PHP ValidatorGroup
==================

[](#php-validatorgroup)

Validator group for validating form and json body data.

Usage
-----

[](#usage)

### Validation Group

[](#validation-group)

Create a class and extend `\District5\ValidatorGroup\Group`, adding fields to be validated against.

```
/**
 * Creates a new instance of AuthValidationGroup
 */
public function __construct()
{
    $stringTrim = new StringTrim();

    $this->addField('username', [new StringLength(['min' => 4, 'max' => 254])], [$stringTrim], true);
    $this->addField('password', [new StringLength(['min' => 6, 'max' => 64])], [$stringTrim], true);
    $this->addField('device_id', [new StringLength(['min' => 6, 'max' => 64])], [], true);
}
```

### Validating

[](#validating)

This can then be used in a route, with a handler, for example with the following code:

```
$request = $app->request();

$vg = new \Project\Validate\Group\AuthAuthValidationGroup();
```

The validation group can be used to validate against any custom data with the correct handler; the library as a default ships with a JSON handler:

```
$handler = new \District5\ValidatorGroup\Handler\JSON($request->getBody());
$valid = $vg->isValid($handler);
```

### Custom Handlers

[](#custom-handlers)

You can create your own handlers by implementing the `\District5\ValidationGroup\Handler\HandlerInterface` and passing this into the `ValidationGroup`.

### Errors

[](#errors)

If validation failed, the validation group will give you some hint as to why it failed by calling:

```
$vg->getLastErrorMessage();
```
