Batch export support for Views data export module

It seems to work but I'm unable to override the template pdf-serialization-pdf.html.twig in batch mode (it works in Standard)

Hi @Lus

So how did you try to override the pdf-serialization-pdf.html.twig file? I am asking because this works for me. I did with theme suggestions though.

/**
 * Implements hook_theme_suggestions_HOOK_alter().
 */
function ejp_export_theme_suggestions_pdf_serialization_pdf_alter(array &$suggestions, array $variables): void {
  $suggestions[] = $variables['theme_hook_original'] . '__ejp_export';
}

I added extra views variable to pdf_serialization_pdf_header and pdf_serialization_pdf_footer theme functions.

I made my patch compatible with 2.2.0 version and fixed a few things. For example:

• We don't have to use neither
  

  $mpdf->SetHTMLHeader($header_rendered, 'O');
  

  (https://git.drupalcode.org/project/pdf_serialization/-/blob/2.2.0/src/Pd...) nor

  $mpdf->SetHTMLFooter($footer_rendered);
  

  (https://git.drupalcode.org/project/pdf_serialization/-/blob/2.2.0/src/Pd...) in getPDF() method of PdfManager class because the content override the header and footer this way.

• We have to take the export method into account because there can be batch export besides the standard one.

Additionally i aligned my patch of "Views Data Export" module to 2.2.0 version too. https://www.drupal.org/node/3204269 →
