[英]How to use identical field validation for add and edit operation in zend form?
[英]How to edit Zend form with edit button next to each field
我有文件(ProfileController.php),其中包含以下代碼:
public function editAction() {
if (Zend_Auth::getInstance()->hasIdentity()) {
try {
$form = new Application_Form_NewStory();
$request = $this->getRequest();
$story = new Application_Model_DbTable_Story();
$result = $story->find($request->getParam('id'));
// $values = array(
// 'names' => $result->names,
// 'password' => $result->password,
// );
if ($this->getRequest()->isPost()) {
if ($form->isValid($request->getPost())) {
$data = array(
'names' => $form->getValue("names"),
'password' => $form->getValue("password"),
);
$form->populate($data->toArray());
$where = array(
'id' => $request->getParam('id'),
);
$story->update($data, $where);
}
}
$this->view->form = $form;
$this->view->titleS= $result->title;
$this->view->storyS= $result->story;
} catch (Exception $e) {
echo $e;
}
} else {
$this->_helper->redirector->goToRoute(array(
'controller' => 'auth',
'action' => 'index'
));
}
}
以及另一個包含以下代碼的文件(edit.phtml):
<?php
try
{
$tmp = $this->form->setAction($this->url());
//$tmp->titleS=$this->title;
//$tmp->storyS=$this->story;
//echo $tmp->title = "aaaaa";
}
catch(Exception $e)
{
echo $e;
}
?>
我希望用戶能夠編輯其用戶名和密碼。 我該怎么辦?
首先:將Zend_Auth內容上移到init()或preDispatch()上,這樣Auth將針對控制器中的任何或所有操作運行。
使一個提交按鈕起作用的訣竅是為按鈕賦予不同的名稱,以便getParam('')可以使用。
通常,我僅在執行刪除操作時才執行此類操作,對於編輯或更新操作,我只是將整個數組提交回數據庫。 我通常使用Zend_Db_Table_Row save()
方法代替Zend_Db_Table's
insert()
或update()
因此機制有所不同。
我只是使用一個簡單的表單來執行更新,這是控制器代碼(視圖只是回顯表單):
//update album information
public function updatealbumAction()
{ //get page number from session
$session = new Zend_Session_Namespace('page');
//get album id
$id = $this->getRequest()->getParam('id');
$model = new Music_Model_Mapper_Album();
//fetch the album database record
$album = $model->findById($id);
$form = new Admin_Form_Album();
//this form is used elsewhere so set the form action to this action
$form->setAction('/admin/music/updatealbum/');
if ($this->getRequest()->isPost()) {
if ($form->isValid($this->getRequest()->getPost())) {
$data = $form->getValues();//get valid and filtered form values
$newAlbum = new Music_Model_Album($data);//create new entity object
$update = $model->saveAlbum($newAlbum);//save/update album info
$this->message->addMessage("Update of Album '$update->name' complete!");//generate flash message
$this->getHelper('Redirector')->gotoSimple('update', null, null, array('page' => $session->page));//redirect back to the page the request came from
}
} else {
$form->populate($album->toArray());
$this->view->form = $form;
}
}
這是一個非常常見的更新操作。
現在,這是您可能如何使用不同的請求參數對記錄執行操作的方式。 我用它來刪除數據庫記錄,但是一切皆有可能。
public function deleteAction()
{
$session = new Zend_Session_Namespace('page');
$request = $this->getRequest()->getParams();
try {
switch ($request) {
//if
case isset($request['trackId']):
$id = $request['trackId'];
$model = new Music_Model_Mapper_Track();
$model->deleteTrack($id);
$this->message->addMessage("Track Deleted!");
break;
case isset($request['albumId']):
$id = $request['albumId'];
$model = new Music_Model_Mapper_Album();
$model->deletealbum($id);
$this->message->addMessage("Album Deleted!");
break;
case isset($request['artistId']):
$id = $request['artistId'];
$model = new Music_Model_Mapper_Artist();
$model->deleteArtist($id);
$this->message->addMessage("Artist Deleted!");
break;
default:
break;
}
$this->getHelper('Redirector')->gotoSimple('update', null, null, array('page' => $session->page));
} catch (Exception $e) {
$this->message->addMessage($e->getMessage());
$this->getHelper('Redirector')->gotoSimple('update', null, null, array('page' => $session->page));
}
}
您可以將請求參數傳遞為“提交”按鈕標簽或url或任何適合您的參數。
祝好運!
