I'm trying to force a file download and all I get is a random string of unknown characters in the browser window. Code is included:
$file_url = "docs/$c/$path";
header('Content-Description: File Transfer');
header("Content-Type: application/octet-stream");
header("Content-Disposition: attachment; filename=$title.$type");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false); // required for certain browsers
header("Content-Transfer-Encoding: binary");
header("Pragma: public");
header("Content-Length: ".filesize($file_url));
readfile($file_url);
It's been going on for about a week, I'm going nuts. Any help is appreciated.
Thanks.
I suspect your Content-Disposition header is the problem.
Try this version instead:
header("Content-Disposition: attachment; filename=\"$title.$type\"");
I was facing the same error. Using ob_clean() and flush() helped my case. I used the code below:
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-disposition: attachment; filename='.$filename.'.pdf');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-type: application/force-download');
header( 'Content-transfer-encoding: binary' );
ob_clean();
flush();
readfile('Reports/'.$filename.'.pdf');
exit;

I Want to add download file in the site, but when I click on download It shows weird character. I dont know what the error is. I have added type application/octet-stream in my code. I think there is problem of permission but I have also set permission in c-panel :
Here is my file download code:
if(isset($_REQUEST["file"])){
$file = urldecode($_REQUEST["file"]);
$filepath = ABSPATH.'/wp-content/themes/xorisk/document_upload/'.$file;
if(file_exists($filepath)) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="'.basename($filepath).'"');
header("Content-Type: mime/type");
header('Expires: 0');
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header('Cache-Control: must-revalidate');
header('Pragma: public');
header("Content-Transfer-Encoding: binary");
header('Content-Length: ' . filesize($filepath));
readfile($filepath);
exit;
i wrote a download script that find a restricted file from server and after reading that, prepare the file for user to download it with the following headers.
header('Content-Type: application/octet-stream');
header("Content-Length: $filesize");
header('Content-Disposition: attachment; filename="'.basename($file).'"');
header('Accept-Ranges: bytes');
header('Connection: Keep-Alive');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
but sometimes with default browsers download managers, it returns download-file.php instead of filename!
for example it should return abc.zip but it returns download-file.php and download process works perfectly
any help will be appreciated
Since I don't know how you're using $file or $filesize try this instead:
$file = "abc.zip"; // adjust accordingly
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Content-Type: application/force-download");
header("Content-Disposition: attachment; filename=".basename($file));
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".filesize($file));
header("Content-Description: File Transfer");
#readfile($file);
exit();
plus, a missing readfile()
This line:
header("Content-Length: $filesize");
should read as:
header("Content-Length: ".filesize($file)); // or $filesize in your case.
Missing filesize()
I have a document hosted in a folder above public_html for security reasons - moving the files into the web root is not an option.
I'm trying to access them via a readfile() but whatever I download winds up being 0 bytes and an empty file. I think the problem is that the "Content-Length" header isn't getting a correct value because filesize($target) is giving no output.
Any thoughts? Code included:
header('Content-Description: File Transfer');
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Content-Transfer-Encoding: binary");
header("Pragma: public");
$file="../docs/$c/$path";
$size=filesize($file); //i think this line is the problem
header ("Content-Length: $size");
header("Content-Type: application/octet-stream");
header("Content-Disposition: attachment; filename=\"$filename\"");
readfile($file_url);
I don't see $file_url defined in your code. Maybe it should be $file:
header('Content-Description: File Transfer');
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Content-Transfer-Encoding: binary");
header("Pragma: public");
$file="../docs/$c/$path";
$size=filesize($file); //i think this line is the problem
header ("Content-Length: $size");
header("Content-Type: application/octet-stream");
header("Content-Disposition: attachment; filename=\"$filename\"");
readfile($file);
I also don't see $filename defined.
I have the following code in an attempt to have it so a specific file on the server is downloaded:
$file = 'upload/Order.txt';
header("Pragma: public", true);
header("Expires: 0"); // set expiration time
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");
header("Content-Disposition: attachment; filename="basename.$file);
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".filesize($file));
All that happens is it causes the browser to download a file, in my case "Order.txt", but its blank, it is just creating this file out of no where. It doesn't do anything with the "upload/" path portion of $file.
Thanks for any help, I find headers really confusing, why I can't just have "download ($file)" is beyond me.
Edit: I'll struggle over a problem for days, finally decide to ask here then immediately after fix it my self.
I changed the location of the file to be in the same as the PHP script, I'd still like to know how to make it work with them being separate however. I also added:
readfile($file);
If I alter with of these 2 changes it doesn't work.
Also slim lined it, new code:
$file = 'Order.txt';
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-Disposition: attachment; filename=$file");
header("Content-Type: application/zip");
header("Content-Transfer-Encoding: binary");
readfile($file);
you should print content of file to stdout after headers:
$file = 'upload/Order.txt';
header("Pragma: public", true);
header("Expires: 0"); // set expiration time
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");
header("Content-Disposition: attachment; filename=".basename($file));
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".filesize($file));
$handle = fopen($file, "r");
$contents = fread($handle, filesize($file));
fclose($handle);
echo $contents;
Try change this line:
header("Content-Disposition: attachment; filename='".basename($file)."';");
Generally, browsers show the image and pdf files without embedding them in html. I need some codes to make these files not to show in the browsers but make them downloadable like doc files.
Please help me out with this.
This isn't up to you, it is up to the browser.
However, you can make a suggestion as to what to do with it by setting the content-disposition header...
header("Content-Disposition: attachment; filename=\"yourfilename.pdf\"");
Read the doc on the header() function: http://php.net/manual/en/function.header.php
In case this isn't clear... this is for whatever resource is returned by the PHP document. You may need a readfile() in there to do what you are trying to do.
Set a couple of headers:
$filename = ...;
$mime_type = ...; //whichever applicable MIME type
header('Pragma: public');
header('Expires: 0');
header("Content-Disposition: attachment; filename=\"$filename\"");
header("Content-Type: $mime_type");
header('Content-Length: ' . filesize($filename));
readfile($filename);
<?php
header('Content-disposition: attachment; filename=myfile.pdf');
header('Content-type: application/pdf');
readfile('myfile.pdf');
?>
You want to send a content type header to make the browser download the file.
If you aren't' generating it dynamically, you will need to read it off the disk first.
$fullPath = "/path/to/file/on/server.pdf";
$fsize = filesize($fullPath);
$content = file_get_contents($fullPath);
header("Pragma: public"); // required
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false); // required for certain browsers
header("Content-Type: application/pdf");
header("Content-Disposition: attachment; filename=\"".basename($fullPath)."\";" );
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".$fsize);
echo $content;
try this one :
$file = 'youfile.fileextention';
if (file_exists($file)) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($file));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
ob_clean();
flush();
readfile($file);
exit;
