我无法弄清楚为什么我的Zend表单没有更新为新值。我非常密切地关注了Album示例，但无法弄清楚我哪里出错了。目前，Form未通过IsValid IF语句。如果我将保存行放在此检查上方，则无论表单框中的新信息是什么，它似乎都会重新输入旧信息。有什么想法吗？
以下编辑行动：
public function editLicenceAction()
{
$dbAdapter = $this->getServiceLocator()->get('Zend\Db\Adapter\Adapter');
$pro_id='22';
$licence_id = (int) $this->params()->fromRoute('licence_id', 0);
if (!$licence_id) {
return $this->redirect()->toRoute('proLicence', array(
'action' => 'index'
));
}
try {
$proLicence = $this->getProLicenceTable()->getProLicence($licence_id);
}
catch (\Exception $ex) {
return $this->redirect()->toRoute('proLicence', array(
'action' => 'index'
));
}
$form = new ProLicenceForm($dbAdapter);
$form->bind($proLicence);
$form->get('submit')->setAttribute('value', 'Edit');
$request = $this->getRequest();
if ($request->isPost()) {
//$form->setInputFilter($proLicence->getInputFilter());
$form->setData($request->getPost());
echo 'I got Request';
if ($form->isValid()) {
echo 'I got Save';
$this->getProLicenceTable()->saveProLicence($proLicence);
return $this->redirect()->toRoute('proLicence');
}
}
return array(
'licence_id' => $licence_id,
'form' => $form,
);
}
见下图：
$title = 'Edit Licence';
$this->headTitle($title);
?>
<h1><?php echo $this->escapeHtml($title); ?></h1>
<?php
$form = $this->form;
$form->setAttribute('action', $this->url(
'proLicence',
array(
'action' => 'editLicence',
'licence_id' => $this->licence_id,
)
));
$form->prepare();
echo $this->form()->openTag($form);
echo $this->formHidden($form->get('licence_id'));
echo $this->formRow($form->get('licence_name_id'));
echo $this->formRow($form->get('licence_number'));
echo $this->formSubmit($form->get('submit'));
echo $this->form()->closeTag();

非常感谢，M
更新：以下作品（从专辑示例中复制）。这就是我用来解决问题的麻烦。
public function editAction()
{
$id = (int) $this->params()->fromRoute('id', 0);
if (!$id) {
return $this->redirect()->toRoute('album', array(
'action' => 'add'
));
}
// Get the Album with the specified id. An exception is thrown
// if it cannot be found, in which case go to the index page.
try {
$album = $this->getAlbumTable()->getAlbum($id);
}
catch (\Exception $ex) {
return $this->redirect()->toRoute('album', array(
'action' => 'test'
));
}
$form = new AlbumForm();
$form->bind($album);
$form->get('submit')->setAttribute('value', 'Edit');
$request = $this->getRequest();
if ($request->isPost()) {
$form->setInputFilter($album->getInputFilter());
$form->setData($request->getPost());
if ($form->isValid()) {
$this->getAlbumTable()->saveAlbum($album);
Debug::dump($form);
//var_dump($album);
// Redirect to list of albums
//return $this->redirect()->toRoute('album');
}
}
return array(
'id' => $id,
'form' => $form,
);
}
更新2：比较调试似乎下面的部分没有在许可证示例上更新，但是在工作专辑示例中：
["object":protected] => object(Pro\Model\ProLicence\ProLicence)#398 (6) {
["pro_id"] => string(2) "22"
["licence_id"] => string(1) "1"
["licence_name_id"] => string(1) "5"
["licence_number"] => string(9) "345345345"
["licence_approved"] => string(1) "T"
答案 0 :(得分：0)
您是否为表单设置了方法？如果我没记错，默认方法是GET，但是您使用POST检索提交的值。尝试将表单方法明确设置为POST。
您还可以尝试使用Zend\Debug\Debug::dump($form)查看对象在不同位置包含的内容 - 但实际上您似乎并未从提交的表单中获取新值。
用于设置表单数据的方法似乎不正确 - 它应该类似于
$form->setData($this->params()->fromPost());
因为你想要的只是关联数组中的数据元素。
再次查看你的代码，错误是相当明显的 - 只是另一组眼睛！你打电话：
$this->getAlbumTable()->saveAlbum($album);
但您尚未在$ album对象中设置数据。

我忘了将隐藏的表单添加到我的编辑字段中。一旦添加它们，我就可以编辑没有问题。
echo $this->formHidden($form->get('membership_id'));
echo $this->formHidden($form->get('pro_id'));
