Re: save data problem

i have this array and user can choice many subcat:

Array
(
[Usercat] => Array
(
[subcat_id] => Array
(
[0] => 3
[1] => 1
)

[user_id] => 7
)

)

you say i can use this:

function save($data = null, $validate = true, $fieldList = array()) {
put your code here <=what code?
then

return parrent:: save($data, $validate, $fieldList) ; <= where?
or
put parrent:: save(..) into a cycle depending what you want to do.

}

but can you explain more about save function,i think you need more
information about my problem

i have 2 table: 1.subcats 2.usercats this is sql:

CREATE TABLE IF NOT EXISTS `subcats` (
`id` int(11) unsigned NOT NULL AUTO_INCREMENT,
`cat_id` int(11) NOT NULL,
`title` varchar(255) COLLATE utf8_persian_ci NOT NULL,
`status` int(2) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_persian_ci
AUTO_INCREMENT=4 ;

--
-- Dumping data for table `subcats`
--

INSERT INTO `subcats` (`id`, `cat_id`, `title`, `status`) VALUES
(1, 2, 'sub2-1', 0),
(2, 2, 'sub2-2', 0),
(3, 1, 'sub1-1', 0);

-- --------------------------------------------------------

--
-- Table structure for table `usercats`
--

CREATE TABLE IF NOT EXISTS `usercats` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`user_id` int(11) NOT NULL,
`subcat_id` int(11) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_persian_ci
AUTO_INCREMENT=11 ;

INSERT INTO `usercats` (`id`, `user_id`, `subcat_id`) VALUES
(3, 1, 1),
(4, 6, 2),

and my model:
subcat:
var $hasMany = array(
'Usercat' => array(
'className' => 'Usercat',
'foreignKey' => 'subcat_id',
'dependent' => false,
'conditions' => '',
'fields' => '',
'order' => '',
'limit' => '',
'offset' => '',
'exclusive' => '',
'finderQuery' => '',
'counterQuery' => ''
)
);

and usercat:

var $belongsTo = array(
'Subcat' => array(
'className' => 'Subcat',
'foreignKey' => 'subcat_id',
'conditions' => '',
'fields' => '',
'order' => ''
)
);

and in my UsercatsController:

function add() {
if (!empty($this->data)) {
$this->Usercat->create();
if ($this->Usercat->save($this->data)) {
$this->Session->setFlash(__('yes', true));
$this->redirect(array('action' => 'index'));
} else {
$this->Session->setFlash(__('no', true));
}
}else {
$this->Session->setFlash(__('no', true));
$this->redirect(array('controller' => 'Subcats','action' =>
'usercat'));

}
}
