PDF out of web root and encoding error view

[brosjr]

Hi all,

 

On my project some PDF documents and images are storage outside the web public folder, so I just can't reach then just with a simple link and I need to display then on a page.

 

$fileDir = '../data/contas';

 

For images I use the code below (this solution I found on web):

 

			
$fileDir = '../data/contas/';

function data_uri($conta, $mime) 
{
$contents = file_get_contents($conta);
$base64 = base64_encode($contents);
return "data:$mime;base64,$base64";
)

<img src="<?php echo data_uri($conta, 'image/png');?>" width="720">

 

When I see the HTML code I got <img src="data:image/png;base64,/9j/4AAQSkZJRgABA...(huge amount of string)...FXYq/wD/2Q=="  width="720"> and the images are displayed correctly.

 

The problem occurs on PDF files, I use the same function, as follow below and the PDF document is not displaying, there is no error message just a gray background where the document were to be shown.

 

<EMBED SRC='<?php  echo data_uri($conta, 'application/pdf');?>#view=FitH,top&toolbar=1&navpanes=0&scrollbar=1&zoom=scale' WIDTH="720" HEIGHT="900" ALIGN="TOP"></EMBED>

 

When I look at the HTML code it shows: <EMBED SRC='data:application/pdf;base64,JVBERi0xLjIK...(huge amount of string)...YK#view=FitH,top&toolbar=1&navpanes=0&scrollbar=1&zoom=scale' WIDTH="720" HEIGHT="900" ALIGN="TOP"></EMBED>

 

Any ideia how can I show the PDF files?

 

Or there is another way to access the files outside web public folder on server to display then?

 

Thankx

I've never really tried a data uri in an embed, it could be that the browser does not support it there (or maybe the plugin that handles the embed).

 

A fairly typical method of access files outside the web root is to just create a proxy script.  Eg:

 

example.com/serveFile.php?file=blah

<?php

$file = $_GET['file'];
//Make sure you sanitize $file to ensure it points to a valid file

//do any other checks such as ensure the user is logged in and has permission if necessary

//if all checks are pass then
header('Content-type: application/pdf'); //or vary based on file type which you'll have to get somehow
header('Content-length: '.filesize($file));
header('Content-disposition: attachment; filename="'.basename($file).'"'); 
readfile($file);
?>

Thank you kicken but that worked just for downloading the pdf as file it didn't help to opening the document on the page.

 

But I thied the below object tag and it worked, not as I expected once I can't handle with it's zoom options, maybe because of encoded strings, but it's fine.

 

<object data='<?php echo data_uri($conta, 'application/pdf');?>'  type='application/pdf'  width='720'  height='900'> </object>

 

Thankx
