Via Composer:

$ composer require nepada/birth-number-input

Option A: install form container extension method via DI extension

    - Nepada\Bridges\BirthNumberInputDI\BirthNumberInputExtension

It will register extension method addBirthNumber($name, $label = null): BirthNumberInput to Nette\Forms\Container.

Option B: use trait in your base form/container class

You can also use BirthNumberInputMixin trait in your base form/container class to add method addBirthNumber($name, $label = null): BirthNumberInput.


trait FormControls

    use Nepada\Bridges\BirthNumberInputForms\BirthNumberInputMixin;

    public function addContainer($name)
        $control = new Container;
        if ($this->currentGroup !== null) {
        return $this[$name] = $control;


class Container extends Nette\Forms\Container

    use FormControls;


class Form extends Nette\Forms\Form

    use FormControls;



BirthNumberInput is form control that uses birth number value object to represent its value (see nepada/birth-number for further details). It automatically validates the user input and getValue() method always returns BirthNumber instance, or null if the input is not filled.

$birthNumberInput = $form->addBirthNumber('birthNumber');
$birthNumberInput->setValue('invalid'); // \InvalidArgumentException is thrown
$birthNumberInput->setValue('000101 / 0009'); // the value is internally converted to BirthNumber value object
$birthNumberInput->getValue(); // BirthNumber instance for 000101/0009

Client side validation

Using precompiled bundle

Using precompiled bundles is the quick'n'dirty way of getting client side validation to work.

<script src=""></script>
<script src=""></script>

Building your own bundle

It is highly recommended to install the client side package via nmp and compile your own bundle.

Here is an example script for initialization of birth number input and Nette forms.

import Nette from 'nette-forms';
import initializeBirthNumberInput from '@nepada/birth-number-input';
