view pdf stored on public/storage on laravel? - php

Question

My code doesn't save pdf's, I need to show it. If it's possible download it too.
<td><a name="Manual" href="{{asset('storage/app').'/'.$machineData->getManual()}}">
Manual de {{$machineData->getMachineName()}}</a></td>
On controller I have this
protected function downloadFile($src)
{
if(is_file($src))
{
$finfo=finfo_open(FILEINFO_MIME_TYPE);
$content_type=finfo_file($finfo,$src);
finfo_open($finfo);
$file_name=basename($src).PHP_EOL;
$size=filesize($src);
header("Content-Type: $content_type");
header("Content-Disposition: attachment; filename=$file_name");
header("Content-Transfer-Encoding: binary");
header("Content-Length: $size");
return true;
}
else
{
return false;
}
}
public function download(Request $request)
{
$note=$request->file('manual');
if(!$this->downloadFile(app_path(). $note))
{
return redirect("/machineIndex");
}
}
Please help, I just want to show the file, thanks!!

I believe you can achieve this with TCPDF
$pdf = new TCPDF('P', 'in', [$sizeX, $sizeY], true, 'UTF-8', false);
$pdf->SetPrintHeader(false);
$pdf->SetPrintFooter(false);
$pdf->AddPage();
$pdf->SetMargins(0, 0, 0, true);
$pdf->SetAutoPageBreak(false, 0);
$pdf->Output($outputPath, 'I');
This code would create a new pdf document, then have a look at https://tcpdf.org/ to make the necessary changes and the $pdf->Output($outputPath, 'I'); at the end will open the pdf without saving it to storage (almost like a dd).
Edit:
I wrote this with the assumption that you didn't want to save the file to storage, if the file is already saved in public/storage you can present it with a direct url to it.
You would need the symlink with php artisan storage:link then guide to where it is in the directory. For example 'laravel.test/public/pdfs/pdf1.pdf'
