生成HTML到PDF，并使用Laravel将生成的PDF上传到数据库？

Question

I am making an online exam web app. Where students will log in, and there will be an exam packet. Now the packets already have questions stored in the database, I have already converted the questions into HTML to PDF format and it's available to be downloaded. The question is, how will I able to get the generated PDF to also be uploaded to the database? Because the questions for each user will be in random order, and I would like each user to continue the previous exam packet once they log in, so it doesn't regenerate again.

Answer 1

You dont need to store it in database if u already have a html template of the data that are going to be included in pdf

Step 1) Download install this package composer require barryvdh/laravel-dompdf

Step 2) fter install pdf package for laravel then we must be configure it. just following littel thing. oprn your config/app.php file and set following value for providers array and aliases array

'providers' => [
    ....
    Barryvdh\DomPDF\ServiceProvider::class,
],
'aliases' => [
    ....
    'PDF' => Barryvdh\DomPDF\Facade::class,
],

Then run php artisan vendor:publish --provider="Barryvdh\DomPDF\ServiceProvider"

Step 3) Create a route

Route::get('generate-pdf', 'PdfGenerateController@pdfview')->name('generate-pdf');

Step 4) Add the logic to download a view as pdf:

$pdf = App::make('dompdf.wrapper');
$pdf->loadHTML('<h1>Test</h1>');
return $pdf->stream();
