Good afternoon
I need help with the html2pdf, I want to automatically fill some fields of the document but doing tests and I do not detect the variables, This is the one that shows the data in the pdf
<!DOCTYPE HTML>
<?php
session_start();
if (!isset($_SESSION['user_login_status']) AND $_SESSION['user_login_status'] != 1) {
header("location: login.php");
exit;
}
require_once ("config/db.php");
require_once ("config/conexion.php");
$active_prestamos="active";
$title="Prestamos | Simple Stock";
?>
<HTML lang="es">
<HEAD>
<meta charset="UTF-8">
<title>Generar PDFs con PHP</title>
<style type="text/css">
h2{
color:darkslateblue;
}
</style>
</HEAD>
<body>
<h2> hola</h2>
<?php
$count_query = mysqli_query($con, "SELECT count(*) AS numrows FROM $sTable $sWhere");
$row= mysqli_fetch_array($count_query);
echo $orden=$row['orden'];?>
</body>
</HTML>
and this is the one who calls him
<?php
require __DIR__.'/vendor/autoload.php';
use Spipu\Html2Pdf\Html2Pdf;
ob_start();
require_once 'pdf2.php';
$html = ob_get_clean();
$html2pdf = new Html2Pdf('p','A4','es','true','UTF-8');
$html2pdf-> writeHTML($html);
$html2pdf->output('pdf_generated.pdf');
?>
and the error
(!) Notice: Undefined index: order in C: \ wamp64 \ www \ inventory \ pdf2.php on line 54 Call Stack
