How do you correctly output several pages in same PDF using TCPDF?

Question

I am new to using TCPDF. I have successfully outputted one page by itself, but when I try to print many in one page using a for loop that loops through the info of all invoices nothing happens. Nothing is outputted and I debug line by line and no error pops up. I feel like looking for a needle in a haystack.

I use $pdf->AddPage(); at the beginning of each iteration and: $pdf->writeHTML($html, true, false, true, false, ''); $pdf->lastPage(); before the iteration finishes. Finally, OUTSIDE the loop, I output everything with $pdf->Output.

Is this not the correct logic?

In case you need to have a look at the code:

require_once('tcpdf/tcpdf.php');


$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);

$pdf->SetCreator(PDF_CREATOR);
$pdf->SetAuthor('Nicola Asuni');
$pdf->SetTitle('Factura CLIKEA');
$pdf->SetSubject('TCPDF Tutorial');
$pdf->SetKeywords('TCPDF, PDF, example, test, guide');
$pdf->SetHeaderData(PDF_HEADER_LOGO, PDF_HEADER_LOGO_WIDTH, PDF_HEADER_TITLE, PDF_HEADER_STRING);
$pdf->setHeaderFont(array(PDF_FONT_NAME_MAIN, '', PDF_FONT_SIZE_MAIN));
$pdf->setFooterFont(array(PDF_FONT_NAME_DATA, '', PDF_FONT_SIZE_DATA));
$pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED);
$pdf->SetMargins(PDF_MARGIN_LEFT, PDF_MARGIN_TOP, PDF_MARGIN_RIGHT);
$pdf->SetHeaderMargin(PDF_MARGIN_HEADER);
$pdf->SetFooterMargin(PDF_MARGIN_FOOTER);
$pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM);
$pdf->setImageScale(PDF_IMAGE_SCALE_RATIO);
$pdf->SetFont('dejavusans', '', 10);


$count = count($array_facturas);

for($i=0; $i<$count; $i++){


    $pdf->AddPage();

    $factura = $array_facturas[$i];
    $lineas_factura = $array_lineas_facturas[$i];

    $lineas_de_factura_cadena = "";
    $precio_total = 0;
    $iva_total = 0;

    foreach ($lineas_factura as $linea) {

        $elPrecio = $linea["precio"];
        $laCantidad = $linea["cantidad"];
        $elPvp = $elPrecio * $laCantidad;
        $elDescuento = $linea["descuento"];
        $total_linea = $elPvp - ($elPvp * $elDescuento / 100);
        $iva_total += $total_linea * $linea["iva"] / 100;
        $precio_total += $total_linea;

        $lineas_de_factura_cadena .= '
                                
                                ' . $linea["nombre"] . '
                                ' . number_format($elPrecio, 2, ",", ".")  . '€' . '
                                ' . $laCantidad . '

                                ' . number_format($total_linea, 2, ",", ".")  . '€' . '';
    }

    $subtotal = $precio_total - $iva_total;
    $precio_final = $precio_total - ($precio_total * $factura["descuento_factura"] / 100);

    $pdf->writeHTML($html, true, false, true, false, '');
    $pdf->lastPage();
}

$pdf->Output('Factura CLIKEA.pdf', 'I');

Basically, what I'm trying to do is to print several invoices in the same PDF.

How do you correctly output several pages in same PDF using TCPDF?
