I know this question has been asked, but the solutions offered are not working for me. I am able to download PDFs, but Adobe Reader is telling me it's either corrupt or decoded improperly. Does anyone have an alternative solution, or possible fix?
$path = "http://www.laerdalmail.com/discoversimulation/downloads/needs_assessment_form.pdf";
header('Content-Type: application/pdf');
header("Content-Transfer-Encoding: Binary");
header("Content-disposition: attachment; filename=needs_assessment_form.pdf");
readfile($path);
exit;
readfile should be given a filesystem path, not a URL. something like this:
$path = '/websitefolder/discoversimulation/downloads/needs_assessment_form.pdff';
// or
$parh = 'c:\something\needs_assessment_form.pdff';
Try adding in content length too:
header('Content-Transfer-Encoding: binary');
header('Content-Length: ' . filesize($path));

I am trying to force download a file in my php program under a new name (new_name). I am changing the file name but keeping the extension the same as roginal file. This is part of my code:
$original_filename = "attachments/20180315.log";
$new_filename = "new_name." . pathinfo($original_filename, PATHINFO_EXTENSION);
header("Content-Length: " . filesize($original_filename));
header("Content-Transfer-Encoding: binary");
header('Content-Disposition: attachment; filename="' . $new_filename . '"');
header('Pragma: no-cache');
readfile($original_filename);
exit;
My download is working fine when I am downloading a text file (i.e. in example above 20180315.log is a text file). When I try to do the same with a binary file (such as pdf) I am getting an empty new_name.pdf.
Any suggestion?
I have always found the exact headers required to be a bit messy and dependent on the browser, there are a lot of options, and you will see a lot of variations posted, so i suggest the following, but you may need to just test a number of combinations until you get it right, and i suggest making sure you test it on as many browsers as you can.
header('Content-Type: application/octet-stream');
header("Content-Transfer-Encoding: Binary");
header("Content-disposition: attachment; filename=\"" . $new_filename . "\"");
readfile($original_filename);
I am trying to download a file. I am using IE11. I have tried several methods to do this. Currently I am trying to use the header with Content-Disposition method. I have tried to do this a few different ways according to other answers people have given. And it does download. But instead of downloading the file I point it to, it downloads the file it is written in. So if I tell it to download example.txt in my test.php file. It will only download test.php.
These are the methods I have tried:
This one is written in test.html:
<?php
$filename = "example.txt"
header('Content-Type: text/plain');
header('Content-Disposition: attachment; filename="' . basename($filename) . '"');
?>
I've also tried making it a button:
BUTTON
Where download.php is:
<?php
$file = $_GET['file'];
header('Content-type: audio/mpeg');
header('Content-Disposition: attachment; filename="'.$file.'"');
?>
I tried this:
<?php
header('Content-Type: application/download');
header('Content-Disposition: attachment; filename="example.txt"');
header("Content-Length: " . filesize("example.txt"));
$fp = fopen("example.txt", "r");
fpassthru($fp);
fclose($fp);
?>
And this:
header("Content-Disposition: attachment; filename=\"" . basename($File) . "\"");
header("Content-Type: application/force-download");
header("Content-Length: " . filesize($File));
header("Connection: close");
There are many more slight variations and mix and matching that I have tried. All have the same problem that the .html or .php file downloads rather than example.txt. Does anyone know why this would happen? Is something not supported in IE11? I do not think it is a syntax error simply because most of these I copied from other answers online. I have tried with example.txt existing and not existing, in this folder and other folders.
EDIT: So it turns out that these all work, I was just using them wrong. I had been trying to make isolated files to run this code so I could test it without interference from the rest of the functions on my website, but this left the php files without the resources they needed to actually run properly. When I put the code into the actual files on the website it worked perfectly. smh
Try this :
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Length: ' . filesize($File));
header('Content-Disposition: attachment; filename=' . basename($File));
readfile($File);
exit;
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
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.
I have an excel file that i want a user to be able to download from my server. I have looked at a lot of questions on here but i cannot find a way to correctly download the file w/o corruption. I am assuming it is the headers but i haven't had a working combination of them yet. This is what i have right now and in the corrupt file that i receive i can see the column names of the spreadsheet i want but its all messed up.
$filename = '/var/www/web1/web/public/temporary/Spreadsheet.xls';
header("Content-type: application/octet-stream");
header("Content-type: application/vnd-ms-excel");
header("Content-Disposition: attachment; filename=ExcelFile.xls;");
header("Pragma: no-cache");
header("Expires: 0");
readfile($filename);
edit: Solution I forgot to add that i was using Zend and it was corrupting the files when trying to use native php methods. My finsihed code was to place a link to another action in my controller and have the files download from there
public function downloadAction(){
$file = '/var/www/web1/web/public/temporary/Spreadsheet.xls';
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment; filename="Spreadsheet.xls"');
readfile($file);
// disable the view ... and perhaps the layout
$this->view->layout()->disableLayout();
$this->_helper->viewRenderer->setNoRender(true);
}
try doing it this way
ob_get_clean();
echo file_get_contents($filename);
ob_end_flush();
For one, only specify Content-Type once. You can use the excel-specific header but the generic application/octet-stream may be a safer bet just to get it working (the real difference will be what the browser shows the user with regards to "what would you like to open this file with", but basic browsers can rely on the extension as well)
Also, make sure you specify Content-Length and dump the size (in bytes) of the file you're outputting. The browser needs to know how big the file is and how much content it's expecting to receive (so it doesn't stop in the middle or a hiccup doesn't interrupt the file download).
So, the entire file should consist of:
<?php
$filename = '/var/www/web1/web/public/temporary/Spreadsheet.xls';
header("Content-Disposition: attachment; filename=ExcelFile.xls;");
header('Content-Type: application/octet-stream');
header('Content-Length: ' . filesize($filename));
header("Pragma: no-cache");
header("Expires: 0");
#readfile($filename);
$file_name = "file.xlsx";
// first, get MIME information from the file
$finfo = finfo_open(FILEINFO_MIME_TYPE);
$mime = finfo_file($finfo, $file_name);
finfo_close($finfo);
// send header information to browser
header('Content-Type: '.$mime);
header('Content-Disposition: attachment; filename="download_file_name.xlsx"');
header('Content-Length: ' . filesize($file_name));
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
//stream file
ob_get_clean();
echo file_get_contents($file_name);
ob_end_flush();
