Apache and pdfs

Post the php here, I'm sure NF or similar here will spot the problem in no time.

Hokeydokes. I shan't post all the php code, only the relevant bit.

Our good friend pdf.php executes Print.php (I know follow how it all links together after some reading through the code)

Print.php renders the pdf like this

$pdf->Output("Invoice.pdf", "I");

Where $pdf is an instance of the Invoice class. The two arguments here are the name of the document to create, and the second argument is to do with the Content-Type.

The pertinent bit in the Output method of the invoice class looks like this

switch($dest)

	{

		case 'I':

			//Send to standard output
			if(isset($HTTP_SERVER_VARS['SERVER_NAME']))
			//if (true)

			{

				//We send to a browser

				[B]Header('Content-Type: application/pdf');[/B]

				if(headers_sent())

					$this->Error('Some data has already been output to browser, can\'t send PDF file');

				Header('Content-Length: '.strlen($this->buffer));

				Header('Content-disposition: inline; filename='.$name);

			}

			echo $this->buffer;

			break;

So we know the flag is set to "I" so the only thing that can stop this branch from working is if

if(isset($HTTP_SERVER_VARS['SERVER_NAME']))

is returning false.

This document explaining what $HTTP_SERVER_VARS actually is makes me nervous

$HTTP_SERVER_VARS [deprecated]

$_SERVER -- $HTTP_SERVER_VARS [deprecated] — Server and execution environment information
Report a bug
Description

$_SERVER is an array containing information such as headers, paths, and script locations. The entries in this array are created by the web server. There is no guarantee that every web server will provide any of these; servers may omit some, or provide others not listed here. That said, a large number of these variables are accounted for in the » CGI/1.1 specification, so you should be able to expect those.

$HTTP_SERVER_VARS contains the same initial information, but is not a superglobal. (Note that $HTTP_SERVER_VARS and $_SERVER are different variables and that PHP handles them as such)

So it looks like as I built this machine from the latest bits the php version is too high and hence I have a build problem.

Now fecking idea where next. I tried removing the if case and just setting the Content_Type anyway, but I then get an empty page loading instead.

OK NF, over to you.

 

[suityou01]

The correct (ie non deprecated code would be)

case 'I':

			//Send to standard output
			//if(isset($HTTP_SERVER_VARS['SERVER_NAME']))
			[B]if(isset($_SERVER['SERVER_NAME']))[/B]
			//if (true)

			{

				//We send to a browser

				Header('Content-Type: application/pdf');

				if(headers_sent())

					$this->Error('Some data has already been output to browser, can\'t send PDF file');

				Header('Content-Length: '.strlen($this->buffer));

				Header('Content-disposition: inline; filename='.$name);

			}

			echo $this->buffer;

			break;

Which now steps into the branch but the moment the Content_Type is set I get a blank page

I added the line

error_reporting(E_ALL);

just before the output but again I still get a blank page.

So yes it is the content type not being set correctly, but when you set it then it loads nothing at all.

I restarted apache out of desperation.

It works.

Off for a glass of vino, before coming back and pozzie repping everyone in this thread. Time for some suity loving, you better buckle up.

Well done on the debug. What a win-win, SuitYou sorted his problem and we all got his positive rep.

PHP can be a bit of a swine with the deprecated stuff. I had a fair old bit of digging and updating of code to do when I went to 5.3. I've still got some websites to switch over and check they don't barf.

Excellent news!
