Answer 1

First of all define validate function in model
public $validate = array(
'username' => array(
'nonEmpty' => array('rule' => array('notEmpty'),
'message' => 'A username is required',
'allowEmpty' => false),),
'password' => array(
'required' => array(
'rule' => array('notEmpty'),
'message' => 'A password is required' ),
'min_length' => array(
'rule' => array('minLength', '6'),
'message' => 'Password must have a mimimum of 6 characters')),
'password_confirm' => array(
'required' => array(
'rule' => array('notEmpty'),
'message' => 'Please confirm your password' ), ),
'email' => array(
'required' => array(
'rule' => array('email', true),
'message' => 'Please provide a valid email address.' ),
),
);
Then in controller use
function register() {
if( isset($this->data) )
{
$this->User->create();
if($this->User->save($this->data))
{
$this->Session->setFlash( 'Thank you for registering!' );
}else
{
$this->Session->setFlash('An error occurred, try again!');
}
}
}
function login(){
if ($this->request->is('post')) {
$this->User->set($this->request->data);
if ($this->User->validates()) {
echo "This is valid!";
} else {
echo "This is invalid";
$errors = $this->User->validationErrors;
}
}
}
Registration ctp
<div class="users form">
<?php echo $this->Form->create('User');?>
<fieldset>
<legend><?php echo __('Add User'); ?></legend>
<?php echo $this->Form->input('username');
echo $this->Form->input('email');
echo $this->Form->input('password');
echo $this->Form->input('password_confirm', array('label' => 'Confirm Password *', 'maxLength' => 255, 'title' => 'Confirm password', 'type'=>'password'));
echo $this->Form->submit('Add User', array('class' => 'form-submit', 'title' => 'Click here to add the user') ); ?>
</fieldset>
<?php echo $this->Form->end(); ?>
</div>
login.ctp
<div class="users form">
<?php echo $this->Form->create('User');?>
<fieldset>
<legend><?php echo __('Add User'); ?></legend>
<?php echo $this->Form->input('email');
echo $this->Form->input('password');
echo $this->Form->submit('Login'); ?>
</fieldset>
<?php echo $this->Form->end(); ?>
</div>
