Send email when you edit a field in Cakephp - cakephp

Question

I have employee application where users standing can be resigned, active, new and transferred. What i would like to achieve is that when the standing of an employee is changed/edited from active (standing_id = 1) it should be able to send through an email but its not. I have put a email function in the EmployeeController. Below is my code.
function _sendNewEmployeeEditMail($id) {
$Employee = $this->Employee->read(null,$id);
$email = new CakeEmail();
$email->from(array('no-reply#test.com' => 'Testing App'));
$email->to(array('jaahvicky#gmail.com' => 'Name Surname'));
$email->subject('New Employee');
$email->template('employee_email');
$email->viewVars(compact('Employee'));
$email->emailFormat('html');
$edit_email = true;
$current_status = $this->Employee->field('standing_id');
if($current_status==1) {
$edit_email = false;
if ($email->send()) {
$this->Session->setFlash('Your employee has been submitted.','default',array('class' => 'notification'));
return true;
} else {
$this->Session->setFlash('Your employee has not been submitted.','default',array('class' => 'error'));
return false;
}
}
}
and in my edit save function here is how i am trying to send the email
public function edit($id = null) {
$this->Employee->id = $id;
if (!$this->Employee->exists()) {
throw new NotFoundException(__('Invalid employee'));
}
if ($this->request->is('post') || $this->request->is('put')) {
if ($this->Employee->save($this->request->data)) {
$this->Session->setFlash(__('The employee has been saved'),'default',array('class' => 'notification'));
$this->_sendNewEmployeeEditMail($this->Employee->getLastInsertID() );
$this->redirect(array('action' => 'index'));
} else {
$this->Session->setFlash(__('The employee could not be saved. Please, try again.'),'default',array('class' => 'error'));
}
} else {
$this->request->data = $this->Employee->read(null, $id);
}
$standings = $this->Employee->Standing->find('list');
$this->set(compact('standings'));

Answer 1

You're using $this->Employee->getLastInsertID(), which will only be present after inserting a new Employee.
Because you're editing an existing Employee, this will always be empty. You should use the $id in stead;
$this->_sendNewEmployeeEditMail($id);
