yes, I would also like to merge the attached pdf files
I'm trying like this:
function Page_Exporting(&$doc)
{
return false;
}
il global code:
use Dompdf\Dompdf;
use Dompdf\Options;
use setasign\Fpdi\Fpdi;
function generaPDF($html) {
$options = new Options();
$options->set('isHtml5ParserEnabled', true);
$options->set('isRemoteEnabled', true);
$dompdf = new Dompdf();
$dompdf->loadHtml($html);
$dompdf->setPaper('A4', 'portrait');
$dompdf->render();
return $dompdf->output();
}
function Row_Export($doc, $rs)
{
$html = $rs['testorapportohtml'];
// Genera il PDF dal contenuto HTML
$pdfContent = generaPDF($html);
$rapportoId = $rs['idrapporto'];
$pdfPath = "files/rapporto_$rapportoId.pdf";
file_put_contents($pdfPath, $pdfContent);
$allegati = ExecuteRows("SELECT * FROM allegati WHERE idrapporto=".$rapportoId);
$pdfFiles = [$pdfPath];
foreach ($allegati as $allegato) {
// Costruisci il percorso del file PDF allegato
$filePath = 'files/'.$allegato['allegato'];
$pdfFiles[] = $filePath;
}
$pdf = new FPDI();
foreach ($pdfFiles as $file) {
$pageCount = $pdf->setSourceFile($file);
for ($i = 1; $i <= $pageCount; $i++) {
$tplIdx = $pdf->importPage($i);
$pdf->AddPage();
$pdf->useTemplate($tplIdx);
}
}
$mergedPdfPath = "pdf/unito_$rapportoId.pdf";
$pdf->Output('F', $mergedPdfPath);
return $mergedPdfPath;
}
if click to export pdf:
SyntaxError: Unexpected token '<', "
"... is not valid JSON

- Row_Export server event is used to export a row, not a document.
- The server events for export still uses the
$doc
to output, if you don't use it at all, the output will be wrong. - In your case you better use Row_CustomAction server event.

How do I merge all the pdf attachments of the table, with the same id, into a single file?

Currentyl, there are no pdf merging feature.
As mentioned, you should use Row_CustomAction server event for such case.
