我需要一些帮助清除Zend_Form并向元素添加过滤器。现在我的印象是,当您向表单添加过滤器时,当表单发布时,过滤器作为控制器中的调度的一部分执行。
然而,在测试我的表单时我的恐怖过滤器 StripTags 似乎没有运行,我在数据中获取带有HTML标签的数据。
我的表单元素如下所示。
$address1 = new Zend_Form_Element_Textarea('address1');
$address1->addFilter('StripTags')
->addFilter('StringTrim')
->setAttrib('cols', 30)
->setAttrib('rows', 5)
->removeDecorator('DtDdWrapper')
->removeDecorator('label')
->removeDecorator('HtmlTag')
但是,如果我在文本区域中放入一些带有html标签的数据,然后使用
检查表单是否有效$formData = $this->_request->getPost();
if($form->isValid($formData){
...
数据随其中的标签返回。它仅在我通过 strip_tags()函数传递数据时删除。
我想我的问题是 StipTags 过滤器是否应该过滤,为什么不呢?我在这里想念的是什么
答案 0 :(得分:8)
在调用isValid之后,您没有发布有关如何访问数据的代码。 IIRC只有通过$form->getValue('someElement')
或其他方式访问数据时,过滤器才会生效。

对不起,我知道我迟到了,以防任何人面临同样的问题,
我今天遇到了这个问题,我找到了解决这个问题的方法:
首先我的代码是:
这是表单类
类Application_Form_UserForm扩展了Zend_Form {
public function init() {
/* Form Elements & Other Definitions Here ... */
$this->setMethod('POST');
$fname = new Zend_Form_Element_Text('fname');
$fname->setLabel('First Name: ');
$fname->setAttribs(Array(
'placeholder'=>'Example: Eslam',
'class'=>'form-control'
));
$fname->setRequired();
$fname->addValidator('StringLength', false, Array(4,20));
$fname->addFilter('StringTrim');
$fname->addFilter('StripTags');
$fname->removeDecorator('DtDdWrapper');
$fname->removeDecorator('label');
$fname->removeDecorator('HtmlTag');
$lname = new Zend_Form_Element_Text('lname');
$lname->setLabel('Last Name: ');
$lname->setAttribs(Array(
'placeholder'=>'Example: Khoga',
'class'=>'form-control'
));
$lname->setRequired();
$lname->addValidator('StringLength', false, Array(4,20));
$lname->addFilter('StringTrim');
$lname->addFilter('StripTags');
$lname->removeDecorator('DtDdWrapper');
$lname->removeDecorator('label');
$lname->removeDecorator('HtmlTag');
$email = new Zend_Form_Element_Text('email');
$email->setLabel('Email: ');
$email->setAttribs(Array(
'placeholder'=>'Example@Example.com',
'class'=>'form-control'
));
$email->setRequired();
$email->addValidator('StringLength', false, Array(5,250));
$email->addFilter('StringTrim');
$email->addFilter('StripTags');
$email->removeDecorator('DtDdWrapper');
$email->removeDecorator('label');
$email->removeDecorator('HtmlTag');
$gender = new Zend_Form_Element_Select('gender');
$gender->setRequired();
$gender->addMultiOption('male','Male')->
addMultiOption('female','Female')->
addMultiOption('none','Prefer not to mention');
$gender->setAttrib('class', 'form-control');
$track_obj = new Application_Model_Track();
$allTracks = $track_obj->listAll();
$track = new Zend_Form_element_Select('track');
foreach($allTracks as $key=>$value)
{
$track->addMultiOption($value['id'], $value['name']);
}
$submit= new Zend_Form_Element_Submit('submit');
$submit->setAttribs(array('class'=>'btn btn-success'));
$reset= new Zend_Form_Element_Submit('reset');
$reset->setAttribs(array('class'=>'btn btn-danger'));
$this->addElements(array(
$fname,
$lname,
$email,
$gender,
$track,
$submit,
$reset
));
}
}
这是控制器类
类UserController扩展了Zend_Controller_Action {
public function init()
{
/* Initialize action controller here */
}
public function indexAction()
{
// action body
}
public function listAction()
{
// action body
$user_model = new Application_Model_User();
$this->view->users = $user_model->listUsers();
$track_form = new Application_Form_Track();
$this->view->track_form = $track_form;
$track_model = new Application_Model_Track();
$request = $this->getRequest();
if($request->isPost())
{
if($track_form->isValid($request->getPost())){
$track_model-> addTrack($request->getParams());
$this->redirect('/user/add');
}
}
}
public function detailsAction()
{
// action body
$user_model = new Application_Model_User();
$us_id = $this->_request->getParam("uid");
$user = $user_model->userDetails($us_id);
$trackModel = new Application_Model_Track();
$track = $trackModel->getTrackName($user[0]['track']);
$user[0]['track'] = $track[0]['name'];
$this->view->user = $user[0];
}
public function deleteAction()
{
// action body
$user_model = new Application_Model_User();
$us_id = $this->_request->getParam("uid");
$user_model->deleteUser($us_id);
$this->redirect("/user/list");
}
public function addAction()
{
// action body
$form = new Application_Form_UserForm();
$request = $this->getRequest();
if($request->isPost()){
if($form->isValid($request->getPost())){
/*echo "<pre>";
print_r($form);
echo "</pre>";
exit;*/
$userData['fname'] = $form->getValue('fname');
$userData['lname'] = $form->getValue('lname');
$userData['email'] = $form->getValue('email');
$userData['gender'] = $form->getValue('gender');
$userData['track'] = $form->getValue('track');
$user_model = new Application_Model_User();
$user_model-> addNewUser($userData);
$this->redirect('/user/list');
}
}
$this->view->user_form = $form;
}
public function editAction()
{
// action body
$form = new Application_Form_UserForm();
$user_model = new Application_Model_User ();
$id = $this->_request->getParam('uid');
$user_data = $user_model-> userDetails($id)[0];
$form->populate($user_data);
$this->view->userName = $user_data['fname']." ".$user_data['lname'];
$this->view->user_form = $form;
$request = $this->getRequest();
if($request->isPost()){
if($form->isValid($request->getPost())){
$userData['fname'] = $form->getValue('fname');
$userData['lname'] = $form->getValue('lname');
$userData['email'] = $form->getValue('email');
$userData['gender'] = $form->getValue('gender');
$userData['track'] = $form->getValue('track');
$user_model-> updateUser($id, $userData);
$this->redirect('/user/list');
}
}
}
}
第一个解决方案:
我在表单类的表单元素上使用了过滤器, 但我从控制器中的 $ form 对象检索数据, 因为我找到了方法
addFilter()方法
在$ _POST数组值中没有变化,所以我从$ form对象中检索了数据,然后将它作为数组传递给Model。
第二个解决方案:
我试图通过从过滤器类创建对象并应用所需的过滤器来对控制器中的值应用过滤器,而不是在表单中
第三个解决方案:
是使用方法
在addValidator()
使用 regex 影响$ _POST值。
