Javascript force file download

Hello,

I writing a way to allow people to upload pdf files using my script. I want people to download the pdf file instead of opening it in their web browser.

I google this and found that you can do it in javascript. Anyone know how to do this in javascript?

 

I just saw this in CodeIgnitor, so maybe you can check the code for what headers they are sending.

 

Thanks NinjaWork. That was for php code. I am looking javascript version.

I might end up using that if I can't find a javascript code.

 

Hey, thanks SGBoise,

I did a little research for you, can you add these headers and see if it works:

Content-type: application/octet-stream
Content-Disposition: attachment; filename="myfile.pdf"

Code (markup):

 

here you go...a little copy and paste ;-)

<?php
header("Content-Type:application/octet-stream");
header("Content-Disposition:attachment;");
$fName = basename($_GET['file']);
fpassthru($fName);
?>

Just save that file where you store the files on the server.

If all your movies and that file were in a folder called videos, 
and you wanted to download "random.wmv", then you'd do this:

<a href="videos/filedownload.php?file=random.wmv">Cool Video!</a>

Code (markup):

You can not do this with javascript only, as the headers inside html will be read after the browser has assumed that this is a webpage.. ( and then it is too late to change them to understand it is not a page but a file for download..)

 

Looks like you also can use this with PPI

 

Hi,

I need to allow users to download mp3 file when they click on the link. But its opening the video in media player. but i dont want it to happen. It should open a save dialog to save the mp3 file. i need to use only Javascript.

Any help. Its very urgent

 

to do this you just need to make a full href to http://yoursite.com/yourfilepath/yourfile with target='_blank' in your <a href='http://yoursite.com/yourfilepath/yourfile.mp3' target='_blank'>download</a>
