Secure Validator is a library for input validation. It is based on [Sirius Validation](https://github.com/siriusphp/validation).

Requirements
------------

[](#requirements)

- PHP 5.4.0 or later

Features
--------

[](#features)

### Default Rules

[](#default-rules)

Secure Validator promotes strict validation. It sets default validation rules to all fields.

- `ValidUtf8` checks if value is valid UTF-8 character encoding
- `IsString` checks if value is string
- `NoControl` checks if value does not have control characters (except for tab and newline)

And

- adds `MaxLength` 1 letter

That is you have to set (overwrite) max length rule to all fields. You don't forget it.

If a field does not match the default rules, you can remove the rules.

```
$validator->remove('field', 'ValidUtf8');
```

### Fatal Rules

[](#fatal-rules)

You can set a validation rule as *fatal* to detect abnormal input like an attack.

```
$validator->add('field', 'maxlength', ['max' => 60, 'fatal' => true]);
```

If a fatal rule fails, exception `FatalValidationError` will be thrown immediately.

### Validated Data

[](#validated-data)

You can get validated data only with `$validator->getValidated()`.

How to Use
----------

[](#how-to-use)

See [example.php](example.php) and [Sirius Validation Documentation](http://www.sirius.ro/php/sirius/validation/).

```
$validator = new \Kenjis\Validation\Validator;
$validator->add('field', 'required | maxlength(max=60)');
if ($validator->validate($_POST)) {
    // validation passed
} else {
    // validation failed
}
```

See [Built-in validation rules](http://www.sirius.ro/php/sirius/validation/validation_rules.html).

### Added Method

[](#added-method)

#### `Validator::filter()`

[](#validatorfilter)

Add filtering rule of Sirius\\Filtration. See [Built-in filters](https://github.com/siriusphp/filtration/blob/master/docs/filters.md).

Validator will apply filters before validation.

```
$validator->filter('field', 'StringTrim');
```

#### `Validator::getValidated()`

[](#validatorgetvalidated)

Get validated values.

```
$allData = $validator->getValidated();

$field = $validator->getValidated('field');
```

#### `Validator::getInputValue()`

[](#validatorgetinputvalue)

Get input value after filtering of specific field.

```
$field = $validator->getInputValue('field');
```

### Tips

[](#tips)

When you set `required`, if a rule fails, Sirius Validation will not apply any more rules to that field.
