In your controller you first set the error message when you want it to display
if(sizeof($this->$mainModelName->validationErrors) > 0){
$this->Session->setFlash('Please fill in all compulsory fields and rectify errors');
}
Then you just call the flash function in the class "Session" in your view or layout and put it inside the element you want it to display
<div class="form-error" align="center"><?php $session->flash();?></div>
