => array(
'multiple', array('max' => 3),
'message' => 'Please select one, two or
three options'))));
Post HABTM Category
Ideas?
Thanks
