Week

Zend\Form\Element\Week is meant to be paired with the FormWeek helper for HTML5 inputs with type "week". This element adds filters and validators to its input filter specification in order to validate HTML5 week input values on the server.

Basic Usage

This element automatically adds a type attribute of value week.

use Zend\Form\Element;
use Zend\Form\Form;

$week = new Element\Week('week');
$week->setLabel('Week');
$week->setAttributes([
    'min'  => '2012-W01',
    'max'  => '2020-W01',
    'step' => '1', // weeks; default step interval is 1 week
]);

$form = new Form('my-form');
$form->add($week);

Using array notation:

use Zend\Form\Element;
use Zend\Form\Form;

$form = new Form('my-form');
$form->add([
    'type' => Element\Week::class,
    'name' => 'week',
    'options' => [
        'label' => 'Week',
    ],
    'attributes' => [
        'min' => '2012-W01',
        'max' => '2020-W01',
        'step' => '1', // weeks; default step interval is 1 week
    ],
]);

Set all attributes before calling prepare

The min, max, and step attributes should be set prior to calling Zend\Form::prepare(). Otherwise, the default input specification for the element may not contain the correct validation rules.

Public Methods

The following methods are specific to the Week element; all other methods inherited from the parent DateTime class are also available.

Method signature Description
getInputSpecification() : array Returns a input filter specification, which includes Zend\Filter\StringTrim and will add the appropriate validators based on the values from the min, max, and step attributes and format option. See the DateTime element for more information. One difference from Zend\Form\Element\DateTime is that the Zend\Validator\DateStep validator will expect the step attribute to use an interval of weeks (default is 1 week).
