How to use

Enable the plugin in your target model:

class User extends AppModel {

    public $actsAs = array(
        'MultiValidation.MultiValidation' => array(
            'types' => array(
                'enforceUsernameAndEmail' => array(
                    'username' => array(
                        'onlyAlpha' => array(
                            'rule' => 'alphaNumeric'
                        ),
                    ),
                    'email' =>
                        'validEmail' => array(
                            'rule' => 'email',
                            'required' => true
                        ),
                    )
                ),
                'enforcePassword' => array(
                    'password' => array(
                        'minCharsAllowed' => array(
                            'rule' => array('minLength', 8)
                        ),
                    ),
                ),
            )
        )
    )

    public $validate = array(
        'username' => array(
            'mustNotBeBlank' => array(
                'rule' => 'notEmpty'
            )
        ),
        'password' => array(
            'minCharsAllowed' => array(
                'rule' => array('minLength', 4)
            )
        ),
    );
}

Then in your model or controller you can do the following actions:

    // Add new username and email validation:
    $User->addValidation('enforceUsernameAndEmail');
    // $User->loadedValidation() would return array('enforceUsernameAndEmail')

    // Reset to default state:
    $User->resetValidation();
    // $User->loadedValidation() would return array('_default')

    // Load and set only the password validation:
    $User->loadValidation('enforcePassword');
    // $User->loadedValidation() would return array('enforcePassword')

    // Add the other validation type also:
    $User->addValidation('enforceUsernameAndEmail');
    // $User->loadedValidation() would return array('enforcePassword', 'enforceUsernameAndEmail')

    // Reset again to default state:
    $User->resetValidation();
    // $User->loadedValidation() would return array('_default')
