Hello,

I'm facing a problem that I can't solve using the class fpdf within a snippet in evolution cms.
When I'm using the fpdf class in a standalone file "mypdf.php" called with a redirect
```
$modx->sendRedirect($modx->config['site_url'].'assets/snippets/mysnippet/mypdf.php');
```
with this basic code in the php file :
```
<?php
include('fpdf.php');
$PDF=new fpdf('P','mm','A4');
$PDF->AddPage();
$PDF->SetFont('Arial','',10);
$PDF->Write(12, "mytext");
$PDF->Output();
?>
```
it works fine, but I can't use TVs, $_SESSION etc.

So I tried to use a snippet with the same code inside, called from a doc with a blank template and the following settings :
Ressource type : web page
Content type : application/pdf
content output : inline element

ressource content : [!Pdf!]

and the snippet :
```
<?php
include($modx->config['base_path'].'assets/snippets/mysnippet/'.fpdf.php');
$PDF=new fpdf('P','mm','A4');
$PDF->AddPage();
$PDF->SetFont('Arial','',10);
$PDF->Write(12, "mytext");
$PDF->Output();
```
and I get nothing but a blank file (if I set the doc content type as text/html, I get a blank page)
I guess this has something to do with item 2 in http://www.fpdf.org/?lang=en but i just can't find the solution within modx evolution.

I look at all posts that seemed to deal with this issue but did'nt find any solution.

Can anyone help ?

Thank's a lot !

I've tried fpdf and never gotten on with it. I use mPDF http://mpdf1.com/ which works great for my needs. It may be worth checking that one out?

Here's some code I use to get it to work.

// mPDF(type, papersize, , , left?, right?, top, bottom, ?, ?
			// $mpdf = new mPDF('win-1252','A4','','',20,15,130,55,10,10); 
			$mpdf = new mPDF('win-1252','A4','','',20,15,100,55,10,10); 
			
			$css = file_get_contents('assets/snippets/statements/style.css','r');
			
			$mpdf->watermarkTextAlpha = 0.1;
			$mpdf->showWatermarkText = true;
			$mpdf->WriteHTML('<watermarktext content="COMPANY NAME" />');
			$mpdf->watermarkImageAlpha = 0.1;
			$mpdf->showWatermarkImage = true;
			$mpdf->SetWatermarkImage('companylogo.png');

			$mpdf->SetTitle($modx->config['site_name']);
			$mpdf->SetAuthor($modx->config['site_name']);

			$mpdf->WriteHTML($css, 1);
			$mpdf->WriteHTML($html, 2);
			
			$filename = $pagetitle.".pdf";
			
			$file = $filename;
			$mpdf->Output($file, 'F');

Sorry couldn't help you with your fpdf issue. As a last thought do you get the same result when writing out to a file? You never explained the process in which you want it to work.

Mine is a snippet which produces a PDF document from a database and emails it. Are you trying to offer a "export page to PDF?" or something? There really shouldn't be any issue on using $_SESSIONS. TV's would be down to grabbing the TV from a document.
