im trying to make pdf files downloadable in my website but all im getting is the current page source(html).
the file name is correctly given but the file itself is not downloading.
ive tried various fixes found on stackoverflow but its not helping.
ive tried AddType application/octet-stream .pdf in htaccess , also ForceType.
Tried the php fix here:
How to make PDF file downloadable in HTML link?
and going through php with this:
header("Content-disposition: attachment; filename=filename.pdf");
header("Content-type: application/pdf");
readfile("filename.pdf");
and then linking to the php file, still the same.
what am i doing wrong and what information do you require to make better sense of this?
You can have serveral mistakes to check (and debug) try this
<?php
$file = ABSOLUTE_PATH_WHERE_PDF_IS_STORED.'/my.pdf'; //replace *ABSOLUTE_PATH_WHERE_PDF_IS_STORED* with your path
if (file_exists($file)) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($file));
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
readfile($file);
exit;
} else {
die("FILE [".$file."]" don't exists!");
}
?>
So i found the problem, which is of course quite obvious, i linked to the files wrongly, and since im using a cms it sent the front page source (default behaviour).
Peculiarly the html5 download attribute doesn’t work anyway.
Thank you Donald123 and PKa for answering.
You can use a tag with attribute download
<a href="path/to/file/*.pdf" download>Download this pdf</a>
Its a Quick way to do that.

So, I need a little help here. I have a site which hosts some mp3s. When users click on the download url, it links directly to a file called downloadmp3.php, which goes 2 parameters in the url...the php file is included below, and it's basically supposed to FORCE the user to save the mp3. (not play it in the browser or anything).
That doesnt happen. Instead, it seems like the file is WRITTEN out in ascii to the browser. It seems like it's the actual mp3 file written out.
Here is my downloadmp3.php file...please, what's wrong in this code.
It works on my local LAMP (Bitnami Wampstack on windows)....that is, on my local testing environment, it sends the file to my broswer, and I can save it. When I upload it to the real server, it basically writes out the mp3 file.
Here is the culprit file, downloadmp3.php...please help
<?php
include 'ngp.php';
$file = $_GET['songurl'];
$songid = $_GET['songid'];
increasedownloadcount($songid);
if (file_exists($file)) {
header('Content-Description: File Transfer');
header('Content-Type: audio/mpeg');
header('Content-Disposition: attachment; filename=' . basename($file));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
ob_clean();
flush();
readfile($file);
exit;
}
?>
By the way, this site only hosts mp3s - no other audio or file format. So, this downloadmp3.php script should ideally ask the user where they want to save this file.
Thanks for your help in advance.
I think the filename should be in quotes:
header('Content-Disposition: attachment; filename="' . basename($file) . '"');
Change the content-type value to text/plain. With this browser wont recognize it and wont play the file. Instead it will download the file at clients machine.
Seems there is too many headers. I am sure they do SOMETHING... but this code works.
This code works with MP3 files.... downloads to a file. Plays without a problem.
if(isset($_GET['file'])){
$file = $_GET['file'];
header('Content-type: audio/mpeg');
header('Content-Disposition: attachment; filename=".$file.'"');
readfile('path/to/your/'.$file);
exit();
}
You can access it with ajax call, or this:
<a id="dl_link" href="download.php?file=<>file-you-wish-to-download<>" target="_blank">Download this file</a>
Hopefully this is of some use
I am handed over a PHP Code-igniter project by my Manager, and i have not a dependable experience in PHP. Im trying to download a newly created .csv file from server. But when i download it, it does not have the content of that file, instead it shows the header stript of my .html page where im doing the whole coding.
i am trying this using Force Downloading technique, mentioned all over internet.
$filename = $_SERVER['DOCUMENT_ROOT'] . '/apps/views/style/Default/files/'.'Attendance'.'_'.strtotime("now").'.csv';
$file = $filename;
if (is_file($file) == true) {
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment; filename="'.basename($file).'"');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header("Pragma: public", true);
header("Content-Transfer-Encoding: binary");
header('Content-Length: ' . filesize($file));
readfile($file);
}
This code runs on a button click, and the File does download, but it does not show the content, but when i manually download that same file directly from Cpanel server, it has content.
When i download it through this coding, it has the html scripts.
It is because you have the code inside a page, which already have html content displayed or in buffer to be displayed, you will have to implement your force download code inside a blank page or keep the code on top of page, so it give you download of the file content only.
header('Content-type: text/csv');
header('Content-Disposition: attachment; filename="'.basename($file).'"');
readfile($file);
Problem:
After download, the file doesn't contain the data.
i.e it become blank.
So please help me for this.
<?php
session_start();
include_once 'oesdb.php';
$id=$_REQUEST['id'];
if(isset($_REQUEST['id']))
{
$sql=executeQuery("SELECT * FROM file where id=$id");
$rows = mysql_fetch_array($sql);
$file =$rows['file'];
header('Content-Description: File Transfer');
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment; filename='.basename($file));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
ob_clean();
flush();
readfile('uploads/'.$file);
exit;
}
?>
Why not create a HTACCESS file in uploads folder then states
Allow From 127.0.0.1
Deny From All
Then just create a URL, use HTML5's new download feature, do something like this:
click to download
It saves time trying to use PHP to make a download script.
try replacing this:
$file =$rows['file'];
by this:
$file = "uploads/".$rows['file'];
and this:
readfile('uploads/'.$file);
by this
readfile($file);
if still not working put the value returned by the readfile function
IMPORTANT
Please take in consideration the sql injection issues (see comment of Ondřej Mirtes)
The problem is here:
header('Content-Length: ' . filesize($file));
Content-Length receives zero value and browser downloads zero-length file, as you told him. If $file is path relative to upload/, you should do this:
header('Content-Length: ' . filesize('upload/'.$file));
Be sure that filezise() returns correct size and readfile() realy outputs it.
But the other problem is that you mentioned UPLOAD folder and using uploads. They are not same and case is important. Also, may be using relative paths in 'uploads/'.$file is not a good idea, it is better to use absolute path. For example, '/var/www/upload/'.$file.

Forcing to download a file using PHP
When we need to force user to download a file, we use header with several parameters/options. What if I use
header("location:test.xlsx");
This is working :) Is there any drawback of using this shortcut ?
This approach should solve the problems mentioned here
download.php?filename=test.xlsx
if isset ($_GET['filename']){
$filename = $_GET['filename']
}
else{
die();
}
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($file));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
ob_clean();
flush();
readfile($file);
And of course don't forget to secure this so users can't download other files
There are a few disadvantages to this method:
If the file is one the browser can read, it won't be downloaded (like .txt, .pdf, .html, .jpg, .png, .gif and more), but simply be shown within the browser
Users get the direct link to the file. Quite often, you don't want this because they can give this link to others, so...
it will cost you more bandwidth
it can't be used for private files
if it's an image, they can hotlink to it
All you're doing is redirecting to a file. This is no different than if they went to it directly.
If you are trying to force a download, you need to set your Content-Disposition header appropriately.
header('Content-Disposition: attachment');
Note that you can't use this header when redirecting... this header must be sent with the file contents. See also: https://stackoverflow.com/a/3719029/362536
Not every file is forced to download.
If you were to use that header() on a .jpg the browser won't open the download dialog but will just show the image.
I must be having a dense day. I can't seem to figure this out.
I have a page on my website which should force the download of the msi file, but I want to leave the page's html shown with download instructions.
So far, I have tried the following tag in the html (note I only have access to the body of this page)
<meta http-equiv="Refresh" content="0; URL=file.msi">
however in firefox this showed the binary file as garbled text.
Next I tried the following php inserted
$file = "file.msi";
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($file));
header('Content-Transfer-Encoding: binary');
header('Expires: 5');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
ob_clean();
flush();
readfile($file);
exit;
However this closed the tab/window and not leaving the install instructions.
finally, I tried the following back in the html:
<META HTTP-EQUIV="Content-Type" CONTENT="application/octet-stream">
<meta http-equiv="content-disposition" content="attachment; filename=file.msi" />
But this refuses to download the file.
Any pointers greatly appreciated.
Assuming Apache, if you wanted to use a .htaccess file you could add the following:
AddType application/octet-stream .msi
As per this source. You could then just link to the file.
<meta> tags apply to the page they're embedded in. They will not change how a file is downloaded, which is considered a completely separate page.
You should have something like <a href="downloadmsi.php" target="_new" />download</a> so that the download occurs in a different window than the instructions page.
I found this link that helped me create a PHP file to link to that would specify the .msi to download. Worked the first time.
Visible Download Page, downloads.php, maybe
download now
Sever Processing Page from href above, i.e. example.com/downloads/index.php
$root = realpath($_SERVER["DOCUMENT_ROOT"]);
$file_dl = $_GET['version'];
header('Content-disposition: attachment; filename='.$file_dl);
header('Content-type: application/x-ole-storage');
readfile($root.'/downloads/'.$file_dl);
Also, not sure if it was necessary, but I added to the .htaccess file: AddType application/octet-stream .msi as suggested by Marc B
