Email validation is an important part of any application and especially, when we use email as username in our application and you want to make sure that user enter a valid and unique email address.
In CakePHP application we can define email validation rule in the Model like below:
<?php
class User extends AppModel {
public $validate = array(
'email' => array(
'mustNotEmpty' => array(
'rule' => 'notEmpty',
'message' => 'Please enter a email.',
'last' => true
) ,
'mustBeEmail' => array(
'rule' => array(
'email'
) ,
'message' => 'Please enter a valid email',
'last' => true
) ,
'mustUnique' => array(
'rule' => 'isUnique',
'message' => 'This email is already exists.',
)
) ,
);
}
?>
