我有一个Zend表单用于向数据库添加内容。然后,我希望使用此表单编辑我添加到数据库中的内容。有没有可能使用此表单(从数据库填充并显示它)?
我在控制器中有以下代码:
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(
// 'title' => $result->title,
// 'story' => $result->story,
// );
if ($this->getRequest()->isPost()) {
if ($form->isValid($request->getPost())) {
$data = array(
'title' => $form->getValue("title"),
'story' => $form->getValue("story"),
);
$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'
));
}
}
在我看来:
<?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;
}
当我尝试在这个视图中改变任何值并给出除了NULL之外的值时,会出现错误提示,我无法这样做,那么是否有可能重用这个表单呢?还是不行?
谢谢!
