Answer 1

Finally i got the answer to my question. i.e
User.php
<?php
class User extends AppModel
{
public $validate= array(
'username'=>array(
'rule'=>'notEmpty',
'required'=>false,
'message'=>'Enter your name'
),
'email' => array(
'rule' => 'notEmpty',
'required'=>false,
'message' => 'Please enter your email'
)
);
}
?>
UsersController.php
<?php
class UsersController extends AppController {
public $helpers = array('Html', 'Form');
public function register() {
$this->User->create();
if ($this->User->save($this->request->data)) {
$this->redirect(array('controller'=>'users', 'action'=>'welcome'));
}
else{
echo"register fail";
}
}
public function welcome(){
$this->flash('register successfully','/users/register');
}
}
?>
register.ctp
<?php
echo $this->Form->create('User');
echo $this->Form->input('username',array('required'=>'false'));
echo $this->Form->input('email',array('required'=>'false'));
echo $this->Form->end('Register');
?>
this is the correct answer for above asking question.The main mistake done in my above question was i am given required'=>'true.',now given required'=>'false.' in register.ctp class.now problem resolved.

You need to change you register action in user controller like this:
public function register() {
$this->User->create();
if ($this->User->save($this->request->data)) { //this way it automatically save or show error message if there is one
$this->flash('register success');
}
else{
$this->flash('register fail');
}
}
Hope it helps.

Answer 3

Try this:
add a helper
var $helpers = 'session';
then add the flash message as
$this->Session->setFlash(__('error'));

Answer 4

What you actually want is to show the validation errors, so instead of
$this->flash('register fail');
Do
$this->Session->setflash($this->User->validationErrors);
$this->redirect('/users/register');
