I am unable to set proper headers to download file from URL.
Below code just shows content of URL in browser instead download.
$file_name = "image1.jpg";
$content_type = "image/jpeg";
$url = "http://ctan.imsc.res.in/macros/latex/contrib/incgraph/example.jpg";
header('Pragma: public'); // required
header('Expires: 0'); // no cache
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Last-Modified: '.gmdate ('D, d M Y H:i:s', filemtime ($file_name)).' GMT');
header('Cache-Control: private',false);
header("Content-type: ".$content_type);
header("Cache-Control: no-store, no-cache");
header("Content-disposition: attachment; filename=".$file_name);
header("Location: ".$url);
exit(0);
Thanks in Advance.
$originalPath = $_REQUEST['path']; //path with filename
$fileName = $_REQUEST['fileName']; // filename for downloaded file name
if (file_exists($originalPath)) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($fileName));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . filesize($originalPath));
ob_clean();
flush();
readfile($originalPath);
exit;
} else {
echo 'FILE_NOT_FOUND';
}
using this code you can save image in our server and you can download image using my upper code.
file_put_contents("Tmpfile.jpg", fopen("http://ctan.imsc.res.in/macros/latex/contrib/incgraph/example.jpg", 'r'));
this code is work fine to download from url :
set_time_limit(0);
//File to save the contents to
$fp = fopen ('file.type', 'w+');
$url = "http://yoursite.come/file.type";
//Here is the file we are downloading, replace spaces with %20
$ch = curl_init(str_replace(" ","%20",$url));
curl_setopt($ch, CURLOPT_TIMEOUT, 50);
//give curl the file pointer so that it can write to it
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
$data = curl_exec($ch);//get curl response
//done
curl_close($ch);
?>
Download file from url(in list) and save the file with last name of the url using python
import urllib.request as urllib2
import re,os
for url in open('C:\\Users\\SRINU\\Desktop\\Election_pdfs_urls\\33.txt'):
possible_urls = re.findall(r'(https?://[^\s]+)', url)
for links in possible_urls:
response = urllib2.urlopen(links.format(url.encode('utf-8')))
filename_w_ext = os.path.basename(links)
file = open(filename_w_ext, 'wb')
file.write(response.read())
file.close()

When I click on the file, I can view it in browser. When I click download, it says "failed to load the pdf document".
$file = "uploads/14204-2-002.pdf";
$finfo = finfo_open(FILEINFO_MIME_TYPE);
$mime = finfo_file($finfo, $file);
header('Pragma: public');
header('Expires: 0');
header('Content-Type: $mime');
header('Content-Description: File Transfer');
header('Content-Disposition: attachment; filename="'.basename($file).'"'));
header('Content-Transfer-Encoding: binary');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Content-Length' . filesize($file));
ob_clean();
flush();
readfile($file);
Try this one(HTML5 and no Internet explorer).
In your HTML code you can use this line:
<a href="/images/myw3schoolsimage.jpg" download="w3logo">
Specify a value for the download attribute, which will be the new filename of the downloaded file ("w3logo.jpg" instead of "myw3schoolsimage.jpg")
Moreover you can read this post of this site:
Download files from server php
I want to get information and download it through a file. But it just open a new window and show the information in it.
$filename = $this->input->cookie('merchant_id');
$timestamp = date("YmdHis",time());
$filename .= $timestamp.'.'.$fileType;
$title = mb_convert_encoding($title,'gbk','utf-8');
header('Content-type: application/octet-stream');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Content-Disposition: attachment; filename=' . $filename);
echo $title;
$ret = $this->download_model->QueryList($Req, $Resp);
$content = $this->GetDownLoadContentNew($ret['bill_list'], $fileType);
echo $content;
The GetDownLoadContentNew function just format the content.
So, why it cannot download?
I want to send a file directly to browser:
<?php
#ini_set('error_reporting', 0);
#apache_setenv('no-gzip', 1);
#ini_set('zlib.output_compression', 'Off');
#ob_implicit_flush();
$file = 'ORG.iso';
$quoted = sprintf('"%s"', addcslashes(basename($file), '"\\'));
$file_size = filesize($file);
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename=' . $quoted);
header('Content-Transfer-Encoding: binary');
header('Connection: Keep-Alive');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . $file_size);
#ob_end_flush();
set_time_limit(0);
$f = fopen($file, 'r');
while (!feof($f))
{
$buff = fread($f, 204800);
echo $buff;
sleep(1);
}
fclose($f);
It shows correct file size in Firefox and Chrome right after visitor enters the link. However it does not work in jDownloader. It seems like jDownloader is waiting for the whole script to end.
When I try a normal, static file from the same webserver- jDownloader shows file size instantly.
So obviously something is wrong with my script.
Regarding downloading files and defining the headers, I am having trouble assigning a dynamic filename to my files. When using the code below :
header("Content-Disposition: attachment; filename=test.csv");
A test.csv file is generated for download. However if I use this:
header('Content-Disposition: attachment; filename=' . $filename . '.csv');
It generates a .php file instead. Using this method also doesn't pass the Content-Disposition or filename to the header.
Full code:
session_start();
$file =$_SESSION['csvf'];
$filename = $file."_".date("Y-m-d_H-i",time());
header ( "Content-type: text/csv" );
header("Content-Disposition: attachment; filename=test.csv");
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
print($file);
exit ();
What is the correct syntax?
EDIT
Working Code after suggestions
session_start ();
$file = $_SESSION ['csvf'];
$filename =date ( "Y-m-d_H-i", time () );
header ( "Content-type: text/csv" );
header ( "Content-Disposition: attachment; filename=".$filename );
header ( 'Expires: 0' );
header ( 'Cache-Control: must-revalidate' );
header ( 'Pragma: public' );
header ( 'Content-Length: ' . filesize ( $file ) );
print ($file) ;
exit ();
I don't see the path to example.csv specified on your code, you need to give the full path to $file, i.e.:
$mySession = $_SESSION['csvf'];
//since $_SESSION['csvf'] contains the actual data you cannot use it for filename
$filename = date("Y-m-d_H-i",time()).".csv";
//write $mySession contents to file. Make sure this folder is writable
file_put_contents("/home/site/csvfolder/$filename", $mySession);
$file = "/home/site/csvfolder/$filename";
if (file_exists($file)) {
header('Content-Description: File Transfer');
header('Content-type: text/csv');
header('Content-Disposition: attachment; filename='.$filename);
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
readfile($file);
exit;
}
Please Use Like as follows,I am using this for me.
header("Content-Type: application/vnd.ms-excel; charset=utf-8");
header("Content-Disposition: attachment; filename=".$fileName);
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
In place of application/vnd.ms-excel use your file format.It is for Microsoft Excel.
Try with this:
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename=test.csv');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
readfile($file);
exit;
You can see more about download files with PHP here:
http://php.net/manual/en/function.readfile.php
Try With Below code , it's work for me
$file =$_SESSION['csvf'];
$filename = $file."_".date("Y-m-d_H-i",time()).".csv";
header ( "Content-type: text/csv" );
header("Content-Disposition: attachment; filename=".$filename);
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
print($file);
exit ();
Below is a snippet for a .zip file with some descriptions on some information that header requires, perhaps a good practice is to get the information and some validations before writing headers.
Another shorter example is also included,
// defines filename, type, path, size and a reference to file (handler)
// to set as values for file header
$filename = $survey_id . '.zip';
// define path to the file to be get file size on the next line
$filepath = [path to file]. '/' . $filename;
// used by 'Content-length'
$filesize = filesize($filepath);
// using fopen to get a file handler, 'r' for read, 'b' for binary (zip file)
$file_pointer = fopen($filepath, 'rb');
// check if file exists
if(is_file($filepath))
{
// valid file?
if($filesize && $file_pointer)
{
// some required header information to describe file, see [docs][1]
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: public");
header("Content-Description: zip file");
header("Content-Type: application/zip");
header("Content-Type: application/force-download");
header("Content-Disposition: attachment; filename=" . $filename);
header("Content-Transfer-Encoding: binary");
header("Content-length: " . $filesize);
fpassthru($file_pointer);
// close
fclose($file_pointer);
}
}
Also, checkout readfile(), a shorter snippet below
<?php
$file = 'monkey.gif';
if (file_exists($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;
}
?>
Hope this helps!
Just escape your php properly like so:
header('Content-Disposition: attachment; filename=' . time() . '.export.csv');
This example will put a UNIX timestamp prepended to the file name. Of course you could get crazy with programmatically using variables or inbuilt php functions, but this is just the example.
Here is more of an example. This file name will be produced when running this php code.
2019-05-18-contacts-main-export-by-Garrick.csv
header('Content-Disposition: attachment; filename=' . date("Y-m-d") . '-contacts-main-export-by-' . $uidName . '.csv');
I've got a web from that has two buttons for submitting, one sends an email with pdf attached, this works perfectly.
The second button is to download the pdf, this is the problem. I am saving the pdf in a temp file before download but after it is downloaded the file doesn't open and it is corrupt. The pdf is about 30KB. I have tried solutions to similar questions but always the same result, the pdf won't open.
This didn't work
$fileName = "file.pdf";
$file_name = ("temp/file.pdf");
file_put_contents($file_name, $pdf_content);
$filepath=$file_name; //file location
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="'.basename($file).'"');
header('Content-Length: ' . filesize($file));
readfile($file);
This didn't work
$path = $_SERVER['DOCUMENT_ROOT']."/temp/"; // change the path to fit your websites document structure
$fullPath = $path.$fileName;
header("Cache-Control: public");
header("Content-Description: File Transfer");
header('Content-disposition: attachment;
filename='.basename($fullPath));
header("Content-Type: application/pdf");
header("Content-Transfer-Encoding: binary");
header('Content-Length: '. filesize($fullPath));
readfile($fullPath);
exit;
This didn't work
set_time_limit(0); // disable timeout
$file = $root_path.'/full-tile-book.pdf';
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="NewName.pdf"');
header('Content-Length: ' . filesize($file));
$f = fopen($file, 'rb');
fpassthru($f);
fclose($f);
exit;
This didn't work
header('Pragma: public'); // required
header('Expires: 0'); // no cache
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Cache-Control: private', false);
header('Content-Type: application/pdf');
header('Last-Modified: ' . gmdate('D, d M Y H:i:s', filemtime($filepath)) . ' GMT');
header('Content-disposition: attachment; filename=file.pdf');
header("Content-Transfer-Encoding: binary");
header('Content-Length: ' . filesize($filepath)); // provide file size
header('Connection: close');
readfile($filepath);
exit();
The file is always in the temp folder on the server and that works fine so somewhere in the download the file is getting corrupted.
I don't care how the download is done, pdf or oclet-stream or any other way.
I removed the : Content-Type header and it works for me.
