php - ZF2 setObject 期望收到一个对象参数“”

Question

我对 bind() 表单有疑问。当我在 editAction 中调用 bind 时出现此错误。错误是：

Zend\Form\Exception\InvalidArgumentException

文件：

/var/www/html/zf/zf-local/vendor/ZF2/library/Zend/Form/Fieldset.php:439

当我删除 bind() 所有成功执行但当我调用 form->bind 时出现此错误。我阅读了文档并再次阅读了一些。

我的编辑操作是：

    /**
     * Edit Action
     */
 public function editAction()
    {
        $id = (int) $this->params()->fromRoute('id', 0);
        if (!$id) {
            return $this->redirect()->toRoute('phonebook', array(
                'action' => 'add'
            ));
        }

        // Get the Phonebook with the specified id.  An exception is thrown
        // if it cannot be found, in which case go to the index page.
        try {
            $phonebook = $this->getPhonebookTable()->getPhonebookItem($id);
        }
        catch (\Exception $ex) {
            return $this->redirect()->toRoute('phonebook', array(
                'action' => 'index'
            ));
        }

        $form  = new PhonebookForm();
        $form->bind($phonebook);
        $form->get('submit')->setAttribute('value', 'Edit');

        $request = $this->getRequest();
        if ($request->isPost()) {

            $form->setInputFilter($phonebook->getInputFilter());
            $form->setData($request->getPost());

            if ($form->isValid()) {

                $this->getPhonebookTable()->saveItem($phonebook);

                // Redirect to list of albums
                return $this->redirect()->toRoute('phonebook');
            }
        }

        return array(
            'id' => $id,
            'form' => $form,
        );
    }

调试$phonebook：

object(Phonebook\Model\Phonebook)[254]
  protected 'filter' => null
  public 'id' => string '1' (length=1)
  public 'firstname' => string 'Ivan' (length=4)
  public 'lastname' => string 'Stojkovic' (length=11)
  public 'homephone' => string '0616278054' (length=10)
  public 'workphone' => string '013351456' (length=9)
  public 'company' => string 'Delix' (length=5)
  public 'email' => string 'office.stojmenovic@gmail.com' (length=28)
  public 'address' => string 'Voislava Ilica 8' (length=16)
  public 'city' => string 'Pancevo' (length=7)
  public 'fax' => string '21565486' (length=8)

Answer 1

请看你的 getPhonebookItem 函数，可能你什么都没有返回。您必须返回一些 $row。

像这样...

$row = $rowset->current();

if(!$row) {
    throw new \Exception("Article #$id not found");
}
return $row; //!!!!!!!!!!!!!

Answer 2

我的情况的错误是当我试图使用 Doctrine 的实体管理器检索一个实体时，它返回了 null。然后我将一个 null/false 值传递给 $form->bind()：

    $form->bind( $requestEntity );

这产生了错误。

Answer 3

$phonebook您的变量似乎为空。因此getPhonebookItem()，如果没有找到记录，您的方法似乎不会抛出异常。
