I have links in my web page that point to PDFs, that are in my server.
I don't want want pdfs to be viewed in the browser bur directly downlodable when a user click on the link
just set the right header info. PHP file should look something like this.
<?
header('Content-disposition: attachment; filename=huge_document.pdf');
header('Content-type: application/pdf');
readfile('huge_document.pdf');
?>
as depicted here

test.php code:
$path = 'audio.mp3';
header("Content-type: audio/mpeg");
header('Content-Transfer-Encoding: binary');
header('Content-Disposition: inline; filename="'.$path.'"');
header("Content-length: ".filesize($path));
readfile($path);
html code:
<iframe src="test.php"></iframe>
this will play the .php as a .mp3, but i will not be able to access the navigation slider in the browser media player. i click on the slider in several different places, but nothing will happen. when i change the source to "audio.mp3" i am able to control the slider again. im pretty sure that it has something to do with the headers. any idea what headers i can use to fix this?
It actually has everything to do with what browser and plugin you are using, "streaming" mp3 or media files for that matter should not be done this way. Use any of the many open source and easy to use Flash players, they handle buffering, controls, display/hidden, and everything for you, for a mp3 file on your server.
I am working on a site to get multiple pages of a book and make it one file for mobile users. The site is at http://bookgrabber.comze.com. Right now I am providing a download link to download the finished book. The download link is actually a link to downloadBook.php. Everything works fairly well and as expected, but when you click "save link as" the first word of the title of the book comes up in the save as dialog...Where is that coming from so I can alter it? It does not appear in the html of the page...
Here is what is on the downloadBook.php page:
header('Content-disposition: attachment; filename='.$_SESSION['bookName'].'.html');
header('Content-type: application/html');
echo $_SESSION['book'];
Thank you,
Todd
That's what your first header line is designed to do: tell the browser that the file should be downloaded and not displayed, and tell it what the filename should be.
header('Content-disposition: attachment; filename='.$_SESSION['bookName'].'.html');
That filename= part is telling the browser what the filename should be. It's getting cut off at the first space (only having the first word) because names with spaces should be surrounded by double quotes in a Content-disposition header:
header('Content-disposition: attachment; filename="'.$_SESSION['bookName'].'.html"');
I want to show my users PDF files. The reason why I use CGI to show the PDF is I want to track the clicks for the PDF, and cloak the real location of the saved PDF.
I've been searching on the Internet and only found how to show save dialog to the users and creating a PDF, not show the files to the users.
What I wanted for is show the users my PDF files, not creating or download the PDF.
Here is what I got form the official PHP documentation:
<?php
header('Content-type: application/pdf');
readfile('the.pdf');
?>
Also my google-search-result perl code:
open(PDF, "the.pdf") or die "could not open PDF [$!]";
binmode PDF;
my $output = do { local $/; <PDF> };
close (PDF);
print "Content-Type: application/pdf\n";
print "Content-Length: " .length($output) . "\n\n";
print $output
if you do it on ruby, please say it to me. But I'm not sure if my server support rails.
Sorry if my code is too far away from the method to show the pdf, since I don't know anything about pdf processing and how to implement this problem.
Lets assume that the users have the Adobe Reader plug-in. So, how to fix my problem?
edit : I want to show plain PDF file. My primary purpose: track my pdf files and use some fancy urls.
edit : Here's my main php code:
<?php
$file='/files/the.pdf';
header('Content-type: application/pdf');
header('Content-Disposition: inline; filename="the.pdf"');
#readfile($file);
?>
edit : Now the code is working. But the loading progress bar (on Adobe Reader X plugin) doesn't shows up. Why? Anyone can help me? Here's my main code:
<?php
$file='./files/the.pdf';
header('Content-type: application/pdf');
header('Content-Disposition: inline; filename="the.pdf"');
header('Content-Transfer-Encoding: binary');
header('Content-Length: ' . filesize($file));
#readfile($file);
?>
edit : All my problems solved. Here's the final code:
<?php
$file = './path/to/the.pdf';
$filename = 'Custom file name for the.pdf'; /* Note: Always use .pdf at the end. */
header('Content-type: application/pdf');
header('Content-Disposition: inline; filename="' . $filename . '"');
header('Content-Transfer-Encoding: binary');
header('Content-Length: ' . filesize($file));
header('Accept-Ranges: bytes');
#readfile($file);
?>
Thanks! :)
I assume you want the PDF to display in the browser, rather than forcing a download. If that is the case, try setting the Content-Disposition header with a value of inline.
Also remember that this will also be affected by browser settings - some browsers may be configured to always download PDF files or open them in a different application (e.g. Adobe Reader)
$url ="https://yourFile.pdf";
$content = file_get_contents($url);
header('Content-Type: application/pdf');
header('Content-Length: ' . strlen($content));
header('Content-Disposition: inline; filename="YourFileName.pdf"');
header('Cache-Control: private, max-age=0, must-revalidate');
header('Pragma: public');
ini_set('zlib.output_compression','0');
die($content);
Tested and works fine. If you want the file to download instead, replace
Content-Disposition: inline
with
Content-Disposition: attachment
You could modify a PDF renderer such as xpdf or evince to render into a graphics image on your server, and then deliver the image to the user. This is how Google's quick view of PDF files works, they render it locally, then deliver images to the user. No downloaded PDF file, and the source is pretty well obscured. :)
The safest way to have a PDF display instead of download seems to be embedding it using an object or iframe element. There are also 3rd party solutions like Google's PDF viewer.
See Best Way to Embed PDF in HTML for an overview.
There's also DoPDF, a Java based In-browser PDF viewer. I can't speak to its quality but it looks interesting.
You can also use fpdf class available at: http://www.fpdf.org.
It gives options for both outputting to a file and displaying on browser.
There is a simple solution using the embed tag:
<span class="fileShow">
<a href="aa.pdf" onclick="event.stopPropagation();" target="_blank">
<embed style="width:450px; height:300px; max-width:450px; max-height:300px" src="aa.pdf">
</a>
</span>
I am creating an xml file on the fly. When a user generates this file I want it to open up a download file dialog with the content that was generated. There is no actual file because it is just generated through php. Any ideas on how to do this?
This is what worked for me. In readfile('newfile.xml'); make sure to give the path of the file correctly. This php page is called from an html page with anchor tag which says - download:
<?php
header('Content-disposition: attachment; filename="newfile.xml"');
header('Content-type: "text/xml"; charset="utf8"');
readfile('newfile.xml');
?>
source: How do I force the browser to download a file to disk instead of playing or displaying it?
Send a content-disposition attachment header.
header('Content-disposition: attachment; filename=advertise.xml');
header ("Content-Type:text/xml");
//output the XML data
echo $xml;
// if you want to directly download then set expires time
header("Expires: 0");
I've created a custom solution in WordPress that will generate a CSV file to be downloaded by clicking a simple hyperlink, linked directly to this file. Instead of being prompted to download the file to the computer; the CSV opens in the the browser window instead.
FWIW I'm on Media Temple using a vanilla install of WordPress.
Send the proper mime type
header('Content-type: text/csv');
And use the Content-Disposition header to tell it to download: http://www.jtricks.com/bits/content_disposition.html
header('Content-Disposition: attachment; filename="mycssfile.csv"');
You always want to send the proper mime type, otherwise firewalls, anti-virus software and some browsers may have issues with it...
You can use PHP's header() function to change Content-type
header('Content-Type: application/csv');
header('Content-Disposition: attachment; filename="myFile.csv"');
The above code will force a prompt to the user for download. where myFile.csv should be replaced with the path to the file you want downloaded.
This works:
$filename = 'export.csv';
header('Content-type: application/csv');
header('Content-Disposition: attachment; filename='.$filename);
Also, I personally do not like links on my sites, I like buttons. If you want a button to do for the export function you can use the code below. I just thought I would post it because it took me a bit to figure out the first time :)
<input type="button" value="Export to CSV" onClick="window.location.href='something.php?action=your_action';"/>
You need to send the browser a MIME type of application/csv so it will offload the responsibility of handling the file to whatever the OS recommends (or user chooses).
In PHP (before any output is sent to the client):
header('Content-type: application/csv');
