I'm familiar with creating wordpress plugins. I tried hard to make fpdf plugin to create pdf file from php contents, but IT didn't work
I now that :
require_once("fpdf.php");
should comes at the top of my file, and I think that is my main problem
below is how to create a simple pdf file from php script using fpdf:
require('fpdf.php');
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
What I should do to make it work?
