如何使用 serviceLocator 将 ZF2 中的数据从 Controller 传递到 Form

Question

我需要将数据从控制器传递到字段集，如果我使用 serviceLocator 和 FactoryInterface 来获取我的表单，我该怎么做？有可能吗？

目前我的文件如下所示：

控制器

$eventID    = $id;
$matuserID  = $this->zfcUserAuthentication()->getIdentity()->getId();

// DATA I would like to pass to the form
$dataDB     = array('eventid' => $eventID, 'matuserid' => $matuserID); 
// Get Form
$form     = $this->getServiceLocator()->get('mat_multimail_createform');

创建表单工厂

public function createService(ServiceLocatorInterface $sm)
{ 
    $multimailFieldset = $sm->get('mat_multimail_fieldset');

    $form = new MultiMailCreateForm($multimailFieldset);
    // Set the hydrator
    $form->setHydrator(new DoctrineHydrator($sm->get('Doctrine\ORM\EntityManager')));

    return $form;
}

创建表单

public function __construct(FieldsetInterface $multimailFieldset)
{
    parent::__construct('create-multimail');

    //set the base fieldset
    $multimailFieldset->setUseAsBaseFieldset(true);
    $this->add($multimailFieldset);

    $this->add(array(
        'name'       => 'submit',
        'attributes' => array(
            'type'  => 'submit',
            'value' => 'Speichern',
            'class' => 'btn btn-primary',
            'id'    => 'submultimail'
        )
    ));
}

创建字段集工厂

public function createService(ServiceLocatorInterface $sm)
{
    $om = $sm->get('Doctrine\ORM\EntityManager');

    $form = new MultiMailFieldset($om, $options);
    // Set the hydrator
    $form->setHydrator(new DoctrineHydrator($om));
    $form->setObject(new Event());

    return $form;
}

字段集

public function __construct(ObjectManager $om, $options = array())
{
    parent::__construct('multimail');

    $this->add(array(
        'type' => 'Zend\Form\Element\Hidden',
        'name' => 'id'
    ));

    $this->add(array(
        'type' => 'Zend\Form\Element\Hidden',
        'name' => 'eventid'
    ));

    $this->add(array(
        'type'    => 'DoctrineModule\Form\Element\ObjectSelect',
        'name'    => 'extadressen',
        'attributes' => array(
            'class'     => 'form-control',
            'id'        => 'singleExtSel',
            'multiple'  => 'multiple',
        ),
        'options' => array(
            'object_manager' => $om,
            'target_class'   => 'Mat\Entity\AdressenExt',
            'property'       => 'email',
            'is_method'      => true,
            'find_method'    => array(
                'name'   => 'getExtAdressen',
                'params' => array(
                    'criteria' => array('userid' => $options['matuserid'], 'eventid' => $options['eventid']),
                ),
            ),
        ),
    ));

或者我是否必须将控制器更改为这样的：

    $options = array('eventid' => 1, 'matuserid' => 2);

    $form = new MultiMailFieldset($om, $options);
    // Set the hydrator
    $form->setHydrator(new DoctrineHydrator($om));
    $form->setObject(new Event());

谢谢！

好的，我想通了，感谢这篇文章ZF2 Get params in factory！ 我在工厂中获取参数并将它们传递给字段集：

字段集工厂

public function createService(ServiceLocatorInterface $sm)
{
    $om = $sm->get('Doctrine\ORM\EntityManager');

    // add user id
    $authUser   = $sm->get('zfcuser_auth_service');
    $authUserId = $authUser->getIdentity()->getId();

    // add current eventID to fetch addresses
    $router      = $sm->get('router');
    $request     = $sm->get('request');
    $routerMatch = $router->match($request);

    $eventID = $routerMatch->getParam("id");

    $options = array('userid' => $authUserId, 'eventid' => $eventID);

    $form = new MultiMailFieldset($om, $options);
    // Set the hydrator
    $form->setHydrator(new DoctrineHydrator($om));
    $form->setObject(new Event());

    return $form;
}

字段集

 public function __construct(ObjectManager $om, $options = array())
{
    parent::__construct('multimail');

    $this->add(array(
        'type' => 'Zend\Form\Element\Hidden',
        'name' => 'id'
    ));

    $this->add(array(
        'type' => 'Zend\Form\Element\Hidden',
        'name' => 'eventid'
    ));

    // add current eventID to fetch addresses
    $this->add(array(
        'type'    => 'DoctrineModule\Form\Element\ObjectSelect',
        'name'    => 'extadressen',
        'attributes' => array(
            'class'     => 'form-control',
            'id'        => 'singleExtSel',
            'multiple'  => 'multiple',
        ),
        'options' => array(
            'object_manager' => $om,
            'target_class'   => 'Mat\Entity\AdressenExt',
            'property'       => 'email',
            'is_method'      => true,
            'find_method'    => array(
                'name'   => 'getExtAdressen',
                'params' => array(
                    'criteria' => array('userid' => $options['userid'], 'eventid' => $options['eventid']),
                ),
            ),
        ),
    )); ...
