This post explains about CakePHP data validation in model. We will write validations in client-side, this explains about validations in server-side in CakePHP MVC framework.
CakePHP data validation in model by Anil Kumar Panigrahi
MySql Table:
CREATE TABLE IF NOT EXISTS `users` (
`userId` int(11) NOT NULL AUTO_INCREMENT,
`first_name` varchar(255) NOT NULL,
`last_name` varchar(255) NOT NULL,
`name` varchar(255) NOT NULL,
`email` varchar(255) NOT NULL,
`password` varchar(255) NOT NULL,
`userStatus` tinyint(4) NOT NULL DEFAULT '1',
PRIMARY KEY (`userId`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

Code of CakePHP Model
Path : /CakePHP/app/model/User.php
class User extends AppModel {
public $validate = array(

function system_check_email(){

// Write code for check the given email address is exists in DB or not

}
we can write your validation methods in your model itself.
In the view:
path: /CakePHP/app/View/Users/index.php
<?php echo $this->Form->input('User.first_name', array('tabindex' => '1', 'type' => 'text', 'placeholder' => 'First Name*', 'class' => 'text required input', 'id' => 'first_name', 'label' => false, 'maxlength' => '50', 'error' => array('attributes' => array('wrap' => 'div', 'class' => 'form-error')))); if(!$this->Form->isFieldError('User.first_name')) echo '<div class="invalid"></div>'; ?>
This is sample code, we can write all fields in the view.
