#Sirius Validation

Sirius Validation is a library for data validation. It offers:

1. validator object
2. 45 build-in validation rules. There are validators for strings, array, numbers, emails, URLs, files and uploads
3. validation helper to simplify the validation of single values

Out-of-the-box, the library can handle arrays, ArrayObjects and objects that have implemented the toArray method. In order to validate other data containers you must create a DataWrapper so that the validator be able to extract data from your object.

##Elevator pitch

$validator = new \Sirius\Validation\Validator;

// add a validation rule
$validator->add('title', 'required');

// add a rule that has a list of options
$validator->add('title', 'length', array('min' => 10, 'max' => 100));
// or use JSON
$validator->add('title', 'length', '{"min": 10, "max": 100}');
// or a URL query string
$validator->add('title', 'length', 'min=10&max=100');
// or, if you know that the validator can CORECTLY parse (ie: understand) the options string
$validator->add('title', 'length', '10,100');

// add a rule with a custom error message
$validator->add('title', 'maxlength', 'max=100', 'Article title must have less than {max} characters');

// add a rule with a custom message and a label (very handy with forms)
$validator->add('title:Title', 'maxlength', 'max=100', '{label} must have less than {max} characters');

// add all of rule's configuration in a string (you'll see later why it's handy')
$validator->add('title:Title', 'maxlength(max=255)({label} must have less than {max} characters)');

// add multiple rules at once (separate using [space][pipe][space])
$validator->add('title:Title', 'required | maxlength(255) | minlength(min=10)');

// add all your rules at once
$validator->add(array(
    'title:Title' => 'required | maxlength(100)({label} must have less than {max} characters)',
	'content:Content' => 'required',
	'source:Source' => 'website'
));

// add nested rules
$validator->add('recipients[*]:Recipients', 'email'); //all recipients must be valid email addresses
$validator->add('shipping_address[city]:City', 'MyApp\Validator\City'); // uses a custom validator to validate the shipping city

##Known issues

In PHP 5.3 there is some problem with the SplObject storage that prevents the library to remove validation rules. This means that in PHP 5.3, you cannot remove a validation rule from a Validator or ValueValidator object
