TL;DR An validation tool for arrays filled by foreign input like forms, json data, query parameters etc. The name is from Old Norse language and means defender.


The usual way...

composer require tflori/verja


Initialize a container, set the input data, define filters and validators, validate the data, get the data.

$gate = new Verja\Gate();
    'username' => ['notEmpty', 'strLen:3:20'],
    'password' => ['notEmpty', 'strLen:8'],
    'email' => ['notEmpty', 'email'],

if ($gate->validate($_POST)) {
  // how ever your orm works..
  $user = new User($gate->getData());
} else {
  $errors = $gate->getErrors();

If you prefer auto completion you can of course pass objects:

use Verja\Validator;

    'username' => (new Field())
        ->addValidator(new Validator\NotEmpty())
        ->addValidator(new Validator\StrLen(3, 20)),
    'password' => [new Validator\NotEmpty(), new Validator\StrLen(8)],
    'email' => ['notEmpty', new App\Validator\DomainEmail('')]
