The Edit Form

Hey @David!

You’re 100% correct. I used to do this… but these days I typically just use flush() (but persist was never needed, except for new objects).

Cheers!

Hey RobinBastiaan

Yes, it's possible. You only need to make an AJAX request to your backend to fetch the form's data (as HTML or JSON if you want to style up the form on your frontend). Then, just create such endpoint for fetching the form's data.

Cheers!

Hey @Farry7

It depends on purpose. If there is a possibility that you will re-use your form in other place, than using include _form.html.twig you can include it everywhere, however if you have full template which extends your base, than you can use it only as main template of action. BTW simple templates without base can be easily updated via ajax actions!

Cheers!

Hey @Farry7!

Hmmm. Make sure you have the query surrounded by quotes - otherwise it will look like individual arguments to the command. If single quotes are working for some reason, try double-quotes. That "*" character in the query can sometimes confuse terminal systems (as it can be a special character).

Let me know if that helps!

Cheers!

Hey Gianluca,

This sounds like a problem that does not relate to the form. Could you double check that $invoice is not null and an instance of \App\Entity\Invoice in your edit() controller? You can use "dd($invoice)" or "dump($invoice); die;" in the begin of the edit(). Do you see the same error? Btw, does your Invoice entity has "invoiceNumber" property?

Cheers!

Thanks Victor,
I'm resoved like so:

public function edit(EntityManagerInterface $em, Request $request,$invoiceNumber)
{
        $invoice = $em->getRepository(Invoice::class)
            ->findOneBy(['InvoiceNumber' => $invoiceNumber]);

        $form = $this->createForm(InvoiceFormType::class,$invoice);

Hey Gianluca,

Thanks for sharing your solution with others! Yeah, you can always query for the object manually, especially in some complex cases - that's not a big deal. Glad you solved it yourself!

Cheers!

Hey Joel Bushiri

I believe the id of the article you are trying to access does not exist anymore. Could you double check that such id exists on your database?

Cheers!

Hey Carlo,

Even if you required a value for this field in the DB i.e. the field could not be NULL, you still need to allow null in your model (entity) in case you want to use Symfony Forms, that's kind of limitation. So, allow null in your strict types for this title field, I suppose you need to do it in setter/getter:

public function getTitle(): ?string
{}


public function setTitle(?string $title)
{}

And then it should work. As an alternative solution - you can use a separate model (like DTO) for your form where you will allow null for this field and then map data to your entity in case you don't want to allow null in your entity.

I hope this helps!

Cheers!

Thanks for posting and thanks Benoit L. for the reply! after reading the docs and installing the SensioFrameworkExtraBundle the magic kicked in!
I worked around it with the EntityManager but i wasn't satisfied without getting the DI working!

Hey Benoit L.

Good questions :)
Entities should be excluded from being auto-wired because they are just a data model, so you should not inject any services into their constructor

> How does the id in the url translates into the Article object?

There is a bit of magic that Symfony performs when you type-hint a controller's action with an entity class, it's called "Param converter".
If you want to know more, you can watch this episode where Ryan explains it: https://symfonycasts.com/sc...
Or, you can read the docs: https://symfony.com/doc/cur...

Cheers!

Hey Ginius

That's super simply, specially if you follow Symfony Form Best Practices. The "BP" is to render your buttons manually, so you can reuse your FormTypes easily. So, what you have to do is just to add some extra HTML for adding a cancel/back button

Cheers!

I understand what you meaning. My code is as follow:
<br /><button id="form_save" name="form[save]" type="submit" class="btn btn-success btn-sm">Save</button><br /><button id="form_close" name="form[close]" type="button" class="btn btn-sm" onclick="document.location.href='/admin/klanten/lijst';">Close</button><br />

It need going to be back to mij main list (admin/klanten/lijst the route in the controller is 'admin_company_list' How dow I jump to that part in twig/symfony?

btw, I like to use the naming from the routing. Not a hard coded url in href

You only have to render a route using twig. Probably you may enjoy watching our Twig tutorial: https://symfonycasts.com/screencast/twig

Anyway here is how:

<button id="form_close" name="form[close]" type="button" class="btn btn-sm">
    <a' href="{{ path('admin_company_list') }}" >Close</a'>
</button>

I had to add a tick to the anchor tag because it was been rendered as HTML

Thanks. Made a little change, above was not working.

Just toke the a-tag (removed the button).
Now it is working. Seems a-tag within button not working. Again thanks for you help and pointing me to the right direction

Wow, I didn't know you can't add an anchor tag inside a button, that's new to me :)
Cheers man!

Hey Dave!

We're currently talking about file uploads in our uploads tutorial - and I think what you're talking about is covered here: https://symfonycasts.com/sc...

However, the error you're seeing is a bit odd - it comes from the File validation constraint. Normally, if you choose not to upload a file and you submit, the File constraint is smart enough to see that you didn't upload anything, and it does nothing. However, in your case, it *does* seem to be validating still - except that the uploaded file is missing. My guess is that there's something "quirky" in your setup. Can you post your form and controller code? And when exactly dose this error occur?

Cheers!

the solution I found was to check if the user has uploaded any photo in the FileType if yes it updates it if not it sets the actual photo

$editUser = $this->getDoctrine()->getRepository(User::class)->find($id);

        $user = $this->getUser();
        if ($id != $user->getId())
            $this->denyAccessUnlessGranted('ROLE_ADMIN');

       $actualPhoto = $editUser->getPhoto();

        $editForm = $this->createFormBuilder($editUser)
            ->add('firstname', TextType::class, [
                'attr' => [
                    'class' => 'input-field'
                ],
                'label' => 'First Name'
            ])
            ->add('lastname', TextType::class, [
                'attr' => [
                    'class' => 'input-field'
                ],
                'label' => 'Last Name'
            ])
            ->add('username', TextType::class, [
                'attr' => [
                    'class' => 'input-field'
                ]
            ])
            ->add('mobile', TextType::class, [
                'attr' => [
                    'class' => 'input-field'
                ]
            ])
            ->add('zone', EntityType::class, array(
                'class' => Zone::class,
                'choice_label' => 'name',
                'attr' => [
                    'class' => 'input-field'
                ]
            ))
            ->add('isArchived', ChoiceType::class, [
                'choices' => [
                    'Yes' => '1',
                    'No' => '0'
                ],
                'attr' => [
                    'class' => 'input-field'
                ]
            ])
            ->add('address', TextareaType::class, [
                'attr' => [
                    'class' => 'input-field'
                ]
            ])
            ->add('photo', FileType::class, [
                'data_class' => null,
                'attr' => [
                    'class' => 'input-field'
                ],
                'required' => false
            ])
            ->add('update', SubmitType::class, [
                'attr' => [
                    'class' => 'btn btn-warning'
                ]
            ])
            ->getForm();

        $editForm->handleRequest($request);

        if ($editForm->isSubmitted() && $editForm->isValid()) {
            $editUser = $editForm->getData();
            $em = $this->getDoctrine()->getManager();
            if ($editUser->getPhoto() != null){
                $files = $editForm->get('photo')->getData();
                $filename = md5(uniqid()) . '.' . $files->guessExtension();
                $files->move($this->getParameter('uploads'), $filename);
                $editUser->setPhoto($filename);
                $this->addFlash('edit', 'Photo successfully edited');
            } else {
                $editUser->setPhoto($actualPhoto);
                $this->addFlash('edit', 'User successfully edited');
            }
            $em->persist($editUser);
            $em->flush();
            return $this->redirectToRoute('editUser', array('id' => $id));
        }

        return $this->render('Admin/editUser.html.twig', [
            'edit' => $editForm->createView(),
            'photo' => $editUser
        ]);

Hey dave!

Yep, that works fine! In the file uploads tutorial, we use an "unmapped" field, which is kinda nice, because the file upload doesn't override a property on your entity. But, both totally work!

Cheers!
