.. _zend.form.element.date:
Date
^^^^
``Zend\Form\Element\Date`` is meant to be paired with the ``Zend\Form\View\Helper\FormDate`` for `HTML5 inputs with type
date`_. This element adds filters and validators to it's input filter specification in order to validate HTML5 date
input values on the server.
.. _zend.form.element.date.usage:
.. rubric:: Basic Usage
This element automatically adds a ``"type"`` attribute of value ``"date"``.
.. code-block:: php
:linenos:
use Zend\Form\Element;
use Zend\Form\Form;
$date = new Element\Date('appointment-date');
$date
->setLabel('Appointment Date')
->setAttributes(array(
'min' => '2012-01-01',
'max' => '2020-01-01',
'step' => '1', // days; default step interval is 1 day
))
->setOptions(array(
'format' => 'Y-m-d'
));
$form = new Form('my-form');
$form->add($date);
Here is with the array notation:
.. code-block:: php
:linenos:
use Zend\Form\Form;
$form = new Form('my-form');
$form->add(array(
'type' => 'Zend\Form\Element\Date',
'name' => 'appointment-date',
'options' => array(
'label' => 'Appointment Date',
'format' => 'Y-m-d'
),
'attributes' => array(
'min' => '2012-01-01',
'max' => '2020-01-01',
'step' => '1', // days; default step interval is 1 day
)
));
.. note::
Note: 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.
.. _zend.form.element.date.methods:
.. rubric:: Public Methods
The following methods are in addition to the inherited :ref:`methods of Zend\\Form\\Element\\DateTime
<zend.form.element.date-time.methods>`.
.. function:: getInputSpecification()
:noindex:
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
:ref:`getInputSpecification in Zend\\Form\\Element\\DateTime
<zend.form.element.date-time.methods.get-input-specification>` 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 days (default is 1 day).
