$this->loadModel('SubjectTutor');
$this->loadModel('Standard');
$this->loadModel('Province');
$this->loadModel('City');
$this->loadModel('School');
$this->loadModel('User');
$standard_data = $this->Standard->find('first',array('conditions'=>array('Standard.id'=>$standard_id)));
$province_id = 32;
$city_id = 44;
$school_id = 1855;
$this->set('title_for_layout','Subject');
if(!empty($this->request->data))
{
if (!isset($this->request->params['_Token']['key']) || ($this->request->params['_Token']['key'] != $this->request->params['_Token']['key']))
{
$blackHoleCallback = $this->Security->blackHoleCallback;
$this->$blackHoleCallback();
}
//validate user data
$this->SubjectTutor->set($this->request->data['SubjectTutor']);
$this->SubjectTutor->setValidation('add');
if ($this->SubjectTutor->validates())
{
// $this->request->data['Subject']['user_id'] = $this->Auth->user('id');
$userdata = $this->request->data['SubjectTutor'];
$this->SubjectTutor->save($userdata,false);
$subject_tutor_id = $this->SubjectTutor->id;
$this->SubjectTutor->school_id = 1855;
$this->SubjectTutor->province_id = 32;
$this->SubjectTutor->city_id = 44;
$this->SubjectTutor->state_private = 1;
$this->Session->setFlash("Record has been added successfully", 'admin_flash_good');
$this->redirect(array('controller'=>'standards', 'action'=>'subject_list',$standard_id));
}

{
$this->Session->setFlash("Record has not been created", 'admin_flash_bad');
}

$tutors = $this->User->getStandardTutorList($standard_id);
$subjects = $this->Subject->getStandardSubjectList($standard_id);
$standards = $this->Standard->getStandardList();
$provinces = $this->Province->getProvinceList();
$cities = $this->City->getCityList();

$this->set(compact('provinces'));
$this->set(compact('standards','standard_id','province_id','city_id','school_id','standard_data','tutors','subjects','provinces','cities','schools','tutor_id'));

Answer 1

When you use the 'disabled' option for a field in a view, that field doesn't get set when the form data is saved.. Either use 'readonly' option instead, or set those values in the controller before you save (since you don't need user input anyway). Or display the value to the user without pretending they have any input, and use hidden fields to pass the correct data.
