Symfony form not valid and not submittable - forms

Question

When trying to submit my form, it is not working. The button is not doing anything at all. So I tried to dump something withing my:
if ($form->isValid() && $form->isSubmitted())
And realized that it's not even entering the if statement, so I assume that there is something wrong with my form. But I can't yet figure out what it would be, so I would be glad if anyone could help me!
/**
* #Route("/document/bulkdeactivate", name="documentBundle_document_bulkDeactivate")
* #Template()
*/
public function bulkDeactivateAction(Request $request) {
$em = $this->getDoctrine()->getManager();
$selected_documents = $request->request->all();
$form = $this->createForm(DocumentDeactivationType::class);
$form->handleRequest($request);
if ($form->isValid() && $form->isSubmitted()) {
foreach($selected_documents as $document) {
$documentR = json_decode(json_encode($document), true);
dump($documentR);
for($i=0; $i<count($documentR); $i++){
$doc = $em->getRepository('DocumentBundle:Document')->findOneById($documentR[$i]);
dump($doc);
$doc->setActive(false);
$em->persist($doc);
$em->flush();
}
}
$this->addFlash(
'success',
'The document has been deactivated!'
);
return $this->redirectToRoute('documentBundle_document_list');
}
return $this->render('DocumentBundle:Panels:ActivationPanel.html.twig', array(
'form' => $form->createView(),
));
}
my Form Type:
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('documentlist', EntityType::class, array(
'class' => 'DocumentBundle:Document',
'choice_label' => 'name',
'required' => false,
'multiple' => true,
'expanded' => false,
'placeholder' => "Select Documents",
'label' => 'label.document_list',
))
->add('submit', SubmitType::class, array(
'label' => 'Submit',
'attr' => array(
'class' => 'btn btn btn-default',
),
));
}
And the form part of my twig template:
{% block content %}
{{ form_start(form) }}
{{ form(form.documentlist) }}
{{ form(form.submit) }}
{{ form_end(form) }}
{% endblock content %}
There must be some issues with the form, do you have any advice for my?

Answer 1

Actually there are several issues:
you cannot add a submit button that is not bound to a Symfony form in your case because Symfony will not identify it properly (for lack of a name that has to match SF's automatic input names generation)
In your formBuilder put:
$builder->add('submit', SubmitType::class);
your form has an incorrect name ("form") that conflicts with Twig's form() function, you have to change it,
you might have an issue (not tested, just a guess) regarding the many calls made to Twig's form() because this function dumps the whole form content, to manually dump each part use
Your {% block content %} should have this:
{{ form_widget(form.your_widget_name, attrs) }}

Answer 2

I eventually solved my issue:
1. as pointed out by #NaeiKinDus, I needed a Submit button that actually belonged to my form, plus I changed my form name to a custom deactivationForm
{% block content %}
{{ form(deactivationForm) }}
{% endblock content %}
the buildForm method:
$builder
->add('documentlist', EntityType::class, array(
'class' => 'DocumentBundle:Document',
'choice_label' => 'name',
'required' => false,
'multiple' => true,
'expanded' => false,
'placeholder' => "Select Documents",
'label' => 'label.document_list',
'translation_domain' => 'Documents',
'query_builder' => function (EntityRepository $er) {
return $er->createQueryBuilder('d')
->where('d.active = FALSE');
},
))
->add('submit', SubmitType::class, array(
'label' => 'Submit',
'attr' => array(
'class' => 'btn btn btn-default',
),
));
then in my controller:
/**
* #Route("/document/bulkdeactivate", name="documentBundle_document_bulkDeactivate")
* #Template()
*/
public function bulkDeactivateAction(Request $request) {
/*
* GET DOCUMENT FROM DB
*/
$em = $this->getDoctrine()->getManager();
$selected_documents = $request->request->all();
$deactivationForm = $this->createForm(DocumentDeactivationType::class);
$deactivationForm->handleRequest($request);
if ($deactivationForm->isValid() && $deactivationForm->isSubmitted()) {
foreach($selected_documents as $document) {
$documentR = json_decode(json_encode($document), true);
dump(count($documentR['documentlist']));
for($i=0; $i<count($documentR['documentlist']); $i++){
$doc = $em->getRepository('DocumentBundle:Document')->findOneById($documentR['documentlist'][$i]);
dump($documentR['documentlist'][$i]);
$doc->setActive(true);
$em->persist($doc);
$em->flush();
}
}
$this->addFlash(
'success',
'The selected document(s) have been deactivated!'
);
return $this->redirectToRoute('documentBundle_document_list');
}
return $this->render('DocumentBundle:Panels:ActivationPanel.html.twig', array(
'deactivationForm' => $deactivationForm->createView(),
));
}
I tried to access the wrong array positions (I didn't realize that the decoding of the ajax data sent me 3 array positions but I only wanted to access the first 'documentlist' and then get the document IDs from that one.
