I have this field in my form:
->add('taskOwner', null, array(
'label' => $this-> translator ->trans( 'tasks.index.responsible' , array() , 'crm' )))
Symfony recognize it as Choice Type (it's have foreign key to another table, with users). Now i want to set the default value on the logged user. How I can do that ? I tried in my controller create new entity of my type, set taskOwner into it and then by SetData put in into form, like this:
$entity = new Tasks();
$tasksForm = $this->createForm(new TasksType($translator), $entity);
$userId = $this->get('security.context')->getToken()->getUser()->getId();
$user = $this->getDoctrine()->getRepository('CloudAdmBundle:AdmUser')->find($userId);
$task = new Tasks();
$task->setTaskOwner($user);
$tasksForm->setData($task);
To clear everything, definition of setter:
public function setTaskOwner(\Cloud\AdmBundle\Entity\AdmUser $taskOwner = null)
{
$this->taskOwner = $taskOwner;
return $this;
}
Do it before you create the form:
$userId = $this->get('security.context')->getToken()->getUser()->getId();
$user = $this->getDoctrine()->getRepository('CloudAdmBundle:AdmUser')->find($userId);
$entity = new Tasks();
$entity->setTaskOwner($user);
$tasksForm = $this->createForm(new TasksType($translator), $entity);

Our application uses several webforms and some of them only should add or change several parameters in the querystring. As example there are a filter form and a form for the list order (just a dropdown).
Both are indipendant, but if I change one, I have to pass the current querystring parameters with the new request. How can I manage it?
This is just one of the possible solutions, it will depend on your implementation if it would help you.
<?php
$allowedQueryParams = array('param1', 'param2', 'param3');
// I'll fake a request here
$request = new Request(array('param2' => 'foo', 'param3' => 'bar', 'param4' => 'dummy'));
$formFactory = Forms::createFormFactoryBuilder()->getFormFactory();
$formBuilder = $formFactory->createBuilder();
$formBuilder->add('param1', 'text');
$data = array();
foreach ($allowedQueryParams as $param) {
if ($request->query->has($param)) {
// Add the query param as hidden field to you form
$formBuilder->add($param, 'hidden');
$data[$param] = $request->query->get($param);
}
}
$formBuilder->setData($data);
$form = $formBuilder->getForm();
So basically you add hidden fields with the current query parameters.
Edit:
But if you would have many forms, you might want to do this with an EventSubscriber
An alternative approach would be to combine the two forms into one master form.
From your controller:
$formData = array(
'filterParams' => array(), // Default filter parameters
'listOrderParams' => array(), // Default list order parameters
);
$form = $this->createFormBuilder($task)
->add('filterParams', new FilterFormType())
->add('listOrderParams', new ListOrderFormType())
->add('update', 'submit')
->getForm();
$form->handleRequest($request);
if ($form->isValid()) {
$formData = $form->getData();
I want to make a quiz(really simple one) for my student. I have 2 entity one question and one answer with a relation onetomany frome answer entity.
I want to be able to write the questions for a tex X and put all of them in a page with a field answer.
Exemple:
1) question 1
<input name question1>
2) question 2
<input name question2>
I did this for the moment:
public function newAction() {
$em = $this->getDoctrine()->getManager();
$entities = $em->getRepository('AdminQuizBundle:Question')->findAll();
$questions = array();
$forms = array();
foreach ($entities as $question) {
$entity = new Reponse();
$form = $this->createForm(new ReponseType(), $entity);
$questions[] = $question;
$forms[] = $form->createView();
}
return array(
'entity' => $entity,
'form' => $forms,
'questions' => $questions,
);
}
it works but went i try to save just the last one did
I am new to zend. I am trying to create login form using zend framework. But its creating problem. Below is my function
public function loginAction()
{
$db = $this->_getParam('db');
$form = new Application_Form_Login();
$this->view->form = $form;
if($this->getRequest()->isPost())
{
$formData = $this->getRequest()->getPost();
if ($form->isValid($formData))
{
$adapter = new Zend_Auth_Adapter_DbTable(
$db,
'users',
'emailaddress',
'password',
'MD5(CONCAT(?, password_salt))'
);
$adapter->setIdentity($form->getValue('email'));
$adapter->setCredential($form->getValue('password'));
$auth = Zend_Auth::getInstance();
$result = $auth->authenticate($adapter);
if ($result->isValid()) {
$this->_helper->FlashMessenger('Successful Login');
$this->_redirect('/');
return;
}
}
}
}
its giving error on following line -> $result = $auth->authenticate($adapter);
Error is -> Message: The supplied parameters to Zend_Auth_Adapter_DbTable failed to produce a valid sql statement, please check table and column names for validity.
my table name is 'users' and it has columns(id,firstname,lastname,age,emailaddress,password).
You need field named 'password_salt' in your table which will contain salt or just change this
'MD5(CONCAT(?, password_salt))'
to
'MD5(?)'
Can anyone please show me a specific example of a Symfony2 form entity update? The book only shows how to create a new entity. I need an example of how to update an existing entity where I initially pass the id of the entity on the query string.
I'm having trouble understanding how to access the form again in the code that checks for a post without re-creating the form.
And if I do recreate the form, it means I have to also query for the entity again, which doesn't seem to make much sense.
Here is what I currently have but it doesn't work because it overwrites the entity when the form gets posted.
public function updateAction($id)
{
$em = $this->getDoctrine()->getEntityManager();
$testimonial = $em->getRepository('MyBundle:Testimonial')->find($id);
$form = $this->createForm(new TestimonialType(), $testimonial);
$request = $this->get('request');
if ($request->getMethod() == 'POST') {
$form->bindRequest($request);
echo $testimonial->getName();
if ($form->isValid()) {
// perform some action, such as save the object to the database
//$testimonial = $form->getData();
echo 'testimonial: ';
echo var_dump($testimonial);
$em->persist($testimonial);
$em->flush();
return $this->redirect($this->generateUrl('MyBundle_list_testimonials'));
}
}
return $this->render('MyBundle:Testimonial:update.html.twig', array(
'form' => $form->createView()
));
}
Working now. Had to tweak a few things:
public function updateAction($id)
{
$request = $this->get('request');
if (is_null($id)) {
$postData = $request->get('testimonial');
$id = $postData['id'];
}
$em = $this->getDoctrine()->getEntityManager();
$testimonial = $em->getRepository('MyBundle:Testimonial')->find($id);
$form = $this->createForm(new TestimonialType(), $testimonial);
if ($request->getMethod() == 'POST') {
$form->bindRequest($request);
if ($form->isValid()) {
// perform some action, such as save the object to the database
$em->flush();
return $this->redirect($this->generateUrl('MyBundle_list_testimonials'));
}
}
return $this->render('MyBundle:Testimonial:update.html.twig', array(
'form' => $form->createView()
));
}
This is actually a native function of Symfony 2 :
You can generate automatically a CRUD controller from the command line (via doctrine:generate:crud) and the reuse the generated code.
Documentation here :
http://symfony.com/doc/current/bundles/SensioGeneratorBundle/commands/generate_doctrine_crud.html
A quick look at the auto-generated CRUD code by the Symfony's command generate:doctrine:crudshows the following source code for the edit action
/**
* Displays a form to edit an existing product entity.
*
* #Route("/{id}/edit", name="product_edit")
* #Method({"GET", "POST"})
*/
public function editAction(Request $request, Product $product)
{
$editForm = $this->createForm('AppBundle\Form\ProductType', $product);
$editForm->handleRequest($request);
if ($editForm->isSubmitted() && $editForm->isValid()) {
$this->getDoctrine()->getManager()->flush();
return $this->redirectToRoute('product_edit', array('id' => $product->getId()));
}
return $this->render('product/edit.html.twig', array(
'product' => $product,
'edit_form' => $editForm->createView(),
));
}
Note that a Doctrine entity is passed to the action instead of an id (string or integer). This will make an implicit parameter conversion and saves you from manually fetching the corresponding entity with the given id.
It is mentioned as best practice in the Symfony's documentation
Is there any good solution for the following requirements:
A form with one field for zip code and default validators like number, length, etc.
After submission, the form is checked against a database.
If the zip code is not unique we have to ask for an city.
Examples:
Case 1: Submited zip code is unique in database. Everything is okay. Process form
Case 2: Submited zip code is not unique. Add a second field for city to the form. Go back to form.
We want to handle this in an generic way (not inside an controller). We need this logic for
a lot of forms. First thought was to add it to isValid() to every form or write a
validator with logic to add fields to the form. Subforms are not possible for us, because we need this for different fields (e.g. name and street).
Currently I'm using isValid method inside my forms for an User Form to verify the password and confirm password field. Also, when the form is displayed in a New Action, there are no modifications, but when displayed in an Edit Action, a new field is added to the form.
I think that is a good option work on the isValid method and add the field when the validation return false, and if you want something more maintainable, you should write your own validatator for that purpose.
Take a look at my code:
class Admin_Form_User extends Zf_Form
{
public function __construct($options = NULL)
{
parent::__construct($options);
$this->setName('user');
$id = new Zend_Form_Element_Hidden('id');
$user = new Zend_Form_Element_Text('user');
$user->setLabel('User:')
->addFilter('stripTags')
->addFilter('StringTrim')
->setAllowEmpty(false)
->setRequired(true);
$passwordChange = new Zend_Form_Element_Radio('changePassword');
$passwordChange->setLabel('Would you like to change the password?')
->addMultiOptions(array(1 => 'Sim', 2 => 'Não'))
->setValue(2)
->setSeparator('');
$password = new Zend_Form_Element_Password('password');
$password->setLabel('Password:')
->addFilter('stripTags')
->addFilter('StringTrim')
->setRequired(true);
$confirm_password = new Zend_Form_Element_Password('confirm_password');
$confirm_password->setLabel('Confirm the password:')
->addFilter('stripTags')
->addFilter('StringTrim')
->addValidator('Identical')
->setRequired(true);
$submit = new Zend_Form_Element_Submit('submit');
$submit->setLabel('Save');
$this->addElements(array($id,$name,$lastname,$group,$user,$passwordChange,$password,$confirm_password,$submit));
$this->addDisplayGroup(array('password','confirm_password'),'passwordGroup');
$this->submit->setOrder(8);
$this->setDisplayGroupDecorators(array(
'FormElements',
array('HtmlTag', array('tag' => 'div','id' => 'div-password'))
)
);
$passwordChange->clearDecorators();
}
public function addPasswordOption()
{
$this->changePassword->loadDefaultDecorators();
$this->getDisplayGroup('passwordGroup')
->addDecorators(array(
array('HtmlTag', array('tag' => 'div','id' => 'div-password'))
)
);
$this->password->setRequired(false);
$this->confirm_password->setRequired(false);
}
public function setPasswordRequired($flag = true)
{
$this->password->setRequired($flag);
$this->confirm_password->setRequired($flag);
}
public function isValid($data)
{
$confirm = $this->getElement('confirm_password');
$confirm->getValidator('Identical')->setToken($data['password']);
return parent::isValid($data);
}
}
So, in my controller:
public function newAction()
{
$this->view->title = "New user";
$this->view->headTitle($this->view->title, 'PREPEND');
$form = $this->getForm();
if($this->getRequest()->isPost())
{
$formData = $this->_request->getPost();
if($form->isValid($formData))
{
$Model = $this->getModel();
$id = $Model->insert($formData);
$this->_helper->flashMessenger('The user data has beed updated.');
$this->_helper->redirector('list');
}
}
$this->view->form = $form;
}
public function editAction()
{
$this->view->title = "Edit user";
$this->view->headTitle($this->view->title, 'PREPEND');
$id = $this->getRequest()->getParam('id');
$form = $this->getForm();
// Add yes or no password change option
$form->addPasswordOption();
$Model = $this->getModel();
if($this->getRequest()->isPost())
{
$formData = $this->getRequest()->getPost();
// Change password?
if($formData['changePassword'] == 2) $form->setPasswordRequired(false);
if($form->isValid($formData))
{
$Model->update($formData);
$this->_helper->flashMessenger('The user data has beed updated.');
$this->_helper->redirector('list');
}
}
$data = $Model->getById($id)->toArray();
$form->populate($data);
$this->view->form = $form;
}
You will probably need a Javascript form validator for that. In the submit function perform an AJAX call to check if the zipcode is unique. If not, show an extra city field.
But you still have to perform the validation server side: never trust user input, even if it's validated on the client side.
