I'm working with Symfony 4, and I want to make my own form but to make an insert i need a token that is generated by the form, there is a way to generate the form and get the or what else i can do.
public function new(Request $request): Response
{
$customer = new Customers();
$form = $this->createForm(Customers1Type::class, $customer); // <- here
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$em = $this->getDoctrine()->getManager();
$em->persist($customer);
$em->flush();
return $this->redirectToRoute('customers_index');
}
return $this->render('customers/new.html.twig', [
'customer' => $customer,
'form' => $form->createView(),
]);
}
You basically do not need to get and render the token by yourself. Symfony forms handle that internally and the form_end function renders the hidden field.
When you inspect the generated Form, you will see:
<input type="hidden" id="customer__token" name="customer[_token]" value="the_long_token_auto_generated" /></form>
Then inside your controller action's, you can get the token by the $request method's:
$token = $request->request->get('customer')['_token'];

I have a form that I use to create an event from the event dedicated CRUD, and from my planning route:
In my EventController.php, create route:
$form = $this->createForm(EvenementType::class,$event);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$event = $form->getData();
$entityManager->persist($event);
$entityManager->flush();
return $this->redirectToRoute('parametres.evenements');
}
In my PlanningController.php, index route:
$formEvent = $this->createForm(EvenementType::class,$evenement);
$formEvent->handleRequest($request);
if ($formEvent->isSubmitted() && $formEvent->isValid()) {
$evenement = $formEvent->getData();
$entityManager->persist($evenement);
$entityManager->flush();
}
I believe this behaviour should only belong in the EventController in a store route, but I'm unsure. Could someone indicate me the right way to do it?
I'm having an issue with looping a form in Symfony using while loop. When the user enters one student period and it matches a registration reiterate the form to let them enter a 2nd student period and then a 3rd. I'm not doing it correctly or could I reiterate entity=new Student(); to let them enter two entities .
public function createAction(Request $request){
$entity = new Student();
$form = $this->createCreateForm($entity);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$em = $this->getDoctrine()->getManager();
$student = $em->getRepository('AcmeDemoBundle:Payrollperiod')
->findOneBy([
'begindate'=>$form->get('beginDate')->getData(),
'lastdate'=>$form->get('lastDate')->getData()
]);
$registration = $em->getRepository('AcmeDemoBundle:Payrollweek')
->findBystartdateAndenddate(
$form->get('beginDate')->getData(),
$form->get('lastDate')->getData()
);
$counter = count($registration);
while($counter<=2) {
if ($student){
$this->addFlash('error', 'Duplicate error: Student Period already existed.' );
return $this->redirect($this->generateUrl('student'));
}
elseif ($registration){
foreach ($registration as $reg) {
$reg->setStudentid($entity);
}
$em->persist($entity);
$em->flush();
return $this->redirect($this->generateUrl('payrollperiod'));
}
else{
$this->addFlash('error', ' does not match .');
return $this->redirect($this->generateUrl('student'));
}
}
return array(
'entity' => $entity,
'form' => $form->createView(),
);
}
}
Read the documentation here http://symfony.com/doc/current/reference/forms/types/form.html#allow-extra-fields on adding fields. Your UI/Front-end should created more fields when the user needs to add a second or more periods. I should generate proper Symfony form elements and then when you post, you can handle it like a standard form post, iterating over the Request since the periods will be submitted as an array.
I did something like this in the past I adding a new form row was an AJAX call to a template that described the form input fields so I wasn't having to craft form HTML in Javascript/jQuery. .append() the template results to the form-- post and process the request.
I'm learning Symfony to move an old website from flat-PHP to a framework.
In the old website I have a page with two levels of forms: the first one is just a button with which the user accepts some conditions, while the second one sends a message to the website admin. When the user clicks the button in the first form, the page is refreshed and the second form appears. The important thing is that the user can't get access to the second form without pushing the first button.
Right now, the action method is this one:
/**
* #Route("/ask-consultation", name="ask_consultation")
*/
public function askConsultationAction(Request $request)
{
$em = $this->getDoctrine()->getManager();
$form = $form = $this->createFormBuilder()
->add('submit', SubmitType::class, array('label' => 'Confermo'))
->getForm();
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$consultation = new Consultation;
$form = $this->createForm(AskConsultationType::class, $consultation);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$consultation = $form->getData();
$em = $this->getDoctrine()->getManager();
$em->persist($consultation);
$em->flush();
return $this->redirectToRoute('homepage');
}
return $this->render('visitor/consultation/ask_step2.html.twig', [
'base_dir' => realpath($this->getParameter('kernel.root_dir').'/..').DIRECTORY_SEPARATOR,
'sidebars' => $em->getRepository('AppBundle:Sidebar')->findAllOrderedBySortingPosition(),
'form' => $form->createView(),
]);
}
When I go to /ask-consultation it shows me the button to accept certain conditions; when I click the button, it shows me the form to send the message, but when I send it, I don't get redirected to homepage, but again to the first page of /ask-consultation.
I understand why this code doesn't work, but I can't understand how to make it work. One solution could be some sort of modal dialog for the first form, but if possible I'd prefer to handle all the passages in PHP. Is it possible to split the form handling without changing the route?
The most important thing in my case is that the user can't get to the second form without first having clicked on the first button.
Render everything in a single form but use javascript (jQuery) to hide the ask-consultation part of the form. When the user clicks "Confirm", then unhide the form. This avoids the controller altogether for the confirmation step. You don't seem to be recording this confirmation anyway, so just let the client side handle things. You can still check (on form submission) to see that the "confirmation" was accepted, for example by setting a hidden variable through javascript.
It turns out the answer was quite simple.
In my mind, I had to handle the second form inside the first if ($form->isSubmitted() && $form->isValid()), but of course that's not the path taken by PHP. Everytime the route gets loaded, askConsultationAction() is run from its first instruction. I simply had to initialize both forms (with different variable names, obviously), and handle the forms one after the other, rather than one inside the other.
This code works like a charm:
/**
* #Route("/ask-consultation", name="ask_consultation")
*/
public function askConsultationAction(Request $request)
{
$em = $this->getDoctrine()->getManager();
$consultation = new Consultation;
$conditions_form = $this->createFormBuilder()
->add('submit', SubmitType::class, array('label' => 'Confermo'))
->getForm();
$consultation_form = $this->createForm(AskConsultationType::class, $consultation);
$consultation_form->handleRequest($request);
$conditions_form->handleRequest($request);
if ($conditions_form->isSubmitted() && $conditions_form->isValid()) {
return $this->render('visitor/consultation/ask_step2.html.twig', [
'base_dir' => realpath($this->getParameter('kernel.root_dir').'/..').DIRECTORY_SEPARATOR,
'sidebars' => $em->getRepository('AppBundle:Sidebar')->findAllOrderedBySortingPosition(),
'form' => $consultation_form->createView(),
]);
}
if ($consultation_form->isSubmitted() && $consultation_form->isValid()) {
$consultation = $consultation_form->getData();
$em = $this->getDoctrine()->getManager();
$em->persist($consultation);
$em->flush();
return $this->redirectToRoute('homepage');
}
return $this->render('visitor/consultation/ask_step1.html.twig', [
'base_dir' => realpath($this->getParameter('kernel.root_dir').'/..').DIRECTORY_SEPARATOR,
'sidebars' => $em->getRepository('AppBundle:Sidebar')->findAllOrderedBySortingPosition(),
'form' => $conditions_form->createView(),
]);
}
Maybe, it would be even better if I used an else... if....
How can I reset the form after submit? It's a simple search form where I show a field on the top and a table in the bottom that shows either the results based on the search or the whole list... but it does not reset, the search key remained...
/**
* #Route("/", name="plazas_index")
*/
public function indexAction(Request $request)
{
$form = $this->createForm('AppBundle\Form\BuscarType');
$form->handleRequest($request);
$repository = $this->getDoctrine()->getRepository('AppBundle:Plaza');
if ($form->isSubmitted() && $form->isValid()) {
$clave = $form['clave']->getData();
$query = $repository->createQueryBuilder('p')
->where('p.nombre LIKE :nombre')
->orWhere('p.localidad LIKE :localidad')
->setParameter('nombre', '%'.$clave.'%')
->setParameter('localidad', '%'.$clave.'%')
->orderBy('p.nombre', 'ASC')
->getQuery();
$plazas = $query->getResult();
$cant = count($plazas);
$this->addFlash($cant ? 'success' : 'warning', 'La búsqueda de '.$clave. ' ha producido '.$cant.' resultados');
//return $this->redirectToRoute('plazas_index');
}
else {
$plazas = $repository->findAll();
}
unset ($form);
$form = $this->createForm('AppBundle\Form\BuscarType');
$form->handleRequest($request);
return $this->render('admin/plazas/index.html.twig', array(
'plazas' => $plazas,
'buscar_form' => $form->createView(),
));
}
I can't redirect because I do the render at the end of the action...
Any help is welcome, thanks!!
Remove the second $form->handleRequest($request); line and you are good to go!
handleRequest takes the submitted POST or GET data and applies it to the form, so if you want a blank form then you shouldn't call that.
I'm quite new here, be patient, please.
I'm trying to make notice board project in Symfony2 using FOSUserBundle.
I try to get logged user id to put it into form created with form builder (and then to MySQL database).
One of attempts is:
public function createNoticeAction(Request $request)
{
$notice = new Notice();
$form = $this->createFormBuilder($notice)
->add("content", "text")
->add("user_id","entity",
array("class"=>"FOS/UserBundle/FOSUserBundle:", "choice_label"=>"id"))
->add("isActive", "true")
->add("category", "entity",
array("class" => "AppBundle:Category", "choice_label" => "name"))
->add("save", "submit", array("label" => "Save"))
->getForm();
$form->handleRequest($request);
$em = $this->getDoctrine()->getManager();
$em->persist($notice);
$em->flush();
return $this->redirectToRoute('app_user_showuserpage');
}
I tried many solutions again and again and I get some error.
You already have the user object Symfony > 2.1.x
In you Controller like this:
$userId = $this->getUser()->getId();
...
$notice->setUserId($userId);
$em->persist($notice);
Don't ->add field in you FormBuilder, its not safely. Set this value in you Controller and don't ->add this field in FormBuilder
for symfony 3.2.13
have excelent solution (just because is working, but is dangerous if someone discover it in pure HTML)
1) first build YourFormType class.
add normal field in Forms/YourFormType.php (if not, formbuilder tell you that you passing smth not quite right (too many fields) ; -) )
$builder
->add(
'MyModelAddedById',
HiddenType::class,
[
'label' => 'echhh', //somehow it has to be here
'attr' => ['style' => 'display:none'], //somehow it has to be here
]
);
2) in your controller
public function addSomethingAction(Request $request){
$form = $this->createForm(MyModelFormType::class);
//set field value
$request->request->set("prodModelAddedById", $this->getUser()->getId());
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$product = $form->getData();
$em = $this->getDoctrine()->getManager();
$em->persist($product);
$em->flush();
$this->addFlash('success', 'record was added');
return $this->redirectToRoute('products');
}
return $this->render(
'default.add.form.html.twig',
[
'newprod' => $form->createView(),
]
);
}
explenation:
you are passing a field and variable to formbuilder (settig it already to default value!)
and important thing, becose of BUG in my opinion - you can't in your form type set method:
public function getBlockPrefix()
{
//return 'app_bundle_my_form_type';
}
because
$request->request->set
can't work properly if your POST data from form are in bag (parameterbag)
no entity managers, no services, no listeners...
hope it helps.
