  1. when you want to save your data you will need to assign the validation. true activates the validation. how ever in default validation is set to true.

    $this->User->save($this->data)
//to 
$this->User->save($this->data , true ) //or false - set the validation here

// your function needs to be public    
public function register(){
   if(!empty($this->request->data)){        
      if($this->User->save($this->request->data)){
            //save data
        else{
            //data didn't save
        }
    }

}

  2. In some cases like create or update you need to set where you want to assign your validation behavior. e.g. on save on create or update.

  3. In your model 'required'=>true, is used for other reason. Use 'rule'=>'notEmpty', is for the inputs that is required

  4. Your Form it's not standard for cakephp validation: Create your Form and inputs cakephp based so you will have clear code and make the job available for your validation

    <?php echo $this->Form->create('User', array('url' => array('controller' => 'users', 'action' => 'register')));?>
        <fieldset>
                <legend><?php echo __('Register User'); ?></legend>
                <div class="seven columns">
        <?php
                echo $this->Form->input('username');    
                echo $this->Form->input('password');    
                echo $this->Form->input('first_name');
                echo $this->Form->input('last_name');
                echo $this->Form->input('phone_number');
                echo $this->Form->input('email');
                echo $this->Form->input('address1');
                echo $this->Form->input('address2');
        ?>
                </div>

        </fieldset>
    </div>

<?php echo $this->Form->end(__('Register'));?>

  5. remove var $name = 'Users'; => this line is already set in default

  6. Model: variables should be public 

    var $name='User';        
var $validate= array(); 

//change them to 

 public $name='User';        
 public $validate= array();

in your code you haven't written any code for data save.....if you will save or edit data..your model will take care of validation automatically as you have written var $validate
in your model code..........

create an action named register() and created a view register.ctp. Your register aciton code looks like that-

function register(){
    if(!empty($this->data)){
        $this->User->create();
        if($this->User->save($this->data)){
                 $this->Session->setFlash("User saved!");
                $this->redirect('/login');
            }
            else{
                 $this->Session->setFlash("Unable to save now, Try later!");
            }
        }
 }

Now when you try to save data, your data will validate automatically if you define validate rules on model.
