Cancell file upload

Hi. How can I cancel the file upload to FileUpload? The verification condition is as follows: if the name of the uploaded file is not found in the database, then cancel its download.

protected function getFormSchema(): array
    {
        $currentTenantId = Filament::getTenant()->id;
        $UserMatchList = \App\Models\Goods\Case\UserMatchList::query()
            ->where('cabinet_id', $currentTenantId)
            ->get()
            ->map(function ($item) {
                return $item->vendor_code;
            })
            ->toArray();

        $component = Components\FileUpload::make('attachments')
            ->hiddenLabel()
            ->directory("cases/{$currentTenantId}")
            ->acceptedFileTypes(['image/jpeg'])
            ->multiple()
            ->preserveFilenames()
            ->fetchFileInformation(false)
            ->moveFiles(true)
            ->panelLayout('grid')
            ->afterStateUpdated(function (Set $set, Components\FileUpload $component, $state, $livewire) use ($UserMatchList) {

                /** @var \Livewire\Features\SupportFileUploads\TemporaryUploadedFile $file */
                foreach ($state as $file) {
                    $path = $file->getRealPath();
                    $fileName = pathinfo($path, PATHINFO_FILENAME);

                    if (!in_array($fileName, $UserMatchList)) {
                        Notification::make()
                            ->title('Filename Error')
                            ->danger()
                            ->send();
                        $file->delete();// Dont work
                        return;
                    }
                }
            });


        return [
            Components\Fieldset::make('cases')
                ->schema([$component])

        ];
    }

protected function getFormSchema(): array
    {
        $currentTenantId = Filament::getTenant()->id;
        $UserMatchList = \App\Models\Goods\Case\UserMatchList::query()
            ->where('cabinet_id', $currentTenantId)
            ->get()
            ->map(function ($item) {
                return $item->vendor_code;

                        $file->delete();// Dont work
                        return;
                    }
                }
            });


        return [
            Components\Fieldset::make('cases')
                ->schema([$component])

        ];
    }

Solution:

I think you can use a custom rule, because the file is moved when you submit the form ```php FileUpload::make('attachments') ......

Can anyone tell me? Or maybe through the

rule()

rule()

, you can somehow check the file name from the database to make a check? Can anyone help?

FileUpload::make('attachments')
...
->rules([
    fn ($state): Closure => function (string $attribute, $value, Closure $fail) use($state) {
        
        //$state is the fileupload state
        if(...) {
            return $fail('invalid.');
        }
    },
])

FileUpload::make('attachments')
...
->rules([
    fn ($state): Closure => function (string $attribute, $value, Closure $fail) use($state) {
        
        //$state is the fileupload state
        if(...) {
            return $fail('invalid.');
        }
    },
])

I tried to return the error anyway. Does not work 😦

->rules([
                fn($state): \Closure => function (string $attribute, $value, \Closure $fail) use ($state) {

                    return $fail('invalid.');

                },
            ])

->rules([
                fn($state): \Closure => function (string $attribute, $value, \Closure $fail) use ($state) {

                    return $fail('invalid.');

                },
            ])

LeandroFerreira•3mo ago

when you save the form?

NozmaDOP•3mo ago

No, when upload file

LeandroFerreira•3mo ago

add this

->afterStateUpdated(function (Page $livewire, FileUpload $component) {
    $livewire->validateOnly($component->getStatePath());
})

->afterStateUpdated(function (Page $livewire, FileUpload $component) {
    $livewire->validateOnly($component->getStatePath());
})

Yes, it works. Is it possible to do something so that this picture does not load? and there was an error as with the maximum file size

NozmaDOP•3mo ago
