[EP-tech] Re: Check uploaded document for PDF/A compatibility

Hello,

I added two fields in document_fields.pl (val_report and val_good), but the code below (in document_validate.pl), fails to populate them. 

For checking reasons I tried to write to document-field formatdesc - also to no success.

 $document->set_value  doesn't seem to work  here....


  # CHECKS IN HERE
  #
  # PDF/A check
  my $pdf_file_path = $document->file_path;
  my $cmd = '/srv/bin/pdf-check/is-it-pdfa.sh';
  my $output = `$cmd $pdf_file_path`;         # whatever you need to do to call the command
  #my $output = "XXX";
  $document->set_value( "val_report", $output );
  #$document->set_value( "val_report", "TESTwrite to val_report NOW" );
  $document->set_value( "formatdesc", "TESTwrite to formatdesc NOW" ); # check if I can write to formatdesc
  if ($output && $output =~ m/INVALID/)       # match output indicating failure
  {
    $document->set_value( "val_good", 'FALSE' );
    push @problems, $repository->html_phrase('validate:pdf_not_ideal');
  } else {
    $document->set_value( "val_good", 'TRUE' );
  }

The cfg.d/document_validate.pl configuration file is probably what you want

https://github.com/eprints/eprints/blob/3.3/lib/defaultcfg/cfg.d/document_validate.pl


Don't forget you can use backticks to call command-line utitilites if there isn't a perl library to do the work.  Something like:


my $pdf_file_path = $document->get_main->path;
my $cmd = '/usr/local/bin/thingy';
my $output = `$cmd --file=$pdf_file_path --verbose`; #whatever you need to do to call the command
if ($output && $output =~ m/this is a bad file/) #match output indicating failure
{
        push @problems, $repository->html_phrase('validate:pdf_not_ideal');
}
