Server side validation not rendering in page in php
===

I am new to PHP. I have a form and applying client side and server side validations on it.

But when i apply client side validations and say it passes but server side validation failes then also its not showing server side validation.

Actually i could see in firebug that it goes to the condition where server side validaion fails:

if $this->UserEntry->validates()) {
            	
                $this->UserEntry->addUser($this->data['UserEntry'], $fbme);
                //set flash to user screen
                $this->Session->setFlash('User was added.');
                //redirect to user list
                $this->redirect(array('action' => 'thanks'));
            } else {
            	//if save failed
                $this->Session->setFlash('Unable to add user. Please, try again.');
            }


I could c msg 'Unable to add user. Please, try again.' in firebug but in page its not rendering.

Can you please what could be the reason

Thanks
