Elements

Select

Zend\Form\Element\Select is meant to be paired with FormSelect for HTML inputs with type "select". This element adds an InArray validator to its input filter specification in order to validate on the server if the selected value belongs to the values. This element can be used as a multi-select element by adding the multiple HTML attribute to the element.

Basic Usage

This element automatically adds a type attribute of value select.

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

$select = new Element\Select('language');
$select->setLabel('Which is your mother tongue?');
$select->setValueOptions([
    '0' => 'French',
    '1' => 'English',
    '2' => 'Japanese',
    '3' => 'Chinese',
]);

$form = new Form('language');
$form->add($select);

Using array notation:

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

$form = new Form('my-form');
$form->add([
    'type' => Element\Select::class,
    'name' => 'language',
    'options' => [
        'label' => 'Which is your mother tongue?',
        'value_options' => [
            '0' => 'French',
            '1' => 'English',
            '2' => 'Japanese',
            '3' => 'Chinese',
        ],
    ],
]);

You can add an empty option (option with no value) using the empty_option option:

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

$form = new Form('my-form');
$form->add([
    'type' => Element\Select::class,
    'name' => 'language',
    'options' => [
        'label' => 'Which is your mother tongue?',
        'empty_option' => 'Please choose your language',
        'value_options' => [
            '0' => 'French',
            '1' => 'English',
            '2' => 'Japanese',
            '3' => 'Chinese',
        ],
    ],
]);

Option groups are also supported by adding an options key to the value options:

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

$select = new Element\Select('language');
$select->setLabel('Which is your mother tongue?');
$select->setValueOptions([
     'european' => [
        'label' => 'European languages',
        'options' => [
           '0' => 'French',
           '1' => 'Italian',
        ],
     ],
     'asian' => [
        'label' => 'Asian languages',
        'options' => [
           '2' => 'Japanese',
           '3' => 'Chinese',
        ],
     ],
]);

$form = new Form('language');
$form->add($select);

Attributes on the options are supported by providing the options as a specification array instead of key-value pairs:

$select->setValueOptions([
    [
        'value' => '0',
        'label' => 'French',
        'attributes' => [
            'data-locale' = 'fr'
        ],
    ],
    [
        'value' => '1',
        'label' => 'Italian',
        'disabled' => true,
    ],
]);
