Pdf stream() doesn't work on submit() custom page

Hello, I have a custom page, where I have a search form, but I want a PDF to open when I click send. But it's not working, I guess it will be done another way, but I don't know which one. I need to open the pdf in another tab and that's it, I don't want to download it directly. Can somebody help me? thanks Submit custom page:

public function submit()
    {
        $teacher = Employee::find($this->data['professor']);
        $sessions = $teacher->sessions()->where('course_id', $this->data['course'])->get();
        
        if (!$this->data['course']) {
            return Notification::make()->duration(12000)->title("Selecciona un/a curs per seguir")->danger()->send(); 
        }
        if (count($sessions) == 0) {
            return Notification::make()->duration(12000)->title("No hi ha sessions per generar informe")->danger()->send(); 
        }
        $pdf = PDF::loadView('pdf.report-hours-kms', ['data' => $sessions,'teacher' => $teacher]);

        return $pdf->stream();       
    }

If you want it in a new tab, you need a normal browser link that opens a new page and that page streams the PDF.

Yeah I tend to use:

 return response()->streamDownload(function () use ($pdf, $path, $filename) {
                        echo $pdf->output();
                        File::delete($path.$filename);
                    }, $filename);

 return response()->streamDownload(function () use ($pdf, $path, $filename) {
                        echo $pdf->output();
                        File::delete($path.$filename);
                    }, $filename);

Thanks but If I do like toeknee, it downloads, what I want is for the pdf to open in the browser

toeknee•9mo ago

Then, you can have a custom URL which allows you to stream it on a new page instead

But I'm not saving the pdf, I just want to show so that they decide to download or print, or have I misunderstood?

awcodes•9mo ago

you can't show a pdf without saving it first. the browser has to have a url to show it. just like an image.

But in Laravel I have always shown it with $pdf->stream() without saving it. Is it a filament thing then? It's about learning why it happens, thanks

awcodes•9mo ago

how were you displaying the stream?

astronomic•9mo ago

In Laravel I always did like this:

$pdf = PDF::loadView('pdf.report-hours-kms', ['data' => $sessions,'teacher' => $teacher]);

        return $pdf->stream();

toeknee•9mo ago

They are building it with domPDF into tmp and steaming it basically

astronomic•9mo ago

Yes, I use domPDF. P.D: I'm a woman 😉

toeknee•9mo ago

Apologise for the assumption

astronomic•9mo ago

There's no problem 😉

So you can do:

return response()->stream(function () use ($pdf, $path, $filename) {
                        echo $pdf->output();
                        File::delete($path.$filename);
                    }, $filename);

return response()->stream(function () use ($pdf, $path, $filename) {
                        echo $pdf->output();
                        File::delete($path.$filename);
                    }, $filename);

But I doubt you want that. So instead, move the PDF Building into a new controller and have the url of the action open the new url which contains the id of the file you are bullding? if it's live / on the fly, you will need to save it, view it and setup a command to auto-clear the tmp pdf folder

I think the issue is that you are in the context of a livewire request. Maybe some insight here. https://livewire.laravel.com/docs/wire-stream

Laravel

wire:stream | Laravel

A full-stack framework for Laravel that takes the pain out of building dynamic UIs.

awcodes•9mo ago

nevermind, the tag says your on v2. this won't help since stream is a livewire v3 feature.

Dennis Koch•9mo ago

Livewire handles streamed data as a download. That's just the way downloads in Livewire work. That's why you need a separate page where you stream the data, so you can open it in a new tab.
