How do you write a php vairable to PDF using FPDF library?

45 32bit

I've tried using the following code to write a variable to a PDF file, but it only returns a blank PDF. How do you write a php variable to a library using the FPDF library?

Expand|Select|Wrap|Line Numbers

 
<?php

session_start();

require('../fpdf.php');

if (isset ($_POST['sig'])) {

$_POST['sig'] = $SESSION['sig'];

$pdf = new FPDF();

$pdf->AddPage();

$pdf->SetFont('Arial','B',16);

$_SESSION['sig'] = $sig;

$pdf->Cell(40,10, $sig);

$filename = '/var/www/html/foo/foo.pdf';

$pdf-> Output($filename, 'F');

}

session_destroy();

exit;

?>

<!DOCTYPE html>

<body>

<br>&nbsp;<br>&nbsp;

<form action="" method="post'>

<label for "sig">Signature: </label>

<input type="text" name="sig" placeholder="your signature here" id="sig" required>

<br>&nbsp;<br>&nbsp;

<input type="submit" value="Sign Document">

</form>

</body>

</html>

You seem to sending a blank $sig in to the Cell method.

Change this:

Expand|Select|Wrap|Line Numbers

 
$_SESSION['sig'] = $sig;

$pdf->Cell(40,10, $sig);

to:

Expand|Select|Wrap|Line Numbers

 
$sig = $_SESSION['sig'];

$pdf->Cell(40,10, $sig);

See if that works. :)

Yep, that was the problem. A simple oversight on setting the var.
