I have a link on my web page to download a .CSV file that I have generated on the server. The code for the download is as follows:
//open/save dialog box
header('Content-Disposition: attachment; filename="inventoryData.csv"');
//content type
header('Content-type: application/excel');
//read from server and write to buffer
readfile('spreadsheet/inventory.csv');
When I open the file on the server, it looks just fine. However, when I download the file via the dialog box, it is pre-pending the HTML code for the web page to the .csv file.
Any ideas why that would happen?
If this code is in a controller action which I assume it is since you are using ZF, then you need to disable your layout and the view renderer as it will try to render a view.
Try:
public function downloadAction()
{
$this->_helper->layout()->disableLayout();
$this->_helper->viewRenderer->setNoRender(true);
//...
//open/save dialog box
header('Content-Disposition: attachment; filename="inventoryData.csv"');
//content type
header('Content-type: application/excel');
//read from server and write to buffer
readfile('spreadsheet/inventory.csv');
}
$this->_helper->layout()->disableLayout(); prevents your layout script from being rendered (assuming you use layouts), and $this->_helper->viewRenderer->setNoRender(true); tells the view renderer not to render the view script for the controller action which may contain some HTML or whitespace.
This should do the trick
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false);
header("Content-Type: application/octet-stream");
header("Content-Disposition: attachment; filename=\"inventoryData.csv\";" );
header("Content-Transfer-Encoding: binary");
Try this one:
header("Content-type: application/octet-stream");
header("Content-disposition:attachment; filename=inventoryData.csv");

So I am using PHP headers to force download a file, but when the file is saved it gets corrupted because for whatever reason the HTML code from the download page is also added into the file code/contents:
Beginning of downloaded file:
End of downloaded file:
and here is my code that forces the download, I also downloaded the same file straight from my server (FTP) and it does not have this in its file code, so I know it has to be the following code causing the problem:
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-Disposition: attachment; filename={$qfile['rfname']}");
header("Content-Type: application/zip");
header("Content-Transfer-Encoding: binary");
readfile($file['dl_path']);
I've looked around but I don't see anything pertaining to this, would anybody have an idea as to why this could be happening?
Add content type to application/octet-stream as below:
header("Content-Type: application/octet-stream");
Like Barmar said, I needed to exit();/die(); after the function readfile();.
So the fix would look like:
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-Disposition: attachment; filename={$qfile['rfname']}");
header("Content-Type: application/zip");
header("Content-Transfer-Encoding: binary");
readfile($file['dl_path']);
exit(); // Or you can use die(); here
<?php
$file = $_GET['name'];
$path = './curr/'.$file.'.pdf'; // the file made available for download via this PHP file
$mm_type="application/pdf"; // modify accordingly to the file type of $path, but in most cases no need to do so
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-Type: " . $mm_type);
header("Content-Length: " .(string)(filesize($path)) );
header('Content-Disposition: attachment; filename="'.basename($path).'"');
header("Content-Transfer-Encoding: binary\n");
readfile($path); // outputs the content of the file
?>
This is a snippet of code in file.php. I am referring to the file using:
File 1
The intent is that on click of the link, ./curr/First File.pdf should download. I do get a download, but on inspecting, it's the webpage with the pdf embedded in the file. Could anyone assist?
If you want to have just the PDF loaded, the above code is all code to be executed.
Drop all surrounding menus, header or footers. Make sure, that no HTML or any other output besides the PDF from readfile() remains, when calling this link.
Try to change the content type to :
header("Content-Type: application/force-download");
I created a form, which, when a contained button is clicked, should open a download dialog to download a certain file. The file is placed on the same server.
I tried:
header("Content-Type: application/force-download");
header("Content-Disposition: attachment; filename=" . $file . '"');
Where $file is a local path + the file name, for example c:\mypath\myfile.xls. This does not work though. It offers me a file, but its not a valid file. How else could I do that?
Note: I wrote c:\ because its still on my local machine for testing.
Thanks!
Try this
header("Pragma: public", true);
header("Expires: 0"); // set expiration time
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");
header("Content-Disposition: attachment; filename=".basename($file));
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".filesize($file));
die(file_get_contents($file));
I think file_get_contents() function is no longer work with PHP 5.0.3
Try this :
$path = "http://www.example.com/files/";
$filename = "abc.gif";
header("Content-Type:image/gif");
header("Content-Disposition: attachment; filename=".$filename);
header("Cache-control: private");
header('X-Sendfile: '.$path);
readfile($path);
exit;
PHP runs in server side, you can not download the files in clients machine.
Upload the files to server and then give that path for download.
Path must be refered from the site root...move the file
ex:
script path : C:/wamp/www/test.php
file C:/script.js
then:
if(file_exists('../../user.js'))
{
echo "OK";
}
Still a bad ideea..
I have the following code to push a zip file for download.
$filename = "ResourcePack_".time().".zip";
$destination = $basepath."downloads/$filename";
if($this->createdownload($files,$destination,false)){
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-Length: ". filesize("$destination").";");
header("Content-Disposition: attachment; filename='$filename'");
header("Content-Type: application/octet-stream; ");
header("Content-Transfer-Encoding: binary");
ob_end_flush();
#readfile($destination);
if(file_exists($destination)){
unlink($destination);
}
}
I know the createdownload function is working to generate the zip file just fine because I see the file being created on the server. The problem is file is being written to the browser as a bunch of garbage instead of opening a download stream. Am I missing something in my headers?
EDIT
I was right. My problem is not with the php, but that calling the php file that generates this code via a JQuery $.ajax call is the problem. Using $.ajax automatically sets the Accept-Encoding request header to values incompatible with zip files. So, intead of using $.ajax I just used a simple window.open javascript command to call the same php page and it works just fine with the headers.
try to put a die after the #readfile
and remove the #, to see if you have any other error related with the file reading.
i have some code doing the same thing and this works for me:
header("Pragma: public");
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-Disposition: inline; filename="' . $filename . '"');
header('Content-type: application/zip');
//header("Content-Transfer-Encoding: binary");
header("Content-Length: " . filesize($destination));
readfile($destination);
die();
try passing proper type for that file. I think its fileinfo mime type see http://www.php.net/manual/en/ref.fileinfo.php
header("Content-Type: $file_type");
Also you have semicolon after octet-stream remove it
header("Content-type: application/octet-stream");
I would to know the command in a PHP script to get in output and save a file from my site.
Thanks
See here for a good description of how to force the output of a php script to be a download.
The basics of it are:
// Set headers
header("Cache-Control: public");
header("Content-Description: File Download");
header("Content-Disposition: attachment; filename=" + $filename);
header("Content-Type: application/zip"); // or whatever the mime-type is
// for the file you want to download
header("Content-Transfer-Encoding: binary");
// Read the file from disk
readfile($full_path_to_file);
As an addition (provided by Gordon's comment), see the 1st example on the php documentation here
At the End of the files or used in clicking files, you can add this
$filesh = "check.xls";
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Content-Type: application/force-download");
header("Content-Disposition: attachment; filename=".basename($filesh));
header("Content-Description: File Transfer");
readfile($filesh);
if you got any header using problem means, top of the file you can add ob_start(); function
If you mean getting output, contents from other site or location, this what you need file_get_contents
