Zend框架2表单元素选择和原则2的结果 - Zend Framework 2 Form Element Select and result from Doctrine 2

Zend Framework 2 Form Element Select and result from Doctrine 2

我在 ZF2 中选择表单元素时遇到问题。我创建了查询原则 2 并具有良好的结果对象列表。

$langs = $this->getEntityManager()->getRepository('Application'Entity'Langs')->findAll();

并创建简单的表单：

class Coupon extends Form
{
    protected $objectManager;
    public function __construct($name = null)
    {        
        parent::__construct('coupon');
        $this->setAttribute('method', 'post');
        $this
             ->setAttribute('method', 'post')
             ->setHydrator(new ClassMethodsHydrator(false))
         ;
    $this->add(array(
            'name' => 'id',
            'attributes' => array(
                'type'  => 'hidden',
            ),
        ));
     }
   $this->add(array(
         'type' => 'Zend'Form'Element'Select',
         'name' => 'language',
         'attributes' => array(
             'class' => 'form-control',
         ),
         'options' => array(
                 'label' => 'default.form.message',
                 'empty_option'    => '--- choose formElementName ---',
                 'value_options' => array(
                         '0' => 'French',
                         '1' => 'English',
                         '2' => 'Japanese',
                         '3' => 'Chinese',
                 ),
         )
    ));
}

如何将结果（$langs）转换为数组以进行value_options - zend 元素选择？我应该为此使用什么？

我解决了它。

我创造

public function getFormElementConfig()
    {
        return array(
            'invokables' => array(
                'Coupon' => 'Application'Form'Langs',
            ),
            'initializers' => array(
                'ObjectManagerInitializer' => function ($element, $formElements) {
                    if ($element instanceof ObjectManagerAwareInterface) {
                        $services      = $formElements->getServiceLocator();
                        $entityManager = $services->get('Doctrine'ORM'EntityManager');
                        $element->setObjectManager($entityManager);
                    }
                },
            ),
        );

并在表单中添加初始化：

public function init()
    {
        parent::init();
        $this->add(
            array(
                'type' => 'DoctrineModule'Form'Element'ObjectSelect',
                'name' => 'messages',
                'options' => array(
                    'object_manager' => $this->getObjectManager(),
                    'target_class'   => 'Application'Entity'Langs',
                    'property'       => 'title',
                ),
            )
        );
    }

它适用于:)谢谢山姆。
