在我的 CRUD 应用程序中,我在 addAction 中遇到了问题。在控制器上,逻辑未通过 $form->isValid() 验证,但表单没有显示任何错误消息。
我尝试使用以下代码(感谢Sam):
foreach($form->get('product')->getElements() as $el)
{
echo $el->getName()." = ".$el->getValue()." > ".$el->getMessages()." <br/>";
}
这只显示字段的名称和值,但不包括错误消息。
我尝试让表单完全为空,它会触发“值是必需的,不能为空”错误消息,但是,然后,我逐个填写每个字段,直到我不再收到更多的错误消息,但表单仍然无效。
我的表单有一个产品Fieldset作为基本Fieldset和一个提交按钮。在Product Fieldset中,我有一个ID字段、一个名称字段、一个价格字段和一个品牌Fieldset。在我的品牌Fieldset内,我有一个id字段。像这样:
ProductForm:
class ProductForm extends Form
{
public function init()
{
// we want to ignore the name passed
parent::__construct('product');
$this->setName('product');
$this->setAttribute('method', 'post');
$this->add(array(
'name' => 'product',
'type' => 'Administrador\Form\ProductFieldset',
'options' => array(
'use_as_base_fieldset' => true
),
));
$this->add(array(
'name' => 'submit',
'type' => 'Submit',
'attributes' => array(
'value' => 'Add',
'id' => 'submitbutton',
),
));
}
}
产品字段集:
class ProductFieldset extends Fieldset implements ServiceLocatorAwareInterface
{
protected $serviceLocator;
function __construct($name = null)
{
parent::__construct('product_fieldset');
$this->setHydrator(new ArraySerializableHydrator());
$this->setObject(new Product());
}
public function init()
{
$this->add(array(
'name' => 'id',
'type' => 'Hidden',
));
$this->add(array(
'name' => 'name',
'type' => 'Text',
'options' => array(
'label' => 'Name',
),
));
$this->add(array(
'name' => 'price',
'type' => 'Text',
'options' => array(
'label' => 'Price',
),
));
$this->add(array(
'name' => 'brand',
'type' => 'BrandFieldset',
));
}
public function setServiceLocator(ServiceLocatorInterface $sl)
{
$this->serviceLocator = $sl;
}
public function getServiceLocator()
{
return $this->serviceLocator;
}
}
品牌字段集:
class BrandFieldset extends Fieldset
{
function __construct(BrandTable $brandTable)
{
parent::__construct('brand_fieldset');
//$this->setHydrator(new ClassMethodsHydrator(false))->setObject(new Brand());
$this->setHydrator(new ArraySerializableHydrator());
$this->setObject(new Brand());
$brandSelectOptionsArray = $brandTable->populateSelectBrand();
$this->add(array(
'name' => 'id',
'type' => 'Select',
'options' => array(
'label' => 'Brand',
'empty_option' => 'Please select a brand',
'value_options' => $brandSelectOptionsArray,
),
));
}
}
这是我在addAction中的新表单语句:
$formManager = $this->serviceLocator->get('FormElementManager');
$form = $formManager->get('Administrador\Form\ProductForm');
在我的“产品”模型中,我有输入筛选器,“id”字段需要的筛选器,以及“名称”字段需要的筛选器。并且对于品牌字段,我创建了另一个输入筛选器,并将其添加到主要的输入筛选器中。
$brandFilter->add($factory->createInput(array(
'name' => 'id',
'required' => true,
'filters' => array(
array('name' => 'Int'),
),
)));
$inputFilter->add($brandFilter, 'brand');
奇怪的行为是,我的editAction正常工作并具有相同的逻辑。
是否有一种形式的从表单中回显内部错误消息的方法,帮助我理解为什么表单无效。

这是我的完整控制器:
class ProductController extends AbstractActionController
{
protected $productTable;
protected $brandTable;
public function indexAction()
{
return new ViewModel(array(
'products' => $this->getProductTable()->fetchAll(),
));
}
public function addAction()
{
$formManager = $this->serviceLocator->get('FormElementManager');
$form = $formManager->get('Administrador\Form\ProductForm');
$form->get('submit')->setValue('Add');
$request = $this->getRequest();
if ($request->isPost()) {
$product = new Product();
$product->brand = new Brand();
$form->setInputFilter($product->getInputFilter());
$form->setData($request->getPost());
if ($form->isValid()) {
$product->exchangeArray($form->getData());
$this->getProductTable()->saveProduct($product);
// Redirect to list of products
return $this->redirect()->toRoute('product');
}
}
return new ViewModel(array(
'form' => $form,
));
}
public function editAction()
{
$id = (int) $this->params()->fromRoute('id', 0);
if (!$id) {
return $this->redirect()->toRoute('product', array(
'action' => 'add'
));
}
// Get the Product with the specified id. An exception is thrown
// if it cannot be found, in which case go to the index page.
try {
$product = $this->getProductTable()->getProduct($id);
}
catch (\Exception $ex) {
return $this->redirect()->toRoute('product', array(
'action' => 'index'
));
}
$formManager = $this->serviceLocator->get('FormElementManager');
$form = $formManager->get('Administrador\Form\ProductForm');
$brand = $this->getBrandTable()->getBrand($product->brand);
$product->brand = $brand;
$form->bind($product);

$request = $this->getRequest();

$this->getProductTable()->saveProduct($form->getData());
// Redirect to list of products
return $this->redirect()->toRoute('product');
}
}
return array(

}
public function deleteAction()

);
}

$sm = $this->getServiceLocator();
$this->productTable = $sm->get('Administrador\Model\ProductTable');
}

public function getBrandTable()
{
if (!$this->brandTable) {
$sm = $this->getServiceLocator();

}
