Color
Zend\Form\Element\Color
is meant to be paired with
Zend\Form\View\Helper\FormColor
for HTML5 inputs with type "color".
This element adds filters and a Regex
validator to its input filter
specification in order to validate an HTML5 valid simple color
value on the server.
Basic Usage
This element automatically adds a type
attribute of value color
.
use Zend\Form\Element;
use Zend\Form\Form;
$color = new Element\Color('color');
$color->setLabel('Background color');
$form = new Form('my-form');
$form->add($color);
The following uses array notation instead:
use Zend\Form\Element;
use Zend\Form\Form;
$form = new Form('my-form');
$form->add([
'type' => Element\Color::class,
'name' => 'color',
'options' => [
'label' => 'Background color',
],
]);
