data in validation set

If you have to 'manually' put the data into the validationset, it's kind of useless isn't it? The validationset and the data should be separate. Something like this:

$v = new Validator;
$v->add('username', new Validate_Unique('Username must be unique!'));
$v->add('password', new Validate_NotEmpty('Please enter a password...'))
$v->add('position', function($v) {
return rand(0, 1) ? 'This is not a valid function!!' : true;
});
etc

or like

$v->add(array(
'username' => new Validate_...,
'password' => new Validate_...,
'position' => function($v) { }
));

and then to validate:

$v->validate($_POST);
or
$v->validate($this->data);
if you use a framework.


PS. I've only seen the example file (by far the most important always), not the actual class.

If you use it like that, you can extend the generic validation class to specific forms, eg. NewUserValidator, and put the entire validationset inside the class. Using is than possible in only a few lines:

$v = new NewUserValidator;
$v->validate($_POST);

The validation rules are inside the constructor/init of the NewUserValidator class.
