From cakePHP 2.0 documentation:

You can validate that a set of fields are unique by providing multiple fields and set $or to false:

public $validate = array(
    'email' => array(
        'rule' => array('isUnique', array('email', 'username'), false),
        'message' => 'This username & email combination has already been used.'
    )
);

Make sure to include the original field in the list of fields when making a unique rule across multiple fields.

If a listed field isn’t included in the model data, then it’s treated as a null value. You may consider marking the listed fields as required.
