Download PDF using Spatie Laravel-PDF on table action

I am trying to download a PDF generated from a blade view. I tried DOMPDF and it works fine, but I would like to use Spatie's PDF which has better funcionality. I added the PDF to the table action, but the button just spins and nothing gets returned. Is there a way to convert the PDF to a stream to make it downloadable or?

Action::make('download')
                    ->action(function (Invoice $record) 
                        {
                            return pdf()->view('pdf.invoice', ['invoice' => $record])
                                ->format('a4')
                                ->name('your-invoice.pdf')
                                ->download();
                        })
                    ->iconButton('heroicon-o-document-arrow-down')
                    ->icon('heroicon-o-document-arrow-down')
                    ->label('Preuzmi PDF'),

Solution:

I managed to do it `return response()->streamDownload(function () use ($record) { echo base64_decode(Pdf::view('pdf.invoice', ['invoice' => $record]) ->format('a4')...

I am trying to do it this way, but no luck. Any ideas?

return response()->streamDownload(function () use ($record) {
                                Pdf::html('<p>test</p>')
                                    ->format('a4')
                                    ->name('your-invoice.pdf');
                            }, 'test' . '.pdf');

That's because you are not returning a file blob I believe. I end up saving to a tmp folder adn then providing the filepath for download and deleting on download

Prosp30OP•9mo ago

That is my backup idea, I am trying to avoid it if it's possible

toeknee•9mo ago

I couldn't figure out a way quickly last time, It's how the PDF rendering engine returns the stream IIRC

Prosp30OP•9mo ago

I'll try it today, I have an idea but I doubt it'll work

I managed to do it

return response()->streamDownload(function () use ($record) {
                                echo base64_decode(Pdf::view('pdf.invoice', ['invoice' => $record])
                                    ->format('a4')
                                    ->footerView('pdf.invoicefooter')
                                    ->name('your-invoice.pdf')
                                    ->base64());
                            }, 'test' . '.pdf');

Ahhh base64x handy

Prosp30OP•9mo ago

yeah, but it works 😄 Let me know if it works for you

ralphjsmit•8mo ago

Thanks for this! The echo and base64 part were very helpful tips. For reference, I just implemented PDF download using Spatie/laravel-pdf from an action like this:

Tables\Actions\Action::make('download_order_invoice')
    ->icon('heroicon-o-arrow-down-tray')
    ->label('Download invoice')
    ->action(function (Order $order) {
        $pdfBuilder = Pdf::view('pdfs.order-invoice', ['order' => $order])
            ->format(Format::A4)
            ->name("order-{$order->uuid}.pdf");

        return response()->streamDownload(function () use ($pdfBuilder) {
            echo base64_decode($pdfBuilder->download()->base64());
        }, $pdfBuilder->downloadName);
    }),

Tables\Actions\Action::make('download_order_invoice')
    ->icon('heroicon-o-arrow-down-tray')
    ->label('Download invoice')
    ->action(function (Order $order) {
        $pdfBuilder = Pdf::view('pdfs.order-invoice', ['order' => $order])
            ->format(Format::A4)
            ->name("order-{$order->uuid}.pdf");

        return response()->streamDownload(function () use ($pdfBuilder) {
            echo base64_decode($pdfBuilder->download()->base64());
        }, $pdfBuilder->downloadName);
    }),

This was very useful for me too! I just wanted to check if you know how to make the action show the pdf in the browser without downloading? I tried using ->stream() instead of ->streamDownload() like this:

Action::make('downloadPdf')
  ->label('Download Pdf')
  ->icon('heroicon-o-arrow-down-tray')
  ->action(function (Component $livewire) {
      $records = $livewire->getTableRecords();

      $pdfBuilder = Pdf::view('filament.pdf.group-orders', [
          'records' => $records,
      ])
          ->landscape()
          ->margins(0, 0, 0, 0)
          ->format('a4')
          ->name("test.pdf");

      return response()->stream(function () use ($pdfBuilder) {
          echo base64_decode($pdfBuilder->base64()); 
      }, 200, [
          'Content-Type' => 'application/pdf',
          'Content-Disposition' => 'inline; filename="test.pdf"'
      ]);
  }),

Action::make('downloadPdf')
  ->label('Download Pdf')
  ->icon('heroicon-o-arrow-down-tray')
  ->action(function (Component $livewire) {
      $records = $livewire->getTableRecords();

      $pdfBuilder = Pdf::view('filament.pdf.group-orders', [
          'records' => $records,
      ])
          ->landscape()
          ->margins(0, 0, 0, 0)
          ->format('a4')
          ->name("test.pdf");

      return response()->stream(function () use ($pdfBuilder) {
          echo base64_decode($pdfBuilder->base64()); 
      }, 200, [
          'Content-Type' => 'application/pdf',
          'Content-Disposition' => 'inline; filename="test.pdf"'
      ]);
  }),

But this still just downloads the pdf file.

No idea tbh, perhaps you can look on how this is achieved in a generic Livewire component

nowak•8mo ago

I ended up just creating a test route for my view in web.php:

Route::get('/test-pdf', function () {
  $records = GroupOrder::get();  

  return view('filament.pdf.group-orders', [
    'records' => $records
  ]);
});

Route::get('/test-pdf', function () {
  $records = GroupOrder::get();  

  return view('filament.pdf.group-orders', [
    'records' => $records
  ]);
});

As I just wanted to see the output without needing to download the pdf to check changes during development.

ralphjsmit•8mo ago

Makes sense, I generally have a /debug route in my applications that's only available locally (and on production perhaps for admins), that's helpful sometimes a well

nowak•8mo ago

Ahh yeah that sounds really helpful! Thanks for the tip!
