$pdf = new FPDI();

// let's get an id for the background template
$pdf->setSourceFile('/home/user/public_html'.$pdfName);
$backId = $pdf->importPage(1);

// iterate over all pages of HTML_Generated_pdf.pdf and import them
$pageCount = $pdf->setSourceFile('/home/user/public_html/wp-content/themes/myTheme/'.$filename.'.pdf');
for ($pageNo = 1; $pageNo <= $pageCount; $pageNo++) {
    // add a page
    $pdf->AddPage($specs['h'] > $specs['w'] ? 'P' : 'L', 'Letter');
    // add the background
    $pdf->useTemplate($backId);
    // import the content page
    $pageId = $pdf->importPage($pageNo);
    // add it
    $pdf->useTemplate($pageId);

    $pdf->ImageSVG($file='images/EN-Logo.svg', $x=30, $y=100, $w='', $h=100, $link='', $align='', $palign='', $border=0, $fitonpage=false);
}

$pdf->Output($filename.'2.pdf', 'F');
