zend framework stringtrim filter not working - zend-framework

Question

I'm having trouble with zend framework's string trim filter. I use the following code to set up a text element in a Zend_Form:
$voucherValidator = new Project_Validate_Voucher();
$code = $this->addElement('text', 'code', array('label'=>'Gutscheincode'));
$code = $this->getElement('code')
->addFilter('StringTrim')
->addValidator($voucherValidator, true);
When I type in some text with preceeding blanks or tabs, the validator correctly works on the StringTrim filtered input and accepts the input. When I later check the $_POST['code'] after code submission, I get the unfiltered input. How can I get my text element to post the filtered value?

Answer 1

Use $code = $this->code->getValue() as Zend_Form doesn't actually filter the $_POST array.

Answer 2

Sorry, i know i'm late but in case any one faced the same problem,
I have faced this problem today and i found few ways to solve this problem:

first my code is:
This is the form class
class Application_Form_UserForm extends 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
));
}
}
This is controller class
class UserController extends 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');
}
}
}
}
First Solution:
i used filter on Form elements in the form class,
but i retrieved data from $form object in the controller,
as i found that method
addFilter()
doesn't change in the $_POST array values, so i have retrieved the data from $form object and then passed it as array to Model.
Second Solution:
i have tried to apply the filter on the values in the controller, not in the form by creating object from filter class and apply needed filter
Third Solution:
is to use method
addValidator()
with regex which affects on $_POST values.
