Re: save data problem

I hope this help you

public function save($data = null, $validate = true, $fieldList =
array()) {
$return = false;
if (isset($data['Usercat']['subcat_id']) && is_array($data['Usercat']
['subcat_id'])) {
foreach ($data['Usercat']['subcat_id'] as $subcat) {
$saveData = array(
'user_id' => $data['Usercat']['user_id'],
'subcat_id' => $subcat,
);
$this->create();
$return = parent::save($saveData); // here can add some tests ...
}
}
return $return;
}
