(also, if can understand it's suppose do, please feel free guide me perhaps better code :) new cake:

 public function index() {          if($this->request->is("post")) {             $aid = $this->request->data['asset']['asset_identifier'];             $type = $this->request->data['asset']['asset_type_id'];             $asset = $this->asset->find("first",array("fields" => array("asset.id", "asset.user_id", "asset.status_id", "asset.financial_id", "asset.insurance_id"),"conditions" => array("asset.asset_identifier" => $aid, "asset.asset_type_id" => $type)));             if($asset != false) {                 $uid = $this->auth->user("id");                 // update, depends on info:                 $this->asset->id = $asset['asset']['id'];                 foreach(array("financial_id", "insurance_id", "user_id") $value) {                     if($asset['asset'][$value] != 0) {                         $emails[] = $asset['asset'][$value];                     }                 }                 if(isset($emails) && count($emails)) {                     $this->request->data['asset']['status_id'] = 1;                     $email = new cakeemail();                     $email->from(array('noreply@assetchase.co.za' => 'assetchase.co.za'));                     $email->subject('assetchase.co.za result notification.');                     foreach($emails $value) {                         $user = $this->user->find("first",array("fields" => array("username"),"conditions" => array("id" => $value)));                         $email->to($user['user']['username']);                         $email->send('a new notification, booyah!');                         // send email username.                     }                 }                 if($this->auth->user("user_type_id") == 2) {                     $this->request->data['asset']['user_id'] = $uid;                 } elseif($this->auth->user("user_type_id") == 3) {                     $this->request->data['asset']['financial_id'] = $uid;                 } elseif($this->auth->user("user_type_id") == 4) {                     $this->request->data['asset']['insurance_id'] = $uid;                 }             }             $this->asset->id = 62;             if($this->asset->saveall($this->request->data)) {                 $this->session->setflash("a new asset has been loaded",'success');                 $this->redirect(array("controller" => "asset", "action" => "thankyou", "guest"));             } else {                 $this->session->setflash('an error has occured.','default',array('class'=>'error'));             }         }         $assettypes = $this->asset->assettype->find('list');         $this->set("assettypes", $assettypes);      }

when call $this->asset->saveall($this->request->data) telling cake take post data , try save it. not @ $this->asset set id 62 @ all. can verify inspecting output of var_dump($this->request->data). try $this->request->data['asset']['id'] = 62 instead.
