Constant DOMPDF_ENABLE_REMOTE already defined

[jonnywilliamson]

Hi Barry,

I have probably a fairly unique case here, but I've come up against an issue with this great wrapper for dompdf.

I have some code, that creates a very small pdf using the loadHTML method.

Later on the code needs to call itself again with new variables and tries ones again to create a new Dompdf object and then loadHTML.

On this SECOND attempt of instantiating DOMPDF, I get the above error concerning the already defined constants.

The issue I see is in
/barryvdh/laravel-dompdf/src/Barryvdh/DomPDF/PDF.php

protected function loadConfig(){

        define("DOMPDF_ENABLE_REMOTE", true);
        define("DOMPDF_ENABLE_AUTOLOAD", false);
        define("DOMPDF_CHROOT", base_path());

[....snip....]
    }

If I do a test before defining the constants, everything works perfectly.

 protected function loadConfig(){

       if(!defined("DOMPDF_ENABLE_REMOTE")){
            define("DOMPDF_ENABLE_REMOTE", true);
        }
        if(!defined("DOMPDF_ENABLE_AUTOLOAD")){
            define("DOMPDF_ENABLE_AUTOLOAD", false);
        }
        if(!defined("DOMPDF_CHROOT")){
            define("DOMPDF_CHROOT", base_path());
        }

[....snip....]
}

Would there be any chance of an update to your code so I could update reliably in the future?

Many thanks sir.

Should be fixed in dev-master.

Also, do you use the facade or do you instantiate a new PDF object? I thought this issue didn't occur when using the facade, but not really sure.

[jonnywilliamson]

Actually I hadn't tried using the facade - I was using $pdf = new PDF();

If you want I can try it, but I see you've "fixed" it already so perhaps there's no point now!

Thanks for such a fast response. Much appreciated.
