Error on Creating PDF - ERR_INVALID_RESPONSE

[milesreid]

Hi
I am having an error in creating a PDF using DomPDF from my details view.

I have tested DOMPDF in a simple script (see code below) and it works as intended, but I cannot generate the pdf within

    require 'vendor/autoload.php' ;
    use Dompdf\Dompdf;
    $dompdf = new Dompdf();
    $dompdf->loadHtml('<h1 style="color:#f00">Test PDF Render</h1>');
    $dompdf->setPaper('A4', 'landscape');
    $dompdf->render();
    $dompdf->stream("Generate 3", array('Attachment'=>0));

This script being executed from /libraries/fabrik/vendor/vendor

In my J3 application I can run mysite.com/my-menuitem/details/7/16 - this executes as intended, but the following throws an error:
mysite.com/my-menuitem/details/7/16?format=pdf
Chrome reports ERR_INVALID_RESPONSE

This is probably just a case of getting paths correct, but I cannot see where the adjustments need to be made. I did run composer as directed on github,
Thanks
Miles

This is Fabrik 3 forum, /libraries/fabrik/vendor/vendor sounds like Fabrik 4.
What do you mean with script?
Fabrik PDF is created by enabling the PDF button in form settings.

I did run composer as directed on github

To do what?

I did what was specified on github. I am a newbie to this troester, and am very much lost

Which GitHub?
Why running a script?
Which exact Fabrik, Joomla, php version?

Hi
I'm on Joomla 3.10 and PHP 7.4
Fabrik is 3.10
I downloaded the dompdf library and was running composer as it documents in https://github.com/dompdf/dompdf . my understanding was that it was necessary to require the dompdf in the default.php of my details view within components/com_fabrik/views/details/tmpl
I could not get this to work!

 

[troester]

domPDF is included in Fabrik, no need to do something on your own (as long as you are not running Fabrik 3 and php8).

Install the Fabrik library or better do a Fabrik 3 GitHub update (recommened for php7.4 anyway), which will you add the libraries automatically.

Many thanks for your help, troester - and particularly for your patience.
Everything is working fine now. I needed another pair of eyes to get me back to basics!
