我的产品实体有11个字段，我想只更新4个字段来更新我的productController的updateAction。在我的更新视图中，我只显示我想要更新的4个字段。除了在更新之后它将产品表的剩余字段更新为null之外，每件事都可以正常工作。 野兔是我的updateAction
public function updateAction()
{
$pid = (int) $this->params()->fromRoute('pid', 0);
if (!$pid) {
return $this->redirect()->toRoute('product', array(
'action' => 'add'
));
}
$product = $this->getProductTable()->getProduct($pid);
$form = new ProductForm();
$form->setValidationGroup('product_name', 'bv','price');
$form->bind($product);
$form->get('submit')->setAttribute('value', 'Edit');
$request = $this->getRequest();
if ($request->isPost()) {
$form->setInputFilter($product->getInputFilter());
$form->setData($request->getPost());
if ($form->isValid()) {
$this->getProductTable()->saveProduct($form->getData());
$this->flashMessenger()->addSuccessMessage("Product ".$product->getProduct_name()." updated Succesfully");
// Redirect to list of products
return $this->redirect()->toRoute('product');
}
}
return array(
'pid' => $pid,
'form' => $form,
);
}

saveproduct方法就在这里
public function saveProduct(Product $product)
{
$data =$product->getArrayCopy();
$pid = (int)$product->getPid();
if ($pid == 0) {
$this->tableGateway->insert($data);
} else {
if ($this->getProduct($pid)) {
$this->tableGateway->update($data, array('pid' => $pid));
} else {
throw new \Exception('Product id does not exist');
}
}
}
提前感谢您的宝贵建议。

问题在于您的 exchangeArray（）方法。我有类似的问题。我通过将模型的exchangeArray（）方法改为这样的方法来解决。
<?php
namespace Admin\Model;
use Zend\InputFilter\InputFilter;
use Zend\InputFilter\InputFilterAwareInterface;
use Zend\InputFilter\InputFilterInterface;
class Category implements InputFilterAwareInterface{
public $category_id=0;
public $name;
public $slug;
public $position=0;
public $news_count=0;
public $status=0;
protected $inputFilter;
public function setInputFilter(InputFilterInterface $InputFilter){
throw new Exception("Not used");
}
public function getInputFilter(){
if(!$this->inputFilter){
$filter=new InputFilter();
// now define filters
$filter->add(array(
'name'=>'category_id',
'required'=>'true',
'filters'=>array(array('name'=>'Int'))
));
$filter->add(array(
'name'=>'name',
'required'=>'true',
'filters'=>array(
array('name'=>'StripTags'),
array('name'=>'StringTrim'),
),
'validators'=>array(
array(
'name'=>'StringLength',
'options'=>array(
'encoding'=>'UTF-8',
'min'=>'3',
'max'=>'100',
)
)
)
));
$filter->add(array(
'name'=>'position',
'filters'=>array(array('name'=>'Int')),
));
$this->inputFilter=$filter;
}
return $this->inputFilter;
}
public function exchangeArray($data){
if(isset($data['category_id'])){
$this->category_id=$data['category_id'];
}
if(isset($data['name'])){
$this->name=$data['name'];
}
if(isset($data['slug'])){
$this->slug=$data['slug'];
}
if(isset($data['status'])){
$this->status=$data['status'];
}
if(isset($data['news_count'])){
$this->news_count=$data['news_count'];
}
if(isset($data['position'])){
$this->position=$data['position'];
}
}
public function getArrayCopy()
{
return get_object_vars($this);
}
}
我之前的exchangeArray（）方法是
public function exchangeArray($data){
$this->category_id=(!empty($data['category_id'])) ? $data['category_id']:0;
$this->name=(!empty($data['name'])) ? $data['name'] : null;
$this->position=(!empty($data['position'])) ? $data['position']:0;
$this->status=(!empty($data['status'])) ? $data['status'] : 0;
$this->slug=(!empty($data['slug'])) ? $data['slug'] : null;
$this->newsCount=(!empty($data['news_count'])) ? $data['news_count'] : 0;
}

您已将产品绑定到表单，因此而不是$form->getData()将$product传递给save方法：
$this->getProductTable()->saveProduct($product);
由于产品具有剩余的字段值，因此不会将其覆盖为null
如果那不是问题那么你需要提供saveProduct方法体来看看它是什么......
