MPDF integration

[Pepita73]

Is your feature request related to a problem? Please describe.

The mpdf package use self temp directory like vendor/mpdf/mpdf/tmp. Usually the vendor directories not writable for php (cli or web), only readable. So we get warning and empty pdf file. Temporary files directory "...vendor/mpdf/mpdf/src/Config/../../tmp" is not writable But PHPWord settings can store this configuration.

Describe the solution you'd like

change line here: https://github.com/PHPOffice/PHPWord/blob/develop/src/PhpWord/Writer/PDF/MPDF.php#L56

return new $mPdfClass(['tempDir' => Settings::getTempDir()]);

Additional context

We use word template with header and footer section, but - if hacking the tempDir - these sections not transferred to the pdf file. If you can, please fix it also.

You can create your own writer to save pdf from word

final class MyMPDF extends \PhpOffice\PhpWord\Writer\PDF\MPDF
{
    protected function createExternalWriterInstance()
    {
        $mPdfClass = $this->getMPdfClassName();

        return new $mPdfClass([
            'tempDir' => \PhpOffice\PhpWord\Settings::getTempDir(),
        ]);
    }

    private function getMPdfClassName(): string
    {
        if ($this->includeFile != null) {
            // MPDF version 5.*
            return '\mpdf';
        }

        // MPDF version > 6.*
        return '\Mpdf\Mpdf';
    }
}

and call it:

$phpWord = \PhpOffice\PhpWord\IOFactory::load($filePath);
Settings::setTempDir(sys_get_temp_dir());

$mpdfWriter = new MyMPDF($phpWord);
$mpdfWriter->save($filePath);
