Question

我遇到bind（）表单的问题。当我在editAction中调用bind时发生此错误。错误是：

的Zend \表格\异常\ InvalidArgumentException

当我删除bind（）时，所有成功执行但当我调用form-＆gt; bind时发生此错误。我读了doc，又读了一些。

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

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

Answer 2

请看你的getPhonebookItem函数，可能是你没有回报。你必须返回一些$ row。

像这样......

$row = $rowset->current();

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

Answer 3

我的情况中的错误是当我尝试使用Doctrine的实体管理器检索实体时它返回null。然后我将null / false值传递给$ form-＆gt; bind（）：

    $form->bind( $requestEntity );

这产生了错误。

Answer 4

我在使用Doctrine开发的项目中遇到了同样的错误。使用Doctrine，相当于你的

$phonebook = $this->getPhonebookTable()->getPhonebookItem($id);

可能类似于

$phonebook = $this->getEntityManager()->find('PhonebookModule\Entity\Phonebook', $id);

我的表单一直有效，直到我需要使用不同的列从数据库中选择一行。而不是

public function editAction()
    {
        $id = (int) $this->params()->fromRoute('id', 0);

        // ...

            $phonebook = $this->getEntityManager()->find('PhonebookModule\Entity\Phonebook', $id);

            // ...

我需要像

这样的东西

public function editAction()
    {
        $firstname = $this->params()->fromRoute('firstname', 0);

        // ...

            $phonebook = $this->getEntityManager()->find('PhonebookModule\Entity\Phonebook', $firstname);

            // ...

虽然我在两种方法中采用了相同的策略，但后者导致setObject expects an object argument received “”错误。经过大量的血，汗和泪，我最终发现填充$phonebook变量的功能不起作用。在Doctrine中，find(）函数仅在列参数用于已设置为实体中数据集的id的列时才有效。如果要根据其他列选择行，则必须使用findBy()或findOneBy()。换句话说，如果$id已被命名为实体中数据集的ID，则

// this works:
$phonebook = $this->getEntityManager()->find('PhonebookModule\Entity\Phonebook', $id);

// this doesn’t work:     
$phonebook = $this->getEntityManager()->find('PhonebookModule\Entity\Phonebook', $firstname);

// this works:
$phonebook = $this->getEntityManager()->findOneBy('PhonebookModule\Entity\Phonebook', $firstname);

虽然我们的代码不同，但也许我的经验可以帮助您找出问题所在：数据存在于数据模型中;但是，无论出于何种原因，将该数据放入变量的功能都不起作用。
