I have a requirement where two pdfs need to be created at once. A for loop will not work as one file is going to be a certificate pdf. The next file is going to be an Invoice pdf. I know I am missing something simple or else its not possible to do this. I have attached a simple code to demonstrate what I mean. The files are executed on a form submission.I have made two files and then a handler file to include the two files but still only outputs on pdf.
<?php
require('fpdf/fpdf.php');
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Im a certificate');
$pdf->Output('Certificate.pdf', 'D'); //Output of the first invoice
$pdf = new FPDF(); // This is going to be the second pdf the Invoice
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Im an invoice');
$pdf->Output('This is a invoice.pdf', 'D');
//The problem is it only outputs the first one not this one
?>
