Composer require gives errors.

[MrBean14]

Hi all,

I'm quite new with laravel and wrote my first app.
As I used FDPF for many years in the normal PHP way, I wanted to import it in this laravel app too.

I'm using Laravel 5.4.33 with PHP 7.0 but when I run the "composer require barryvdh/laravel-dompdf" command, I get following issues. I have followed many "possible solutions" but still it is not working.

Oh, BTW, I'm using Scotch.box ...

This is the error 👍

`vagrant@scotchbox:/var/www/public/plevoets$ composer require barryvdh/laravel-dompdf
Using version ^0.8.1 for barryvdh/laravel-dompdf
./composer.json has been updated

You can also run php --ini inside terminal to see which files are used by PHP in CLI mode.

Looks like you need to enable the ext-dom PHP extension. Which may mean simply uncommenting that line in your php configuration file, or installing the extension. I've not used Scotch.box but here is what Google found:

scotch-io/scotch-box#334

Hi, thanks for your answer.
Just after my request I found a document describing to install php7.0-xml.
The error above was then solved and I was able to run the "composer require".

Then, in my config.app.php, I added :

Barryvdh\DomPDF\ServiceProvider::class,
'PDF' => Barryvdh\DomPDF\Facade::class,

Then I tried to put following code in my Controller to do a quick test :

use Barryvdh\DomPDF\PDF;
...
$facturen = Factuur::all();
$pdf = PDF::loadView('pdf.facturen', $facturen);
return $pdf->download('invoice.pdf');

Unfortunately I now get following error when opening the view 👍

_(1/1) FatalThrowableErrorClass 'DOMDocument' not found

in Dompdf.php (line 488)
at Dompdf->loadHtml('', 'UTF-8')in PDF.php (line 96)
at PDF->loadHTML('', null)in PDF.php (line 124)
at PDF->loadView('pdf.facturen', object(Collection))in Facade.php (line 31)_

I started looking around and somebody adviced me to try the code :

dd(class_exists('DOMDocument'));

This results to false.

I do not find the way to solve it.
In my php.ini I can not find back this extension.

Best regards,

Davy
